Something isn't right. The 18cc version shows "1-3kW" but if one does the calculations: 12V x 30A = 360W and 12V x 55A = 660W ?????????Dave,
A couple of the Ultima guys use this one, but is not inexpensive…

Thanks Howard. I slept through "Heat & Thermodynamics" class.
Stop-and-go traffic is probably when you'd need AC the most.STOP and go traffic would be a problem but highway speeds or even low continuous speeds would still turn the compressor at an adequate rpm to function. Compressor speeds would need to be something like 1000-3000 RPMs I would think. A 27-inch tire turns about 350 RPMs @30 mph and a little over 1000 RPMs at 90 or so. This seems to indicate a pully drive ratio of about 3 to 1, again readily available pulley diameters around 2 1/2 to 7 inches would work.
Chain drive with a bicycle ratchet pulley?Stop-and-go traffic is no place for an SLC. A Prius is for commuting to work and back.
The thing that ended my plan above was rolling backward. I couldn't think of an easy way to address that one. I don't think an AC compressor would like to be turned backward.
