Geothermal and Tidal are in the same category -- niche energy that works for very specific locations on the planet. The strategy should be deploy solar - deploy nuclear.

Put some research dollars towards deep geothermal and piggy back on O&G research but don't distract from the needed current strategy.

If we can get drilling tech improved, we could drill far deeper and geothermal would be viable anywhere on the planet.

Well that and then the deeper you drill, the more you will need to pump. There are significant complications. On paper I agree - pragmatically it still seems far away when we have great options already available: I mean alternatively we could use the power of the Sun (technology we have already developed). We could also use uranium and plutonium to power long lived electricity. Convert that electricity to heat via heat pumps (already available tech).

All for improving drilling tech -- maybe let O&G bare most of the cost of research though if we need to compete for research dollars.
