We know how to make MRI cheaper. Put it in a can. MRI suites are built with copper shielding in the walls, and the machines are really heavy, which creates huge capital costs. (Capex is a big problem for medicine.) There's an easy solu

This is a defense of glass, specifically, and not a class of architecture in general. And "traditional" architecture is not a properly descriptive term; it tells us where the architecture came from, not what it is. Architecture is

The Pinkerton incident involved WotC protecting a trade secret, generally the least controversial part of IP law. This was not a case of a mobbed up card vendor roughing up a competitor. People can reasonably object to the tactics used, but

The efficiency of most existing heat-driven refrigerator and heat-pump designs is kind of disappointing. This isn't a fundamental thermodynamic issue; the Carnot efficiency for a gas burner at 2000 C running a refrigerator offering a 4

I think you missed the point of the nuclear tangent. The point was that people might be reluctant to build out energy storage capacity before demand appears because of what happened last time. The difference is that climate change is more p

Renewable energy is expanding faster than ever. And it's hard for people to look at that and think we're moving too slowly. But we still are. That's the basic cultural disconnect. When nuclear power became a thing in the seve

Well, for one thing, the only existing Yb-176 production facilities are in Russia. That means demand for a domestic supply is pretty high right now. The other thing is that for a nuclear reactor, you need many kilograms of uranium. But for

High-temperature superconductor refers to the critical temperature at zero field. But the crucial field decreases sharply with temperature, so the superconducting phase appears concave on a T–B phase diagram. Therefore, in order to operate
