Rising day and night temperatures are threatening rice, wheat, and maize production by disrupting plant growth, grain filling, and grain quality, putting global food security at risk. Precision ...

These are the best whole-house heat pumps from Consumer Reports' tests. These heat pumps are more efficient and can save you money.

Spark plug heat range refers to how quickly spark plugs can transfer heat. It matters because it can affect longevity and ...

The MAN B&W 14K98ME-C engine stands as one of the most astonishing achievements in modern engineering. Imagine a mechanical heart so powerful that its total output rivals a small power station. Its ...

MIT master’s student Taylor Hampson is advancing research into nuclear thermal propulsion (NTP), thanks in part to a NASA-sponsored initiative. Nuclear propulsion could dramatically shorten travel ...

Smart home startup Quilt introduced a three-zone heat pump on Tuesday that promises to maintain efficiency even in the kinds of demanding conditions that stymie traditional incumbents. The three-zone ...

Physicists have shown that a cornerstone of thermodynamics, the Carnot efficiency limit, breaks down at the atomic scale when quantum correlations come into play. Their results suggest that ...

This has been discussed before on Ars, such as at https://arstechnica.com/civis/threa...ost-efficient-heat-pump-in-the-world.1501605/, and https://arstechnica.com ...

Not a huge percentage of our readers probably get their heat from diesel fuel, but it’s not uncommon in remote areas where other fuels are hard to come-by. If you’re in one of those areas, this latest ...

A 3D-printed Janus microchannel heat sink inspired by desert beetles enables ultrafast bubble removal and prevents CPU thermal throttling. (Nanowerk Spotlight) The Namib desert beetle survives one of ...

Scientists develop a microscopic heat engine that achieves 100% efficiency, accomplishing what seemed impossible. A new theoretical design describes a tiny heat engine that can convert all of the heat ...
