Vince, I got interested in that vortex heater/cooler thingee you linked to and read up on it. It sounded so good and cheap that I began wondering why EVERYBODY isn't using it. 170 degree air out one end and -30 degree air out the other... that's a phenominal 200 degree difference!! Run it one way, it's a wonderful heater; turn it around and it's better than any freezer out there, and is a great air conditioner too. And it looks like it could extract large quantities of water from even very very dry air... like deserts?
They say the thing uses no electricity, but it uses compressed air which must be compressed somehow. I finally
found a price list which, if I understood it, promises one of these gadgets for anywhere from $1687.20 to $2752.80. Heat pumps and exchangers topped out at $5791.20.
OK, so why ISN'T everyone using them? Why aren't they being sold out of every hardware store in the country for people's homes? The closest I could find using google were these
vests which are selling online for
$300-700. I didn't find anything "house-sized". If they are really that good, looks like they would spread quickly!!!
As far as CO2 being heavier than air, I would expect any turbulance to MIX the CO2 with the rest of the air, and for only very still air (like that down in mines) to become stratified so that the CO2 goes to the bottom, no?
In faith, Dave

This morning I read my own obituary in the paper. Wow! I called a friend and asked her if she had seen it; she had, and her first question was, "Where are you calling from?"
