Engineered for tolerance, bacteria pump out higher quantity of renewable gasoline
An international team of bioengineers has boosted the ability of bacteria to produce isopentenol, a compound with desirable gasoline properties. The finding, published in mBio, the online open-access journa ...
Optimum inertial self-propulsion design for snowman-like nanorobot
Scale plays a major role in locomotion. Swimming microorganisms, such as bacteria and spermatozoa, are subjected to relatively small inertial forces compared to the viscous forces exerted by the surrounding fluid. Such low-level ...
A win-win-win solution for biofuel, climate, and biodiversity
Fossil fuel emissions release billions of tons of carbon into the atmosphere each year, which is changing the climate and threatening the sustainability of life on planet Earth. In Brazil, the demand for ...
GE has surgical technique to power up wind blades
Student research leads to method for developing clean hydrogen fuel
(Phys.org) —Recycling waste materials into new products is a common method for sustaining a green environment, but it isn't only limited to reusing old cans, plastics, and paper. In chemistry, scientists ...
SustainX builds 1.5 MW isotherm compressed air energy storage system
Stanford researchers say 'peak oil' concerns should ease
Fears of depleting the Earth's supply of oil are unwarranted, according to new research, which concludes that the demand for oil – as opposed to the supply – will reach its own peak and then decline.
Britain's London Array is world's biggest offshore wind farm
Student's flashlight works by body heat, not batteries
A designer enzyme for alternative energy
(Phys.org) —Imagine pulling energy out of thin air. Yi Lu and his colleagues are on that path, in a quest to find alternatives to fossil fuels. The team has designed an enzyme that can harvest the energy ...
Electric cars slow to gain traction in Germany
Germany plans to have one million electric vehicles on its roads by 2020, but so far that goal seems remote as the nation's motorists have shown little love for the quietly humming vehicles.
Blue ruthenium dimer catalysis for hydrogen generation
(Phys.org) —Photosynthetic water oxidation is a fundamental process in the biosphere that results in the sunlight-driven formation of O2 from water. Biological photosynthesis encompasses a series of complic ...
Petroleum use, greenhouse gas emissions of automobiles could drop 80 percent by 2050
A new National Research Council report finds that by the year 2050, the U.S. may be able to reduce petroleum consumption and greenhouse gas emissions by 80 percent for light-duty vehicles—cars and small trucks—via a combination ...
Japan researchers invent solar-cell fabric
Clothes that could literally light up your life were unveiled Tuesday by Japanese researchers who said their solar-cell fabric would eventually let wearers harvest energy on the go.
