Power Scheme for OLPC Project Falling Into Place
robotrachel writes "According to Technology Review, the $100 laptop intended for children in the developing world will be powered in much the same way that you might start an outboard motor on a boat. The new power system will 'make the laptop much easier to power than it would be with a hand crank, in part, because the users will be able to operate the generator in a variety of ways, including holding the device (the size of two hockey pucks) in one hand and pulling the string with the other, or clamping the generator to a desk, attaching the string to one foot, and using leg power.'" There are plenty of sewing machine treadles in the world, too -- I hope someone can figure out a way to combine them with the new design.
The next generation of geek will have massive calfs and thighs instead of a single massive forearm

These machines are actually starting to sound like something some people in the US might even like. I can imagine sitting outside in some remote area, working as much as I like without even worrying about running out of batteries (and getting exercise at the same time).
What'd I'd really like to see is an inexpensive laptop which has a screen that's highly visible, even outdoors. I could get a lot of work done that way, and work on my tan at the same time. Does anyone know of any? I'd assume it'd work best with grayscale.
I am not sure if something like this is powerful enough or even cost-effective, but what about solar cell technology to power these laptops?
Was this even considered?

That sounds awesome. Literally, since they say it's much quieter than your usual hand-cranked generators. And 'generating 20 watts is comfortable, and it's possible to generate 10 watts for "as long as you want," the developers say."
Free energy and a little exercise in the process. I like it. Watch it cost $250 for just the generator in the US.
OLPC = One Leg PC?

Make the string the power coord and you could have a yo-yo.
Fun and power.
The best mechanical coupling design would have a open interface. A rotating bolt that can take the pullcord attachment, or a sewing machine pedal cam, or a bicycle tire clip, or a homemade windmill/waterwheel/goatwheel, or any mechanical rotation.
Then include in its desktop a link to a blog for new powerup inventions worldwide. Necessity is the mother of invention, and local materials the father. Give these kids a way to improve and share, and we'll all get the benefits of their unique insights. What better way to harness the power of global kids?

To anyone who objects, please note that this is a carbon-neutral technology and therefore won't contribute to global warming except for the hot air from 'activists.' The Free Market -- gotta love it!

Why not just attach the string to an electric motor? That way the legs/feet would be free to operate the rudder pedals.

You could use them to hunt for pirates! Arrrr me matey!
I'll probably be modded down for this...
Aha! At least the get-rich scheme is revealed... hook them on pull-string laptops and then sell them replacement strings when the string breaks... ingenious! My hat's off to you Nicholas Negroponte!!!
I can totally see this -- a cluster of laptops.. err.. kids.. cranking or pulling away, but no, they aren't powering their laptop... The electricity is instead routed to a high-speed fan that's blowing over the local overlord.

Well, maybe you can own one, but your only chance of getting one in the US is probably to sign the pledge to convince everyone it's a viable solution.
BUT, it had only one program that when you pulled the string you got responses like "The cow goes MOOO!" Long live the talking wheel!
I was assuming that you had to wrap a rope around the fly-wheel and pull, repeat, until the damn thing started(my outboard was a really, really old two and a half horse British thing. Damned if I can remember the name), and an electric starter kinda defeats the purpose, no? Now with the foot peddle idea mentioned there, I'm sort of worried that a bunch of slave kids will be used to power a beowulf cluster of these things, like they are doing with the looms now.
What?

"It's the height of ridiculousness to say for those 9 lines you get hundreds of millions."
Well you know the old saying about the man and the fish.
Sure you can give them food and water, but if you also try and get them computers to learn then they might be able to pull future generations out of poverty and improve the overall living conditions of everyone in the area.
These types of generators are great as you can use very simple wind-powered cyclic motion devices to power the generator. You could even use a tree branch that was moving in the wind. Saves having to pull the string yourself.

Aside from the reality that have of the time is night, enough solar cells to power this properly might well remove the concept of rugged, portable, laptop from the existing idea.
"It's the height of ridiculousness to say for those 9 lines you get hundreds of millions."
The laptops will have network capabilities. Didn't you read about them?
Whether or not there's Internet for these children doesn't matter anyways - there's no Internet without computers, and they need the computers before they can have Internet. Maybe later someone can give them Internet.

Does anyone out there have a connected PC hooked up performing some life-changing work, or are they just useless when connected to the wwworld?
When's the last time most people have done anything life-changing with a PC, with or without the Internet? Sometimes the Internet is detrimental, too - a lot of people spend entirely too much time online, and setting down a small schoolchild and letting him use the Internet all day isn't so good.
PCs don't need to be hooked to the Internet to be useful. There were useful programs and stuff before the Internet became mainstream.
And at least when the kids do get the Internet, they'll already know how to use a computer.

