https://maps.nrel.gov/psh (us) Europe has Norway for storage, but limited renewable potential compared to the US or China (not nothing, offshore wind is a thing, but the available land area for solar is very limited).

Bulk ordered, that is probably a ~$50k laser. Not nothing, but on the scale of medical device costs, not terrible.

The assumption by insurance commissioners (elected officials) is that private insurance will result in better outcomes in the long term, and profit margins are regulated and this is the will of the voters. ... Now that doesn't mean it

Yes, nothing here is really new. For inference, trits/sec decoded into L1 cache is a lot more important than random access, and is going to be hardware specific (e.g. what SIMD instructions are available). 8bit seems an odd choice give

I am partial to astropy, eg from astropy import units as u density = np.linspace(0, 1, 10)*u.g/u.cm**3 mass = (density*1*u.m**3).to(u.kg)

(disclaimer that I do work in a related area) The novelty of the underlying paper notwithstanding, a quick scholar search for "gas diffusion electrodes ptfe copper" will show that this is hardly an unexplored space.

My understanding is that there are lots of existing corals well adapted to high heat/low pH, mostly from shallow atolls. ... But, if you transplant them they get outcompeted immediately. Corals are constantly engaged in a WW1-style tre

I wouldn't call it enormous. Some datacenters run dry cooling. A large datacenter (100MW) that uses evaporative cooling probably uses ~1000 acre-ft/yr, on par with a medium farm.

Apologies for being critical, but this reads like the author had a conclusion they wanted to reach and worked backward to some flashy graphs to make it work (the right side of the "lies, damn lies, and statistics" spectrum). There

Sure, it's kind of a terminology question. There is heat being continually trapped by the SLCP, which analogous to a one-time (large) release of CO2. The earth will warm up in response, and will keep absorbing heat from the SLCP as lon

> “one time bump” to global heating That's not entirely accurate. Short lived climate pollutants (SLCPs) that are being continuously emitted (e.g. SO4, NOx, contrail-cirrus) have cumulative effects. The heat trapped on earth is cumu

Yes it would ablate at some rate, based on the drag, convective buoyancy, etc. If the smoke is optically thick at all, even if it pushed away almost immediately, the wall ablation rate would probably be a couple orders of magnitude lower th

Or just something that gets smoky when it burns, then the energy is deposited entirely into the smoke boundary layer (and might even make a nice reflective plasma).

Solution (2) as written seems to imply that the camera can only use the gyroscope signal while the camera is pointed at the subject, but I cannot see why that is a strong limitation. In theory, you can take the last N seconds of data from t

It might be simpler to mandate accounting and (progressively) tax production to pay for remediation to force the market away from polluting. And maybe it would encourage more out of the box solutions, like this one: https://arste

... Are they the same engines though? Don't get me wrong, it's impressive that the pressure tanks can take that many cryogenic cycles, but I am not sure I would call it the same "rocket".

Well... (if I am calculating correctly) A tomato plant is roughly ~40lbs/sqft/year (hydroponic... at 40W/sqft). That's a bit higher than the 80kg/m^2 estimate, but I don't have the wattage requirements for the

Sounds like they are slowly learning electrostatic PIC codes from first principles.
