This Satellite Could Be Beaming Solar Power Down from Space

Posted by in categories: solar power, space, sustainability

In the third century BCE, King Hiero II of Syracuse asked Archimedes to devise a number of death traps to thwart Roman invaders. Among the many designs the great inventor drew up was a solar death ray. The basic idea was to build an array of mirrors that could reflect rays of light into a central blast, causing Roman ships to burst into flame. It’s unlikely the weapon ever made it past the blueprint stage, but it became an incredibly influential model nonetheless. Archimedes was perhaps the first solar power convert, searching for a way to take advantage of the inconceivable amount of energy our friendly neighborhood star barfs up every second.

The only thing that would make Archimedes’ solar death ray more fascinating is if it was technically feasible, socially benevolent, and in space. That’s where John Mankins comes in. A NASA veteran, aerospace entrepreneur, and space-based solar power (SBSP) expert, Mankins designed the world’s first practical orbital solar plant. It’s called the Solar Power Satellite via Arbitrarily Large PHased Array, or SPS-ALPHA for short. If all goes to plan, it could be launched as early as 2025, which is sooner than it sounds when it comes to space-based solar power timelines.

Scientists have been aware of the edge the “space-down” approach holds over terrestrial panels for decades. An orbiting plant would be unaffected by weather, atmospheric filtering of light, and the sun’s inconvenient habit of setting every evening. SBSP also has the potential to dramatically increase the availability of renewable energy.

Elon Musk Says Tesla Vehicles Will Drive Themselves in Two Years

Posted by in categories: Elon Musk, robotics/AI, space travel, sustainability, transportation

Musk opens up about autonomous vehicles, self-driving car rules, and the competition.

In Elon Musk’s world, “easy” is used to describe problems many might consider impossible—or at least very difficult to solve. Producing a fully autonomous vehicle that can operate in any condition and on any road, for example, is easy-ish. And Tesla Motors TSLA 0.91%, the all-electric automaker that Musk heads, is two years away from achieving it.

“I think we have all the pieces, and it’s just about refining those pieces, putting them in place, and making sure they work across a huge number of environments—and then we’re done,” Musk told Fortune with assuredness during his commute to SpaceX headquarters in Hawthorne, Calif., where he is also CEO. “It’s a much easier problem than people think it is. But it’s not like George Hotz, a one-guy-and-three-months problem. You know, it’s more like, thousands of people for two years.”

Why Algae Could Be the Greatest—and Trickiest—Fuel Source of All

Posted by in categories: climatology, nuclear energy, sustainability

I recall when Venter made the first synthetic unique life form he said biofuels and algae that soaks up carbon dioxide would come out of it. Feels like it has been slow going but here is a why and why no item and please read the comments too as they are also informative.


From powering airplanes to replacing nuclear energy, algae has been touted as a green energy miracle. So if our waterways are already filled with the stuff, why isn’t it filling the world’s skies with biofueled planes? Algae is a tricky creature that presents a lot of challenges and misconceptions. Here’s why it’s difficult to harness—and why it could big a big payoff.

As we previously reported, algae is a fuel source that’s vastly more eco-friendly than oil, and will be crucial as we head into a future filled with climate change and depleting fossil fuels.

An organic mixed ion-electron conductor for power electronics

Posted by in categories: electronics, materials, sustainability

Researchers at Linköping University’s Laboratory of Organic Electronics, Sweden, have developed power paper — a new material with an outstanding ability to store energy. The material consists of nanocellulose and a conductive polymer. The results have been published in Advanced Science.

One sheet, 15 centimetres in diameter and a few tenths of a millimetre thick can store as much as 1 F, which is similar to the supercapacitors currently on the market. The material can be recharged hundreds of times and each charge only takes a few seconds.

It’s a dream product in a world where the increased use of renewable energy requires new methods for energy storage — from summer to winter, from a windy day to a calm one, from a sunny day to one with heavy cloud cover.

Google makes ‘largest purchase’ of renewable energy to power data centers: 842 MW across 3 countries

Posted by in categories: business, finance, sustainability

Google says it wants to power 100% of its operations from renewable energy.


Google has announced a slew of renewable energy projects, as it moves to meet its commitment to power 100 percent of its business from green energy sources.

In what it calls the “largest, and most diverse, purchase of renewable energy ever made by a non-utility company,” Google said it has added 842 megawatts (MW) of renewable energy to its data centers, which nearly doubles the amount of clean energy it has already bought. Most of the renewable energy has been purchased for locations in the U.S., but Google said it has added more than 150 megawatts from a solar plant in Chile and a wind farm in Sweden.

Coming to a monitor near you: a defect-free, molecule-thick film

Posted by in categories: computing, materials, nanotechnology, solar power, sustainability

An emerging class of atomically thin materials known as monolayer semiconductors has generated a great deal of buzz in the world of materials science. Monolayers hold promise in the development of transparent LED displays, ultra-high efficiency solar cells, photo detectors and nanoscale transistors. Their downside? The films are notoriously riddled with defects, killing their performance.

For Israeli firm, an answer to global warming blowing in the wind

Posted by in category: sustainability

For an Israeli start-up, one answer to global warming is blowing in the wind. The company called NewCO2Fuels, or NCF, has been developing its own version of a technology that allows heat-trapping carbon dioxide emissions to be captured and recycled back into useable fuel.

It sounds complicated—and it is—but the company’s founders say it holds real potential in the fight against .

Such capture technologies have gained increased attention as countries seek alternative methods of cutting back on , the main culprit in global warming.

US electrical grid can’t affordably store enough standby electricity to keep the system stable, says researcher

Posted by in categories: solar power, sustainability

A common criticism of a total transition to wind, water and solar power is that the US electrical grid can’t affordably store enough standby electricity to keep the system stable. Now a researcher proposes an underground solution to that problem.
