The cost is 450 euros including shipping
but they require a wire transfer (won't consider paypal or credit card). For me that means about $80USD more to send them money
Their power consumption
seems better than most. I've found several Peltier units to build one from, but the power draw on them is 60W vs 36W. That's actually better than my fridge (which no longer works). I'm considering trying to build my own with a cheap
chinese peltier device using the old frigonautica case.
It's a shame you can use this to blow a nice cool breeze over your body while you are trying to go to sleep but I don't think it would be able to handle the volume of the bedroom and it would be just a waste of power.
It might be built on top of this unit:
TEC1-12703 30*30 12V3A
Maximum temperature difference:65 °
Dimensions:30 * 30 * 3.2
They do offer a slightly larger (and more power expensive) chip as well, now I just need to buy some small microcontroller gear
and see what I can come up with....
TEC1-12704 40*40 12V4A
