That's probably a factor. Another factor is that people don't think there is anything that can be done about the problem. Until recently I felt the same way, but *given* nanotube cables of only modest performance, I now think the energy and warming problems might have a solution.

If that happens on the hottest day in the summer in Phoenix, there will be really serious problems. Like 20,000 people dying in one day. > Apparently you think it will continue no matter how hot >it gets in Phoenix? Maybe, maybe not. The power stays on in even hotter places. The max rise people talk about is 9 degrees. On top of the current temperature, that's really awful, but not impossible to live with. About equal to moving to Blythe, not as bad as several places in Saudi Arabia. Two engineering realities. When they were in Riverside, Alcor could see the difference in LN2 consumption between winter and summer. It was about as predicted, rather small because the winter to summer ambient temperature difference was not very large compared to the difference between the average outside temperature and the temperature of LN2. I.e., 273 deg C plus/minus 20 deg C subtract 77 deg (all in K). Second, because we use air transportation to bring in patients, it is critical that the local airport not be closed for days due to snow or other weather problems. That rules out a lot of places.
