Sorry to borrow Jack's opener, but I think my announcement related to this topic was buried in one of his last threads. My apologies for the redundancy.
I'm introducing a product I put together whose purpose is to provide localized cooling. It's called
MPC (multi-purpose-cooling). Not high tech, but uses a proven principle (Latent heat of evaporation). It uses a high pressure pump to force water (!) through special misting nozzles which creates very small droplets. The resultant mist quickly evaporates to absorb heat from the surrounding air. On a hot day, the heat reduction should be at least 15-20 degrees cooler. Many uses, especially for track cars.

I'll be in Cambria this weekend with a portable demo unit in case anyone is interested in a looksee.
