What If We Pave Plastic Trash Into New Roads? | World Wide Waste

Turning plastic waste into roads.

Presented by BASF

A company in Nairobi wants to install bricks made from plastic trash across Kenya’s capital. Could they become a solution for a country where 90% of roads have never been paved? And are roads made from plastic really a good idea?

Hydrogel Tablet Can Purify a Liter of River Water in an Hour

AUSTIN, Texas — As much as a third of the world’s population does not have access to clean drinking water, according to some estimates, and half of the population could live in water-stressed areas by 2025. Finding a solution to this problem could save and improve lives for millions of people, and it is a high priority among scientists and engineers around the globe.

Scientists and engineers at The University of Texas at Austin have created a hydrogel tablet that can rapidly purify contaminated water. One tablet can disinfect a liter of river water and make it suitable for drinking in an hour or less.

“Our multifunctional hydrogel can make a big difference in mitigating global water scarcity because it is easy to use, highly efficient and potentially scalable up to mass production,” said Guihua Yu, an associate professor in the Cockrell School of Engineering’s Walker Department of Mechanical Engineering and Texas Materials Institute.

Elon Musk confirms that Tesla Giga Shanghai now exceeds the Fremont Factory

Tesla Giga Shanghai has officially exceeded the Fremont Factory’s output, according to Elon Musk’s calculations. As Tesla’s main export hub, Giga Shanghai’s output will play a significant role in the company’s global growth.

“We have three new factories. Giga Shanghai has done an incredible job. And Giga Shanghai now exceeds Fremont in production,” Musk announced at the 2021 Annual Shareholders Meeting.

Musk pointed out that Tesla Giga Shanghai took roughly 11 months to build and reached full volume production a year later. Since Giga Shanghai started operations, Tesla’s production and delivery numbers have noticeably increased.

Electric Aircraft Has Unlimited Range… With A Fleet Of Recharging Planes

Circa 2012

It’s okay, you’ve not clicked on “Green Plane Reports”, but every so often something from beyond the world of cars catches our attention.

This time, it’s electric flight. The concept is nothing new, and it’s even been alluded to by people like Elon Musk of Tesla, but for the time being it remains a true flight of fancy, rather than a working concept for passenger transportation.

The video above suggests one such way of making the concept workable. We’ll leave you to form your own thoughts, but we can forsee a few disadvantages.

In dry California, some buy units that make water from air

In drought-parched California, some residents are turning to pricey machines that developers say can produce hundreds of gallons of water a day, literally out of thin air.

BENICIA, Calif. (AP) — The machine Ted Bowman helped design can make water out of the air, and in parched California, some homeowners are already buying the pricey devices.

The air-to-water systems work like air conditioners by using coils to chill air, then collect water drops in a basin.

“Our motto is, water from air isn’t magic, it’s science, and that’s really what we’re doing with these machines,” said Ted Bowman, design engineer at Washington state-based Tsunami Products.

Elon Musk’s airport-to-downtown S.A. tunnel transit plan takes a step forward; transportation agency seeks proposals

When it surfaced two months ago, the notion of Teslas whizzing through underground tunnels between San Antonio International Airport and downtown seemed fanciful.

Now, there’s a sign the idea may have gained some traction.

The Boring Co., a tunneling firm backed by billionaire Elon Musk, has been talking to local leaders about building an underground transportation loop in San Antonio. Musk is the CEO of electric-vehicle maker Tesla, as well as the founder and CEO of SpaceX.

Catalysts found to convert carbon dioxide to fuel

The goal of tackling global warming by turning carbon dioxide into fuel could be one step closer with researchers using a supercomputer to identify a group of “single-atom” catalysts that could play a key role.

Researchers from QUT’s Centre for Materials Science, led by Associate Professor Liangzhi Kou, were part of an international study that used theoretical modelling to identify six metals (nickel, niobium, palladium, rhenium, rhodium, zirconium) that were found to be effective in a reaction that can convert into sustainable and clean energy sources.

The study published in Nature Communications involved QUT researchers Professor Aijun Du, Professor Yuantong Gu and Dr. Lin Ju.

A UK Company Revealed a New Electric Hybrid Car. But It’s Also a Bike?

Get ready for the future of mobility.

The world is moving to electric vehicles (EVs), but we are still rolling on vehicle concepts meant for heavy internal combustion engines. Challenging the very concept of what a mobility solution should look like is the Ryzr, from new players in the EV market, R.

As the pandemic pushed people to opt for more independent mobility solutions, bicycle sales rocketed in many parts of the world, the BBC reported last year. With its open concept, R’s Ryzr is designed to offer the same thrill as cycling does on open streets but with a more relaxed car-like seating comfort.
