Super interesting project: @CarnotCompress, working on a more efficient / quiet air compressor design, and they're now raising funding. This is a huge problem if they actually get this working. Where's the industrial investors at?https://www.startengine.com/carnot-compression …

Glad to see a practical isothermal compressor! Does it use evaporation or just conduction? Is the wet air output a problem, or is the air somehow dried?

Seems like it uses water / radiator and the compressor is somehow drying it (perhaps by centrifugal force?)

Possible it uses increased effective density of the air via droplet emulsion to get high compression on a single stage. At high enough isothermal compression ratios, the air could theoretically come out drier (per mass) than it went in, once you separate liquid. Neat!

Yea totally - I like to see industrial hardware startup as opposed to just the consumer gadgets you usually see. Their biggest issue is probably that most tech investors think air compressors are something at Lowes, not a multi-billion dollar global industry.

Biggest thing people will miss in investing here: if this works, it has a strong chance of becoming very cheap very high capacity energy storage for renewables and grid stabilization: isothermal compression is EFFICIENT. This is a huge opportunity and only getting bigger.

This was the idea behind LightSail actually, but it's a really hard problem. I'm sure
@DanielleFong could regale us with crazy stories.1 reply 0 retweets 2 likes -
we did a 200 bar two stage compressor with water spray, it was reciprocating, not a centrifugal, we did custom water injectors and valves so that we could compress and expand across a wide range of pressures worked well, problem was consistency of funding

there was still a lot of development work to do when our lead vc decided to stop funding the compressor expander to focus on our tank tech. they are working at a much smaller scale which may save them money, will be impressive to see what they can accomplish with just a million

Thanks
@DanielleFong@NickPinkston@palladiummag for your interest. For now we are operating at 100-150psig.4 replies 0 retweets 2 likes -

The compressed air is saturated at a low temperature so there is minimal moisture in the air compared to adiabatic
