- bachbach 8y agoWe must go back to the future! Seems like a recurring theme. It's near a half century for the moon landings. Should revisit the concept of batteries too. I'm reading a book called This Victorian Life and am constantly impressed by lots of little innovations now forgotten. Two concepts I think we'll have to revisit: heliostats for indoor natural lighting and terrariums aka self contained biospheres for space/underground.
