there is a very simple physical reason hydrogen for personal transport is not feasible: electrolyzer to fuel cell efficiency is much lower than charging a battery. we simply don't …

that's all nice and true, but not at all relevant to the point of long term storage.

is that relevant? the premise of the article was "long term storage", and my comment aimed at putting that into perspective.

if that were the case, how do you explain this sentence? "The heat is then extracted and stored in “bricks” made of steel shot and quartzite for later use,"?. or did the source sim…

sorry to disappoint, but this article glosses over a pretty significant constraint that prevents this from being long-term storage at all: storing the thermal energy from the compr…

Aside from not delivering on the topic promised in the title, this article contains several inaccuracies and false claims that are unlikely to be accidental given the author is an …

China's economics on solar might also be a lot different, but given that it doesn't publish these numbers all we have to reason about are the US and maybe Europe. Btw, ask France a…

yes, solar and wind energy generation is intermittent, that's no surprise to anyone. but it is much much cheaper than nuclear energy.

Not OP, but you're wrong about cost. Nuclear is more than twice as expensive as photovoltaics [1], so it's not cheap at all. And that doesn't include dealing with risks like prolif…

Most of them work in the security industry and do: * malware analysis (how does this malware work, how can it be detected, can we somehow decrypt data affected by this ransomware, …

Usually the reason for this behaviour is that at least one of the parties is not interested in resolving any contentious points, but merely in "winning" the debate by focusing on a…

I'm not debunking nuclear, I'm simply stating that just because you have a hammer climate change doesn't magically become a nail. Nuclear is great, but for the reasons I mentioned …

> No you don't from your arguments. One can be a fan of something without trying to blindly apply it to areas where it doesn't make sense. > nuclear reactors designs from the 70s a…

You do realize that batteries are not the only method of energy storage? In fact, there are lots of better ways to store excess energy from renewables over longer periods of time, …

I am a fan of nuclear energy for various reasons, and it's obvious that the safety and waste problems can be solved with new technology like small modular reactors with inherently …

Great class, thanks for sharing the materials. Would you consider also making the code for the exercises available? I'm working through the slides but the exercises are hard to fol…
