Pedal Powered Laptop

Having a somewhat disturbing connection with my PC, I have often thought, "Wouldn't it be nice if I had to work out to work." For example, if my mouse weighed 50 lbs, I could probably be a champion arm wrestler in a month's time.

But, instead, I become softer for every minute I spend at this computer, and I spend a lot of minutes here. This YouTube video that I spotted at ecoIron shows a pretty impressive pedal power generating system. The beefy guy on the left does all the work, while the guy behind the camera, one can assume, put together the electronics for the system. They're using an ultracapacitor, it seems, to store and regulate the charge, and have a "watts up" power meter measuring the draw from the device. Zack, the pedaler, seems to have no problem keeping up the 20-30 watts it takes to power the IBM Thinkpad.

I would pay a lot of money for a desk chair that had a keyboard and mouse pad and pedals. The Pedal Chair: Stay fit, use renewable power, and strengthen the man-machine interface. No one was ever this ready for the apocalypse.

Pedestrian-Generated Power

japanese_commuters

A Japanese rail line is testing out a new system to generate power from the footsteps of hundreds of thousands of commuters passing through the gates on a daily basis.The company is hoping to be able to set up a system to capture this power anduse it to operate the turnstiles (wickets) and the displays.

The system is reportedly able to generate up to 100 milliwatts per second per person.  Not that much, until you multiply that by 700,000 people going throughthe station every day.

DIY Human-Powered Tic Tac Light

Oh Instructables, how you please me! Someone has put together an amazing tutorial on how to make your own shake light out of a ball point pen, a tic tac container, a refrigerator magnet, some wire, some cheap electronics, a switch and (if you want it to stay on while you're not shaking it) a rechargeable battery.

Not only is this made mostly out of trash, it's totally an self-sufficient and long-lasting flashlight. Hats off the all the MacGyvers of the world, this is an awesome project for any DIY minded EcoGeek.
 
 

Gerbil Wheel Elevator

Because, apparently, stairs are too easy, some Estonian designers have proposed these human-powered elevators.  It looks like a heck of a lot of fun, probably considerably more fun than stairs, and requires absolutely no electricity.  However, it doesn't look cheaper, easier or safer than stairs, so they probably won't be widely implemented. 

It's an interesting rethinking of the elevator nonetheless, and I love the accompanying drawing.  And the innovation itself might be enough for it to be implemented in interesting architectural spaces like outdoor gardens or art museums.

Portable Squeeze Charger

alladinEcoGeeks have firm handshakes.  Or, at least, they will once the get an AladdinPower handheld and operated generator.  Just squeeze the thing and the juice starts flowing.  It'll recharge anything up to the size of a portable DVD player.  You're not going to have much of an effect on a laptop computer, but anything else is fair game. 

The device comes with a built in high-powered light as well as a cigarette lighter-type connector.  So as long as you've got a car charger for your device, you'll never run out of batteries again!

I've never actually gotten my hands on one of these, so I don't have any idea how difficult it is to squeeze or how quickly it can charge a device.  But I do know that it'll set you back 60 bucks and could be the secret ingredient in any of a thousand awesome DIY projects.
