One of the biggest drawbacks to AC is it robs the engine of HP. Another key drawback is that because its belt driven off the engine the engine has to be on for the car to utilize the AC. This technology does away with this inefficiency and inconvenience as now you can have AC whenever you like. Even when the engine is in stop and go traffic or at a long stop light the small BLDC motor ca be configured to shut down your car and allow the AC to still run. Then when the light turns green the BLDC motor will turn the engine back on as soon as you press on the gas pedal and you are off all without ever loosing AC in your car. So no more rolling down your window during a traffic jam
Here is a link to the small BLDC motor AC system unit for any vehicle. This can also be applied to EV only vehicles.
