Except the notion of patenting genes that infect natural seeds farmers must plant for next year's crop. If the courts cannot see the distinction between farmers and plants violating patents, then the Congress may amend the law to oblig

There are lots of exciting battery chemistries, and some boring ones. It is impossible to say which ones will win out, in the end. The one thing certain is that whichever wins will have the best performance per unit cost, and thus better th

(As you pointed out before, elemental liquid Li or Pb would interfere with magnetic containment. LiH is an example of a diamagnetic Li-rich material resistant to radioactivation (other than the desired 3H). We need a great deal of Li in the

We mostly already have the combined-cycle gas turbines, and are burning NG on them, so their capital cost is already sunk. Until enough renewable generation is built out, it will be silly to build storage, so the turbines will continue burn

"Grossly extreme cost" refers to what any actual fusion plant would cost to build and operate. ITER, even at tens of $Bs, is small potatoes compared to what a real plant would have to cost.

Allow me to invite you to look up steam turbine overhaul cost and frequency. Do mothballed turbines need frequent overhauls? Or will they need overhauls after N hours' use at intensity Y, or after M > N operated at intensity X <

Literally every single person on Earth who even knows what renewables are knows they are intermittent. No one imagines solar panels produce peak power all the time, or any power at night.

Solar fusion doesn't produce neutrons hot or otherwise. It produces gamma rays, helium nuclei, and neutrinos.

Turbines cost less to operate part-time than full-time. One operated 4 hours / day, or one day / week, costs a lot less than one run continuously.

There is no record of electrical car promoters systematically lying about their costs. Electric cars were not, in fact, a practical prospect until lithium battery technology improved radically. It was not the prospect of electric cars that

I used AirBnB a fair bit back in 2014, but not since. Never again. I don't see why this is even a topic for discussion. I don't log into Google either.

Breeder reactors are not used because refining the bred fuel costs more than processing mined uranium. The overarching requirement on fusion neutron absorption material, besides delivery of heat to process steam, is that it needs to produce

Pumped hydro is very far from the only alternative to batteries. But you have been told that before, too.

Lithium hydride is like a ceramic, i.e. a high-melting-point solid. But whatever you use, you have to get extremely low concentration tritium out, somehow, to run the reactor on tomorrow.

We have many decades' experience with fission projects. The most reliable prediction, historically, has been that they were lying about costs. No fission project has ever been gone forward without massive public subsidy. There are no p

You do not seem to grasp the gravity of the current climate crisis. Fooling with fusion now is like trying to call a car dealer at midnight in a storm when you have crashed your car into a tree.

These are all different physicists. The ones doing other things are competing for the money being spent on the fusion projects instead. I would rather the other ones get it, because maybe something of value might come from that. That said,

(Lithium hydride, not hydroxide.) Other neutron absorbers are contemplated, but extracting tritium from them on PPB concentration is no easier.

The economics of renewables are the simplest and most transparent ever seen in power generation.

It is correct that batteries are the most expensive storage. One corrolary is that other storage is cheaper. Another is that other methods will be used instead. Storage is an integral part of a renewable-powered grid. It is figured into all

Fission doesn't have a thousand tons of lithium hydride just itching to explode in flames and gas the surroundings with that much drain opener.

Not to defend SLS, but it anyway has an escape tower STS lacked.

If more CO2 were balanced by more plant growth, CO2 concentration would not be shooting up, decade after decade. But it is.

It is still not too smart to run your heat pump below 10F. It will work, but the BTUs it can produce will be limited, right when you need a lot more because it's f*%&in' cold out.

As you have noted elsewhere, molten lithium would interfere with magnetic containment. Lithium hydride melts at a rather higher temperature. I don't know how reactive molten LiH would be with pipes. I know letting any air into contact

Hint 1: nobody is working on fusion as it happens in the sun. Hint 2: the sun already works. Solar panels already work, and are cheap and getting cheaper. Hint 3: ITER is not a power plant. It is not even planned to ever produce so much a
