Notorious b.s.d. posted:i don't think fusion will ever be a source of electric power, period. not in my lifetime, not in your lifetime, probably not in the lifetime of our species what if you did two project orion ships on the end of massive arms with a generator in the middle? that'd be fusion power generating electricity! i suppose if you don't fancy letting off all those bombs on earth (and we've got australia just sitting there doing nothing) we could do it in space, and beam it back with massive light bulbs so solar power can work at night.

President Beep posted:what if........... Wait, but if we had all the cars roped together somehow each one wouldn't need it's own motor. There could be one (or more) of these motor-having cars (let's call them "Engines") at the front or back of the line of cars to pull or push the connected un-powered cars. That would be a great idea!

silence_kit posted:when solar cells get warm, their efficiency degrades. hopefully when they evaluate this idea, they include the solar cell efficiency penalty and/or necessary refrigeration energy cost when running the solar cells at intensities of what I assume are many many multiples of 1 sun. if you've got a literal sun sitting there you wouldn't use photovoltaic for energy capture because you don't need to spread out over a larger area to capture a reasonable amount, you'd use it in a heat exchanger to generate steam so it'd be more like those solar concentrator layouts with the mirrors its funny I wrote a research project on solar Stirling engines like 12 years ago and the my were looking like a great idea as they we 40+%efficient so beat solar pv but turns out they're a bitch to maintain and solar pv got way better and cheaper than I thought Stirling engines are still useful for low grade energy reclamation though

just lol at this. you can model traffic as a fluid flow and iirc much like chokes in flow a jam is like an emergent property or a non linear system that you can't just control away also jfc: a shitlord posted:even if the regulation had passed, and required existing developers to retrofit sprinklers into older buildings, Grenfell Tower might not have gotten a sprinkler system before the fire occurred. yeah probably don't bother with fire regs at all then I guess? what a loving moron.

Still, a good meme. Deteriorata posted:If vehicle-to-vehicle communication is part of the autonomous systems, they can stay much closer. The safe gap is for dealing with human reaction times. Deteriorata posted:No, that's not what it means. It means that it takes anywhere from 0.5s to 2s or more for your brain to perceive that the stop lights on the car ahead of you are on until you get on the brake. This is called "reaction time." Your car continues to travel at full speed while your brain is figuring out what to do. Devor posted:The reason that a platoon of autonomous vehicles can not only reduce most of that yellow distance, but a lot of that red distance, is that every car in an autonomous platoon does not need to be doing "Is the roadway in front of me safe" checks every moment.

I didn't say it was a good proposal. silence_kit posted:that reminds me—during the height of the solar cell research/funding era, with Solyndra and all of that, the US government funded research of transparent solar cells lol it is actually a lot less dumb than you are thinking. the idea is for the cells to be transparent to visible light while generating electricity with the IR and UV light. the potential application that always gets trotted out is having windows that generate power but the really big promise imo is in placing a transparent PV on top of a traditional Si PV to make use of some of the 500W/m2 in the IR band that currently is completely unused by PV panels. you might even be able to retrofit it into place to give an efficiency boost to existing installations. too bad IR photons aren't really energetic enough for true PV operation.

lol at thinking that anything at all is solved by simply increasing roadway capacity by getting cars closer together to improve traffic density and especially lol at thinking that stupid human-driven cars don't already perform this behavior... when they're in stop and go traffic since that's what traffic congestion already is like just think about it even medium hard that's clearly not the problem

JawnV6 posted:they can make hot mirror/cold mirror coatings, why would this be impossible Usually when materials absorb IR, they absorb visible light too. There may be some way to engineer a reflectors on both sides of the cell to force IR light to make multiple round trips within the very thin cell until it is absorbed, and to force visible light to only make 1 pass through the cell. The visible light would still be attenuated but maybe it wouldn’t be that bad. silence_kit fucked around with this message at 20:42 on Feb 16, 2018 |
