If you are an animal like me, you might have already figured out that your most convenient source of electricity is your own body! Nature is a clever one, as she equips us with precisely what we need to do nearly everything we want to do in life, using our own awesomely powerful muscles and bones.
Humans are electric! Were absolutely full of energy, and when we direct our research to finding more ways to use our own personal energy to do the things we want to do, we'll discover how much more sustainable it is to be our own power plants (or more appropriately, power animals
If the Egyptians can build the pyramids with nothing more than animal power, then imagine what wonders of the world we modern humans, with far more scientific understanding of how things work, can accomplish under our own power
. (And knowing what we know about human motivation for creativity and fun, we can probably accomplish these amazing things using volunteers who are looking for adventures and a games and status, rather than using slaves.)
The most efficient form of transportation
is the bicycle, as it combines human power with a lightweight system to reduce friction and to allow for regulating the speed/power ratio with gearing to adapt to going up hills and carrying heavy loads.
For example, we can create efficient mobile homes, for the nomads of the world, using just a bicycle, a bike trailer, and a tent
Or we can use stationary bicycles, either with generators and batteries, or directly, to power everything from computers
, to blenders
, to everything in the average upper middle class British family's house
(though this last one isn't terribly practical, as you can imagine!).
So, next time you have something you want to do, maybe you can consider how you could do it more easily using your own body's electricity to make it happen, either on your own, or with the help of some technology!
Heck, I even imagine that with enough scientific understanding, we'll probably some day figure out how to travel to other planets and solar systems using our own human power...
