This guy was in a remote controlled, parachute equipped gondola at 17km altitude wearing a pressurized suite. His suit broke and even though the emergency descent of the gondola was immediately activated to descend safely, he later died from embolism (bubbles forming in the blood because of rapidly decreasing pressure). Passenger jets cruise at about 11km so i gather it would be similar.

Other commenters have pointed out the problems with overloading of connectors and reduced efficiency because of the added resistance but there is another really important reason not to chain power strips: circuit breakers work best against short circuits when the resistance between the breaker and the short is fairly low (for instance less than 0.5Ω) so that the current will quickly go over the rated current of the breaker. If the resistance is a lot higher because you have too many extensions between the breaker and the fault, the time the breaker needs to react will go up. Counterintuitively this usually means more energy will be turned to heat by the fault.

In extreme cases this can mean the difference between a broken power strip that you can just throw out and a burned down house.

that is not a power plant. a power plant supplies power…

What makes them think that the library of Alexandria did it any other way? Nerds have existed long before the internet…

also: you can calculate the carnot cycle efficiency of a solar cell as if it was a classical heat-power-machine, even though it has no visible moving parts.

the reason why this works and yields realistic results is because the basic principles of thermodynamics stay the same no matter if you are working with steam, combustion gasses or photons and electron gas inside a semiconductor.

downvote for lack of feathers. smh.

you mean turing complete?

this is extra tricky because they did not specify the exact kernel. mainline could be any of the kernels tagged as stable that you can build from linus' git tree. i know that in the past you could run a mainline linux on intel 368 chips but today you probably can not because official support was dropped a while ago.

I think what he was trying to point out is that you should not expect a direct visible effect of the dwindling funds on the events on the battlefield. It will be much more indirect and delayed by month, maybe years.

your text seems to agree 100% with one of the examples in the original posts text: ”[…] immigrants who […] simply sought better lives for themselves and their descendants“.

could you elaborate why you think it is wrong?

I think it went a bit further than just selecting the right paint.

I remember there was a program to enhance the stealth for relatively low flying surveillance aircraft (still mostly propeller aircraft at that time) and one of the most effective measures was painting the underside of the plane White and then illuminating it on purpose with a light that was matched to the sky. The light was usually bluish to match the sky. https://en.wikipedia.org/wiki/Yehudi_lights

The reason why this was not simply done at night was of course that the surveillance equipment needed some light to work :)

Looking at the price per kWh for commercial batteries tells me that we are seeing the battery revolution right now.

Graphene is already commercially used in some applications:

There are already very effective cures for some types of cancer (note that the differences between the many types of cancer can be huge and so the effort and time needed to create cures will also be very different. some treatments also are effective but not completely understood yet, like for bladder cancer)

Nuclear fusion devices are commercially used in material analysis (mostly in the semiconductor industry and in ore processing). There are different types in use – some even use thermonuclear fusion on a small scale.

It all seems like super crazy superconductor level tech until it becomes mundane and part of peoples lives ... then we stop noticing how amazing it really is.
