No, it has to be less efficient...wireless radiates in many directions (even if you use resonance like in this case), you have to be a right place with teh reight surrounding for an optimum energy transfer...it is more effcient with wrires for sure, the only question is by how much...Kris
Thank you Mark for pointing this out, here is the link for others to enjoy:
I need to point out the obvious though: the energy used for charging wirelessly those EV cars will have to come from somewhere! so saying "moving beyond oil, fossil and radioactive fuels" is a bit premature to say at least...Kris
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
