Comment Re:Can't reject waste heat with a laser (Score 1) 46

A quick and non-technical explanation of that, is summarized by the amount of drool pooling in your audience while you give a "non-technical" explanation.

You think there was a time when most people understood entropy? Or the mathematics needed to understand it? How quaint.

Comment Re: An endless supply of nuclear waste. (Score 1) 63

let the market decide, instead of being a political decision based on feelings. But that is unrealistic:-(

It's unrealistic because the market doesn't get to decide. Logic doesn't decide on the supply side OR the demand side. On the supply side, the market is controlled by regulations which were put into place because power companies proved they couldn't be trusted to function without them. On the demand side it's limited by physics, power has to get to places before it can be used.

In the USA for example power companies are really only able to profit from new generation projects, so they are motivated to produce the most wastefully expensive projects because when they cost more, they can pocket more of the costs. That means nuclear whether it makes sense or not. And while everyone complains about solar requiring grid improvements, so does nuclear. It represents a large amount of production in one place, so you need a large grid connection to that place. And they are typically not built near other things for obvious reasons, so there's no synergy.

And then of course there's the fact that it's already a requirement to pay the expected decommissioning costs up front, but it's never enough, so The People always wind up paying.

Or you could bury it at the bottom of an oceanic trench, where "given enough centuries" it will be subducted into Earth's mantle.

This has been studied and it's not that simple. First you have to get it there, then you have to ensure it doesn't break open and spread before it gets subducted. I had the same idea, it just turned out to not be a good one.

Comment Re:A plant that burns nonexistent hydrogen. (Score 1) 75

By grossly inefficient you mean twice as efficient as one of the most common ways we convert stored energy: burning gasoline in an otto cycle?

Irrelevant to the discussion at hand, where no otto cycle engines are involved.

Yes it is inefficient, around 40-50%. But it does have some benefits in that it actually scales quite well compared to say batteries.

It doesn't. That's why TCO on a HFCEV is far higher than a BEV.

Comment Re:EV sales in *USA* plummet (Score 1) 236

Jimny engines would have to pass emissions acceptance and then the vehicle would have to pass crash testing. It's difficult for a small vehicle to survive the partial offset crash test and we actually make light trucks do that here. Finally, as a light truck it would be subject to the chicken tax. It's three major hurdles to cross and then no, I don't think they would sell "like crazy" here, though they certainly would sell. But Suzuki left the US market already so they would also have to implement a dealer and spares network again, so that's a fourth impediment.

So no, it's not as simple as "regulations bad". Suzuki was already making the post-Samurai Jimny for other countries when they left the US auto market in 2012, and if they thought it would have been a contender, they no doubt would have stuck around.

Comment Re:What's happening to the US? (Score 0) 236

Having lived the last 50+ years knowing the US as the leading country in innovation and technological advancement, it truly astounds me how the situation seems to have completely reversed now.

What's happening is that the Republican plan for decades is being fulfilled. During the Reagan administration they began compromising education in order to produce low-information voters, the actual phrase was they were trying to eliminate the "educated proletariat" and they succeeded. Now enough Americans are dumber than dogshit for them to sell fascism as freedom. We've maintained our technological advantage until now by importing educated people from other countries, but now that we're abusing anyone who's not whiter than white, they don't want to come here as much and they're looking for other homes. Also, whether they want to come here or not, the goal is to get rid of the brown people.

And, paradoxically, this only worsens the US position in relation to China, the very scenario that the same people who reject clean energy fear so much.

Yes, but the people making the decisions are in their sunset years and can also afford to leave the country.

Grid scale batteries with nuclear would be ideal - the battery can absorb excess electricity allowing the reactor to run closer to the demand.

They'd be ideal for nuclear, sure. But if you're going to have the grid scale batteries, why use nuclear? Right now the reason is obvious, we don't have those batteries, so we can't just shut off plants. But the goal isn't to shut the plants down early, but rather to avoid building more of them.
