- grim_io 8mo agoI don't quite believe this. Is it really better than just using solar panels to run a heat pump?
- pidge 8mo ago> Our core innovation is a radiative cooling material that we’ve combined with a panel system to improve the efficiency of any vapor-compression based cooling system A heat pump is a “ vapor-compression based cooling system” so that tech is an addition-to not an instead-of. Whether it’s better probably depends on how expensive the additional efficiency is in practice. > SkyCool’s Panels save 2x – 3x as much energy as a solar panel generates given the same area. So if you’re area constrained maybe.
- grim_io 8mo agoThat's very hard to believe. Radiative cooling is really bad compared to any kind of fan in front of aluminum fins. Air itself is an isolator, there is a reason you need to shove in fresh air to take on more energy from the heat source.
- morshu9001 8mo agoThis looks like it depends on the outside air to cool the coolant. "Radiative" can mean that too, not just IR radiation.
