I hope SpaceX does as you say and starts sending a lot of probes, but a lot really depends on the whims of Elon. There isn't really a strong business case for scattering probes around the solar system. Starlink makes money. Selling

Of course efficiency matters, because electrical energy is a bottleneck resource. Renewables may be cheap, but they aren't free and we have a lot of other things we need that energy for. If you can make a car go 4 miles with 1kwh of

Continuing to burn fossil fuels forever isn't really an option. At some point we'll effectively run out, but before then we'll have caused catastrophic climate change due to our CO2 emissions. Synthetic or plant-based fuels

If disabling the engine weren't a requirement, my first thought would be to donate it to a local non-profit that, for some reason, owns a large WWII era tug boat. Its original steam engine was removed, so it's without propulsion.

This is cool, in part because it's similar to an idea I had awhile back but didn't know how to actually implement it. The way I imagined it working was one Voronoi cell per room, but with a tweak where the Voronoi cells are weight

Yeah, hand-soldering as the means of mass production of consumer electronics devices has (mostly) died out, but the people who actually build and test things, or the people who fix consumer electronics devices, still usually do a lot of sol

Why not? That seems plausible. It's about 214 horsepower, which isn't a lot but compared to most EV conversions it's pretty decent. The battery might be the limiting factor anyways.

The article makes it sound like a sort of special deal, but Intel does run a foundry service now, so in theory that means that they aren't picking and choosing who their customers are -- anyone with money can buy manufacturing capacity

There's also the situation that if a household's finances are tight, they can often rectify the situation by not spending money on things that aren't essential. If a government imposes austerity measures during a recession, i

As others have said, the article kind of exaggerated the situation -- EV conversions tend to use a lot of fairly standard parts. However, how those parts all fit together varies from one vehicle to another, and there's usually at leas

Several reasons: because AC charging is what people will generally have at their house, so if you only have one charging system that's the one you'd probably go with. Because there are several pretty good AC charging system that

The density of diamond is about 3.5 g/cm^3. The Earth's moon has a density of around 3.3 g/cm^3, so if you replaced it with a diamond of about the same size, it actually wouldn't be all that different in terms of gravit

Competition is usually good for bringing prices down (basically discouraging price-gouging by the manufacturer), but scale in itself can bring costs down too. The manufacturer has to amortize their development and regulatory approval costs

A fair point. You could have two simultaneous code paths access the same hardware device, if such were not protected by a lock or some form of exclusive access to some associated data structure.

Well, it's sort of the simplest explanation to think that when we die, our consciousness ceases to exist. This or any other hypothesis are un-testable -- at least, they can't be tested without dying, which is sort of a problem.

They had a very brief time window when they had a 60-vote super-majority though. Al Franken wasn't seated for months, and then Ted Kennedy died. Scott Brown won the special election. Harry Reid opposed filibuster reform at the time,

It is, but in just intonation it's harder to get away with certain things when the math doesn't quite work out.

If you think of a dominant 7th chord as four notes in a 4:5:6:7 resonance, then it seems the 7/5 interval is the "correct" tritone in this context. But a proper tritone substitution means turning the 7/5 into a 10/
