OK, I probably misremembered the different numbers from conversion, compression, transport, etc, but the overall figure was that generation to wheel efficiency was in the realm of 20%, while generation to wheel with batteries is more in th

I misremembered the actual value, but that doesn't change the overall point that the whole process from power generation to the wheel (in the case of vehicles) have a very poor efficiency, not significantly better than traditional dies

I don't know for other countries, but in France Enedis (in charge of the distribution network) indicated that the network can support no more than 6% of H2. IIRC higher proportions of H2 would actively deteriorate tubes and stuff (I do

Another of my unpopular opinions is that wind power is an abysmally bad capital investment with a terrible ROI (when not heavily subsidized) and even worse EROEI, and all that circus about H2 is a new way to meddle with the financial number

Sure, however basic physic won't change, and H2 will remain the less dense form of fuel (compared to any hydrocarbon). A group of aeronautical engineers calculated that long-haul flight planes running on H2 are impossible for energy de

My unpopular opinion is that H2 is an overall very poor solution to our current problems. It replies poorly to the electricity storage problem, because the production chain efficiency is really low, as low as 15-20% : electrolysis has a ~45

In a similar discussion yesterday ( https://news.ycombinator.com/item?id=24697860 ) many seem to pass easily over the basic fact that monopolies are wrong, whatever your political/economic leaning is. I commented: In eco

In economics, a well-functioning market is a market where no single actor can manipulate prices all by itself. That's why monopolies (oligopolies - monopsonies) are fundamentally bad. In some situations where a monopoly makes sense (th

In all cases monopolies are bad. If you see it from a socialist POV, a monopoly should only be public and democratically controlled; if you look at it from the capitalist/libertarian side, any actor who can manipulates a market by itse

Sure, but as I said "un filon" or "un bon filon" as meaning "easy money" is very common.

"Filon" means a mine vein (and is used figuratively as a source of easy money). So the name seems pretty good.

Big Tech is bringing us in an era of renewed feudalism. They can't be broken up too soon, or in too many pieces.

I was interested with computers since first contact in 1982. I had an MSX from 1985 on which I learned BASIC, then wrote my own assembler (because commercial ones were too expensive). Some years later, having busted in University, I was an

Weird to call it "Spanish". Catalan is also "Spanish" (though you'll find a very small number of speakers in Southern France). Usually Catalan is opposed to Castilian.

At some point in my company we've bought quite a lot of Intel SSD, and many failed after a relatively light use. We're using Samsung ones, and they're obviously much more reliable.

The H2 cycle is quite wasteful. The touted "climate friendly" H2 will supposedly come from electrolysis. But electrolysis is a very inefficient process (as much as 65% of the energy is lost in the process), that's why industr

Arguably as most Japan treasuries are owned by the Japanese themselves, and carry 0% interest, we can consider that the debt has already been repaid. That's apparently what Warren Buffet thinks.
