I would like to invent a power generator that would collect into an electric battery some of the energy produced while riding a bike. It would have to be extremely light-weight, easy to attach to the back tire, and aerodynamic. There are a couple of places to start with this idea.
Look closely at this image. This solution has a stationary bike.
The Pedal Power Generator is almost
what I'm envisioning. I would love to work with a student of in the next couple of weeks to build this and use my bike for it each day. I ride my bike to work each day (see below), and (right now) we could follow the directions on this site, PedalPowerGenerator.com
, which offers:
free videos and plans to make your own pedal power bicycle generator station. Good for powering up your television while watching your favorite show. (Or your radio, cell phone, blender, or laptop, or wheat grinder!)
This power generating system is also great for emergency survival backup generator power. Pedal Power is one of the more reliable and consistent forms of alternative energy because solar panels can get blown away in a storm and only work during the day, and wind turbines only spin when there is wind....
From this, you can see the parts that we would need to have. The trick would be to get an extra belt to come off of the back wheel, and this belt -- somehow -- would have to connect to a generator that (perhaps?) could be carried in the biker's backpack? There's plenty to work out here.
Other ideas might come from looking at how electricity gets generated in non-battery bike lights like these two different examples: Reelight SL100 Flashing Compact Generator Bicycle Headlight and Tai...

There are many other places for us to find information once we start this journey. Here are two: Pedal Generator Projects and Bike Generator. (But everything looks so heavy and stationary.)
I wonder when this idea will be practical, in that, I'll still be able to get enough speed on my bike AND be able to store electricity in a battery.
