German Wikipedia lists round-tip efficiencies of 30-38%, and 43–54% if you cogenerate heat. I've already linked a paper which makes promises of efficiencies of up to 80% using reverse fuel cells. Here's an older one that promises

Reverse fuel cells aren't magic, though. I agree that 80% seems rather ambitous...

Those numbers are outdated. Round-trip efficiencies of up to 80% have been claimed: https://www.sciencedirect.com/science/article/pii/S036054421... If that's legit and can be made cost-effective, the cas

Lots of German households and industries use natural gas for heating, hence we've got something like 400,000 km of pipeline as well as storage facilities sitting around. Instead of buying natural gas from Russia, we could fill them wit

How do you expect this to work: To get a gender imblance, only one of the sexes would have to suffer these adverse effects due to, say, nutrition. That would likely still be caused by social factors...

The German natural gas infrastructure can in fact store several hundreds of TWh.

Power-to-gas technology can possibly fill that niche.

Also note that construction of the plant started in 2007 (ie years before Fukushima and the subsequent decommissioning of some nuclear plants). It was supposed to go online in 2011, but there were legal as well as technical problems that le

He didn't actually make that claim, though. The mention of medical science suggests that he isn't opposed to any and all technological progress. I do agree that the phrasing of the question suggests a more skeptical opinion of tec

The decision about female leagues was made at a time when transsexuality wasn't socially acceptable and hence did not factor into it. My point is, there are options to explore besides an outright ban. For example, a trans woman that go

His views on the topic lack nuance. First, you need to determine that the presence of male-to-female trans athletes is indeed a significant problem in a given discipline. Then, we as a society have to decide whether or not we want to do som

And many physicists (including Einstein) have argued it's a bad idea to teach things this way.

Could you narrow that down? I tried, but there's a lot of material to go through. The stuff I did find was only tangentially related and not indicative of any changes in position, eg https://stallman.org/archives/2

Investigating which axioms of your theory can be weakened whithout affecting its predictions seems worthwhile to me even if it's useless from a practical perspective.
