Solar Powered Computers Planned for Rural India 184

Posted by samzenpus from the heliotropic-keyboards dept.
securitas writes "BBC Technology correspondent Ram Dutt Tripathi reports on India's Uttar Pradesh state where authorities plan to use solar energy to power computers in rural village schools. The cost to run the solar panels is anticipated to be £1,000 per school. According to the report, up to 80% of homes have no power and most government-run primary schools have no power at all. In 2003 the Uttar Pradesh state government bought '1,000 computers for selected primary schools in all 70 districts' with another 1000 to be purchased this year, 'but most of these will not work because there is no power available.' The project is similar to a solar-powered school computer lab on the Isle of Wight."

        That's why places like Indonesia had a strong cell phone culture long before it became as big in North America -- they didn't have a choice.
        It's SOOOO much easier to pop a microwave antenna and a cell tower on a pole somewhere and give everybody a cell phone than it is to run a wire to every house and end up with non-mobile service.

        The only reason why wireline phone service is (was) cheaper than cell phones is that the vast majority of the infrastructure has been in place and paid for for decades. As a (phone company manager) friend of mine once said, once you've paid for the overhead, the rest of the usage is almost pure profit".

        I can see similar effects taking place WRT 'off-grid' power production. If there's no grid to be off of, then it's a no-brainer.

When I was on vacation there, I saw numerous cell phone towers on top of buildings, kids, older people, taxi drivers, fishermen, etc all have cell phones.

        Except they don't just know how to use them with zero instruction. And the schools lack a curriculum for educating them in the use of the computers, or lack any practical applications of them.

        I saw this when I was volunteering at a local school about 18 months ago. We were getting donated PCs cleaned up and usable so that each classroom would have a computer. What did the teachers intend to do with them? "Oh we don't know yet, but we want the computers. We can use PowerPoint to put our lesson plans on the TV in the classroom, right?" The PCs that were already in the school that we were supplementing were all loaded with spyware, games, and other assorted crap that made the machines barely usable (or in some cases, unbootable entirely).

        I'm not expecting the school to have a specific use in mind - but at the very least, have some practical reason for laying out the time and money. You don't buy a car and then say "hmmm....now, what will I do with this thing?" - you identify a need for personal transportation, then purchase the device that helps you achieve that goal.

      If only things were that easy. You have to remember that building infrastructure is extremely capital intensive. You can only do that if you've got a good budget surplus, and that's something that the Indian government does not have because 1) low tax rate 2) poor tax enforcement quality 3) corruption. Further, very few Indian government officials are altruistic enough to care about development of rural areas [although that has changed significantly due to India's last election results]. I should note that corruption is also decreasing thanks to increasing education standards and knowledge amoung the poor. Also thanks to NGOs that work to address the issue. But there is a tonne more work to be done in that area.

      I think the main idea is to drive the demand for infrastructure by all means possible. You give these rural areas a look at computers, an idea of how they can help. You give the teachers in the rural ideas a view of the future. You let them inspire the children and the parents. The next thing you know, the infrastructure demands will increase and slowly but surely it'll get done.

      So yeah, first things first is fair enough. They're just trying a different approach to solve the problem. Drive rural demand up and these folk may just get there. You've got to remember things are not that simple when you don't have a spare billion dollars that you can throw at the problem.

    Getting the machines before the power infrastructure is in place is dumb, and NOT just for the obvious reason (having invested a lot of money into something that will take success with a second investment to become useful is always risky). It's dumb because having electricity in those isolated areas is useful for so many other things besides computers, it should have happened already.
    There's tons of medical equipment that requires at least a little power, there's basic emergency communications, and there's all the simpler school supplies that require electricity. If none of these things justified getting some power to these people, computers in the classroom doesn't either.
    We're not just talking relatively high powered systems (such as x-ray machines) that are the equivalent of entire desktop computer labs either. What about small centrifuges or cautery equipment for medicine? What about having enough radio for local government to report being hit by a bad storm or earthquake? What about a few lights to read by, so that school can be held indoors when it rains?
    There are no compact, low energy computer systems that are any more efficient than those devices, and there are even surpluses of many of those devices in storage where they have been replaced by newer gear. Just imagine all the old filmstrip projectors or drafting tables in various urban school systems closets being put to use out in the country instead of gathering dust.
    • just to tell you, most things in india are that way. My parents grew up in india and I have been there more times that I can actually count, and I have had many times where we don't have reliable power, there are beggars outside the front door on the street, and there is a computer in the household. Its the way it works, India is the country that seemed to miss out on the 20th century(a line taken from my dad).

      This is how india improves itself, massive poverty, massive infrastructure and road problems,

    Solar Power!? Let me guess, they're not using AMDs :D

    Seriously though, plug some pentium M's in there and you might be able to do the job fairly efficiently. That, and I've always wondered if you couldn't somehow recycle all that excess heat bled off by the chip itself. Kinda like the regenerative braking in cars in away...

    • Current desktop AMD chips draw less power than current desktop Intel chips.

      The Pentium M's might be a bit better on the juice, but that's alright - Via and Transmeta make chips that make the Pentium-M look like a power-hungry pig.

      Unless you're talking about heating a building or something with that stuff, you're messing with the Laws of Thermodynamics here. Stuff doesn't work that way.

  • Yet another solar power project that's converting the DC output to mains voltage AC and then back again.

    Wouldn't it be better just to charge up a big array of car batteries and then feed the power directly to the motherboards (after a bit of voltage conversion etc)? There's no need to use AC power unless you're transmitting it over long distances. Right Mr Tesla?

      The problem is that modern motherboards need more than generic DC power from an external source. The power requirements of modern motherboards are very severe for current and voltage regulation. This has resulted in the use of DC/DC converters that are tightly integrated into the motherboard design to meet the performance requirements. The performance requirements for a P4 power supply are insane. This means that the external DC power supply is mostly a source of bulk power that it converted to AC on the m
  • Marshall McLuhan foretold this coming in his book Guttenberg Galaxy; nations, electonic nations, tribalized by progressing technology. McLuhan argued quite eloquently that technologies were not simply inventions that people employ but more importantly, are the means by which people are re-invented. This can be truly amazing if they can pull this off and follow through.

    Solar panels are also used for general electricity supplies in the Cambodia Schools [cambodiaschools.com] project. There are currently about 250 such schools (funded by private charitable donations, with matching grants from the World Bank; computers are donated by Apple). There was a Slashdot story [slashdot.org] about these schools in January, and how they hook up to the Internet via motorbike.

    Giving children an education is fundamental to long-term economic development.

  • Considering that people in rural areas still use animal power for most things, why not this? I'm thinking maybe a few oxen used to drive a generator or somthing along those lines. Considering that the technology you can purchase for an hour of work in many rural places is small compared to the animals you can purchase, at what point does stuff like generators running on ethanol, animal power, energy that can be locally produced using local materials, etc. become practical.
