I am betting compatibility with past practice wins over incremental efficiency. But I have no way to evaluate whether retrofitting existing airframes with underslung tankage will be practical.

There is no natural life cycle for an ISA. (I am looking at you, x86!) It is easiest to pretend there is such a thing, because we are socially attuned for that. But it is not a technical observation, but a sociological one. And, that was my

No. It is that it is not worse , and there is already a great deal of experience with it.

In other words, you don't understand it either. That is not surprising: you would need to learn something. That would involve work, so is understandably unpopular.

Batteries are the most expensive storage. The overwhelming majority of storage will not be batteries. Of what is batteries, the overwhelming majority will not be lithium. Lithium batteries are well adapted for cars and phones. Other qualiti

Each dollar diverted to this from building out renewables brings climate disaster, global civilization collapse, and billions starving, incrementally nearer.

If they can unload those turkeys, good for them, bad for whoever gets taken in. If they can't, they are no worse off than today.

Not noticeably. The longer it takes, the longer the money flows. The moment its real prospects become clear to everybody, the money stops.

ITER if ever finished will have exactly zero apparatus to extract useful power. They are not even talking about starting on a power plant before 2050, or finishing before 2070. It will of course all be dropped long before then, one way

That is why it has this unholy fascination, and distracts attention from things that actually work here and now. It is pernicious that way.

It is moot: none will be built, because it would cost far, far more than other clean power sources already being built out. By the time this could be made to work, nobody will want it at any price.

It is moot: it would cost far, far more than other power generation methods, so will never be built.

This trivial observation, always trotted out, is always meant just to distract. Trolling, really.

None. Hot neutrons are the lowest-grade sort of energy.

The fusion they are working on emits hot neutrons. It will never produce so much as one kWh of commercial power.

It won't happen at all, because it would be astronomically expensive, way more than fission, and fission is already not competitive. So it is all castles in the sky.

Intermittency means you need storage too. So, you build out storage too. The observation is vacuous. A renewable grid includes storage. Storage is cheap and getting cheaper.

Most storage won't be batteries.

> The burden of proof is on you. It is, in fact, not. And, you are no reliable judge of it. Your assessment will have exactly zero effect on how the transition to renewables plays out. Either we transition to renewables fast enough, or

It would take far more energy to extract the 3He from the moon's crust than you could get fusing it.

Helion might conceivably make something useful someday. The others will just spend investors' money until it dries up. Helion too, most likely.

In kWh per dollar invested, solar panels are the most efficient generation technology ever fielded.

by ncmncm 4y ago
No, it wouldn't. The sun dumps untold petawatts of heat on us 24/7. We will never produce anything as much as the difference from one week to the next. In any case this stuff will never produce so much as one solitary kWh of comme

People are always imagining they have "debunked" Myers-Briggs. All they demonstrate is that they didn't understand what it's for. What it's good for is to help you understand how people who think differently than yo

If you built a solar farm last year, build another today, and another one next year, the cost for those will be seen on a sharp downslope. There would be no need ever to pay spot market price: you operate when you have power to operate. You

The main problem with LH2 is that it won't fit in the wing tanks like kerosene. The tanks may be very light, because the pressure is low and the LH2 weighs nothing, but they will be big! Some bet LH2 aircraft will have a wholly new sha

Cost is still dominated by natural gas price. As solar and wind build-out saturates in coming decades, mined gas will become unable to compete with renewables and hot storage, most places.

If you are in orbit, why land on it at all? Surely there are construction materials and ice only light-minutes away and not so deep down a gravity well. God knows there is nothing else down there of any interest.
