A business plan from a Ugandan for turning agri-waste into eco-friendly charcoal in rural Uganda to prevent de-forestation driven by demand for cooking fuel, an engineer who has created a reusable bag and chemical that clean contaminated water and can be distributed in disaster relief areas instead of (and much more efficiently than) bottled water, and many many more. Y’all, I wish I could fund them all.

I was blown away and my heart was brimming over with excitement that the world contains such creative, smart, passionate people. Their final video pitches aren’t online yet– I’ll post them when they are– but I thought I’d share another cool innovation I recently came across in the meantime.

Featured at the Clinton Global Initiative, The sOccket (seen above) is a soccer ball invented by four girls from Harvard that creates usable energy as it is kicked. 15 minutes of play generates 3 hours of electricity. With 25% of the world lacking electricity, there’s a huge need for innovations like this (also saw some great ones yesterday!).

The ball actually has a socket on it, so a light or cell phone charger can be plugged directly in (learned yesterday that phone charging is in huge demand in areas without electricty… crazy, huh? Phones but no electricity?). Pretty cool, eh?

The video below was created for sOccket in collaboration with American Express’s Member Project.
