for the past three years, our friend, german architect andré broessel of rawlemon has developed efficient concentrated solar energy systems. his previous endeavour, the ‘betaray spherical glass solar energy generator’, implemented a glass ball lens into its design for improving energy efficiency by up to 35% over traditional PV panels. building on the existing technology, broessel has presented his latest stand-alone energy harvesting concept: ‘beta.ey’, a solar cell phone charger and atmospheric lamp, which is available now for funding on indigogo.

like the previous full-scale solar unit, the ‘beta.ey’ is mounted onto a micro dual axis tracking system, concentrating light from a miniature glass sphere onto the 1×1 cm multijunction cell. the unique tracking feature allows the cell to follow the sun’s path, charging the built-in 27.5 Whr battery continuously throughout the day.

with a full charge, it can power a cellphone and other devices by connecting directly to the USB 2.0 slot up to 1.5 times in 24 hours. during night, ‘beta.ey’ acts as an atmospheric lamp with a colored RGB LED light, illuminating a space without having to plug into an outlet.
