Opinion: Reinventing fuel-based power for a more secure and resilient grid

Green Car Congress

As our world becomes more connected, more electrified, and more renewable, not only are we increasing the demand on our energy systems, but we are also fundamentally changing the way they operate. Increasingly, wind and solar are replacing fossil fuels as our principle source of energy. 100% wind and solar is not feasible on its own.

GKN to supply 500 electric flywheel hybrid drive systems to Go-Ahead Group for buses

Green Car Congress

Useable stored energy is 1.2MJ, with peak power of 120kW. The Mk4 eFES has a separate inverter so that the flywheel and inverter combination connect directly to the vehicle’s DC bus. The GKN Hybrid Power Mk4 eFES is an electrically driven flywheel energy storage system. The motor is a three-phase permanent magnet motor. Earlier post.).

Solar and Battery Companies Rattle Utility Powerhouses

Cars That Think

It's being marketed as the " Tesla Energy Plan ," and is available to any individual household in this region of 24 million people that has a solar panel system, a grid connection—and a Tesla powerwall, the Palo Alto firm's gigafactory-made 13.5 kWh battery wall unit. For bigger national grids it gets more complicated.

V-2 rockets it used to rain destruction on London. A second wire also wrapped around the core forms a control winding. The control winding includes many turns of wire, so by passing a relatively small direct current through it, the iron core can be forced into or out of saturation. How Magnetic Amplifiers Amplify.

Inside the Global Race to Tap Potent Offshore Wind

Cars That Think

One day soon, a platform 50 times as large may float in the deep waters of the North Sea, buoying up a massive wind turbine to harvest the steady, strong breezes there. About an hour’s ride up the coast, full-scale 3,000-tonne behemoths already float in Aberdeen Bay, capturing enough wind energy to electrify nearly 35,000 Scottish households.

Robert Kahn: The Great Interconnector

Cars That Think

The ARPANET Is Born Kahn wasn’t the only one thinking about connecting disparate computers in the 1960s. In 1965, Larry Roberts, then at the MIT Lincoln Laboratory , connected one computer in Massachusetts to another in California over a telephone line. There were 30 or 40 nodes on the ARPANET at the time.
