Could a Real-life Stillsuit Keep Us Alive on a Desert World?

Posted by in categories: space, sustainability

Could water-recycling suits help future astronauts survive on Mars?

It’s one of the most well-known pieces of speculative technology in science fiction: the Stillsuit.

As an essential feature of Frank Herbert’s Dune, the Stillsuit is the body-fluid recycling full-body suit worn by the Fremen of Arrakis, a technological adaptation to a desert world with almost no water but home to an extremely valuable resource that leads to human colonization of the barren planet.

Look at how much the planet has changed in four decades with Google Earth Timelapse

Posted by in categories: climatology, sustainability

What if we could go back in time to four decades ago, when we first heard the term “climate change,” and take a good look at planet Earth?

The new Google Earth Timelapse feature lets us do that. We can scan the globe and look back from the present day to 1984. The feature gives us a unique opportunity to see how human action and natural forces have changed the planet since the 1980s.

Bangkok’s noisy scooter-filled streets may quiet down with new electric motorcycle trial

Posted by in categories: government, sustainability, transportation

The Thai government is starting a new trial in Bangkok that will see electric scooters replace their gas counterparts for motorcycle taxis in the city.

The trial run could have big implications not just for Bangkok, but for scooter and motorcycle-laden cities across much of Asia.

If you’ve ever visited Thailand, you’ll surely have seen two of their most popular forms of public transportation that we don’t offer here in the West: rickshaws (tuk-tuks) and motorcycle taxis.

Posted by in categories: computing, sustainability, transportation

Tesla has introduced the new AMD Ryzen chip and 12v Li-ion battery in 2022 Model 3 Model Y vehicles.

Earlier this month, we reported on a bunch of new features and changes coming to the Tesla Model 3 and Model Y that leaked through a test program in Europe.

Amongst many things, the leak revealed that new Model 3 and Model Y vehicles coming to Europe, which are made in China, would come with the new AMD Ryzen chip that is powering the media computer in the new Model S and Model X and the Model Y Performance made in China. Also, the lead-acid 12v battery will change to a Li-ion battery system.

Introducing the light-operated hard drives of tomorrow

Posted by in categories: computing, solar power, sustainability

Circa 2020


What do you get when you place a thin film of perovskite material used in solar cells on top of a magnetic substrate? More efficient hard drive technology. EPFL physicist László Forró and his team pave the way for the future of data storage.

“The key was to get the technology to work at room temperature,” explains László Forró, EPFL physicist. “We had already known that it was possible to rewrite magnetic spin using light, but you’d have to cool the apparatus to—180 degrees Kelvin.”

South Korean 20-Mile Solar ‘Bike Highway’ Generates Electricity

Posted by in categories: solar power, sustainability, transportation

Sunny way.


A ‘bike highway’ running between Daejon and Sejong in South Korea is a sight —or rather, a concept —, you surely haven’t thought of before: It stretches for 20 miles (32 km), and it not only shields cyclists from the sun but also generates power at the same time.

A Vertical Farm Company Aims to Reduce Food Waste With Local Produce

Posted by in categories: energy, food, space, sustainability

With hundreds of times more food per acre than regular farms.

Vertical farming is a revolutionary form of agriculture. As its name suggests, it’s a form of agriculture that is specifically designed to facilitate agricultural production inside vertical structures. These farms can be created inside old warehouses, used shipping containers, greenhouses, or other buildings, saving space and energy.

As a more sustainable method of farming, vertical farming tends to require much less energy than regular farming which is estimated to be 95% less water since the used water in farming can be recycled and reused.
