FWIW, I want one of these so bad I can taste it but it ain't gonna happen anytime in the forseeable future.

37 kg. Ouch. That is not a travel friendly unit. Any specific reason why it is this heavy (heavy frame, housing, tanks, ... all of them very heavy)? What about the weight without tanks? As a comparison, the Evolution without tanks is 18 KG.

Dunno about the other components. What I do know is the PST 45 cf LP steel tanks are almost 20 lbs each. Subtract that and you are at about +/- 16 kg.

Thats a lot of gas for an eCCR, isn't it? I've been trying to work out what kinds of profiles you could do using just the diluent tank as bailout and the O2 tank for deco (i.e. no slung cylinders).

These 27 cu.ft. bottles, what is the metric equivalent? 4 litres?

 

[StSomewhere]

27 cf = 4.3 liters.

Remember: my unit is a prototype w/ metal back plate/frame and 30cf tanks @2640 psi (27cf @2400 psi).
On the production units will be ABS and you will travel w/o tanks that means; will be lighter then Evolution plus is compact and user friendly (unit and eletronics).

Where did "27 cu.ft." tanks come from? 45 cu.ft. is enormous for a recreational CCR - over 6 litres, compared with the Inspiration's 3 litres. Can't imagine why they should be so big, as short of a big problem (with equipment or diver) they'll way outlast the scrubber.
