It already is due to energy being the biggest mining expense. Miners congregate around inexpensive sources of hydroelectric/wind/solar energy.

I think a good litmus test for whether a field of study should be classfied as philosophy or science, is whether or not experts within the field are able to achieve consensus. For economics being a strict science, there are a shocking numb

I used to work as a controls engineer. Sensor fusion and redundancy is one of the most basic concepts in controls, and yet it was totally absent from a system that was responsible for flying the aircraft. There is more redundancy built in

We should have applied the same policy of containment to China, that was used against the Soviet Union. But instead we let our greed get in the way, and now we've created an (arguably) evil superpower.

Tofacitinib is one that I am familiar with. I am sure there are many more. https://en.wikipedia.org/wiki/Tofacitinib Also, I think it's a valid question that doesn't deserve downvotes.

Look at many of the large/fast growing/cheap cities throughout Texas and the southeastern US that have comparatively light congestion for their size.

by chroem- 7y ago
Then why are there popular cities that aren't congested? (And coincidentally have lower costs of living)

Will this have any implications for astronomy?

They check the airframes with nondestructive ultrasonic testing that doesn't involve oblitering entire aircraft. That would be caught at one of several different QA points. We're mostly talking about design verification, which i

Absolutely, but NDT is a far cry from testing an aircraft to failure.

It's not software: it's mathematics. You don't build a bridge by successively creating bridges with more and more structural reinforcement until the bridges stop falling down. Instead, you calculate the appropriate size of

The annular wing is an interesting touch. It should reduce induced drag at the low Reynolds numbers these drones typically fly at, by eliminating the wingtip vortices. I was working on a very similar design for a while, and I placed the p

Composite structures don't tend to be very repairable in general, but if it's localized damage usually you will just glue a patch in place.

by chroem- 8y ago
They use LiFePO4 so it's chemically inert, and it's protected from shorting out due to mechanical damage because the entire composite acts as a thermoresettable fuse.
388.
by chroem- 8y ago
They use the same Li-Ion chemistry, but structural composite batteries are on the near term horizon. You get extra capacity "for free" since they also serve as the physical structure of the car/cellphone/aircraft.

They're essentially doing surrogate model optimization, but using a neural network instead of Gaussian processes. This is the same way that the control policy for the MIT Cheetah robot was created.
