Fuel-Cell Water Separator

NASA Glenn Research Center has designed, built, and tested an innovative fuel-cell water separator that not only removes liquid water from a fuel cell’s exhaust ports, but does so with no moving parts or other power-consuming components. The separator employs the potential and kinetic energies already present in the moving exhaust flow.

Bacteria Turns Carbon Dioxide Into Liquid Fuel

Researchers from the UCLA Henry Samueli School of Engineering and Applied Science have genetically modified a cyanobacterium to consume carbon dioxide and produce the liquid fuel isobutanol, which has great potential as a gasoline alternative. The reaction is powered directly by energy from sunlight, through photosynthesis.
