You’ve Heard of Vantablack. Scientists Just Created ‘Super White’, And It’s Very Cool

Posted by in categories: energy, materials

Scientists have created a super white paint that is the yin to Vantablack’s yang.

While ultra black materials can today absorb more than 99.96 percent of sunlight, this new super white coat can reflect 95.5 percent of all the photons that hit it.

Instead of warming up under direct light, objects painted with this new acrylic material can remain cooler than their surrounding temperature even under the Sun, which could allow for a new energy-efficient way to control temperature inside buildings.

It’s Official: Solar Is the Cheapest Electricity in History

Posted by in categories: energy, finance, sustainability

Just a matter of time.


In a new report, the International Energy Agency (IEA) says solar is now the cheapest form of electricity for utility companies to build. That’s thanks to risk-reducing financial policies around the world, the agency says, and it applies to locations with both the most favorable policies and the easiest access to financing. The report underlines how important these policies are to encouraging development of renewables and other environmentally forward technologies.

☀️ You love renewable energy. So do we. Let’s nerd out over it together.

Spinach Gives Fuel Cells a Power Up

Posted by in categories: energy, food

Didn’t Popeye always say to eat your spinach?

You may want to add it to your fuel cells too!


Spinach-based catalysts could power fuel cells more efficiently than traditional platinum ones.

Solar and Covid lead change as grid demand, prices and emissions tumble to record lows

Posted by in categories: biotech/medical, energy

Rooftop solar, Covid and more large scale renewables push Australia’s main grid to record low levels of demand and emissions intensity, and the lowest prices in years.


The combined impact of growing rooftop solar and the Covid-19 pandemic – along with the continued influx of large scale wind and solar – has create a suite of new records in Australia’s electricity grids in the September quarter, sending demand, emissions and prices to new lows.

The latest Quarterly Energy Dynamics for the September quarter, compiled by the Australian Energy Market Operator, also noted record highs for wind and solar output, which along with falling gas prices and cut-price bidding by coal generators trying to stay competitive led to the lowest wholesale prices in more than five years, and in some cases, record low prices.

Twin peaks: South Australia reaches 100 pct solar, and then 100 pct wind power in same week

Posted by in categories: energy, government, sustainability

Australia seems to be leading the way in terms of wind power as well. 😃


It was a big week for South Australia last week. First, as we wrote at the time, the state reached 100 per cent solar power (of state demand) for the first time on Sunday, October 11.

Then, just a few days later, the state reached 100 per cent wind power (of state demand), on Thursday, October 15.

Perfect Energy Efficiency: Quantum Engines With Entanglement as Fuel?

Posted by in categories: energy, quantum physics, transportation

University of Rochester researcher receives $1 million grant to study quantum thermodynamics.

It’s still more science fiction than science fact, but perfect energy efficiency may be one step closer due to new research at the University of Rochester.

Metallic Hydrogen

Posted by in categories: energy, futurism

The third-order term Fpot(ρ)[ρq] Fpot(ρ)[ρq] above corresponds to the third-order energy in the structural expansion for electron systems. This energy plays an important role in the structural stability of metallic hydrogen 16 (Z= 1). This is because the kernel (10) has a strong wave-vector dependence, which cannot properly be treated in the square-gradient type theory. This brings a special stability of the structure in which as many equilateral triangles with q=3kF appear in the reciprocal lattice. It requires an anisotropic structure or a periodic modulation of the lattice for an atomic phase of hydrogen. Another possibility is to form a crystal with two ions in a unit cell (molecular phase). In any case, the atomic phase of bcc structure would not be realized just under the melting line as log as the third order term in Fcq] does not suppress the effect. We shall investigate this problem numerically in the near future.
