“Stella” is the name on every climate-cautious, pollution-loathing environmentalist’s lips.

Who is Stella? Well, she’s a car.

She may not be “pretty” by conventional standards, but Stella is the first family car powered by solar energy. The car – driven by a team of students from Eindhoven University of Technology – has just finished its road trip from Los Angeles to San Francisco, fueled solely by the California sunshine.

While the car is capable of traveling 500 miles (800km) on a single charge and can clock up to 80 miles per hour, there is still one pressing question on everyone’s mind – who will drive it?

“Do you want it in your daily life? Would you want to take it to get groceries?” asked one of Stella’s drivers, Jordy de Renet, in an interview with Popular Science.

The car’s strange shape stems from a compromise for aerodynamics and allowing comfort for at least two people. Also, the wedge-shaped vehicle’s flat surface allows for more solar cell coverage.

This from Popular Science:

Stella is CO2-neutral and the first energy-positive car in the world. The solar array charges while the car is in motion as well as when it is parked. “We get more energy out of the car than is needed to drive it,” said de Renet. That power, as much as twice what the car uses, can be returned to the grid.

A team of researchers at Michigan State University has developed a new type of solar concentrator that can harvest energy when placed over a window without blocking the view.

The new development is called the transparent luminescent solar concentrator and it has the potential to be used on buildings, cell phones, and any other device that has a flat, clear surface.

This from Science Daily:

Research in the production of energy from solar cells placed around luminescent plastic-like materials is not new. These past efforts, however, have yielded poor results – the energy production was inefficient and the materials were highly colored.

The transparent luminescent solar concentrator is still in the beginning of its development – yielding a solar conversion efficiency just close to one percent. However, Richard Lunt of MSU’s College of Engineering believes the concentrator will reach efficiencies beyond five percent when fully optimized.

“It opens a lot of area to deploy solar energy in a non-intrusive way,” Lunt said. “It can be used on tall buildings with lots of windows or any kind of mobile device that demands high aesthetic quality like a phone or e-reader. Ultimately we want to make solar harvesting surfaces that you do not even know are there.”

ECS will have a symposium at the upcoming meeting in Cancun dealing with solar fuels and the utilization of solar energy. Find out more about the meeting and sign-up for early bird registration today!
