Energy Focus Inc. delivered a 42.8 efficiency solar cell as part of the Very High Efficiency Solar Cell consortium (VHESC). The company contributed this development as part of the federal government's Defense Advance Research Projects Agency (DARPA) contract. The highly efficient VHESC solar cell uses a novel lateral optical concentrating system that splits sunlight into three different energy bins in order to optimize absorption and conversion. The stationary VHESC optical system is capable of absorbing large amounts of light without using a complicated tracking device.
When you think of the DARPA Robotics Challenge, you may imagine complex humanoid contraptions made of metal and wires that move like a Terminator Series T-90. But what actually happened at the much-vaunted event was something just a bit different.
Traditional dev kits are based on a manufacturer’s microcontroller, radio module, or sensor device. The idea is to aid the design engineer in developing his or her own IoT prototype as quickly as possible. A not-so-traditional IoT development kit released by Bosch aims to simplify IoT prototyping even further.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
