US, Russia, and China are developing next generation nuclear submarine fleets, other countries are also mastering nuclear submarine technology

UK Nuclear Submarine

A nuclear submarine is a submarine powered by a nuclear reactor. The performance advantages of nuclear submarines over “conventional” (typically diesel-electric) submarines are considerable. Nuclear submarines are more powerful than diesel-powered submarines because nuclear reactors powering them can run for…...

New materials bringing Thermoelectric generators or heat-to-power technology close to deployment

IoTsurveiilance

Thermoelectric energy harvesting mainly depends on the operation of the thermoelectric generator (TEG). A thermoelectric (TE) device can directly convert heat emanating from the Sun, radioisotopes, automobiles, industrial sectors, or even the human body to electricity.  A TEG converts heat…...
