Reply to comment by reallyfatjellyfish in International scientists find Earth is ‘unequivocally’ in midst of climate emergency. The report shows new data illustrating increasing frequency of extreme heat events, rising global tree cover loss because of fires, and a greater prevalence of the mosquito-borne dengue virus. by Wagamaga

Maybe something with a little less potential for starting even more fires?

Are cryobombs a thing yet?

Reply to comment by bl0rq in NASA has invented a new type of high-performance battery that researchers claim could be used to power fully electric airplanes. by phife_is_a_dawg

It is, but it requires pumps, heavier engines, etc. to run, and only convert their energy into motive power with around a 30% efficiency compared to the >90% of an electric motor. The batteries are catching up in real terms faster than a simple comparison of densities would suggest.

Not no byproducts, but significantly reduced. You can't control side reactions, however unlikely they are. B11 + He4 (the expected byproduct of p + B11) = N14 + n. There's also a rare p + B11 = C11 + n to watch out for as well.

It's a massive improvement on every reaction shitting out neutrons though, and because the main byproduct is a charged particle you can use direct energy conversion instead of going via steam which means the energy output threshold for viability is around 60% of what it would be otherwise.

*C11, not C12 sorry. That then decays with a half life of 20 minutes back into boron-11.

Reply to comment by Grayox in ‘A growing machine’: Scotland looks to vertical farming to boost tree stocks. Hydroponics unit can produce saplings six times faster than it takes to grow them naturally outdoors. by Sariel007

Iceland is very similar, though getting better with reforestation efforts. The problem that far North is the trees grow incredibly slowly, and when they're small (which they are for longer), they're vulnerable. That's the real benefit of this machine, you skip the bit where the deer eat all your saplings and you're back to square one.
