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

of course, on a city-sized boat

I’m Gwen Danielson, a neuroscientist and bioengineer, who decided as a child that I would end Death

thiel jumpscare

they could be just as well from cambodia for all we know

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

e2ee is not enough you also need to know what these ends are

there's a lot of complicated tubes in refinery, each with hideous lead time

damn i wish i had confidence of a mediocre techbro. twitter thread suggests that there's four copyright infringements just in these two images

e: still can't get fingers right, lol

Shadowban is when you can see your own post/comment but it's unsearchable or otherwise unreachable by other people. milder variant is comments hidden by default, some of them look like deleted by mod but it might be automatic. the point of shadowban is that you don't know about it. this is something different, why it happened to you idk but there is some trade in old accounts for spam purposes, maybe that's why

lora bitrate and radiated power are tiny and such considerations are only important in peacetime. gps is jammed now routinely and it's more important than 95% of iot dogshit. telemetry and remote control that matters is either wired or has reserved separate band, like power grid switches. not sure wdym by logistics

you also have to be stealthy and if you emit you're seen and if you're seen you'll be found and soon dead. lora doesn't help you with that especially if you increase power to overcome jamming. using starlink in iran now for example is a capital offense. last time i've checked, irgc ew looks for starlink wifi and they can find it even if it's renamed because of its distinct signature. it takes less to spot lora. they do not look for uplink for some reason but they try to jam it and downlink too

okay so they want to use layer of soil as a sort of seasonal storage. fine; this part works. 1. who's paying for all these residential heat pumps? 2. this kind of arrangement means a lot of digging and drilling. it takes one (1) nimby to stop it in its tracks and all these earthworks also cost money 3. at this point it's way simpler and cheaper to just use solar collectors to top up heat reservoir in the summer, as long as heat pumps are paid for. also these same solar collectors would just provide hot water in summer directly

were they advised by rube goldberg?

also, your local university probably has a kind of stability that makes years-decades long commitment worthwhile, unlike some sketchy bloated startup that probably dealt in crypto seven years ago
