Record breaking: Solar Frontier pushes CIS thin-film efficiency to 19.7%
Solar Frontier has broken the record for CIS thin-film solar cell conversion efficiency using a sputtering and selenization process. The current CIS efficiency record at 20.3% was set with the co-evaporation processes.

Resilient Technologies, a Wisconsin based company, has created a tire that can’t go flat.
Instead of using a pressurized air cavity, the tire design relies on a geometric pattern of six-sided cells that are arranged in a matrix like a honeycomb.
It has the same ride, reduced noise levels and heat generation as pressurized tires. The goal was to create an airless tire with uniform flexibility and load transfer that would endure tremendous wear and tear and still perform well.
The best design was found in nature, which was the honeycomb.
