locust
 
Bicycle commuting rocks. It's healthy, safe, fast, cheap and levitra online canada the only emission is what the generic cialis effective biker breathes out. But it does have it's problems. One is that bikes generally have a very awkward shape. If there is no bike rack, or if you want to go somewhere with your bike, you're reduced to lugging a very cumbersome package around with you.
 
Well what if there was a bike you could fit in your trunk, that was the size of a briefcase, or that you could take on the subway. That sure would be nice.
 
Thus, the concept of the folding bike. You might be surprised to learn that there are actually quite a lot of these guys out there. They range from the practical to the nonsensical and from frugal to near-car prices. And today, at EcoGeek, we're going to buy viagra pill show you the best of the folding bikes.
 
 

Pull-String Power

pullgeneratorRemember back when cars needed cranks. Yeah, that was a bad idea. But even today, lawn mowers need a jump start. But do they use a crank? Heck no they don't. Pull strings are a much more efficient way of generating power.

So why do we keep seeing crank radios and crank laptops and crank flashlights. Why aren't there any pull string appliances out there. Well, there was, for a while, a pull-string power source that was going to be part of low price cialis the One Laptop Per Child project. We're not sure if the pull-string technology is still part of  OPLC, but SquidLabs, who produced the cialis for sale original idea for the pull-string generator, has realized the potential and is going to be marketing it to, well, probably everyone.

One minute of pulling will give you 230 minutes of iPod shuffle time, one hour of lighting, 25 minutes of cell phone talking or 45 minutes of Nintendo DS. Now that's what I'm talkin' about! It may be a long time before we have solar panels packed onto phones, but a pocket sized pull-string generator that will save you from being stuck in the airport without your DS could only be a year away. Plus, you get a workout while you're doing it.

Pedal Powered Laptop

{youtube}pwm6sRSl4jk&eurl{/youtube}
 
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 http://seyonic.com/cialis-online-india 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 canadian pharmacy viagra prescription 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 viagra price in canada testing out a new system to generate power from the footsteps of hundreds of thousands of commuters passing through the gates on propecia 5mg online a daily basis.The company is hoping to be able to revistaneon.net 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.

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.
