I think the fact that unburning CO2 requires input of energy is a salient factor. You can get 12 g of carbon for 22.4 L of CO2. 1 L (liquid) of gasoline weighs about 750 g. So to get 1 L of gasoline you will need to process at least 63 L of

There is an N in that formula, though, so burning ammonia is going to result in nitrous/nictric oxide. NOx is also a greenhouse gas (indirectly, apparently), and the hazy brown component of smog. One of the oxides is laughing gas. On t

This sounds like what you might expect from a using a random process (genetic algorithms, simulated annealing) to solve the NP-complete problem. The randomness injects suboptimal routes like this, as well as more optimal ones, but the fitne

Ford is trading at 108% book value, GM at 75% of book, Mercedes is 80% of book, and Volkswagen is trading at 1/3rd of book value (!?), assuming Yahoo Finance's numbers are correct. In contrast, Tesla is at 976% of book value. I th

According to your quote, it was a 94% tax rate on income above $2.5 million (in today's money). I'd be ecstatic if I had an income of over $2.5 million and had to pay that tax! Although I wouldn't put much effort increasing m

I agree that dismissing large swaths of the Bible makes the whole thing pointless. But what if the Bible, especially the Old Testament, was never the modern-style historical catalog of events that Evangelicals assume it is? The most recent

It definitely is an American evangelical/fundamentalist thing. (Might also be elsewhere, I can't say) The history is that in the 1800s many seminaries, beginning with German seminaries, began teaching theology that differed from t

I think user interface research these days consists of A/B tests, not talking to actual users. At least, given how user-hostile so many products are these days.

It's too early to get scared yet, we don't have any idea what's going to happen. In my opinion, a recession is most likely, but could range from nothing much to serious recession. But then who knows what will happen with Ukr

His point is that even if the reactor is free , it’s not competitive because of everything required to convert the heat to electricity makes it more expensive. That part has nothing to do with regulation.

I think it is a great result, but at the risk of sounding negative, I just can't see how this is a big deal. It was touted as the first time we've seen fusion ignition and is therefore a proof-of-concept. But as far as I can tell,

It looks like that article mixes its units. "Profit margin" is usually taken as net profit margin, and 8.89% is a reasonable average. No business stays in business with a 9% operating margin. So then the article compares net profi
