@PandaBear for a guy who works in Silicon Valley, you seem to be a skeptic. When I started in Semiconductors, 65nm was the most dense part of a chip. Now was are talking 5nm tech nodes... Now that's crazy talk!
The world says "I'll believe it when I see it."
Silicon Valley says, "I'll see it when I believe it."
I say, "Go big or go home." I decided to go big.
VC says "I'll sell it when I believe it". I don't disagree with a lot of the stuff here. Hey, I believe in EV (just a matter of when), solar (just a matter of where and how much), and self driving (just a matter of when and whether the road will evolve before the car or the car will evolve before the road).
I think the problem with some of the stuff shown here, is that they are interesting but not marketable as it is today. It may become valuable one day, like digital signal processing eventually did because of process node improvement.
Regarding to energy, if the patent office says perpetual energy machine is not patentable for obvious reason, I'd say they are right. If you can do free gravity manipulation you will get free energy, and to avoid violating this law of physics you have to insert / remove energy to manipulate gravity, and we have already done that.
I think I started my semiconductor work back when it was 130nm? and I think I had a few products still running in the fab today (or maybe obsoleted already, I don't know), and the thing about semiconductor is you never heard of the companies who died or got absorbed because of failure. It doesn't means nothing can be done, just whether they are ready today or not, and whether there are better solution already somewhere else.
Regarding to energy, I do believe EV is actually the solution of unstable solar and wind, you just have to be able to detach the battery from the car and charge the battery only when it is cheap, and have some spare lying around the house, or gas station, or office. That's the "go big" thinking I've been telling you guys.
If you have N+2 battery and the car need N, and you keep 2 to charge when it is cheap. You can rent them on road trip, bring them for camping, charge them when you are driving, charge more when there's free energy (because of duck curve, or on a windy day), etc. See, that's go big, but we are probably not ready yet (only NIO is really doing it).
You know what else? Poor people can afford EV, being cheaper than a gas car, if you can just swap battery, lease them, or use a bunch of older battery for long commute. Yes it is a workout and you lose some trunk space but you get a cheap commute.
