Meet The Popular Science #CrowdGrant Challenge Finalists

When we asked Popular Science readers to submit their biggest, boldest science and technology project ideas to the #CrowdGrant Challenge, we honestly weren’t sure what to expect.

Well, you all delivered. Big time.

Help crowdfund our finalists through Aug. 30.


Help crowdfund our finalists through Aug. 30.

Hundreds of ideas poured in from all over the world, but two dozen submissions excited us the most.

The winning projects include everything from a fusion propulsion research chamber and a handheld cancer scanner to a biological lightbulb and a better sewing needle. We even accepted a scientifically informed peace movement against mean people (because who likes mean people?).

Over the next 45 days, we’ll highlight as many individual projects — and the folks behind them — as we can. But there’s no need to wait around, because all of the winners are live and ready for your contributions through our partner, [

So what are you waiting for? Do something amazing, make history, and crowdfund the finalists that you’re excited about in exchange for cool rewards offered up by project leaders. Note: The window for contributing closes on Aug. 30 at 11:59pm EDT.

Follow the conversation or spread the word about projects on Twitter, Facebook, Google+, Pinterest, Instagram, and more.
