Not mentined are medical and agricultural possibilities of cheap electronics, printed electronics etc. Cheap medical tech in the form of printed electronics or microcontrollers or cheap processors etc. For example electronic thermometer manufactured with roll printed electronics and almost without cost per unit, that can be given away for free in third world and mass produced millions (or billions) of units. That is one example of health care cheap tech. Applications of agriculture also can benefit with cheap roll printed electronics and other cheap microprocessor tech. Third world countries need this kind of cheap (almost no cost per unit) tech that can be useful, health care / medical tech and agriculture are perhaps the most important sections of cheap electronics products and techiques but left unnoticed by me in earlier posts. PragmatIC is firm that has manufactured ARM cortex M0+ processor using roll printed electronics, at 1 micron process (transistors are 1 micron / 1000 nanometers wide). If microprocessors are possible to manufacture at 1 micron process using roll printing, that opens totally new possibilities of cheap microprocessors manufactured almost at no cost. Old x86 (Pentium) style processors from 1990s (Pentium Pro, Pentium 2 or 3), or old ARM designs from 1997 - 1999, old DSP designs, old FPGAs (or “coarse grained reconfigurable arrays”), microcontrollers, GPUs, GPGPUs etc. can be made effectively and almost no price. Only drawback is that because those old designs were made using 500nm, 350nm, or 250nm process, the new roll printed versions are 4 - 16 times larger and slower than their silicon chip counterparts. They are also aimed to be used devices that are charged with solar panel etc. and used in enviroment where electricity is rare, so mobile (low power) versions of these processors are needed which slowes down them even more. If solar panel (roll printed cheaply also) is used with these processors, perhaps small roll printed lamp (OLED or other cheaply manufactured lamp) is also given so small light can be used at nights in places where normally is not electricity. Other electric charging methods instead of solar panel like heat can also be used if they are more effective. Because these roll printed processors are large and slow efficiency improvements, like unum floating point units and other can be used. Unum is IEEE standard (unofficial) “extension”. And because unum offers accuracy improvement over standard floating point system using hardware and not complicated software accuracy improvement, that accuracy can be used to several FP numbers “inside each other” representation and increase information density even more, so that one (unum) FP number can have dozens other FP numbers inside itself (inside extented mantissa accuracy), these other FP numbers also other FP numbers inside itself, until accuracy potential is used, now “compression ratio” is hundreads or thousands FP numbers inside just one. In text “Hybrid hardware/software floating-point implementations for optimized area and throughput tradeoffs” 2017 is software/ hardware FP approach that can be perhaps used with unum etc. computing. Other ways to improve slow 1000 nanometer processor is to use manycore designs like Kalray, Adapteva Epiphany etc, chinese Loongson / Godson etc. that can use (almost) regular Linux or Windows. There are also designs that require special operating system and are not standard compatible, like “processor-in-memory” designs, Green Arrays processor, systolic arry processor, chinese UPU Harmony CPU/GPU hybrid etc. If they are more effective than standard x86 or ARM they can be used, perhaps in some special application. The Mill processor is Linux / Windows compatible and offer good effectiveness but is not released yet. If processor has big transistor count and it is manufactured at 1000nm roll printing, it would be very large. But roll printed big area but thin processors can be folded like hankercief so overall diameter is not much bigger than conventional processors. Processors must be designed or their design slightly altered so that folding is performed smoothly. One processor type other than ARM or x86 is Cell processor (Playstation 3). It was manufactured at 90nm process and has 240mm2 area so 1000nm version will be 120 times larger and 120 times slower 12 X 15 cm ( 4,7 X 6 inch) “chip” with only about 2 GFLOPS speed versus 200 GFLOPS of “real” Cell processor, and still consuming about 65 - 100 W power. But manufactured almost at no cost. Intel teraflops chip has 100 million transistors and 274mm2 area at 65nm process, so 1000nm version will 225 times slower and larger 25 X 25 cm (10 X 10 inch) and only 8 GFLOPS speed. Intel sigle chip cloud computer has teraflops speed, made at 45nm, 567mm2 area and 1,3 billion transistors. 1000nm will be almost 500 times larger, and slower, 53 X 52 cm about 2,5 GFLOPS. Folded to smaller size 4 X 5 foldings this “chip” has 13 X 10 cm diameter (4 X 5 inch). If Intel teraflops chip is manufactured with same area efficiency as Single Chip Cloud Computer perhaps 480 core version of it is possible instead of 80 cores, 600 million transistors at about 600mm2, same size and foldings like SCCC so it is about 50 X 50 or 60 X 60cm when roll printed at 1000nm process, speed about 50 GFLOPS, teraflops chip can be used in servers only because teraflops chip uses non- standard structure that has no operating system compability. Or using instead SCCC with Xeon Phi structure with 48 cores. That is like “poor man s Xeon Phi”, made at 1000nm process. Smaller roll printed ARM and x86 (mobile) chips that use less power can be used in hand held Personal Digital Assistant type device. Processor, display, and battery is all manufactured using roll printing, and solar panel also that brings electric power. If cost is 0,01 dollar per item that is 0,04 dollars together. Memory is also needed, but roll printing is not perhaps used because NAND flash RAM price is 4,8 dollars for 128 gigabytes according to dramexchange.com, or 0,037 dollars per gigabyte, so 300 megabytes is about 0,01 dollars. This traditional silicon memory can be used in hybrid conjuction with roll printed processor circuit as cache memory etc., slow memory speed is not a problem because processor is slow also. And use mask ROM or flash RAM cheap memory as main memory if it is cheap enough. Roll printing must use hybrid printing (ordinary silicon memory circuit printed to plastic surface together with roll printed circuits). If roll printed memory is better (cheaper) than traditional silicon memory then roll printing must be used also for memory. Mask ROM is cheaper than RAM, so using it, also in memory “card” or whatever outside memory this device uses. Using cheap mask ROM like old “ROM pack” of 1980s computers make cheap outside memory possible (together with RAM memory, if outside RAM memory is needed). Total cost (processor, display, perhaps only black and white display, keyboard simply roll printed also, no touchscreen perhaps, battery, solar panel, all roll printed, plus memory) is about 0,05 dollars, or even cheaper if manufactured billions of units. Audio is through headphones, headphones are made using roll printing also, acoustic elements roll printed, super cheap. Any electric contact surfaces are not with regular jacks but thin roll printed flat surface contact jacks, super cheaply made. 5 million dollars is enough for 100 million devices. These can be distributed in third world countries. These have no internet connection, no radio frequency or internet bus contacts, they are just personal digital assistant, game console, video / MP3 player type devices. Only way to bring information to them is cheap (perhaps roll printed) memory “card”, either RAM or mask ROM or both. These devices have large mask ROM memory and small RAM memory inside. ROM includes large “info pack” of healthcare, education, housing, clothing, governmental public information etc. Also educational section of device can be very large, like educational tablet PCs for children that are being manufactured in India and China. Better versions of these devices have internet (radio frequency) connection, but they are more expensive (“real” phones and tablet PCs, with “real” silicon chip CPUs and SoCs made with silicon wafers, but with roll printed displays, batteries etc.), and are connected to zeronet (cost free internet for development countries). Manufacturing cost of internet devices is about 5 - 10 dollars, but they also are commercially sponsored and no cost to customer, because commercially sponsored (zeronet) internet line costs more than these devices per year. Those cheaper PDA style devices can however be distributed to areas that have no internet connection, and they are much cheaper. Old abondonware (games etc.) can be used with them, like old VIC 20, Atari 2600 or Sinclair Spectrum games that have only few kilobyte or few dozen kilobyte memory requirement. (Software) emulator is needed so that those programs can be used. Using these almost no cost devices for entertainment and education would be great thing at third world countries. 1 micron manufacturing process makes possible very sophisticated processors to be made with almost no cost, only thing to worry is power consumption. Also optical components to make those 1000nm processor faster can be used, optical fibre core is 9 micron smallest standard, but 5 and 3 micron is also mentioned and firm Nufern makes 1,8 micron (1800nm) optical fibre mass production, and 1,3 and 1,55 micron is mentioned in “Tapered silicon optical fibres” and “Extruded single-mode index core fiber” 2005, so mass produced (plastic) optical fiber can be used as cheap optical connection together with roll printing to improve otherwise slow 1000nm processor performance. However license costs are much higher than manufacturing costs, so license that is granted free for these roll printed processors or then minimal price (0,01 dollars per chip), or without license at all (public domain or shareware and freeware processor licences) is needed. These roll printed processors will be mostly 20 year old designs anyway, and outdated because modern CPUs are made using 16nm process, 3500 times more area efficient. But roll printing can be made cheaply. GPUs, DSPs microcontrollers etc can be made cheaply. If efficiency must be improved, transputer (XMOS makes transputerlike microcontrollers), “systolic array” processors, “processor in memory” processors, VLIW-, CPU/GPU hybrid, old Coldfire processor/DSP (not just ARM or x86 processors), VIA is manufacturing x86 processor with low power and improved efficiency, roll printing it would perhaps make suitable 1000nm processor, and some exotic processor models can be used (if is any sense to use them, manycore/multicore and other exotic processors that small niche manufacturers manufacture use non-standard operating systems mostly, some manycore processor manufacturers, 64 -100 cores or more, use ARM cores, other use their own RISC designs that are non-standard). But efficiency is not perhaps the main point but cost, how cheap (or expensive) these roll printed electronics are. Cheap hand held PDA must be super cheap. These electronic products are perhaps for sale (or distributed free of cost by aid organisations etc.) only in development countries, not western countries at all, and specially aimed at third world market, roll printed electronics makes cheap products possible. Hitachi Super H or J Core is public domain core that uses ARM microcontroller code, other free cores are avialable (but is there programs and other software for them?). Enough programs, games etc. is needed so if old ARM programs are needeed only Symbian has those, x86 processor can use old Linux programs and abondonware from 1990s etc. Programs need to be freeware, public domain, shareware or abondonware also, or granted license that is free of cost for these almost no cost PDA devices. Memristors are coming (2018) to computers, so perhaps memristors can be roll printed also and increase efficiency of 1000nm slow processors. 8 bit game consoles are already made in only few dollar price at third world market in china, roll printed versions of them would be almost no price at all. Also utility electronics like health care and agriculture / food production can benefit from roll printed electronics. Power consumption of 1000nm electronics is thing to worry, but because those are slow electronics power consumption can be handled. Actually power consumptieon restricts powerful roll printed chips to servers or perhaps “home servers” can be used in private homes with electricity, acceleretor cards for cheap (printed electronics) PCs (these “accelerator cards” would be very slow comnpared to silicon chip, but they are used in printed electronics PCs that are slow also, if some other than ARM or x86 architechture makes possible fast operation, it is faster than ARM or x86 architechture processor, but can not be programmed like ARM or x86 processor, so it is limited to graphics accelerator card etc. duties) and cheap (printed electronics processor) tabletop PCs themselves. But electric power consumption makes futile the idea of cheap PC computer chip, altough processor is almost free of cost power consumption that user must pay makes the whole idea of almost free PC nonfunctional (or solar panels etc. must be large so that electric power requirement is filled). So perhaps roll printed CPU and GPU processors, DSPs, microcontrollers etc. are only used in mobile solar panel charged or otherwise charged devices where user can get electric power without paying for it, or otherwise small amount of electricity consuming devices. These devices can be given away for free, they are so cheap, paid by commercial sponsors or aid organisations. In india and china already exists PDA type children tablet PCs, no internet connection in them only internal programs and memory card slots. This educational / entertainment hand held “phone” (it is actually PDA without internet / radio frequency connection or any other connection than cheapest possible “memory card”) can be made almost no cost (if about 0,05 dollar is manufacturing price), but it will be useful for people who have no money to pay, and in areas where internet connection is not possible. In every village (or in every town if not in every village) can be “information loading station” where news etc. can be loaded by plugging memory card slot directly to another device (physical contact between devices is only way to share and load information, or use memory cards). PragmatIC is partially owned by ARM holdings, so cheap ARM licences should be possible. Even more cheaper would be 5 - 10 micron printed electronics, manufactured with inkjet printer with conductive inks or using almost standard book printing machinery. Because books are printed in third world countries also, same machinery that is used to print books there can be used to print electronics. 5-10 micron or more will make very slow processor. If 16 nanometer is current trend in silicon chips perhaps 16 micrometer is suitable for ultra-cheap printed electronics, manufactured at third world countries with book printing machinery or printed directly using inkjet printer. Perhaps ARM M0+ is suitable for large diameter process, it has less than 50 000 transistors. Other microcontroller - minimal transistor count but effective processors can be used, and microcontroller designs based on old 486 or 586 (Pentium) processors or 68000 (used in old Apple etc). Mass produced optical plastic fibre manufactured at 1,25 - 1,8 micron can be used to improve efficiency of long electric connections, if long connections are optical not electric. Displays (black and white perhaps, like electric ink), batteries, touch keyboards (not touchscreens) etc. can be manufactured with even primitive printed electronics. 1 micron (1000 nm) is needed to effective printed electronics processors that resemble late 1990s ARM or x86 PC processor models. Old processor had sometimes better than now standard x86 or ARM performance, like old Cray computer processors from 1980s/1990s that had floating point unit that was fast and using own Cray FP format but it was sometimes possible to get wrong results with FPU, or MIPS R18000 or R20000 processors that had different floating point unit also (but using standard IEEE), Apollo Computer PRISM was another old but effective processor. If manufacturing of them roll printed at 1 micron makes any sense, if they are more efficient than usual x86 or ARM processors, and if they have any usable software for general purpose PC. Or use modern design that is not x86 or ARM but more effective per transistor count, using it for special duties processor only perhaps if there is not enough software for it as regular PC. “Simplified floating point division and square root” Viitanen, “Multi-functioning floating-point MAF design with dot product support” Gök 2007, unum concept, “Hybrid hardware/software floating-point implementations for optimized area and throughput tradeoffs” 2017, and “Hardware-based floating-point design flow” 2011 (Parker) Altera FPGA are floating point efficiency improvements. In quinaplus.com netpage is “Qflop: an ARM cortex M0 floating -point library” that uses only 436 bytes so it can be inside cache memory of processor etc., and “Gal s accuracy tables methods revisited” 2004/5 is table lookup floating point method that is efective. Making optical computer using stacked mass produced plastic optical fibres at 1,25 - 1,8 micron will make very fast computer but very different of computers today, because no optical transistor or optical computer memory has been made. Roll printing plastic optical fiber to optical processor circuits is perhaps possible. TTA (transport triggered architecture), Dataflow processor, Synthesis kernel (Massalin) and asynchronous processors like ARM Amulet, Lisp machines from the 1980s (Texas Instruments), or lambda calculus direcly on the hardware like “Introducung the PilGRIM: a processor…”, and unikernel (Mirage), RAM machine, TRON / BTRON processor from 1990s, Unicore, or “NISD: a framework for automatic narrow instruction set” are other exotic methods. Not only building analog circuit logic signal processor or floating point unit or other ALU, but building whole analog computer using roll printing is perhaps possible. But there are no programs for them, so perhaps old Cray processor and Apollo PRISM based “microcontroller” designs can be made using roll printing, or use modern manycore microcontroller designs for roll printed products, like ePUMA, because only microcontrollers have such limited transistor count that roll printing is feasible. Modern manycore microcontroller design with most modern floating point ALU etc. can be made with roll printing. ARM and x86 designs however have programs that PC user could use, altough only earliest Symbian programs from early 2000s are available for slow ARM processors made with roll printing, 1000nm process makes such a slow processsor. How slow is modern VIA Nano processor at 1000nm roll printed, or latest ARM cortex A-55 processor if its transistor count is lowered removing some core memory transistors that processor can do without, and processor has couple million or copule dozen million transistors (10 million?). Because silicon memory is relatively cheap nowadays hybrid roll printing of ordinary silicon cache memory with roll printed other logic in processor is perhaps possible, making processor smaller and not much expensive than totally roll printed processor, silicon cache memory and roll printed parts are printed together to roll printed plastic surface. If mass produced optical fiber of 1,25 - 1,8 micron is possible to use, that can be used too, roll printed cheaply, even for making totally optical analogue or digital computer, but that is totally different from computers today. Also processor-in-memory designs like Venray Technologies and Micron Automata processor are possible to made cheaply, because the price of magnetic memory is low, 128gb “flash project price” is 4,8 dollars at dramexchange.com, so 1 gb costs 0,375 dollars. Because these PIM designs are using cheap magnetic memory as processor element instead of expensive CPU transistors, together with memory at least in some designs, using memory circuit cheap transistors (some PIM designs) as CPU processor that is 12 times faster than similar ordinary CPU in massively parallel tasks, cheap processor in memory computer made using 1 gb logic memory gates costs only 0,375 dollar using cheap and slow magnetic memory. Programming of these is different from PC s of today so software for them is needed, but cheap and reasonably fast PDA style device is possible to build at about the same price as roll printed CPU PDA, this another PDA uses silicon wafer made PIM chip as memory and processor and the rest is roll printed (display, battery, solar cell, touch