We should harness the power of tectonic plates using 'Groundmills' for energy

Groundmills. We harness the power of the Earth's tectonic plates... We just put a windmill that moves. It's a giant blade. And so whenever the fault lines shift, it pushes this huge blade that makes electricity for everybody.

A signature on an item technically turns it into an open-ended contract worth infinity

I have the answer for you. It's because whatever you sign, that technically becomes a contract at that point. So if I hand you a piece of paper with my signature on it, you could, after the fact, go and fill in a contract above my signature. So it's actually worth infinity.
