Can you control your whole body's temperature by heating or cooling just one small part of it? It seems a little far-fetched, but the makers of the Aircon Watch certainly believe you can, and if their early crowdfunding success in anything to go by, they are far from alone.

Over the last few years a Stanford team has been developing a roof-mounted system that cools a building by reflecting heat into space, and the latest test has managed to use solar panel-like devices to cool water without needing any other energy source.

Data centers chew through a huge amount of power, thanks largely to the cooling. To help fight that on both fronts, the world’s largest data center is set to be built in Norway, making use of the chilly Arctic climate to keep the servers cool while drawing all of its power from renewable sources.

Google’s parent company, Alphabet, has now spawned Dandelion, a new startup that aims to tap into geothermal energy. The company’s signature technology is a geothermal heating and cooling system that pumps heat from the ground into the home in winter, or out of it during summer.

Two years ago we wrote about the $450 Mistbox, a device that reduces air conditioning electricity bills by 30 percent. Mistbox has since been revised and a near identical product is now available for an annual $100 fee (or $10 a month) with no up-front costs.

The next big breakthrough for electronics is likely to be quantum computers, but there are still plenty of hurdles to jump before they become a reality. A team from Aalto University in Finland may have cleared one of those obstacles, developing a “nanorefrigerator” to help cool components down.

Electronics don't work well in heat, which is a problem because heat is a byproduct of electricity. Researchers have developed a thermal diode that runs on heat instead of electricity. This could lead to heat-resistant computers that function in hot places like on Venus or deep inside the Earth.

One down side to CubeSat satellites' small size is the fact that they can overheat or get too cold very quickly. With that in mind, scientists have created a new type of temperature-regulating radiator for them … and it does its job by folding, just like origami.

The days of the rackety, energy-gobbling refrigerator may be numbered with the advent of more efficient systems that cool with the use of magnets. Cooltech Applications has launched the first magnetic refrigeration system (MRS) for commercial use.

Scientists have discovered a new way to finely control how much heat and steam is released in the process of boiling water, a technique they say could lead to advanced cooling systems for more efficient electronic devices.