keyboard, headphones). These two different (they require different software) PDA devices can also be used together so that they together are complete device so not displays etc. are needed to print twice for two devices if they have only one user. Also analog electric components such as analog signal processsors, GPUs, DSPs or floating point units can improve performance of otherwise slow 1000nm (or even 16 micron) electronic if roll printed instead of digital components. One way to improve slow processor is to use residue etc. number systems: “A residue number system reduced instruction set processor”, “A novel RNS-based SIMD RISC processor for digital signal processing”, “Direct residue-to-analog conversion scheme based on chinese remainder theorem” 2011, “Efficient converters for residue and quadratic residue number systems” 1993 Sturaitis. Inexact computing can also improve slow processor and decrease transistor count significantly, if processor is just designed so that program uses small snippets and when processing fails small snippet is rerun from memory (snippet is stored in memory until it is processed in CPU, when processing is complete another snippet takes is place in memory, if program snippet fails due to computing error it can be rerun again fast, not chrashing whole computer). Inkjet printers have 14400 dpi (dots per inch pixel) accuracy at least in Screen Jet 3100 and Epson Stylus, about 1,76 microns,and transitor can perhaps be 3,5 micron wide when inkjet printed in slightly modified inkjet printer. Book printing machinery can be 600 lpi (lines per inch) with 16 colour cells so accuracy is 9600 dpi, 2,65 microns, and some offset or gravure or flexigraph printing can reach 14 400 dpi. In third world countries electronics can be printed in place using inkjet printers and book printing machinery, price would be lower than using some western factory. But licensing cost of of almost no-cost chip is problem, chip should have very low license costor no license at all (Hitachi Super H series). Using asynchronous CPU like ARM AMULET would propably make chip faster, if not using 8-bit multicore or transputer etc. exotic solution. If 2540 dpi is 10 micron (10 X 10 micron dot) then 9600 dpi is about 1/4 or 5 X micron and 14400 dpi 1/6 or 4 X 4 micron dot. Also not only digital, but analogue electronics can be roll printed or inkjet printed, and they can be much larger, dozens or hundreads micron large process, and even square meter or more in size, like analog “configurable analog chip” FPAA (J. Hasler) that uses small amount of electricity and even square meter size chip is possible and can be folded to smaller size. High licence costs make cheap electronics for third world almost impossible, if manufacturing cost is below 0,01 dollar per chip but license much higher. Almost- no cost devices can be given away for free, paid by commercial sponsors and aid organisations in third world. Integrated chips does not need be licence free, but royalty payment free or almost payment free (0,01 dollar per chip payment?) so that they can be used in printed electronics in third world countries. Actually if manufacturing volumes are great licence of ordinary silicon chip about 1 dollars (Allwinner A33 SoC cost 4 dollars and Intel Atom 4-core CPU for tablet PC 5 dollars, couple a years ago, when they were new processors, so 1 dollar royalty payment for processor is realistic) if similar processor is manufactured using roll printing, it will be much slower and larger, and less useful, but manufactured at much larger quantities, so about 1 dollars for 10 000, 100 000 or million ordinary sislicon processors does bring same amount of royalty payments if using only 0,01 dollar payment per chip but manufacturing scale is million, 10 millions or 100 millions cheap but very slow roll printed same processors. So licence holder gets same amount of money as nowadays, altough processors are much slower and larger (hundreads or thousands of times perhaps if roll printed) and so less useful, but high volume manufacturing makes same amount of money as normal silicon chip licence/royalty payment. So 0,01 dollar royalty payment/ licence for roll printed electronics is realistic, concerning about thousand times or so less usefulness of roll printed chips. Profit margin/ royalty / licence payment can even be in par with chip size, hundread times larger roll printed chip than silicon version has only 1/100th license/profit price per chip, 1000 times larger 1/000th of ordinary silicon version etc. Large volume cheap roll printed production that is not possible with silicon wafer technology however brings about similar amount of money to license holder than typical silicon chip licence. However chips itself are very large and extremely slow compared to silicon chip version. Possible devices are personal digital assistant type, several different designs all about 0,05 dollar cost, third world market only, made 1: either western factory roll printed, (hybrid printing of silicon memory with other components and optical fibre components is possible, also analog roll printed electronic, memristors, even analog optical computer roll printed using mass produced optical fibre) or 2: inkjet printed or book printing machine