Higher plasma densities, more efficient tokamaks

When the density of the hot, ionized gas (known as a plasma) in a tokamak exceeds a certain limit, it usually leads to a rapid loss of heat and plasma currents. The currents are required to confine the plasma. Such events ...

Japan's Fukushima reactor may be reheating: operator

Temperature readings at one of the crippled Fukushima nuclear reactors have risen above Japan's stringent new safety standard but there was no immediate danger, its operator said Sunday.

Deforestation is messing with our weather and our food

Today, the National Socio-Environmental Synthesis Center (SESYNC) at the University of Maryland published new research in Nature Communications providing insight into how large-scale deforestation could impact global food ...

Heating and cooling with waste heat from industry

Heating and cooling in the future will utilise energy gained from waste heat which will be distributed at low temperature using district heating and cooling networks. It will thus make use of the heat wasted by cooling systems ...
