A thermophotovoltaic (TPV) cell (size 1 cm x 1 cm) mounted on a heat sink designed to measure the TPV cell efficiency. To measure the efficiency, the cell is exposed to an emitter and simultaneous measurements of electric power and heat flow through the device are taken. Image: Felice Frankel
A heat engine with no moving parts converts heat to electricity with over 40 percent efficiency
None of these marine energy devices are commercially available—yet. With help from an updated data collection and processing tool, Americans could soon get clean energy from waves, tides, and river and ocean currents. Photo from the U.S. Department of Energy
Is marine energy finally here?
Texas A&M AgriLife Research scientists are using artificial intelligence for producing algae as a reliable, economic source for biofuel. This illustration depicts integration of machine learning-informed semi-continuous algal cultivation (SAC) and aggregation-based sedimentation (ABS) for biofuel production.