manufactured in third world (in India, Brazil, Indonesia or Egypt and Nigeria perhaps are book printing machinery for fine grain gravure, offset or flexograph printing, turning these machines to electronic circuit production. Printed displays, even black and white, such as TV sets, or analog radios, batteries, touch keyboards but not touchscreens, can be made with much smaller accuracy and much coarse roll printing machinery than PC processors, memory can be roll printed or cheapest silicon version available, silicon memory needs hybrid printing tech with roll printed components, CPU needs roll printing with best accuracy). Western roll printing has 1 micron accuracy (PragmatIC), inkjet and book printing machine 4 microns, perhaps 5-7 micron transistor is posible. These devices have no internet connection, other than direct physical contact to another device, no loudspeaker, only headphones, no display, only Google cardboard virtual glasses style most primitive video glasses black&white roll printed, simple touch keybord, solar panel brings power, cheapest possible “memory card” can be used in some devices. All contact surfaces are roll printed flat connectors, not round connector jacks for memory card or headphone, video glasses etc. Different processors and operating systems 1: Linux and Windows (old, 20 years old?, Windows Mobile /CE? For free like Android), processor old Pentium / new Atom or Quark, or other x86 but not Intel, or other Windows compatible (Transmeta Efficeon, Elbrus, Kalray, Loongson, Mill processor). 2: ARM (old or new design), only old Symbian work in slow processor, Linux and Android perhaps but needs optimization for slow speed. 3: Processor-in-memory cheap silicon chip (Venray, Micron Automata), cheap and fast, perhaps made using cheap maskROM, but needs own operating system, same price, about 0,05 dollar per device, altough CPU and memory made using silicon wafer 4:Other (GreenArrays, Rex Computing REX 256, Knupath Lambda fabric, UPU Harmony CPU/GPU hybrid etc), needs own special OS. Speed needs optimizations so inexact computing (Rice university) should be used, 0,25% error rate in CPU and 8% error rate in GPU and signal procesing (computer graphics, audio, video, still images, 8% error propably makes bad audio quality but does not matter). Program must work altough small mistakes are inevitable (using error correction? non blocking data structures?). Asynchronous CPU or GPU is another possibility, but needs special OS so it is worser option than inexact computing, can be applied to Other than ARM or x86 or Windows compatible processors because they have different OS anyway, together with inexact computing. Device can have CPU + GPU combination where GPU is inexact and bigger than lesser inexact or non-inexact (standard) CPU, most transistors are in GPU not CPU, which is other way around than usual practice. Because several different 0,05 dollar or less costing devices can be made, video glasses and headphones are only visual / audio means, they can be changed from device to another so devices don t need loudspeaker or display. Some may lack battery, they must be connected to solar panel or another device s battery. Solar panel can also be one separate piece like headphones and video glasses, no solar panel is needed in every device. Second device gategory: internet receiver. These have analog and/or digital TV, analog radio (like chinese cellphones), radio frequency receiver for internet, but no transreceiver, so they cannot send information, only receive it from internet, like TV or radio. This is cheapest solution for no cost internet, they only can receive multicast internet information: internet radio and TV channels, and other internet multicast material. No subscription line payments or other line payments because they are only receiving devices. Near Video On Demand NVOD is old multicast technique, that can be used in internet also, for example Wikipedia has 5,5 million pages, if 0,01 second per page (no pictures, only compressed text) is used in multicast channel about 12 hours is time when all pages have been send. If user search Wikipedia interenet receiver has given information (page index) when page searched has its 0,01 second time slot in 12 hour time, device automatically downloads it when right page index mark has been received, in 12 hour time period (0-12 hours, avarage time is 6 hours to be waited). Several channels can be used in multicast transmission to speed up process, like NVOD. Multicast internet sends same content in same radio frequency to all internet users, all receive the same channel, but cannot respond. One frequency channel can send information to millions of devices. Several hundreads or thousands multicast radio, TV, and textual / graphical information channels can be on air at the same time. Data compression can be used. Internet receivers can be sold not given away, using cheap 90nm indian new silicon chip production plants for example, so not roll printed processors altough display, keyboard, battery, keyboard, solar panel can be roll printed. These have colour display, and internal loudspeaker and memory card slot for small, slow and cheap memory card. CPU perhaps 90nm manufactured in India? Or Chinese modern model.
