Study shows how to power California with wind, water and sun
Imagine a smog-free Los Angeles, where electric cars ply silent freeways, solar panels blanket rooftops and power plants run on heat from beneath the earth, from howling winds and from the blazing desert sun.
New approach to form non-equilibrium structures
Although most natural and synthetic processes prefer to settle into equilibrium—a state of unchanging balance without potential or energy—it is within the realm of non-equilibrium conditions where new possibilities lie. ...
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 smart wristband for nocturnal cyclists
Five EPFL PhD students have developed a wristband that flashes when the rider reaches out to indicate a turn. Their invention was recognized at a European competition.
