Scientists are trying to bottle solar energy and turn it into liquid fuel

Posted by in categories: solar power, sustainability

What if we could bottle solar energy so it could be used to power our homes and factories even when the sun doesn’t shine?

Scientists have spent decades looking for a way do just that, and now researchers in Sweden are reporting significant progress. They’ve developed a specialized fluid that absorbs a bit of sunlight’s energy, holds it for months or even years and then releases it when needed. If this so-called solar thermal fuel can be perfected, it might drive another nail in the coffin of fossil fuels — and help solve our global-warming crisis.

Unlike oil, coal and natural gas, solar thermal fuels are reusable and environmentally friendly. They release energy without spewing carbon dioxide and other greenhouse gases into the atmosphere.

The Wonders and Worries of ‘Extinct Animal’ Zoos

Posted by in categories: climatology, existential risks, sustainability

The future is both glorious and horrifying. As we continue to expand our technological footprint in the hopes of creating wonder, several issues remain fixed with a trajectory towards disaster. From climate change to the mass extinction of several animal species, there’s no doubt that we’re heading into ruin if we’re to keep this up.


As our technology continues to advance to the point of bringing the dead back to life, how will our own species react to a growing new population of animals that can die and live again?

Carp ‘annihilated’ as Iraq’s water pollution woes worsen

Posted by in categories: food, sustainability

HINDIYAH, Iraq (AP) — Iraqi officials and fishermen are at a loss to explain how hundreds of tons of carp have suddenly died in fish farms in the Euphrates River, fueling anxieties about soaring water pollution.

Local authorities used excavators to skim dead fish from the river surface near the town of Hindiyah, 80 kilometers (50 miles) south of Baghdad, where residents and local farmers have long complained about substandard water management.

The fish were being farmed in cages for sale in domestic markets, where grilled carp is considered a national dish, called masgouf.

Mining for Rocket Fuel on the Moon

Posted by in categories: solar power, space, sustainability

Over the past few months, I was part of a study funded by the United Launch Alliance and supported by a large group of technologists to determine if we can mine water on the Moon and turn it into rocket fuel, and to do it economically. The final report can be downloaded here.

Why Mine Water on the Moon?

The lunar water would be launched off the Moon and delivered to a “gas station” in Earth orbit. This propellant depot will use solar energy to turn the water into rocket fuel. Then, space tugs can refill their tanks so they can repeatedly boost spacecraft from Geosynchronous Transfer Orbit (GTO) (where the launch rocket throws them) into Geosynchronous Orbit (GEO) where they can begin operating.

SpaceX’s ‘Starman’ and Its Tesla Roadster Are Now Beyond Mars

Posted by in categories: space travel, sustainability

Starman has put a lot of miles on his Tesla Roadster in the last nine months.

The red electric car and its spacesuit-clad mannequin driver, which launched on the maiden mission of SpaceX’s huge Falcon Heavy rocket in February, have made it beyond the orbit of Mars, company representatives said Friday night (Nov. 2).

“Starman’s current location. Next stop, the restaurant at the end of the universe,” SpaceX posted on Twitter Friday, along with an orbit diagram. [Epic SpaceX Road Trip Photos: Starman Rides a Tesla Roadster in Space].

Starman and Tesla Roadster Have Shot Past Mars, SpaceX Says

Posted by in categories: Elon Musk, space travel, sustainability

SpaceX’s Starman and cherry red Tesla Roadster have traveled beyond Mars. SpaceX shared a diagram of the car once driven by the aerospace manufacturer’s CEO Elon Musk indicating it has now reached beyond the Red Planet.

Sharing Starman’s current position in a diagram to Twitter, SpaceX also tweeted a nod to Douglas Adams’ seminal work The Hitchhiker’s Guide to the Galaxy, which is beloved by Musk. (The Restaurant at the End of the Universe refers to the second book in the series.) The dash of the Roadster itself even has a nod to Hitchhiker’s Guide, as Space.com notes the words “Don’t Panic” on its control panel also appeared on a cover of the novel.

Another Tesla with Autopilot crashed into a stationary object—the driver is suing

Posted by in categories: robotics/AI, sustainability, transportation

To be fair to Tesla, this problem isn’t unique to the company. Most emergency braking systems on the market today won’t stop for stationary objects at freeway speeds. These systems are not sophisticated enough to distinguish a stationary object on the road from one that’s next to or above the road. So to make the problem easier to handle, the cars may just ignore stationary objects, assuming that the driver will steer around them.


Florida man says Tesla oversold Autopilot’s capabilities.
