Thermoelectric power generation

This is great news for Industrial giants whose carrying costs increase with inefficient electric power, and here?s where thermoelectric power generation will shine, because it gives office buildings efficient lighting systems. Couple that with the intelligent/smart lights, and we?ve got a power grid for the sub-500 MW category adequately furnished with energy savings.

@krisi: I think it will be efficient enough for office buildings to adopt it in many parts of the world. I don't think it will be a great option for consumer lighting purposes because it will still be carried using existing vendors and that will increase energy costs.

It should go to zero once the thermoelectric harvester warms up to the ambient temperature.

thank you Anand...what temperature difference between two ends is required?

500MW sounds very high for energy harvesting scheme...would you mind sharing your back of the envelope calculations?

Reread the article carefully: it's 500 mW (milliwatts), NOT MW (megawatts)!  Only 10e9 difference.... I have some ancient experience investigating "thermoelectric harvetsing' more than 50 years ago.  That was a study of how to exploit the ocean thermocline (temp difference between shallow and deeper water).  It's not easy, and environmental effects need to be included in the analysis.

0.5W sounds more like the number I am used to see...hardly enough to power one bulb ;-)

"Electric Bulb" category

Would like to see how this plays out as new industries are developing like LED lighting, etc. - I assume that "electric bulb" category in the above infographic is more for the Thomas Edison style than newer types.

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.
