Electric Sky wins DARPA grant to work on focused power beaming system for drones

Posted by in categories: business, drones, energy

Electric Sky says it’s begun building its first transmitter for providing tightly focused wireless power to drones in flight, thanks to funding from DARPA.


A startup called Electric Sky says it’s begun building its first Whisper Beam transmitter for providing tightly focused wireless power to drones in flight, thanks to a $225,000 award from the Defense Advanced Research Projects Agency.

Electric Sky will use the six-month Phase I award, granted through DARPA’s Small Business Innovation Research program, to explore ways to adapt its wireless architecture to power a swarm of drones.

Carbon Zero 2030. They Claim The Energy Supply Cannot Be Done. They Are Wrong!

Posted by in categories: energy, futurism

It is true that renewables have an immense road ahead, but we already know the destination, Net Zero, in all areas of life, so why keep throwing good money after bad with fossil fuels.

I show exactly where we are with renewables and storage, and indeed it is woefully short, but I also show how we could take the initiative and the right decisions to clean our energy supply as early as 2030.

Neoen reveals plans for another 300MW big battery in South Australia

Posted by in categories: energy, sustainability

Neoen reveals plans for another big battery in South Australia which could be even bigger than the Victorian Big Battery opened on Wednesday.


French renewable energy and battery storage developer Neoen, fresh from the formal opening of the Victorian Big Battery – the biggest in Australia to date – has revealed plans for a potentially even bigger battery in South Australia.

Neoen is due to hold a community open day on Thursday for the Blyth battery, which will be sized up to 300MW and 800MWh, trumping the 300MW/450MWh capacity of the newly opened VBB near Geelong.

Phase 3 of the world’s largest offshore wind farm moves forward

Posted by in category: energy

British utility SSE and Norwegian energy giant Equinor announced late last week that they have secured financing to proceed with the construction of the $3.98 billion Dogger Bank C offshore wind farm off England’s northeast coast.

Dogger Bank C offshore wind farm, along with Dogger Bank A and Dogger Bank B, is due to become the largest offshore wind farm in the world upon completion, with an installed capacity of 3.6 gigawatts (GW). Each phase is 1.2 GW.

Dogger Bank C will generate around 6,000 gigawatt hours (GWh) of electricity a year when completed in 2026.

A New Hydrogen Plane Can Fly Halfway Around the World Without Refueling

Posted by in categories: business, economics, energy, government, transportation

The FlyZero aircraft is one of a range of aircraft being designed by the FlyZero program. The new concept will store hydrogen in cryogenic fuel tanks, keeping them at a temperature of minus 250°Celsius (minus 418°Fahrenheit). Two cryogenic tanks will be placed at the rear of the plane, while two smaller “cheek” tanks will be placed near the front of the plane to keep the aircraft balanced. The mid-size aircraft will have a wingspan of 54 meters, each of which will have a turbofan engine attached.

“These designs could define the future of aerospace and aviation,” said U.K. Business Secretary Kwasi Kwarteng in the ATI’s statement. “By working with industry, we are showing that truly carbon-free flight could be possible, with hydrogen a frontrunner to replace conventional fossil fuels.”

Alinta proposes 1,000MW offshore wind farm to help power Portland smelter

Posted by in categories: energy, sustainability

Alinta unveils plans to build 1,000MW offshore wind farm near Portland to help deliver 100 per cent renewable energy supply to local aluminium smelter.


Alinta Energy is proposing a 1,000MW wind farm off the coast of Portland in Victoria that could help power the Portland aluminium smelter with up to 100 per cent renewables, and inject green energy into the country’s main grid.

The $4 billion Spinifex offshore wind project, first flagged by Alinta CEO Jeff Dimery in an interview on RenewEconomy’s weekly Energy Insiders podcast in October, would be sited about 10km off the coast of Portland.

Gaia EDR3 proper motions of Milky Way dwarfs. II: Velocities, Total Energy and Angular Momentum

Posted by in categories: energy, satellites

Abstract: Here we show that precise Gaia EDR3 proper motions have provided robust estimates of 3D velocities, angular momentum and total energy for 40 Milky Way dwarfs. The results are statistically robust and are independent of the Milky Way mass profile. Dwarfs do not behave like long-lived satellites of the Milky Way because of their excessively large velocities, angular momenta, and total energies. Comparing them to other MW halo population, we find that many are at first passage, $\le$2 Gyr ago, i.e., more recently than the passage of Sagittarius, $\sim$4–5 Gyr ago. We suggest that this is in agreement with the stellar populations of all dwarfs, for which we find that a small fraction of young stars cannot be excluded. We also find that dwarf radial velocities contribute too little to their kinetic energy when compared to satellite systems with motions only regulated by gravity, and some other mechanism must be at work such as ram pressure. The latter may have preferentially reduced radial velocities when dwarf progenitors entered the halo until they lost their gas. It could also explain why most dwarfs lie near their pericenter. We also discover a novel large scale structure perpendicular to the Milky Way disk, which is made by 20% of dwarfs orbiting or counter orbiting with the Sagittarius dwarf.
