That means that low-temperature waste heat can be used to produce high-quality chemical energy hydrogen for the first time.

In the meantime, Weather Channel has used a simpler measure, called "feels like, " to express temperature in a temperature-like number, taking into account wind chill at low temperatures and humidity at high temperatures.

At this temperature, the mirror was able to flip between high and low reflectivity over a million times a second suggesting that, if it can be kept reliably at this critical temperature, gallium will make a fast (and also small and cheap) optical switch.

It meets the highest standards of resistance to dust, sand, shock, vibrations, low pressure, high and low temperature, rain and long-term moisture.

Essentially, he says that a dramatic temperature peak will be reached in years measured in high tens to low hundreds, and that the cooling period following will take anywhere from 100, 000 to 500, 000 years, depending on what we humans do right now and in the next decade about carbon emissions.

Analysis in the 70s and 80s variously suggested that high pressure, high temperature and low humidity were associated with positive emotions - basically, nice weather seemed to put people in a good mood.
