Very negative review of the prospects for fusion energy, especially of the magnetic confinement (Tokamak) variety. Among other things it says that people talk about the "break even point," where a fusion reaction puts out as much energy as it takes in; we have yet to meet that threshold for longer than a microsecond, but if fusion is ever going to work the output has to be at least five times the input, since four-fifths is uncapturable.

Project Innerspace is a nonprofit that aims to create exponential growth in geothermal power by 2030. Geothermal backers are feeling increasingly bullish, due to new drilling technologies pioneered during the American fracking boom, and I am seeing promotional material everywhere. Big money is being invested, in particular by oil companies. Still not a lot of power generation, but compared to say, fusion, geothermal is real and may actually be poised for a boom. Which would be wonderful for all of us. (Project Innerspace web site, 15-minute CNBC video)

The problem with our gerontocracy, says Yuval Levin in the NY Times, is that people like Biden, Pelosi and Trump see America through the arc of their own lives – the stable, wholesome 50s, the exciting, turbulent 60s, the booming 80s. They fight over which decade we should go back to instead of how to move forward. I think he has a point, but I would say that young leaders are not taking over more decisively because they (Macron, Trudeau, Kamala Harris) have no new vision to offer. We keep refighting old battles (race, immigration, taxes, health care, gun control, conservation) because we don't know what else to do. Levin wants younger leaders, but without new ideas, what difference will fresh faces make? Honestly, how many new ideas have you heard in the past decade that you want to see implemented faster?
