Back in April, we called on Popular Science readers to submit their best project ideas in the #CrowdGrant Challenge. By the time we closed the gates for entries, two dozen stood above the rest — and 45 days of crowdfunding ensued.
Well, funding ends tonight — Friday, Aug. 30 — at 11:59pm EDT. That means only a few hours remain to make our hardworking finalists’ dreams become realities.
We’ve already seen a couple of them come true, including Project Reach for the Stars, which will send K-12 classroom experiments to the edge of space, and Consider the Facts, an effort to engage people in deliberative thinking using a story about an Earth-threatening asteroid. But nearly two dozen other cool projects have yet to hit 100 percent funding.
Here are some of the projects that are resonating the most with readers:
- Elcano – an open-source effort to make any vehicle autonomous
- Maverick Engine-Generator – a newly designed combustion engine and linear generator
- Don’t Sleep With Mean People – a scientifically informed peace movement
- Biobulb – a lightbulb powered by bacteria
- Teachers in Space – an effort to send a student project to the International Space Station
- Gravity Development Board – do-it-yourself electronics hardware rated for the harsh environment of space
- Swyboard – a device that functions both as a slender tablet and computer keyboard
- Dual-Axis Solar Tracker – an effort to turn the town of Greensburg, Kansas green with solar energy
