In general, I think Causer Pays is more fair than User Pays (e.g. the polluter should pay, not the victims)

I do wonder if many/most bike injuries are self / car inflicted.

Electrolysing hydrogen sounds like a good time

If I used the right calculator, it's only 3m^3 for 10kWh at STP (100% efficiency).

That's just a big garbage bag, and if it fails, it just floats into the air, yeah? I'm guessing fuel cells run on it?

I was more thinking some beige transport appliance for your Middy (Leaf ?), and the V2H (vehicle to house) bi-dir charger, like this class of device: https://www.mysolarquotes.co.nz/blog/electric-vehicles/enphase-shows-off-game-changing-bidirectional-ev-charger/

Yeah, up to 10kWh in a hot water cyl, is def cheapest domestic energy storage. But you can only drink so many cups o tea. Hey, is there a solar to Nissan Leaf box? I have an idea on how to get rid of the rattle in the X1-9.

Seriously tho, an ev you can draw from makes good portable battery

OK - scrap iron and brass batteries then?

Or if you're feeling frisky, just electrolyse water and put the H2 in a big rubbish bag

^^ need more head

If you look into the datasheets, some PSU ( and possibly/probably some chargers) are OK with 320V DC in (peak mains V) and some up to 600V in (hey have internal boosters to 600V anyways).

So that's only 1.3A per kW. have to be careful with the switching breakers and and fusing tho - DC is a bit harder to break (including quenching arcs)

If if any maniac suggested a pair of microwave transformers, FFS use them well isolated and put ELCBs around them

this makes the power cabling back to the cabin very lossy

Nah, just yoink up the volts a bit. 48V is extra low voltage, but will still need enough copper for 20A/kW, which is a bit beefy, but if there's a way to run 230V / 600DC in ditch, you could use doorbell wire

It is to make an air battery, basically use the excess solar I generate to pump air into a large tank. Heat shouldn't be too much of an issue as I wouldnt think it would be fast.

But a slow high pressure pump is key, I am just not sure what that is.

Why air? for shits and LoLs, or for cheap storage / direct mechanical?

I see you're looking for 0.6 * 24 is about 14kWh, so $pendy conventional  battery.

You got a handy hill? Pumped mini-hydro?

Also, there's some cheap big electrical battery tech I've been considering playing with.

Oh, that's why my dev PC has been completely sucking lately.

910ppm?! did you get the Dai to idle overnight?

Just existing in a small bedroom/office while making kiddo a low rent gameboy.

Keeping the door shut so as not to wake middy and kiddy

Hmmmm. That figures

Was down the river on the dirt bikes with the boy recently. The throttle blipping by spoiled rich kids on expensive small euro 2 strokes was deafening. We had to leave. Old fart rant out.

TiL euro 2T are still a thing. I thought the new hi perf 4T motors had gobbled up the racing, and the consumer market had followed.

I finally got some WFH done after a grot week with a cold, and I had the office window open, so tonight I tidied up the wiring and software for an MH-Z19B  CO2 sensor I bought years ago.

I guess I'll just shove it in a cardboard box now, with hot glue.
