Imagine being able to use electricity to power your car — even if it’s not an electric vehicle. Researchers at the UCLA Henry Samueli School of Engineering and Applied Science have for the first time demonstrated a method for converting carbon dioxide into liquid fuel isobutanol using electricity.
Scientists today described a new and more efficient version of an innovative device the size of a home washing machine that uses bacteria growing in municipal sewage to make electricity and clean up the sewage at the same time.
Bacteria can produce hydrogen from biomass but they take their time. In a new European project (HyTIME), nine partners including universities, knowledge centres and industry will examine ways to increase the hydrogen production rate during the next three years.
Researchers at The University of Texas at Dallas and Virginia Tech have created an undersea vehicle inspired by the common jellyfish that runs on renewable energy and could be used in ocean rescue and surveillance missions.
Hydrogen fuel cells, like those found in some “green” vehicles, have a lot of promise as an alternative fuel source, but making them practical on a large scale requires them to be more efficient and cost effective.
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.
An Indian scientist, the Director of Center for Development of Physics Education from Rajasthan University, Prof Y.K. Vijay has recently developed an affordable technique to boost the fuel efficiency of usual cars.
