The idea is really wonderful. It again proves that we are amidst energy. The same can be made use of for communications as well. Shall try it. it is not limited to 50 Hz. can be any thing that a sensor can detect. Santosh Kumar Kakulapati santkakul@gmail.com

I can see an instant benefit to using general lighting as a means to communicate, which is that privacy would not be a concern, since there would be no privacy. The challenge will be to add data transmission to the already challenging controllers that will be needed for efficient and reliable lighting fixtures. So it is indeed an interesting concept, and it sounds like somebody with a product to sell will be very busy attempting to convince people that they want this product. Another case of "a solution seeking urgently for a problem". Also, the large projected market sounds like an attempt to convince investors to buy yhe company stock. Have we seen that before?

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.
