Your Next Volvo May Be Made out of Batteries

The Swedish car company is developing a material that could be molded into body panels and double as a battery.


Here's one problem companies face when trying to build practical electric cars: Batteries are heavy. If you want to give an electric car more range, that means you need a bigger battery, which means a heavier car, which means it takes more energy to move it. It's a tricky problem.

Volvo might have a solution. The Swedish car company recently announced that it has been working with Imperial College in London to develop a "composite blend of carbon fibers and polymer resin" that can serve as a car's body panels while also functioning as a battery, storing and releasing energy. Future Volvos could be literally made out of batteries. The company's press release candidly admits that "at the moment this is just a fascinating idea," but it does add that "tests are currently under way to see if the vision can be transformed into reality."


If it can, electric cars might get a whole lot cheaper, and the same material could be used to shrink the size of anything that requires a battery: think cell phones and laptops.

Seventeen-year-old Swedish climate activist Greta Thunberg made a dramatic speech Tuesday at the World Economic Forum in Davos, Switzerland.

In her address, she called for a public and private sector divestment from fossil fuel companies

"Immediately end all fossil fuel subsidies and immediately and completely divest from fossil fuels. We don't want these things done by 2050, or 2030 or even 2021 — we want this done now," she said.

U.S. Treasury Secretary Steven Mnuchin mocked the teenager on Thursday during a press briefing in Davos.

Even though marathon running is on the decline, half a million people signed up to participate in the 2020 London Marathon. It seems wild that someone would voluntarily sign up to run 26.2 miles, but those half a million people might actually be on to something. A new study published in the Journal of the American College of Cardiology found that running a marathon can help reverse signs of aging.

Researchers at Barts and University College London looked at 138 first-time marathon runners between the ages of 21 and 69. "We wanted to look at novice athletes. We didn't include people who said they ran for more than two hours a week," Dr. Charlotte Manisty, the study's senior author and cardiologist at University College London, said per CNN.

Last Friday, GOOD reported on an infuriating incident that went down at a Massachusetts Target.

A Target manager who's come to be known as "Target Tori," was harassed by Twitter troll David Leavitt for not selling him an $89 Oral-B Pro 5000 toothbrush for a penny.

He describes himself as a "multimedia journalist who has worked for CBS, AXS, Yahoo, and others."
