Originally posted by zeitghostI'm thinking of the 50ft x25ft x 10ft deep hole I saw on the Grand Designs programme... how much energy did it take to shift 400 odd tons of dirt & put it back again...
In pure physical terms (100% efficient, no losses, minimum) moving 40 metric tonnes (40,000 Kg) to a height of 2 meters takes (40,000 Kg * 10 m/s^2 * 2 m) = 800 KJ. Or enough energy to power a 1KW electric fire for 13 minutes. But in pure physical terms that energy could be recycled by putting it back in the hole!Comment

There was an Irish church being done up, where they dug out loads of earth to put down cables to provide the electricity geothermally.
It was nice, though.Comment

I say: why not marry safe science if you love it so much. In fact, why not invent a special safety door that won't hit you in the butt on the way out, because you are fired. - Cave JohnsonComment
