D'oh! I have given the game away! I was just idly speculating about green shoots in the ICO jungle. However, my earlier brain fart is quite funny when described by yourself - 'self replicating carbon recapture device' - have you patented that or is it just a trademark that is protected by copyright law for 70 years?

Other words - 'windfall'. 'Guaranteed windfall every autumn!' 'Growth'. Really all the metaphors for business things work humorously - 'short selling'...
