Tesla's Massive Australian Battery Responds to Coal Power Outages in Milliseconds
The system—the largest of its kind on planet Earth—was tested twice just this month. According to CleanTechnica, on Dec. 14, the Loy Yang coal power plant in the neighboring state of Victoria suddenly went offline. Remarkably, the Hornsdale Power Reserve battery system (the Tesla system's official name) kicked in within 140 milliseconds and injected 100 megawatts of power into the grid.
Two weeks later, another unit of the Loy Yang plant unexpectedly went offline. Tesla battery's also responded within milliseconds to send 16 megawatts to the grid.
“That's a record and the national operators were shocked at how quickly and efficiently the battery was able to deliver this type of energy into the market," State energy minister Tom Koutsantonis commented after the Dec. 14 outage. “Until now, if we got a call to turn on our emergency generators it would take us 10 to 15 minutes to get them fired up and operating which is a record time compared to other generators."
The 100-megawatt Powerpack system, which charges using renewable energy from Neoen's Hornsdale wind farm near Jamestown, is designed to hold enough power for 8,000 homes for 24 hours, or more than 30,000 houses for an hour during a blackout.
Tesla CEO Elon Musk famously made, and won, a bet that his company could build the battery within "100 days from contract signature or it is free." The giant battery officially switched on in early December.

No matter the time of year, there's always a point in each season when my skin decides to cause me issues. While these skin issues can vary, I find the most common issues to be dryness, acne and redness.

Now, correspondence obtained by the LA Times revealed just how deeply involved industry lobbyists and a controversial, industry-funded toxicologist were in drafting the federal agency's proposal to scrap its current, protective approach to regulating toxin exposure.
February 22 is the birthday of conservationist and beloved TV personality "Crocodile Hunter" Steve Irwin, who would have been 57 years old today.
Irwin's life was tragically cut short when the barb from a stingray went through his chest while he was filming in 2006, but his legacy of loving and protecting wildlife lives on, most recently in a Google Doodle today honoring his birthday.

That video showed the extrusion of a bubblegum-pink substance oozing into a coiled pile, something between Play-Doh, sausage and soft-serve strawberry ice cream. Branded "pink slime"—the name came from an email sent by a USDA microbiologist in 2002—this stuff was actually beef, destined for supermarkets and fast-food burgers.
'Kicking Ass for Her Generation': Applause for 16-Year-Old Greta Thunberg as EU Chief Pledges Billions to Curb Climate Threat

Sixteen-year-old climate action leader Greta Thunberg stood alongside European Commission President Jean-Claude Juncker Thursday in Brussels as he indicated—after weeks of climate strikes around the world inspired by the Swedish teenager—that the European Union has heard the demands of young people and pledged a quarter of $1 trillion budget over the next seven years to address the crisis of a rapidly heating planet.
In the financial period beginning in 2021, Juncker said, the EU will devote a quarter of its budget to solving the crisis.
