Using egg whites to to remove that can cheaply remove salt and microplastics seawater with 98+ percent efficiency
An emerging of solar energy technology, made with perovskite semiconductors, has passed the long-sought milestone of a 30-year lifetime. The Princeton Engineering researchers who designed the new device also revealed a new method for testing long-term performance, a key hurdle on the road to commercialization. Photo by Bumper DeJesus
The first perovskite solar cell with a commercially viable lifetime can perform above industry standards for around 30 years
