A solar-driven photoelectrochemical cell provides a promising approach to enable the large-scale conversion and storage of solar energy, but requires the use of Earth-abundant materials.
Well, science could well be on its way to making us float too, thanks to a breakthrough in sonic levitation. Engineers from the University of Bristol have demonstrated that it’s possible to trap (essentially levitate) objects larger than the wavelength of sound in an acoustic tractor beam
The Yanmar Dtorque 111 is lighter and more compact than petrol engines of similar capacity, has double the engine life, is much smoother, offers much better fuel consumption and running costs, produces significantly less toxic emissions, here is a chance to push diesel engines into use in polluted areas
