off the grid
Nasa had us over for a presentation (work). They said something interesting: a space station is potentially the most off-the-grid you can get. Since it costs $10,000 per pound to get anything up there, they have a huge incentive not to need to transport anything in or out. While space travel is enormously expensive, it also may provide lessons on how we can live on earth more lightly.
