Scientists Are Recycling Wastewater to Reclaim Valuable Phosphorous to Put Back in Soil
Scientists have taken pollutant phosphorus from wastewater and infused it into a soil superfood called biochar to really “close the loop” on several widespread agricultural practices.
The biochar itself is made from incinerated organic material inside an oxygen-deprived environment, turning it into charcoal that acts like an underground rainwater sponge that also delivers the necessary phosphorus and other nutrients for plant growth.
Animal life needs energy in the form of the four macronutrients: carbohydrates, fatty acids, amino acids, and ketone bodies.
Plant life operates a bit differently. One of the green kingdom’s macronutrients is phosphorus, and its presence in the soil greatly contributes to healthy crops. Phosphorus runoff into streams is a major problem for sea life because once this basic element reaches the ocean, it causes giant blooms of algae that block light from reaching the seabed.
On its way there, this same problem can occur with riverine plants, and so is also considered pollution in fresh water.

NASA Unveils an X-Plane They Hope Will Save Earth
They believe that with new designs, tech, and materials, this experiment could lead to a 30% reduction in fuel usage in aviation. That in itself would be a win. Making planes quieter would also be a win for those in flight paths near airports, and wouldn't suck in general for everyone else.

Here's another that I believe has been shared before, or at least a similar(ish) process.
Clean Fuel Made by Pulling CO2 From Air and Plastic Waste - Powered Only by the Sun and Photosynthesis
Cambridge University researchers have demonstrated how carbon dioxide can be captured from industrial processes – or even directly from the air – and transformed into clean, sustainable fuels using just the energy from the sun.
They developed a solar-powered reactor that uses captured CO2 and plastic waste (which acts as a catalyst) and converts it into sustainable fuels and other valuable chemical products.
Over several years of testing, CO2 was converted into syngas, a key building block for sustainable liquid fuels, and plastic bottles were converted into glycolic acid, which is widely used in the cosmetics industry.
Unlike earlier tests of their solar fuels technology, however, the team took CO2 from real-world sources—such as industrial exhaust or the air itself. They were able to capture and concentrate the CO2 and convert it into sustainable fuel.
The researchers appreciate the advances in carbon capture and storage, where CO2 is captured and then pumped and stored underground. But instead, they believe the smart move is ‘carbon capture and utilization’—making something useful from CO2 instead of burying it underground.
Something like photosynthesis—the inspiration behind the work done by Professor Erwin Reisner and his team in the Department of Chemistry and at the Cambridge Circular Plastics Centre where they develop net-zero carbon fuels.
To date, their solar-driven experiments used pure, concentrated CO2 in cylinders, but for the technology to be of practical use, it needs to actively capture CO2 from the air, which is a huge technical challenge because the air contains many types of molecules besides CO2. That’s where the plastic came in handy.

It will be interesting to see where these ideas end up down the road.
NASA Unveils an X-Plane They Hope Will Save Earth
NASA and Boeing have unveiled the plane they hope will save the Earth.
The aim is for the experimental aircraft to help reach a net zero aviation emissions goal by 2050 in the U.S.
Working with NASA as part of a $725 million agreement, Boeing will build, test, and fly a full-scale demonstrator aircraft with extra-long, thin wings stabilized by diagonal struts, known as a Transonic Truss-Braced Wing concept.
It is hoped the new X-plane will inform a potential new generation of more sustainable single-aisle aircraft, which is the workhorse of passenger airlines around the world.
The space agency and Boeing said the aircraft produced through the agency’s Sustainable Flight Demonstrator project has been designated by the U.S. Air Force as the X-66A.
“At NASA, our eyes are not just focused on stars,” said NASA Administrator Bill Nelson. “The Sustainable Flight Demonstrator will help shape the future of aviation, a new era where aircraft are greener, cleaner, and quieter, and create new possibilities for the flying public and American industry alike.”
The X-66A is the first plane specifically focused on helping the U.S. achieve the goal of net-zero aviation greenhouse gas emissions.

If you were to take this absurd prediction seriously, that would mean we all have only ten days left.
Not a political statement, but bears a striking resemblance in some pics to Veruca Salt from Willie Wonka

There's a bunch of electric cars utilizing solar panels now. Some can charge as much as 20 miles of range a day sitting in the parking lot. The average commute to and from work is 41 miles. We are getting closer... to freedom.

Closer to home. Does anybody really believe that this will happen?
https://news.yahoo.com/bidens-oil-co...ffKDO33QFe82ox
President Joe Biden sparked a firestorm in energy circles when he said in Tuesday's State of the Union address that the United States will need oil “for at least another decade.″
The Biden administration plans to eliminate fossil fuels as a form of energy generation in the U.S. by 2035. The White House set out a target of 80% renewable energy generation by 2030 and 100% carbon-free electricity five years later.
