  • ""almost" in this case is less than which is what 400 is relative to 700 ;) Seriously it would be cool if there were kits where I could build shelves of any form or size with this technology. Really the honeycomb is the only thing not easily available. "

  • "Very skeptical here. If you live in a closet and need only a few degrees of reduction 5000BTUs will do the job. I have a large bedroom and 12,000BTUs does not cut it.No information is given as to efficiency either which makes me nervous."

  • "As an engineer/Diver since 73, I would LOVE one of these units....except they are like one of my other wants...perpetual motion machine. Some people have gone into all sorts of analysis showing how many liters of this or that. But there is no reason to do that. When you breathe underwater you take in ONE FULL lung full of water per breath. This device would have to produce that for every breath since it does not have any way to save any of your exhale. You breathe about once every 4 seconds. How much water passes over those motorcycle handles in 4 seconds....close enough for extraction mind you? Next, you have to overcome the affinity of the gases to water...as in negative pressure creation. Your lungs will have to work damn hard for that and you will use far more O2 than you "create". Anyone who dives can tell you a hard draw on regulator will exhaust you rapidly. While the combination of these issues dooms success FOREVER, EACH one does as well. Not hough water contact, not enough O2 concentration to make a difference, not enough gas mass to fill the lungs, ...... TOTAL FRAUD"
