Energy Harvesting

In February 2021, The US agency DARPA awarded contracts to Northrop Grumman Systems Corporation and Martin Defense Group (formerly Navatek) to build demonstration versions of the new Manta Ray unmanned underwater vehicle with an energy-harvesting system to power it indefinitely, allowing the robot submarine to carry out missions lasting months or years without returning to base or refueling.

Unmanned Underwater Vehicles UUV are also known as Autonomous Underwater vehicles AUV. They are unmanned electric craft that carry out a host of tasks from inspecting oil rigs and whale populations to sea floor prospecting for minerals.

Among the Li-ion batteries competitors, the Redox Flow Battery (RFB) system is one of the main competitors currently approaching the market.

Thursday 25 February 2021 - Solar cars and boats are now mainstream, some never plugging in. The technology of the most advanced ones is being licensed to others, a robot shuttle being next up.

The laws of thermodynamics warn us that making electricity will always be less than 100% efficient. However rapidly we transition to renewables, it is therefore a good thing that both electronic and electrical engineering hardware have been trending to the use of much less electricity.

Researchers have developed a new, low-cost wearable device that transforms the human body into a biological battery.

With more than 1TWh of battery capacity installed in the ten-year forecast and a market size of $56bn, the "Batteries for Stationary Energy Storage 2021-2031" report shows the fast-growing scale of this market, analyzing the main technologies involved in this energetic revolution.

Two hundred years ago it seemed that steel was unstoppably at the heart of transport, from rail to shipbuilding. It brought with it massive health problems, from mining the ore and coal to making the ships and railroads.
