I am invested in this company called PLUG and BMW uses their hydrogen powered fuel cells to operate almost all of their machinery (same with walmart, and other large names).
Today BMW just completed a project that harvests hydrogen gas from landfills that power their machinery (fuel cells)! I'm sure a lot of you guys are only ehre for the cars, but I thought this was a really cool accomplishment and wanted to share!
