Here’s the latest action we’re following on the GreenBeat:

MiaSolé accused of patent infringement — The solar startup has been served a patent infringement lawsuit by solar technology company Solannex. The suit alleges that MiaSolé lifted aspects of Solannex’s patented solar array interconnection structure technology after initial meetings in which Solannex’s founder demonstrated and provided samples of the technology. MiaSolé makes thin-film copper indium gallium selenide (CIGS) modules.

Nissan shows off Esflow electric sports car — The company plans to debut the car at the International Motorshow in Geneva next month. The model is a two-seat all-electric sports car that can go 150 miles on a full battery charge and can go from zero to 60 miles per hour in less than five seconds. The Esflow, pictured, has two motors that propel each of its real wheels.

Electric cars could attract rodents — While plugged into to recharge, electric car battery packs could become a magnet for nesting rodents seeking warmth, Green Car Reports writes. One automotive writer has already reported a rat causing $600 of damage by chewing through part of the wiring harness in his Chevrolet Volt test car. Since rats are considered an act of nature, the damage wasn’t covered by the Volt’s warranty.

Salazar calls for more renewables support from Congress — Department of the Interior Secretary Ken Salazar credited new permitting and financial incentives with success in boosting renewable projects but called for more support from Congress to ensure future development, Greenwire reports. As an example of the need to create more stable renewables policy, Salazar spoke of last year’s grant program largely benefitting solar and wind projects that nearly expired but were extended at the last minute for just one more year.
