Geothermal technology seems to be moving in the right direction. I'm not sure it helps anyone who doesn't live next to an extinct volcano, but what do I know? Apparently "hydroshearing" is quite different from the better-known fracking, but it's not completely clear to me why this might be. It'd be nice to see my tax dollars (the DoE is in for half) get some positive alternative energy results, but I'm not holding my breath.
