Dream Solar Car
California company whose name comes from the ancient Greek for “wingless,” is rolling out the first mass-produced solar car this year. It’s a three-wheel, ultra-aerodynamic electric vehicle covered in 34 square feet of solar cells. The car is so efficient that, on a clear day, those cells alone could provide enough energy to drive about 40 miles — more than twice the distance of the average American’s commute.
The Aptera must undergo safety tests before the company can begin distribution, which it hopes to do by the end of this year. Even then, it’s not clear that consumers will want to buy something that looks like a cross between the Batmobile and a beetle. The shadow of an initial attempt, which ended in bankruptcy, hangs over the founders as they gear up to launch their new product.
But the Aptera’s creators, Chris Anthony and Steve Fambro, think the world needs a car like theirs. Transportation is the largest source of planet-warming pollution in the United States. The Biden administration has made it a priority to reduce vehicle emissions, and several major automakers have pledged to phase out cars and light trucks with internal combustion engines.
After years of dreaming, maybe the time for driving on sunshine is finally here.
Solar panel power
Anthony and Fambro didn’t set out to build a vehicle that could run on solar power. They just wanted to make a more efficient car.
Burning gasoline, it turns out, is not a very efficient way to travel; as much as four-fifths of the energy produced by an internal combustion engine is lost as heat, wasted overcoming wind resistance or used up by fuel pumps and other components, according to Energy Department data.
All-electric vehicles perform much better, but they’re still not perfect. About 10 percent of the energy that goes into them is lost converting alternating current from the electrical grid into direct current for the battery. Inefficiencies in the drive system eat up another 20 percent, and the car must still deal with wind resistance and friction, through regenerative braking systems can reduce some waste.
From top to wheels, the Aptera is designed to eliminate as much waste as possible. Its creators say the car is 13 times more efficient than a gas-powered pickup truck and four times more efficient than the average electric vehicle. At least 90 percent of the power produced by the Aptera’s solar panels goes toward making the vehicle move, the company says.
