We’ve written before about Mosaic, the California-based company that acts as a Kickstarter for solar-power projects. They’ve already raised more $5.6 million for solar projects across the country. But every little bit counts, and the minimum investment in a project is just $25.

Now, just as you’re wracking your brains for what to get your weird hippie uncle, Treehugger reports that that the company’s about to start offering “gift cards for the $25 incentive that can be used as stocking stuffers.” HINT HINT HINT.

Seriously, we’re always saying around the holidays that we don’t need more stuff. Here’s a simple way to put that principle into action.
