Non-volatile memory improves energy efficiency by two orders of magnitude
Salinity-gradient-power cell's surprisingly high voltage gives it best cost-per-watt of its kind
Lockheed Martin pursues compact fusion reactor concept
Hybrid materials could smash the solar efficiency ceiling
(Phys.org) —A new method for transferring energy from organic to inorganic semiconductors could boost the efficiency of widely used inorganic solar cells.
UW fusion reactor concept could be cheaper than coal
Fusion energy almost sounds too good to be true – zero greenhouse gas emissions, no long-lived radioactive waste, a nearly unlimited fuel supply.
Radio telescopes unravel mystery of nova gamma rays
Highly-detailed radio-telescope images have pinpointed the locations where a stellar explosion called a nova emitted gamma rays, the most energetic form of electromagnetic waves. The discovery revealed a ...
How to make a "perfect" solar absorber
The key to creating a material that would be ideal for converting solar energy to heat is tuning the material's spectrum of absorption just right: It should absorb virtually all wavelengths of light that ...
Harvesting hydrogen fuel from the Sun using Earth-abundant materials
The race is on to optimize solar energy's performance. More efficient silicon photovoltaic panels, dye-sensitized solar cells, concentrated cells and thermodynamic solar plants all pursue the same goal: to ...
New 'topological insulator' could lead to superfast computers
University of Utah engineers discovered a way to create a special material – a metal layer on top of a silicon semiconductor – that could lead to cost-effective, superfast computers that perform lightning-fast ...
Improved liquid battery: Longer-lasting materials could enable batteries that make renewables more competitive
Researchers at MIT have improved a proposed liquid battery system that could enable renewable energy sources to compete with conventional power plants.
A promising light source for optoelectronic chips can be tuned to different frequencies
Chips that use light, rather than electricity, to move data would consume much less power—and energy efficiency is a growing concern as chips' transistor counts rise.
Study sheds new light on why batteries go bad
A comprehensive look at how tiny particles in a lithium ion battery electrode behave shows that rapid-charging the battery and using it to do high-power, rapidly draining work may not be as damaging as researchers ...
Scientists create renewable fossil fuel alternative using bacteria
The development is a step towards commercial production of a source of fuel that could one day provide an alternative to fossil fuels.
Superabsorbing ring could make light work of snaps
A quantum effect in which excited atoms team up to emit an enhanced pulse of light can be turned on its head to create 'superabsorbing' systems to make the 'ultimate camera pixel'.
