A new device that’s powered by sunlight could help solve water scarcity problems.

Paint these days is becoming much more than it used to be. Already researchers have developed photovoltaic paint, which can be used to make “paint-on solar cells” that capture the sun’s energy and turn it into electricity. Now in a new study, researchers have created thermoelectric paint, which captures the waste heat from hot painted surfaces and converts it into electrical energy.

“I expect that the thermoelectric painting technique can be applied to waste heat recovery from large-scale heat source surfaces, such as buildings, cars, and ship vessels,” Jae Sung Son, a coauthor of the study and researcher at the Ulsan National Institute of Science and Technology (UNIST), told Phys.org.

“For example, the temperature of a building’s roof and walls increases to more than 50 °C in the summer,” he said. “If we apply thermoelectric paint on the walls, we can convert huge amounts of waste heat into electrical energy.”

Elon Musk finally unveils the long-awaited electric car for the masses.

(A rendering of what X’s renewable energy storage plant would look like. X) X, the “moonshot” division of Google’s parent company Alphabet that has worked on everything from self-driving cars and delivery drones, has a new public project: storing renewable energy so it doesn’t go to waste.

The team working on the project is codenamed “Malta,” and it aims to efficiently store energy from solar and wind using salts. That way, renewable energy can still be used even if solar panels or wind turbines can’t collect energy.

Malta is part of X’s Foundry, which explores early-stage projects. It’s not an “official” project like Project Wing (drone delivery) or Project Loon (high-altitude balloons that beam the internet to the surface). X is announcing Malta now because it wants to build a prototype plant for testing how storing renewable energy can feed a power grid. It’s accepting applications for potential partners on its website.

FREMONT, Calif.—A first peek inside Tesla Inc.’s new Model 3 compact car revealed a starker, cozier interior than the more spacious and luxurious Model S. But as the sedan sped off, the experience felt similar.

On Friday, the Silicon Valley auto maker showed off details of the all-electric sedan’s interior for the first time, allowing a roughly 10-minute test ride around the factory.

The Model 3 represents a milestone for…

A batch of single-cell protein has been produced by using electricity and carbon dioxide in a joint study by the Lappeenranta University of Technology (LUT) and VTT Technical Research Centre of Finland. Protein produced in this way can be further developed for use as food and animal feed. The method releases food production from restrictions related to the environment. The protein can be produced anywhere renewable energy, such as solar energy, is available.” In practice, all the raw materials are available from the air. In the future, the technology can be transported to, for instance, deserts and other areas facing famine.

Range anxiety be gone.

30 lucky customers will get their hands on the first Tesla Model 3 electric cars to roll off the production line. Here’s why it matters.
