I"m thinking this might just work in the Mooney, power draw doesn't seem to be outrageous. Plus would only need for takeoff and landing. all else fails use it when i go fishing Mark 2 Specs (zerobreeze.com)

Well here is the site the OP linked to https://www.zerobreeze.com/pages/mark2-specs ‘I don’t see where it says BTU, and I never said it was a Peltier plate, I said many are, and those that are are essentially worthless. ‘However 2300 BTU isn’t bad at all, smallest window unit AC I’ve seen was 5,000 for example. ‘I’ve got quite a bit of experience through others with these “miracle” battery powered airconditioners with people with sailboats, everybody wants something that can get them through a hot night, or at least cool the cabin down enough to get to sleep, and unfortunately it just doesn’t exist, Airconditioning on a boat requires a generator at some time. Average smallest window unit AC (5,000 BTU) pulls after start up about 6 amps at 120 VAC, that’s about 720 Watts and that’s just under 1 HP, and that’s a LOT of power. Sure it can be decreased some by using expensive components, but not by much. ‘It’s also 60 amps at 12V, which is of course is everything a lot of our alternators are capable of producing, for a battery to supply 60 amps and not be real heavy and or real expensive for any amount of time would be real impressive. But this unit is 2300 BTU, so “only” half that, but 2300 BTU still takes serious power, 30 amps at 12V, which isn’t trivial at all, maybe 25 or so is realistic ‘Of all the small compressors available the Danfoss type has been the best for a very long time both from a service and from an efficiency standpoint, they get there by being brushless DC, which means among other things that they can be variable speed. All of the new house type AC’s, refrigerators etc that advertise they are ”inverter”units are actually brushless DC, because that’s how brushless DC motors work, and they can be more efficient, just not a whole lot. https://www.danfoss.com/en-us/products/dcs/compressors/compressors-for-refrigeration/direct-current-compressors/#tab-overview Recently Sawafugi developed a neat new tiny compressor, they call it a swing motor, it’s fascinating in its simplisticty, it’s just a piston and a spring that’s actuated by an electromagnet for the compression stroke, and the springs do the intake, then select springs who’s natural frequency corresponds to the RPM of the compressor and your compressing a gas without an electric motor and crankshaft etc. Real neat, but unfortunately it’s not more efficient than the Danfoss. But lots less moving parts and may last a very long time, bu sealed compressors like the Danfoss often run for 90,000 hours or more, so that’s tough to beat. https://www.sawafuji.co.jp/en/technology/swing_motor/ The bottom line is that unless or until there there is a large breakthrough in efficiency like LED’s were for instance in lighting, that effective airconditioning in small lightweight units, especially battery powered ones just isn’t possible. Still I’m impressed with 2300 BTU out of a 17 lb unit, but have to wonder about battery weight and expense as well as run time, because 2300 BTU takes quite a bit of power. Portable small airconditioners, especially battery powered ones are very similar to an electric airplane. It’s possible I guess, just not with current technology

This is the part of the site that gives a tech hint of what it can do... https://www.zerobreeze.com/pages/mark2-design-technical Looks like a mini window AC unit... Essentially it is too small to cool a whole cabin... Kind of complex to handle the warm air it generates... Put it in the too good to be true file... Using it while going fishing... sounds like the only way this will get used... unfortunately... Make sure you know where the warm air and moisture are going to get dumped... Best regards, -a-

I expect the zerobreeze does the same for condensation as all the other 'portable' units, fling/spray it onto the coil and let it evaporate and go out the exhaust pipe. Looks like a pretty bog-standard 2 tube portable unit just smaller.

https://www.zerobreeze.com/products/zero-breeze-mark-2 Wow! Looking forward to the pirep. If this works as well as the YouTube video review suggests it is groundbreaking. 17lb battery operated remote controlled air conditioning for your Mooney for 3-5 hours with no load on the engine or alternator and no ice to pack or water to drain. You would need a way to vent the hot air exhaust but other than that.....

Has anyone ever thought about one of these battery powered units? Meant for small spaces and camping. https://www.zerobreeze.com/products/zero-breeze-portable-air-conditioner But it seems to be pitifully low 1100BTU. ...other than that. It would be good. Since flying is a special application where you mostly only need it often when low, during tax and take off and then at altitude its cool so turn it off. So battery powered seems plausible.
