VW and Toyota are interested in high-tech covers that can keep cars cool


Automakers, especially in this new era of EVs, almost always try to save energy. But dumping energy can actually be ideal in the right situation and a company called Solcold is working to do that.

The Israeli startup is working on a component that uses anti-Stokes fluorescence to reflect heat from the sun and keep people away from cars (or any other object that people don’t want too hot, such as buildings, silos and others).

The technology has attracted the interest of major automakers such as Toyota and Volkswagen, who recently participated in a demonstration of the effects of the Polo proprietary coating, which can be applied to cars as a wrapper.

To prove its effectiveness, Solcold took three white hatchbacks on a sunny day, one with its components above and two without. The first polo without the Solcold rose to 55 ° C (131 ° F), whereas with it the car rose to only 37 ° C (98 ° F) in full sun. It’s still toasty but it’s a significant improvement over the control car.

Which is really impressive, though, because the third car, which had no cover but was parked under a parasol to provide shade, had a cabin temperature of 40 ° C (104 ° F). This means that the Solcold coating, in this exhibition, was actually more effective than the shade in keeping a car cool.

Speaking to Drive, Salkold said that depending on the size of a car’s cabin, its component temperature can be reduced by 20 to 70 percent. This will reduce a lot of pressure from the A / C unit to cool a car and can save a life if a child or pet is left in the car as the manufacturer mentioned.

How it does this remains a matter of some privacy, but the basic idea is that the material uses multi-level construction. The middle layers absorb energy from the sun and transmit it at higher frequencies. The bottom layer, meanwhile, reflects light without absorbing and to shut down the system, there is a top layer, although what it does is strictly confidential. Finally, the bottom of the casing has the cooling effect of the car.

The materials used in Solcold are not toxic and do not contain rare earth ingredients, the company says. The reflected energy will not surprise the pedestrians (or the occupants of the apartment above), due to the design of the nanostructures, which emit light.

Currently at the prototype stage, Solcold could be ready for production later this year. It will then be used in a Volkswagen concept car and, if it works and is affordable, can make it into a production car.
