Photos 1/6 Tidal Energy Innovation ARPA-E’s OPEN 2012 program awardee Brown University and partner BluSource Energy took a novel approach to converting the steady, reliable flow of rising and falling tides into electricity. Instead of a traditional rotary-type turbine, the Leading Edge technology harvests the energy of the sea using an “oscillating hydrofoil.” Photo courtesy of Photo courtesy of ARPA-E. 2/6 Roving Comforter The ARPA-E University of Maryland team's RoCo, one of the world’s first personal air conditioning systems. Developed as part of the DELTA program, this portable system uses a “smart” nozzle to track users’ movements and direct cool or warm air where needed.

Here, ARPA-E Fellow Dr. Addison Killean Stark delivers his fast pitch on “High-Temperature Waste Heat Utilization: Towards Flame-Temperature Topping Cycles.” Photo courtesy of Photo courtesy of ARPA-E. 4/6 Tech Terps The ARPA-E University of Maryland project team exhibits their technology at the 2017 ARPA-E Energy Innovation Summit.

Awardees Purdue University and IBM demoed PhenoRover -- a semi-automated, mobile sensor platform -- at the 2017 ARPA-E Summit. This high-tech tractor has an impressive array of onboard sensing equipment that lets it quickly scan and sample entire fields of sorghum in search of the very best plants for breeding next-generation biofuel crops.