In World War II in the War in the Pacific, American planes were outfitted with a special emergency device. This was a hand crank generator coupled to a Morse Code transmiter on a spindle much like a music box. As you turned the crank it would power the trasnmiter and the spindle would key the correct di di di dah dah dah di di dit (SOS) and some other information so a search plane or ships with direction finding equipment could find you.
The slang name for this box was a "Gibson Girl".

After the power grid fails, these will be rolled out to allow people to work. Since there will be no internet connectivity, static Myspace.com pages will be included to keep teenagers from rioting.
Well, if you really want to be charitable, you could also go to http://www.heifer.org/ , and for $300 sponsor a llama, a trio of rabbits, hive of honey bees, and a flock of geese.
But then you wouldn't get the cool OLPC, that they aren't supposed to sell in the US commercially...
Why is it that people who troll this subject can't get it through their thick skulls that these laptops aren't intended for children who don't already have food, and water.
/. Go read about the OLPC project and look at the list of countries they are going to provide computers for. Then read about those countries if you don't know what their economies/lifestyles are like.
There's one of you every damn time this subject comes up on
I thought it was more like One Legged Alternative Power
What if the Hokey Pokey really is what it's all about?
Yeah, they tried asking a user who had never seen a computer before to type up a set of requirements, and make some simple OS choices. Those ingrates were totally unhelpful.

Sheesh!
The OLPC is first and foremost a teaching tool for children. It will replace paper textbooks and possibly, depending on how the touchscreen/trackpad design turns out, even notebooks and pens to some degree. So the device does not have to be complicated to use at all. I guess it will save money for the schools too, e-books are cheaper to print and distribute than paper books.
We have been discussing this kind of thing for a very long time where I work. According to the news, Americans are some of the most heavy in the world, and to narrow it down further, most of those heavy people are computer professionals. (http://www.obesity.org/subs/fastfacts/obesity_US. shtml) and (http://www.perspectives.com/forums/view_topic.php ?id=40450&forum_id=64&page=3)
We designed and built a very simple solution to this problem...
We took a stationary bicycle and attached a generator to the rear wheel...it is a small enough generator to provide for a laptop...12 v, 15 a...
Now, to get 8 hours of work done, we use a small battery (about an hour's worth of power) and you have to pedal for approx. 4 hours to get your 8 hours of power.
Next we will try an elliptical exercise machine, and maybe a treadmill...
Theoretically, this little generator could be hooked up to any kind of weight machine...
... for any computer, laptop, desktop, whatever,... is a hand-crank not to generate power but to marginally increase the voltage given to the CPU (or whatever exact component) to give the same effect as overclocking it. This would be SO satisfying (at those times I'm waiting and waiting and wishing LotusNotes would Hurry. The. F*ck. Up. and Launch! Awready!) to be able to put some muscle into a crank and actually make the machine run faster.
FYI - school children in NO country will be able to 'buy' these. Sponsors provide them, if children sell them (I guess at the nearest Kinko's express in Djibouti's badlands?); they go without until another round of upgrades or distribution. They are not expect to distribute any of these in the USA, but rather in more primitive developing nations without accessible libraries and schools connected to the grid.
wouldn't that have been a more appropriate/identifiable analogy than an Outboard Motor? Most people don't live on the water, you insensitive clod.
Why stick up for big business?
"imagine Beowulf of those"? Is slashdot going down the tubes?
They have WiFi and mesh capabilities, so you only need one net connection in a village and all laptops in the area will be able to access the one connection. I'm not saying it's going to work well, but they did at least think of this problem. :)
I'm pretty sure that there's a lot of computer users (including myself) who could really use the exercise. Hell, just hook up a treadle to an alternator, and run that to trickle charge a UPS, so if you stop pedaling, your computer switches to hibernate mode.
Just because you can mod me down, doesn't mean you're right. Shoes for industry!
I agree its not the computers but whats on the computers that matter.
..fraction munchers.. number munchers.. puzzletanks.. math blaster.. logo.. that was the stuff. No internet there.
My Apple ][ GS can still give some of those poor kids a hellva education with all the software i have for it. Thats what I learnt on
The idea of cranking some power into a laptop has had me following the OLPC project from the start. When out in the forest/mountain where you need power for a device like a laptop & sat-phone the product line gets extreamly narrow.
You need 2 methods to effectivly power your stuff.
Solar being the most obvious sence it powers life on this planet ~~
For solar you need a good inverter & good panels. Flexible panels make it much easier as you can get more panel per square inch to send to the inverter.
Here is a decent setup
The second would be for at night or in low light. Your gas or for lightweight & low sound.. crank, peddal or plain old electronic car lighter hook up. Whatever gets juice into uour batterys!
I heard a few fit hampsters could work nicely as a non-stop power supply.

What was once true, is no longer so
Yes, I have a small child. No, she hasn't watched it into oblivion yet (she's working on destroying "The Incredibles" at the moment).
Is it just my observation, or are there way too many stupid people in the world?
...consider an electric starter.
(sorry, just couldn't resist).
Is it just my observation, or are there way too many stupid people in the world?
If it is as small and low speed as it seems to be, a treadle isn't the only way to use it!
As a low speed generator, it could be used in a smaller windmill, too. And as the generating element in a micro hydroelectric system.
Has anyone found any details on this little unit? Squid labs doesn't yet appear to have any information on it.
And, since the OLPC unit is running linux, that means cross development onto something like the Atmel AVR, MicroChip PIC, or Zilog Z8 might be just a short step away. Since I know that the AVR has app notes for using their parts as low speed USB devices, this may mean that building out infrastructure in a developing nation may just have gotten much, much easier.
At least, that is my hope ...
This is progress?
But I still have to question how useful this will be in the overall scheme of improving conditions in the countries where it's targeted. While the laptops aren't intended for places where there's no running water or a lack of food, I'm not convinced that you can jump-start a country's development by skipping important steps like industrialization and infrastructure.
Understand, I'm not arguing that there's no point in doing this, I'm merely suggesting that 50,000 hand powered laptops might not be the most efficacious method for moving third world countries along on the path to development. Especially as these seem destined to wind up in the hands of children, for whom there will be little computer-related work once they reach adulthood. Unless we're training them to be $100 laptop technicians.
The project won't be a total loss of course (even if it fails it's stated goal) but I have to believe that there are better things that we could be doing with the time, effort, and money that's going into this project.

Free energy and a little exercise in the process.
I wouldn't say that a human powered generator is exactly free. Humans need substances called food and water. These substances are often scarce in the areas which this laptop will be used.
IMHO, this laptop project is a great idea. Food will keep you alive but education gives power. Both are needed in developing nations. Perhaps this project will help a student design an irrigation system which will increase the potential of a crop.
If these are destined for developing countries, how are you going to enforce the rules governing who gets the computers? It seems to me that it won't take long for the militaries/ militias/ guerrilas/ warlards etc. to realize that a laptop can be a real asset to the operations. Consider the following:
Early development was sponserd by the millitary
1. Modern computers are largely due to code-breakers, artillary table generators, etc. developed during WWII.
2. ARPA/DARPA developed the Internet.
3. Would we have an NSA without computers?
Ways computers could be used for military purposes in developed countries
1. Google Maps-gives terrain for planning manuvers
2. Email for organizing
3. Weapons/warfare research
4. Training (the US military uses video games for training)
5. Finances - (e.g. Nigerian scammers)
6. Logistics tracking
7. Intelligence gathering (CNN was a big asset to Saddam in the first gulf war)
And finally...
How many times have we seen foreign aid misused?
- N. Korea using food aid to feed its army
- Iraq's oil for food program
+ many other instances that don't make national news where the local fighters come in after an aid convoy and take everything that was just handed out.
Don't get me wrong. I am a big fan of the $100 laptops-it really is a case of "teach a man to fish". I fully expect at least some of them to help the kids and eventually to get in the hands of adults who make good use of them. Just be prepared for the backlash when yet another powerful tool is used in a the wrong way and remember that the good done with it outweighs weigh(s) the damage it can cause when used for evil.
science is a religion
He was task with removing the burden of men watering fields in a third world country.
He came up with the idea of having water bufallo's go up a moving conver belt making the belt move turning a electric generator. And when they reached the top do the same on the way down... Simple... Purs the effort on them.
Well the Water Bufallo's did not like it at all.... So the men started to shove them up the ramp! And at the top. It took even more men to shove them down the other side... Yep they were producing power for the electric pumps but it took more men and effort to do this than by irigating the fields the old way.
Gyro quickly left the country...
The Embasador said he was sorry it did not work and not giving something that would help. But the Village elder say. You are wrong. Its a find gift! It give something for the Bufallo's to scratch their sides against...
I experimented with taking a spare keyboard, mouse and monitor and hooking them onto an exercise bicycle so that I could work out while using my computer. The motion required to turn the pedals made it very difficult to use a mouse and read the screen. I wonder if a treadle might have similar issues.
I ended up using hotkeys to replace most of my mouse movements. I eventually went back to using the equipment for it's proper purpose: drying clothes.
I suspect that the motivation to keep learning might be a problem, without the feedback that comes from a teacher/student relationship...
