Pacific Gas and Electric said it may soon implement another round of Public Safety Power Shutoffs due to forecast high winds.
The latest shutoff would impact about 96,191 customers in 16 counties.
Transmit Electricity wirelessly and surprise everyone. Make your own Tesla tower to transmit power wireless. The tower uses a tesla coil that is based on the concept of Electromagnetic force and resonance to transmit energy.
However, it doesn’t actually transmit electricity, all it does is excite the electrons on the walls of fluorescent or neon lights to make them glow.

Radar and LiDAR have been incredibly quick and effective tools for mapping and surveying the Earth’s surface from aircraft and satellites, but while they can deliver accurate readings through cloud and even forest canopy cover, they can’t tell you what’s below the surface of the sea. Seawater absorbs far too much of the signal.
Sonar remains the most effective way to map out the sea floor – but the vast majority of the oceans that form 70 percent of the Earth’s surface remain unmapped, because sonic waves have hitherto only been able to be sent out from underwater. Sound waves sent from air into water lose more than 99.9 percent of their energy in the translation; it’s why the outside world goes so wonderfully silent when you dive down to the bottom of the pool. The meagre remaining 0.1 percent of the energy does create a sonar signal, but that loses a further 99.9 percent of its energy upon coming back up from the water into the air.

The oxygen evolution reaction (OER) is a chemical process that leads to the generation of molecular oxygen. This reaction is of key importance for the development of clean energy technologies, including water electrolyzers, regenerative fuel cells and rechargeable metal-air batteries.
The extent to which this reaction occurs has so far been limited in many materials, which has restricted the conversion efficiency of some types of energy technologies. Materials scientists have thus been trying to identify alternative materials, including metals, metal oxides and hydroxides, that could be used as electrocatalysts to fuel this reaction. The materials identified so far, however, are far from ideal for large-scale implementation, as they are either not particularly resistant or too expensive.
A class of materials widely investigated as possible electrocatalysts for the OER are metal-organic frameworks (MOFs), hybrid and crystalline compounds that consist of a regular array of positively charged metal ions surrounded by organic molecules. While these materials have promising catalytic properties, scientists have yet to identify optimal strategies to enhance their performance.
The Tasmania government has declared that it has become the first Australian state, and one of just a handful of jurisdictions worldwide, to be powered entirely by renewable electricity.
In a statement released on Friday, Tasmanian energy minister Guy Barnett said that state had effectively become entirely self-sufficient for supplies of renewable electricity, supplied by the state’s wind and hydroelectricity projects.
“We have reached 100 per cent thanks to our commitment to realising Tasmania’s renewable energy potential through our nation-leading energy policies and making Tasmania attractive for industry investment, which in turn is creating jobs across the State, particularly in our regions,” Barnett said.

VTOL (vertical take-off and landing) drones are quite versatile, as they combine the vertical flight of a helicopter with the fast and efficient forward flight of a fixed-wing airplane. This one features an extended range, thanks to a fuel cell power system.
The experimental aircraft was developed by a team at the Netherlands’ Delft University of Technology (TU Delft), working with colleagues from the Royal Netherlands Navy and the Netherlands Coastguard. It has a 3-meter wingspan (9.8 ft), weighs 13 kg (29 lb), and features 12 motor/propeller units distributed on its two wings. Even if several of the motors fail, it can reportedly still fly and land successfully.
