Using aluminum to store energy

1) Metallic aluminium is produced with renewable electricity from alumina (Al2O3) by a carbon-free smelting process and stored without energy losses for months (Power-to-Alu). 2) In an Alu-to-Energy converter unit, aluminium reacts with water to generate heat, hydrogen and oxidized aluminium.

Turning off the thyristor using a tank circuit

When connected to a direct current DC supply, the thyristor can be used as a DC switch to control larger DC currents and loads. When using the Thyristor as a switch it behaves like an electronic latch because on. So we must reduce the anode current below the thyristor holding current Ih. That is the only way to turn it off. In our circuit this job is done by the normally closed off push button shown as S2. So when we press S2 then it opens the circuit and cuts current flow to zero.What is a thyristor firing circuit?YouTube [pdf]

Bismuth ferrite thin film solar container

In this study, a facile chemical approach was utilized to successfully fabricate a porous bismuth ferrite (BiFeO3, BFO)/reduced graphene oxide (rGO) nanocomposite thin film as a photoanode for photoele. [pdf]

The ultimate direction of solar container

In the Northern Hemisphere, panels facing true south (azimuth angle 0°) receive the highest solar radiation throughout the year. This direction ensures sustained sunlight exposure during peak hours, maximizing energy production. Deviating 30° from true south may reduce power output by 10%–15%; [pdf]
