It also turns out that not many people have 3-phase power and can support a heat/power load of 15kW in their homes ;)

I actually suspect it would be a lot easier to support 15kW of power in my home than 15 kW of cooling.

I know several people with 2x 240V 32A 3-phase in their garage, that's 20+ kW at any reasonable power factor. But a 15 kW cooler that would work in summer would annoy the hell out of any neighbours living closer than a mile.

Simple solution: Turn those neighbours into shareholders and they can sleep to the sound of money all summer long :)
