There should be more of these.  This revolving door actually captures the kinetic energy generated when people pass through it and cause the doors to rotate.

We need more human powered inventions like this.  Just think about all of the energy that we generate and waste on a daily basis that could be used to power our homes!

Fortunately, someone already had the brilliant idea of doing just that in a California gym.

Of course, the next logical progression could be found here as well…
