Sorry Max. I do bow to your superior knowledge. I should have clarified, and do so later in the piece, and Tesla acknowledges in his patent, that most of the energy input will come from steam or compressed air. What I should ahve made clear is that the generator might use 1kW for excitation - ie field coils - from a 10KW output. Not to be confused with the excitation in the plans, which is a spark gap intended to get non-technical viewers excited I think!
@David: You say "Maybe Tesla did produce a generator that gave 10KW output for a 1KW excitation input, giving it 90% efficiency electricity wise..."
Hang on, 90% efficient? If you put 10 in and get 1 out, you are 1/10 = 10% efficient, so if you put 1 in and get 10 out, that means you are 10X or 1000% efficient (which is pretty damned efficient, let me tell you -- I R an Engineer and I know these things :-)
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.
