Hasn’t this been validated for hundreds of years? The Story of Longitude is a great read. Harrison spent decades working on the problem.

The Spirit of St. Louis crossing the Atlantic was for a prize, and I believe an inspiration for the current X-Prize.

I don’t think we need “grand challenges” but simply challenges, to help get us to successive breakthroughs.

I’ve thrown this out before, but a Kickstarter for these “challenges“, with well-defined goals might help accelerate technological progress.

Capitalism is a huge motivator by itself. Come out ahead of the competition and reap the benefits, it's a permanent contest. It's not without its downsides (externalization) but it definitely seems to move the needle.

I think some (e.g., Koch Bros) would argue that we don't really have capitalism. That (too often?) Uncle Sam steps in and unbalances the market, often in favor of current winners.

A contest, equally open to all, certainly feels like an appropriate proxy.

yes, but that doesn’t mean it’s the best solution for all problems. Investors/founders want to have their exit strategy. We get a lot of “uber of”, etc, for example.

The goal might not be a marketable solution but a step in the desired direction. I don’t know the limits of this type of prize but it’s worth pursuing:
