Altman has been claiming chat gpt made him feel dumb since 4.5

perfectly believable tbh

that mmwave radar would have to be attached to a drone, because their manned aircraft are unbelievably obsolete. it means smaller size meaning low resolution, and as starlink emits pinpointing them would be very easy when active, much easier than any passive sat dish, and starlink is still in use. i’ve seen some advice on hiding starlink that includes turning off starlink wifi and using wired connection, because irgc is looking for 2.4 ghz signal (from ground?) and not for 14-ish ghz uplink, so they probably dont have a lot of flying ew/radars

i’m not saying that iranian air force has definitely none of that, but i would be decently surprised if they do have more than 2

there are ways. for example, put a fake hot water barrel on the roof, made from fiberglass or polypropylene or what have you, but not metal, and put dish inside, or in any variety of inconspicuous containers or boxes made from plastic or wood or fabric. some other antennas can be camouflaged as fake chimneys or gutters or water piping or many other things

If one were to make hydrogen producing solar farm specifically, this could have made sense if there were efficiency gains compared to pv + electrolyser. But there ain’t, and from what i understand won’t be

Ye i’ve seen that before. Perennial problem with this aporoach is that efficiency is capped below what pv panel can get and also now instead of wiring you need to install purified water + hydrogen plumbing. Also while you just can use only excess of generation for electrolysis, this is always on

quixotic, even

Stirling engines are woefully inefficient tho, PV panels are better unless you’re intending to supplement heat source with biomass or such. In a climate where most of energy is used for heating and little to none on AC, it just makes more sense to use solar collectors instead of PV because most of energy use will be in form of heat anyway, and per square meter collector will deliver much more. If you can couple excess heat production to seasonal energy storage, this gets you most or all of heat needs year round covered by solar, if you don’t there’s still free hot water in the summer and seriously lowered gas bill through the year. Small PV panel might make sense to keep pumps running or cover some of the rest of needs but won’t shift balance heavily either way. In a place where major use of energy is AC this approach makes no sense and PV panels with daily or a bit longer lasting storage of energy, be it in batteries or thermal (tanks of cold glycol or ice or whatever) would be the way to go, because the most sunny day is also the day when you need AC the most and this way you get most of your energy needs covered

some goods and intermediates have large energy content, like, if you wanted to use energy from large pv farm in, say, morocco, then it might make more sense to ship bauxite in and aluminum bars out (it takes some 50MJ/kg to make aluminum)

simplicity of the system would be a factor in small, unattended installations like for space heating for single home

Pain

if you’re interested in heating only, then geo-solar hybrid might be better for you. the point is that excess heat from solar collector gets stored in soil near borehole, which can be used for heating in winter. solar heat also gets you hot water year round, and it can be made to work with heat pump or without

all of that without heat pumps too

It is a liquid that after irradiating stores that energy while still cold and can be made to release it in form of heat on demand. but also it’s low grade heat mostly useful for heating and not for electricity generation. It would be simpler to just build long range transmission lines or put energy intensive manufacturing near PV farm in sunny region

it’s transparent too so you can just put pv panel underneath to capture the rest

you get 1.6MJ/kg just by irradiating this thing, nothing else is needed and its storable for months as noncorrosive room temperature liquid

to make ammonia you need to have pv to turn light to electricity then make hydrogen out of it then make ammonia in haber process, each step generates losses and none are practical on small scale

there is a problem that it can heat itself up so hard during decomposition that it can just go on without catalyst

aaand it boils water again

i guess this is partially because chinese opoid users die from bullets and not from overdoses
