The third rule of free energy is:"If you really find free energy, shut up about it and develop it very privately"
I reckon you'd be better off choosing life. Keep it secret until you know it works, put together a set of documents describing everything you know, then pick a date. Spam the whole thing as widely as possible as fast as possible, so there's no question that anyone will be able to grab the info and keep it secret. You'll still get your world fame and Nobel, but you won't be part of the "let's keep all of this secret" project by someone else.
Forget annoying Shell or a Saudi oil billionaire, Russia is a petro-state and Putin owns a big chunk of their oil companies. Good luck persuading him to leave you alone if you have a secret free energy source that threatens to implode him and his country.
Or, you know, make a youtube video and put it up next to "12 property investing secrets that will make you a millionaire". That can work too.
