Ok, but that still doesn't answer my question of what specifically SpaceX did differently. For instance, you said bigger temperatures are needed and that is limited by existing materials. So did SpaceX invent materials that could stand a higher temperature?

Does anyone know what SpaceX did special in designing and building the Raptor that allows it to reach such a high pressure?

Top-level ev's like the Model 3 are already superior for most drivers. The only problem is cost, and that is being fixed in the coming years through steadily falling battery prices.

Other use cases like aviation and ocean boats are more difficult. It may well be that synfuels made with renewable energy will be the solution there.

I guess you could make a case that, today, SLS is further along. But SpaceX is moving several times faster here than SLS, so in any case it is going to be up and flying regularly long before SLS. And in terms of cost per weight to orbit, it will be a hundred times less.

So it looks like I was mistaken.

The effect of national policies vary according to region.

But let me ask, what do you think causes homelessness?

That was one line of thought that lead to the rejection of the Enlightenment view of the powers of human reason, but there were others.

Here's some historical background. In the 19th century the West enjoyed an extraordinary period of peace, prosperity, and technological progress, all under the guidance of Enlightenment philosophy, with its focus on the supposedly unlimited powers of human reason, and Liberal political philosophy.

But then there was what we now call World War I, which was remarkably destructive and killed of much of an entire generation of young men. And that in turn lead to the Communist revolution in Russia, and great political instability in Germany, which had been seen as the most civilized of nations, which lead to the rise of the Nazis, and also the Fascist regime in Italy. In addition modern developments such as radio and the automobile produced considerably cultural disruption.

All this produced great confusion and despair among much of the intellectual class, and a great many abandoned Liberalism and Enlightenment philosophy. The book in question discusses three philosophers who searched for alternatives, and one who stuck with the Enlightenment.

He never stopped thinking about philosophical problems, and when he returned to academia his views had changed radically.

I brought in conservatism because homeless is in part due to national level policies. Conservatives and liberals agree on that.

The article presents the expert case for why hyperloop is doomed to fail. Normally in this sort of situation, I assume the experts are correct, but not in this case. Let me explain why.

The reason is that we have been in this situation several times before with a Musk idea. The experts all said it was completely crazy, but nonetheless it succeeded spectacularly.

The reason the ideas succeeded is Musk is a genius and as a consequence he thinks things out much better than the experts, who are not geniuses, do.

I am not saying that hyperloop will succeed. No one succeeds all the time, and perhaps this time Musk will fail. I am just saying it seems to me virtually certain he is quite aware of all the factors that the experts say would cause hyperloop to succeed, and has developed surprising solutions to them, and there is a good chance these solutions will succeed.

Conservatives explain homelessness as due to liberalism. They say this works two ways.

In way, liberal values causes people to make poor life decisions that lead to them lose their jobs.

In the other way, liberal economic policies lead to a lack of jobs and also overly expensive housing.

Question: why is this called a supercapacitor, rather than just a standard one?

One of the reasons Musk is a genius is he can figure out these sorts of synergies.
