Newbie with a question

[Will]

The latent heat of vaporisation of CO2 is 574kJ/kg the energy density of a typical LiPo is about 500kJ/kg - so not much to call it.
Unfortunately you need a container for the CO2, which for the relatively small amounts involved drives the density right down.

Not impossible - but probably not an advantage.

I was thinking more along the lines of maximum power output, electric motors tend to be pretty poor for mass vs peak power. it would be relatively simple to spin something up using a jet of co2 onto an fan/turbine.

Hi Will,

I am in Rochdale and currently building myself so it would be good to put heads together, especially if you need help.

Sounds good 😀
As I said I've got a lot of other things still to finish off before i start in earnest but I'm happy to help out if I'm free.
