Walking around the opening night of the ARPA-E technology showcase is like getting to peek into a window onto some of the most interesting energy-focused labs across the U.S. — from the corporate R&D efforts of GM and Johnson Controls to government-backed labs to the occasional venture-backed startup. It’s also about as geeky as looking straight into a lab window; much of these groups don’t have commercial products yet and have little or no marketing and branding (but I guess you don’t need slick branding if you’re selling a membrane to an industrial conglomerate).
Here’s my photos from walking around the event:
