That's the blind, the bet required to play, in aerospace, it's not a lot of money at all by their standards.

Or by social media standards. I know it's a rather over-used meme now, but I'm again reminded of Instagram's $1b buyout vs. this.

This seems like a good blue-sky venture for a scientific philanthropist. There's a lot that could go wrong, it might not work (though as pointed out elsewhere, this isn't all theory - they have tested the heat exchanger in real life on a proper jet engine), but it could be a big win. If only someone like Gates could put down $400m for a chance of a big pay off later.

That would be the ante - a forced bet affecting all players. Blinds are typically only posted by one or two players.
