I would really like a setup where my roof top solar panels makes me self-sufficient for energy needs, but the key hurdle is battery storage. In a town house in Netherlands, for a family of three, I use on an average 250 kWh of electricity (excluding heating by gas) per month. I’m getting solar panels installed in my roof to the tune of 10 x 420wp panels expected to generate 280kWh of electricity per month. My primary…

If even battery fire risk bothers you, you should really reconsider burying bombs in your backyard.

Compressed gas cylinders are _terrifying_, a larger one with an inert gas could level your entire house, and a hydrogen one could level the entire block.

Wasteful is relative. Our house produces 250-300% of our usage most days, but 5-50% of our usage some weeks. Heating and cooling (and the computers that manage the batteries, which draw about 200W, including internet!) is hard to timeshift, but everything else is easy to move to sunny days. Anyway, on those sunny days, electricity is literally free. I wish I could just dump it into a magic box that pulled charcoal ou…

At some point I got an itch and looked into what it would take to run such a magic box myself. The lightbulb moment was realizing that of I did manage to pull a ton (or 15) of carbon out of the air by whatever method, I would then have to move that carbon... Somewhere. I had been looking especially at algae bio reactors, which leave you with a particularly soupy waste situation. :)

Bury it to do terra preta…
