While this article does explain quite a bit, it is clear that the impact of the several loss mechanisms is not brought out to any extent. Wireless transmission of energy for recharging portable devices will not be the most efficient way ever, it is clear. Of course the fact that it wastes a lot more power will not take away from the "cool factor", nor will it negate the convenience of not needing to pay attention to what one is doing when connecting a charger. In addition, the marketing weasels are very hot to make this the "next big thing" in product differentiation. What would have made much more sense would have been a standard charging connector for all cell phones, with different sizes for the different voltages, but with all brands being forced to use the standard charging connector. Then everybody would have had the same burden, and none of the manufacturers could claim that others had an advantage. Of course, it is too late for that to happen now, but perhaps the industry could learn.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
