From Recent News
New Batteries created by bacteriophage:
I really do think it won't be too long before we have battery technology that is clean to make and clean to use, and requires no disposal. Two decades, though we've got to keep the R & D coming. Plenty of jobs to invest there -- get the kids in higher education for free, and make sure we've got housing, food and clothes for everybody.
Offshore wind farms which more than meet US energy needs:
While I think its high time we turn to renewable resources for energy production, I wonder why the big push for putting wind farms offshore? It seems they'd be a lot of work to set up, and then get the energy back to the mainland, even if only in relatively shallow water. Looking at this wind map (the multi-colored one on the left) and this one of South Dakota (with a legend explaining the colors), it appears there's a LOT of wind energy to be had in the middle of the country, though from the first map, it really does look like there's even more just offshore. All I know is that if there's wind there and we know it, it's a lot better than drilling for oil and not knowing how much is going to be there.
And astrophysics geeks talking about the science behind FTL warp drives:
The comment by Geckipede is a helpful explanation of what I was talking about in an earlier post.

"The problem is that in order to have a region of spacetime moving in relation to the outside universe, space has to expand behind it and contract in front, which demands negative and positive gravity in those regions. You need a large negative mass held in place in front of you, and a large positive mass behind." [Joel adds: All you have to do is carry around your own quasar and black hole, and you're set. But put the black hole at the front, and try and scale it back a bit so it doesn't actually tear a hole.]

So where can one pick up their own quasar and black hole? Seems like sort of a specialty item. I'd definitely want one with a good return policy and warranty.
