Italy’s Government Collapses, Turning Chaos Into Crisis

A power play by the popular interior minister, Matteo Salvini, imploded the coalition. But for now, the election he wants remains just out of reach.

Nuclear Pumped Lasers and the Strategic Defense Initiative

Posted by in categories: energy, military

Circa 2018

In 1963, L. Herwig proposed the nuclear pumped laser, based on the idea that the ions produced from nuclear reactions can be used as a driver for the laser medium. Since high power and high efficiency lasers with short wavelengths require high pumping power densities, nuclear pumping is an extremely appealing method. Nuclear pumped lasers could therefore direct significant amounts of energy emitted in a nuclear explosion into a very narrowly collimated beam. This beam would not only be able to destroy or damage targets from very long ranges, but also preclude subsequent use due to its own self-damaging mechanism to the initial weapon. [1] This system would ultimately constitute “a ‘third generation’ of nuclear weapons, the first two generations being the atomic (fission) and the hydrogen (fusion) bombs,” according to Edward Teller, also known as “the father of the hydrogen bomb”. [2] In this sense, it would be able to target energy toward specific targets instead of spreading energy into all directions.

World’s Largest Offshore Wind Farm Will Power 4.5 Million Homes

Posted by in categories: energy, sustainability

But a new figure blows all of these out of the water. Last week, British renewable energy developer SSE announced construction of Dogger Bank Wind Farm off the eastern coast of England in the North Sea.

With a capacity of 3.6 gigawatts (GW), Dogger Bank will be three times bigger than the world’s biggest existing wind farm, the nearby 1.2 GW Hornsea One.

Located near a seaside town called Ulrome, which is 195 miles north of London, Dogger Bank will have three separate sites—Creyke Beck A, Creyke Beck B, and Teesside A—each with a 1.2 GW capacity, and construction is slated to take two years.

ESA opens plant that turns moondust into oxygen

Posted by in categories: energy, space

If humans are going to have a long-term presence on the Moon, they’re going to need breathable air and rocket fuel — and the ESA might just have a way to create both using the Moon itself. The agency is running a prototype plant that converts moondust (currently simulated, of course) into oxygen that could be used for air and fuel. The technique unlocks the high amounts of oxygen in regolith using molten salt electrolysis that superheats the dust and migrates the oxygen along the salt until it’s collected at an anode. The basic process has already been used for metal and alloy production, but the ESA tweaked it to ensure oxygen was available to measure.

Radeon RX 5600 XT with new vBIOS boost shows impressive new benchmark scores

Posted by in category: energy

Then, we learned that AMD pushed out a new vBIOS to its AIB partners as a response to Nvidia’s price cuts on the RTX 2060 in what’s been a back and forth volley between the two companies at the $300 price point.

The new vBIOS ratchets up the TBP (Typical Board Power) to 160W, a 10W increase from the original 150W TBP. This in turn affords AMD’s board partners a higher margin for core and memory clocks. Which brings us to Sapphire, one of AMD’s premiere AIB partners.

As we previously reported, Sapphire’s RX 5600 XT Pulse is now boasting increased base and boost clocks of 1,615 MHz and 1,750 MHz, up from the previous 1,560 MHz and 1,620 MHz. The memory clock is now running at 14Gpbs effective, as opposed to 12Gpbs.

Student debt is over $1.6 trillion and hardly anyone is paying down their loans

Posted by in categories: education, energy

Since the explosion of student debt following the Great Recession, annual repayment rates, or the amount of existing balances lowered, have been just 3%, Moody’s said. Just 51% of borrowers who took out loans from 2010-12 have made any progress at all in paying down their debt.

“While in the past, higher enrollment and rising tuition were the main drivers of growing student loan balances, more recently, slow repayments have become the primary driver,” Jody Shenn, senior analyst at Moody’s, and others said in the report. “Over the next few years, the combination of slow repayments and elevated, if no longer growing, levels of new borrowing will likely fuel further increases in outstanding debt.”

There are multiple reasons why the debt levels are not going down.

NASA Wants to Grow a Moon Base Out of Mushrooms

Posted by in categories: energy, habitats, space

Fungus Among Us

The idea is to ship dormant fungus to a Moon base and, once it arrives, give it water and the right conditions to trigger growth, according to a NASA press release. That would also require a supply of photosynthetic bacteria to provide the fungus with nutrients. Once the fungus grows into the shape of a structure, it would be heat-treated, effectively killing it and turning it into a compact brick.

Conspiracists say lasers used to start bushfires to make way for a new train network

Posted by in categories: energy, transportation

Thousands of Australians appear to believe lasers and exploding smart meters are being used to start our bushfires to make way for a new train network.

A Storyful investigation with news.com.au has found the conspiracy theory has spread far and wide on social media — with “directed-energy weapons” (DEWs) posts being shared tens of thousands of times in the past few weeks.

Those who believe the theory say the bushfires in this unprecedented season are being started using weapons which harness the focused power of technology such as lasers or microwaves.
