Overweight folks, beware the watt.
I am providing a concept for you that can accomplish several admirable goals all at the same time. If you're green-minded and spend your days telling people how we need to "save the planet," then you need to read this and put your butt where your mouth is...umm, sort of.
Convergence Tech Inc. is ready to provide you with complete plans for building a bicycle powered generator yourself
. This generator utilizes any bicycle that is in decent shape and can easily produce between 150 to 200 watts at 12 to 20 volts DC. Bikes with larger wheel diameters provide a better mechanical advantage than bikes with smaller wheels but Convergence Tech indicates that their concept has been employed using bicycles of various sizes and types, all with satisfactory results. When you're done creating electricity, you can easily disengage the bike and ride it to work or school.
Some typical low voltage appliances which could be served up pedal generated power would include laptop computers, portable televisions, radios, cell phone chargers and lamps. Convergence Tech indicates that you can power much larger appliances with this device and they invite your inquiries regarding suitable applications. One of the best parts of this whole scenario might be that if you can't build one yourself, Convergence Tech is in the business of building them for you. They also have the plug in power storage units available so you can use your home generated power by just plugging in your devices.
So here's the plan, change your house rules to require that your kids must generate their own electricity for powering non-essential appliances. If they want their cell phone powered up, they get on the bike. If they want to play video games, they get on the bike. If they want to write a blog about... oh wait a minute, that's me!
