Crowdfunding has made so many projects possible that would otherwise not exist. It seems perfect for niche ideas, concepts that would otherwise never see the light of day, and passion projects that just need to happen. This sounds perfect for float centers, but there are some caveats. 

Crowdfunding is time intensive and there's not guarantee of success. Aside from that, there are some issues with it that complicate things for float centers that other crowdfunded projects likely won't face. Graham and Ashkahn talk about the successes of float center crowdfunding and the not-so-successes as well.
