I actually had this exact experience. Blank stares. It's very difficult to tactfully say: "It's really a coal car."

Along the lines of fascinating (but still possible) energy ideas, Peter Todd, a bitcoin developer, commented yesterday about transmitting solar power with bitcoin.

The concept revolves around harvesting solar power in space. This one is somewhat of a reach, but within reason, and we're working on it (https://en.wikipedia.org/wiki/Space-based_solar_power, https://en.wikipedia.org/wiki/Space_...nology_program).

Anyway, the idea is that you harvest the solar power in space, and you use that power to mine bitcoin on-location. Then, instead of transferring the harvested energy back to Earth, you just transfer the bitcoin.
