A new Tesla Megapack project has broken ground in Arizona, and when it comes online in 2024, it will be the state’s largest energy storage system.

For utilities, battery energy storage is one of the most helpful new technologies they can employ to reduce fossil fuel dependence and increase the reliability of their associated grid. By holding onto excess power generated during lulls in demand, power companies can more easily address peak demand and, importantly, reduce costs. Now, a new Tesla Megapack energy storage system is set to do just that in Arizona.

The Sierra Estrella energy storage facility, constructed by utility company Salt River Project (SRP) and energy system constructor Plus Power LLC, will be the largest of its kind in Arizona. The massive network of Tesla Megapacks will have a capacity of 1,000MWh, enough energy to power 56,000 homes for four hours. According to previous information released by SRP, the project was set to cost $400 million, but this does not account for the recent Tesla Megapack price cut.

Tesla is preparing to launch Powerwall 3, the third generation of its home battery pack, according to information obtained by Electrek.

In 2015, when launching its Tesla Energy division, Tesla launched the first generation of the Powerwall, and it quickly became, by far, the most popular home battery pack in the residential market.

Shortly after, Tesla launched Powerwall 2, a new version of the residential battery pack with more energy and power capacity.

Researchers have discovered that in the exotic conditions of the early universe, waves of gravity may have shaken space-time so hard that they spontaneously created radiation.

The physical concept of resonance surrounds us in everyday life. When you’re sitting on a swing and want to go higher, you naturally start pumping your legs back and forth. You very quickly find the exact right rhythm to make the swing go higher. If you go off rhythm then the swing stops going higher. This particular kind of phenomenon is known in physics as a parametric resonance.

Your legs act as an external pumping mechanism. When they match the resonant frequency of the system, in this case your body sitting on a swing, they are able to transfer energy to the system making the swing go higher.

Researchers at the Laboratory of Organic Electronics, Linköping University, have together with colleagues at the Lawrence Berkeley National Laboratory in Berkeley, California, developed a method that increases the signal strength from microbial electrochemical cells by up to twenty times. The secret is a film with an embedded bacterium: Shewanella oneidensis.

Adding to electrochemical systems is often an environmentally sensitive means to convert chemical energy to electricity. Applications include water purification, bioelectronics, biosensors, and for the harvesting and storage of energy in fuel cells. One problem that miniaturisation of the processes has encountered is that a high requires large electrodes and a large volume of liquid.

Researchers at Linköping University, together with colleagues at the Lawrence Berkeley National Laboratory in Berkeley, California, USA, have now developed a method in which they embed the electroactive Shewanella oneidensis into PEDOT: PSS, an electrically conducting polymer, on a substrate of carbon felt.

In the not too distant future, trips to the мoon will Ƅe мanned and of long duration. In order for astronauts to surʋiʋe there for the duration of their мission, they мust first find a way to create oxygen, water, and fuel with the resources that exist there, since transport froм Earth is coмpletely unfeasiƄle.

Now, a teaм of Chinese astronoмers froм Nanjing Uniʋersity has just discoʋered how to achieʋe this and thus facilitate huмan exploration to create a perмanent Ƅase.
