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

if there’s will, there’s a way

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

of course, on a city-sized boat

only after years of kicking and screaming, and companies that made CFCs switched to more expensive HFCs and later HFOs so it’s not like they went out of the business. (alternative is use of hydrocarbons which is much cheaper but flammability was used as a reason to restrict their use) CFCs are also still used as chemical intermediates and as late as during covid there was an operational illegal R12 factory somewhere in northern china

they stood no chance, never knew what hit them

You might be better off exchanging them before travel, you would need to look up rates

perhaps, but only americans bitch about it so loud that you can hear it across the ocean

average euro prices of fuels would kill american on contact

there was chrome (and firefox probably?) extension that went through your all fb liked pages and unsubscribed from them so that when it’s done timeline is gone entirely. fb went after its dev, removed that extension and banned him forever because it kept people off fb https://www.businessinsider.com/facebook-bans-unfollow-everything-developer-delete-news-feed-2021-10 doing this all manually still worked back then, not sure about today

Facebook’s letter took him by surprise, he said, adding that Unfollow Everything had only 2,500 weekly active users and 10,000 downloads.

“It was definitely growing, but it wasn’t huge,” he said.

“Apart from that I just very much saw it as something that improves the Facebook experience for Facebook users,” he added, saying he got “amazing feedback” from people saying they “were using Facebook in a way that was much healthier for them.”
