I went w/ Kobalt for drill and weedeater. regretting that now. Not due to performance but interchange since it is a Lowe's brand only. I think I'm going Dewalt in the future due to less vendor lockdown. Chainsaw's were Black and Decker 5 yrs old. Not as good. Homelite 3yrs old. better but brand doesn't seem to have staying power. I've cut 18+ diameter trees but it wasn't great. took a couple of charges. I haven't seen anything I would suggest for clearing land but I think the are good if you just have a couple of acres you are trying to mind.

You're right. But solid state batteries is much like cold fusion. How do you get charge to flow freely across solids? Hasn't ever been done. Any is possible. I have seen multiple claims that it has been achieved, but they have been scams.

I actually have seen the $/kwh curve through history. I think to get to cost parity the cost has to decrease by another 2-3 times. However there is no technology roadmap to make that happen. There was one for previous improvements. Basically increasing the Nickel content. There isn't much room left, and safety issues grow more and more. Current chemistry burns at 1400C and explodes with shrapnel like a grenade. Material development to protect passengers from this is ongoing. I should know I am doing it. But it is very costly. Very difficult for today's technology. It takes completely new material combinations. Increasing temperature and explosion force will make it impossible which is required to make the batteries cheaper.

I don't. Without subsidies this industry would be dead.
That roadmap is only obvious now in hindsight. 20 years ago people were saying the same thing. "this is the max. No way to make it better". This will likely be innovation rather than evolution but i think it will happen just like it has with almost every other technology.

About what though? Are you talking about computer chips? If so, you are referring to Moore's law, which doesn't apply to either photovoltaics or Li+ batteries. The roadmap according to Moore's law was pretty clear with computer chips.
You have to admit...there is a mild irony to a snow skiing event having to be postponed on account of *checks notes* snow.
I'm not saying that I know when or how it will spring forward. I'm just saying that almost every tech advancement has met with a crowd of folks saying it isn't possible and then lo and behold some wunderkind steps up and says "how about we stuff this peanut butter inside that chocolate" and voila.
Good for China. Why aren't we copying them?
Apparently we are but government regulations are slowing us down.
Two reactors at a site in Georgia. The two reactors in SC being built halted construction due to cost overruns. There was a reactor completed in TN a few years ago that was halted after 3 mile island. So 3 new reactors in last 5 years.
US government agencies make decisions on a decade time scale.
I can agree with all that except for the word "reduce". We need to improve the regulation environment so that we are focused on right things. I think this would have the impact of streamlining regulation, but when I hear "reduce" I think most people just mean less for cost reasons, even when the regulation has safety value. It makes some sense that these things take time. They are super big and early design flaws are hard to rectify later. They are also potentially devastating if done poorly. Our problem, like so many things in the US, is that we jump back and forth on public support so the programs are start/stop rather than steady progress and improvement.

No reduce it appropriate. There are so many unimportant ones they don't help safety. They only stifle innovation. The only way to open that up is to give developers freedom. Thorium reactors are inherently safe. They are nothing like current reactors and at least 90% of the regulations wouldn't apply at all.
saw that Q4 2021 EV+Hybrids = 11.8% of car sales. With the new models coming online over the next two years i think this will be 20% of new sales by 2025. That will be about 650K cars. We're hitting critical mass for this tech and there will be momentum. The manufacturers are in large part "pot committed" as we say in the poker room. Several sedans have ranges that are 350+ mile range. for most drivers this means they could go a whole week of normal driving without having to recharge. Especially now in the age of partial WFH jobs. car sits in the garage every other day so no hurry to charge up. Cost is still an issue and subsidies need to be scaled back over the next decade but EV's are here to stay.

If the government removes subsidies the demand goes way down from 11.8%. Projections of demand going up requires the government to outlaw ICE cars. It is all about government force at this point. Some wealthy people will buy them because they are new and there are some handling advantages to them. But the vast majority of people won't be able to afford them or use them in all the ways people use cars.
If that's true then they deserve to die out. I don't think it will be true. I have no issue with the government trying to prime the pump for a while but eventually EV's do need to stand on their own. I think they will. I think that time is less than a decade away. Much of the EV performance is already better. They are a little challenged with distance and more challenged with price, but i think both of those get good enough over the next decade that ICE will lose even without subsidies.

I have seen no roadmaps for getting driving ranges and charging times to parity with ICE vehicles, and I work in this industry.
Urban driving for EVs can make sense. Daily commutes within 15-30 miles can work. However, I don't see any projections getting EVs to the point where you it makes sense to drive from long distances. It takes 45 minutes to charge up with the fastest chargers. Think about it. Today it takes 5 minutes to refill your tank. At best that would increase 9 times. If you could get charging times down to 5 minutes the other things probably are already in place. I will believe it when I see it.
