Which one, where at?

Wild-arse guess here; but I see that your holes are vertical, and those are just above are in a horizontal band. Maybe possibly that's setting up a vortex to swirl/heat the air (and maybe diesel vapour) in a donut shape? Would love to see film of that one runnng please @AllTorque

Old man cat from the front got a leccy blankie for the incoming bad weather Aiming for a bit less than 180°C this 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

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

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. Someone diddle fingered the paging files settings

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

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. (Arduino library here: https://github.com/WifWaf/MH-Z19)

Philips? https://diystirlingengine.com/stirling-cycle-engines/ (evilgrin)

That's way cool, but surely heaps safer to use water - like from a waterblaster. (Less spring pressure in the gas)

You could run your alt off the driveshaft; if you're parked up, you can throw a charger at it. It'd be interesting to see how wide a speed range the reg would cope with. Or off a cam shaft? (out the front, up high?) or roll the belt over pulleys and yoink it out sideways?

... what the hell do you mean it failed when the customer was using it upside down at 10000m altitude and it transitioned from sunlight to -40C and ice formed on the wingtip and the drag co-efficient of the electric thruster changed? It was just supposed to be a trim clip for a Kei car! I've concluded lately that real world testing clarifies the customers needs, (not their stated intent) and also tests some of the assumptions you/they didn't know you were making.

I love the concept, where instead of making some cad model which is only an approximation, and spending forever on tuning the FEA to try and replicate the measured points, boom - measure everything. I reckon there's a biz in plonking solar powered versions of these looking at bridges for preventive maintenance / failure prediction. Esp in USA, where the neoLib brainworms means no one spends on infra maintenance.
