Sepp Hasslberger: A Fuel Cell That Cleans Water and Makes Electricity—Simultaneously

A Fuel Cell That Cleans Water and Makes Electricity—Simultaneously A new design devised by a team of Penn State graduate researchers opens up a future of sustainable wastewater treatment. The same kinds of bacteria used in wastewater treatment plants can also generate small amounts of electricity. But these two abilities have rarely been combined so …

Sepp Hasslberger: Nanotrees Harvest Sun Energy to Convert Water into Hydrogen Fuel

Nanotrees harvest the sun’s energy to turn water into hydrogen fuel (PhysOrg.com) — University of California, San Diego electrical engineers are building a forest of tiny nanowire trees in order to cleanly capture solar energy without using fossil fuels and harvest it for hydrogen fuel generation. Reporting in the journal Nanoscale, the team said nanowires, …
