lots of exciting battery developments in general, especially if donut labs by some miracle is not a fraud.

it was a bit worrying as there was somewhat of a stagnation in battery chemistry, but having non toxic/dangerous battery storage is going to make off-griding so much more attractive.

technically speaking, if every household had solar panels and batteries it would not only be cheaper than the grid it would also have complete independence from oil fluctuations, weather disasters and centralization.

now if you combine that with electric cars that charge off your off-grid system and transition to eletric appliances instead of something like gas the benefits keep stacking all while being pretty much net neutral post manufacturing.

As an owner of household solar panels, there are weeks, sometimes even months with very little solar products, especially during the colder months.

While I don't regret getting them, they are absolutely not good enough to be the only solution.

I have had a set of panels on my roof for years, but I think going off grid is overrated unless it becomes drastically cheaper than being on grid.

Grid level batteries are going to be a more efficient way of using the same materials to achieve a particular level of supply. It's just at the moment there's a "competency arbitrage" where infrastructure is way slower than building it yourself.

People just don’t realise how energy intensive a manufacturing economy is.

Which is fine if your fantasy includes offshoring all of that and shipping the finished products in to the local market.

Which, no matter how you slice it, has to be more energy intensive than manufacturing locally.

High density housing is unlikely to be compatible with that.

Also rental dwelling owners and people with limited economic resources tend to be less likely to make those kinds of capital investment.

Absolutely not, economies of scale. To say nothing of the cost incurred when an issue appears with your installation (lightning strike, water damage, etc) would be much higher.

"it would also have complete independence from oil fluctuations..." Indeed. A foreign country can't turn the sun off. And yet Trump.

(Pardon me if you live in another country. I'm starting to wish I did.)

"weather disasters "

Solar does seem to be influenced by those, though. So before battery storage is really, really cheap and plenty, for off grid situations I do would prefer backup gas as well.

Having some natural gas purely as a secondary emergency heat source is well worth it IMO.

Interesting that the script has flipped, now china is leading breakthroughs and hardware startup culture is perpetuating frauds
