Too bad it goes so slow...

I love this!

They just need to add working brake lights and turn signals!

The "Rims" are a nice touch!

That is really cool.

From reading the title, I thought this was going to be some sort of perpetual motion machine, with windmills stuck all over it or something.

This is much better.

Looks like fun. Slow, unaerodynamic fun! :)

Compact version of the Green Hummer:

It takes about 10 calories of fossil energy to produce one calorie of food energy, for the average western consumer.

So that's how the Super Cub won over the bicycle in that Egan piece.

So, that's to say that it's probably cheaper on an eco-level to throw away your bike and get a car?

A Super Cub, anyway...

For those of you who aren't "in the know".

The Math
 

Only if your car uses 1 HP to carry an average person, or 3 for a strong, motivated athlete, and you limit your trips to your bike range. Regular bike use where appropriate can also save huge amounts of energy associated with sedentary health care, and make it far easier to choose tasty, nutritious food without too many calories. There are also huge energy costs from manufacturing cars and building roads for them.
Nothing is zero-impact. Even farming organic food displaces nature, and usually reduces overall biomass.
