The brief animation of the heat exchanger in their campaign video looks very promising. It makes me curious how it was designed for conduction originally, given they announced a change to convection not too long ago. It certainly looks like a convection-centric design.
The question remains how they generate enough heat to raise the air temperature to 100°–210°C without getting the metal body hot, and then how they cool the vapor so quickly afterward. The spiral air path in the heat exchanger is really neat; maybe they have a similar pathway in the mouthpiece. Whatever they're using for insulation has to be some pretty impressive stuff for it to remain comfortable there too.
The resistance of the internals to long-term heat-related wear & tear is another thing I'm curious about. The lack of wires inside is definitely promising in that regard.
Such an intriguing little guy...
The infographic implies you can run this vape for 6 hours at temperatures up to 410f. Can we get some actual numbers? like how many bowls before the battery dies (and how many grams vaped)
I don't think the graphic suggests that at all. It says 3 hours normal use and 6 hours max. I'm guessing that involves a few variables like temperature setting and how often it's being drawn on, given it must draw more power to maintain temperature while being hit. I'm guessing 'hardcore usage' at max temp while drawing on it frequently will be closer to 2 hours battery life or less.
As for giving estimates on "how many bowls per battery", there's just too many variables involved for them to be able to give a good estimate. Moisture content of the herbs, for one thing, can significantly impact how long it takes to finish a load. Then you have the temperature setting, how often you're pulling, how fine your grind is, the amount that you've loaded, how far you like to vape your herbs...
