"Gambler attempts to convert lottery ticket winnings into clean energy to minimize taxes." is fine imho. It didn't work out, but if it had, the outcome would've been "good" and he still learned a lesson and shared with the rest of us. No different than a failed startup. You win or you learn.

Oh, I am in no way judging them personally. Just do not bring that "we are doing it for the humanity" BS into what is in an essence a pure gamble.
