Uganda: Filters turn dirty lake water into drinking water | Global Ideas
Innovation in Uganda.
Access to clean water may be a right, but it’s often hard to come by. Contaminated water kills. Henry Othieno and Saudah Birungi have developed eco-friendly filters for use in schools and homes. They turn dirty lake water into drinking water.

Meet Manta, a sea-cleaning sailboat that feeds on plastic waste
Excellent! Technology is available to make real change. Support efforts to clean the seas and use renewable energy sources.
Tired of hitting these floating objects during his races and seeing heavenly places turn into landfills, a French ocean adventurer Yvan Bourgnon decided to fight against this global scourge. He and his team have designed Manta, a giant, plastic-eating catamaran powered by renewable energy. The sea vessel literally scoops up plastic garbage and converts it into fuel to help power the boat.
Yvan Bourgnon – who has years of experience career racing sailing boats around the world’s oceans – is the mastermind behind the venture. A steady increase in encounters with floating fields of garbage in the ocean inspired him to start the SeaCleaners project and build Manta, a 56-meter (184 foot) catamaran powered by a combination of advanced sail technology and electric motors.
The giant sailing boat will be the first of its kind capable of collecting, processing, and recovering large quantities of marine plastic waste. Built from low-carbon steel, the Manta features a custom electric hybrid propulsion system that allows maneuvering at low speed for sensitive operations (such as the entry to and exit from ports), as well as waste collections, which are carried out at 2 or 3 knots. Agile and energy-efficient, the Manta can reach a top speed of over 12 knots.
Professor Dr. Mark Tester — Center for Desert Agriculture — KAUST — Red Sea Farms — Saudi Arabia
Unlocking The Potential Of Salt and Drought Tolerant Crops And Seawater Agriculture — Professor Dr. Mark Tester — Center for Desert Agriculture, King Abdullah University of Science and Technology; Co-founder & CSO, Red Sea Farms.
Professor Dr. Mark Tester is Professor, Plant Science, and Associate Director, Center for Desert Agriculture, Biological and Environmental Science and Engineering Division, of King Abdullah University of Science and Technology (KAUST) in Saudi Arabia.
Prior to joining King Abdullah University of Science and Technology in February 2013, Professor Tester was a professor of plant physiology at the University of Adelaide and the Australian Centre for Plant Functional Genomics from 2009 to 2013. He has a PhD from the University of Cambridge in plant sciences.
The aim of Professor Tester’s research program is to elucidate the molecular genetic mechanisms that enable certain plants to thrive in sub-optimal conditions, such as those of high salinity or high temperature, and then deliver the outputs in economically viable systems, such as barley, rice, tomatoes and quinoa.
An immediate applied aim of the program is to modify crop plants in order to increase productivity in conditions of challenging abiotic stress, with consequent improvement of yield in Saudi Arabia, the region and globally.
U.S. approves massive solar project in California desert
The Biden administration on Monday said it has approved a major solar energy project in the California desert that will be capable of powering nearly 90000 homes.
The $550 million Crimson Solar Project will be sited on 2000 acres of federal land west of Blythe, California, the Interior Department said in a statement. It is being developed by Canadian Solar (CSIQ.O) unit Recurrent Energy and will deliver power to California utility Southern California Edison.
The announcement comes as President Joe Biden has vowed to expand development of renewable energy projects on public lands as part of a broader agenda to fight climate change, create jobs and reverse former President Donald Trump’s emphasis on maximizing fossil fuel extraction.
New Metal-Air Battery Design Offers a Potential Boost to Electric Vehicles
Billy Hurley, Digital Editorial Manager.
Metal-air batteries are light, compact power sources with a high energy density, but they have had a major limitation: They corrode.
A new design from the Massachusetts Institute of Technology uses oil to reduce the corrosion and extend the shelf life of single-use metal-air batteries.
Researchers Identify the Defect That Limits Solar-Cell Performance: Hydrogen in Hybrid Perovskites
Researchers in the materials department in UC Santa Barbara’s College of Engineering have uncovered a major cause of limitations to efficiency in a new generation of solar cells.
Various possible defects in the lattice of what are known as hybrid perovskites had previously been considered as the potential cause of such limitations, but it was assumed that the organic molecules (the components responsible for the “hybrid” moniker) would remain intact. Cutting-edge computations have now revealed that missing hydrogen atoms in these molecules can cause massive efficiency losses. The findings are published in a paper titled “Minimizing hydrogen vacancies to enable highly efficient hybrid perovskites,” in the April 29 issue of the journal Nature Materials.
The remarkable photovoltaic performance of hybrid perovskites has created a great deal of excitement, given their potential to advance solar-cell technology. “Hybrid” refers to the embedding of organic molecules in an inorganic perovskite lattice, which has a crystal structure similar to that of the perovskite mineral (calcium titanium oxide). The materials exhibit power-conversion efficiencies rivaling that of silicon, but are much cheaper to produce. Defects in the perovskite crystalline lattice, however, are known to create unwanted energy dissipation in the form of heat, which limits efficiency.
Toyota built an internal combustion engine that sips hydrogen, and it sounds awesome
Japanese auto giant Toyota is working on a new-age hydrogen vehicle. When the words Toyota and Hydrogen are in the same sentence, the hydrogen-powered Toyota Mirai comes to mind. Still, the Mirai is a hydrogen-electric car or FCEV (fuel-cell electric vehicle). It uses hydrogen fuel to convert electricity and power an onboard electric motor. This time, Toyota came up with something different.
“At the end of last year, we built a prototype that provided that ‘car feeling’ that car lovers love, such as through sound and vibration, even though we were dealing with environmental technology, said Koji Sato, Chief Branding Officer, and Gazoo Racing Company President. ” It was only recently that I realized, as one thing led to another, that we could use technologies that we had on hand.”
Surely We Can Do Better Than Elon Musk

Scientists Finally Uncovered a Major Efficiency Flaw Holding Back Solar Cells
Perovskite has a lot going for it in our search for a cheap, efficient way to harvest solar energy. With a dusting of organic molecules, these crystalline structures have been able to convert more than a quarter of the light falling onto them into electricity.
Theoretically, perovskite crystals made with the right mix of materials could push this limit beyond 30 percent, outperforming silicon-based solar cells (which is currently the most abundant solar panel technology), and at a much lower cost. It’s all good on paper, but in reality, something has been holding the technology back.
Combine calcium, titanium, and oxygen under the right conditions and you’ll form repeating cages of molecules that look like a bunch of boxes joined at their corners.
