Revolving Door Generator

A couple of ladies designed an electric generator that captures the motion of revolving doors.

Our main campus is on a hill which is apparently three stories high. The escalator is used constantly for getting up to the main green from West Green. Older folks use it, too, to get from the parking lots up to the Main Green. The other route takes you along side a bunch of traffic chugging uphill across a bridge which is none too pleasant.

I recently saw a short announcement on TV about how some mineral in Oman converts carbon dioxide into a rock, so we'll have to start importing that. The resulting product looks like cave formations....

Thanks for commenting, Bill.

The other trend is the 26% of Americans who are "fully obese", which I believe is related.

 I see a trend. I walk past one new construction on a small lot with two elevators. The first structure towers three stories. BCA, BillJRoost
