"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.

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

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.

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

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

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

@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.

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.

what is efficiency of this thermoelectric process?

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. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.

michigan0 Sang Kim First, 28nm bulk is in volume manufacturing for several years by the major semiconductor companies but not 28nm FDSOI today yet. Why not? Simply because unlike 28nm bulk the LDD(Lightly Doped Drain) to minimize hot carrier generation can't be implemented in 28nm FDSOI. Furthermore, hot carrier reliability becomes worse with scaling, That is the major reason why 28nm FDSOI is not manufacturable today and will not be. Second, how can you suppress the leakage currents from such ultra short 7nm due to the short channel effects? How thin SOI thickness is required to prevent punch-through of un-dopped 7nm FDSOI? Possibly less than 4nm. Depositing such an ultra thin film less then 4nm filum uniformly and reliably over 12" wafers at the manufacturing line is extremely difficult or not even manufacturable. If not manufacturable, the 7nm FDSOI debate is over!Third, what happens when hot carriers are generated near the drain at normal operation of 7nm FDSOI? Electrons go to the positively biased drain with no harm but where the holes to go? The holes can't go to the substrate because of the thin BOX layer. Some holes may become trapped at the BOX layer causing Vt shift. However, the vast majority of holes drift through the the un-dopped SOI channel toward the N+Source,...
