This is pretty much the infrastructural stuff that comes along with large quantities of energy. Whichever technology we are looking at has serious hazardous issues.

If all of your electricity in your lifetime came from nuclear [energy], the waste from that lifetime of electricity would go in a Coke can.

One advantage of a solar collector in space: It would be some kind of origami thing that would unfold and be relatively light because it doesn't have gravity to deal with.

The main problem with solar on the Earth's surface is that it is so intermittent, and we don't have decent storage yet.

The urgent finds you; you have to find the important. Importance is not fast. It is slow. It is not superficial. It is deep. And as a result, it's extremely powerful. When important matters go wrong, they undermine everything. When they go right, they sustain everything.

Programming (or making music) at night is dreamtime, a period exclusively mental, utterly absorbed, sustained and timeless, placeless, disembodied.

[Wind energy] takes a very large footprint on the land, five to 10 times what you'd use for nuclear, and typically to get one gigawatt of electricity is on the order of 250 square miles of wind farm.
