>When natural disasters strike, one of the first crucial resources that can get disrupted is electricity. Startup Sesame Solar thinks it's found a solution to providing power for emergency crews and displaced residents with its mobile Nanogrids.

>At first glance, a Nanogrid may look like a food truck. It's designed to be hauled the same way you'd transport a moving trailer. But once deployed, the solar panels that line the Nanogrid are revealed. The panels charge the onboard batteries, and the company says a single Nanogrid can produce anywhere from 3 to 20 kilowatts. That's enough to power four to six houses.

> Lauren Flanagan, Sesame's co-founder and CEO, calls the Nanogrid the world's first 100% renewably powered mobile system. "You don't need fossil fuel. You don't need diesel or natural gas. Just water and sunshine," she said. Watch the video above to learn more about how the Nanogrids work.

>In addition to solar power, the Nanogrids are equipped with a hydrogen fuel cell that turns water into hydrogen. The hydrogen can be stored in tanks and used to charge the batteries when they dip below 35%. Nanogrids also have an onboard water filtration system that can provide up to 500 liters of potable water per day, and a 5G mesh network so people displaced in a disaster can get online.

>this is an indication that Fossil Fuels are not a good investment for the future and banks and businesses are beginning to see that

So your telling me the "go woke go broke" crowd is wrong again? Aren't these the same individuals that keep crowing 'Let the free market decide!" While demanding subsidies for corn?

>Literally no one in any large western economy is "working to expand oil and gas extraction."

The State of Wyoming has entered the chat.

Wyoming Wants to Ban Electric Vehicles by 2035 Six Republican legislators introduced a bill to phase out EV sales in the next 12 years.

Wyoming stands up for coal with threat to sue states that refuse to buy it. Republican governor says measure sends message that Wyoming is ‘prepared to bring litigation to protect her interests’.

Oh right you said large economy. Wyoming ranks 50th in GDP and is Republican shithole State welfare Queen that takes more from the Union than it contribute. Uh, carry on then.

>WATER IS URBAN planners’ nemesis. Because the built environment is so impervious to liquid, thanks to all that asphalt, concrete, and brick, water accumulates instead of seeping into the ground. That’s how you get the extreme flooding that has plagued California for weeks, so far killing 19 people and causing perhaps $30 billion in damages.

>Traditionally, engineers have treated stormwater as a nuisance, building out complex infrastructure like drains and canals to funnel the deluge to rivers or oceans before it has a chance to puddle. But in California and elsewhere, climate change is forcing a shift in that strategy. As the world warms, more water evaporates from land into the atmosphere, which itself can hold more water as it gets hotter. Storms in the Golden State will come less frequently, yet dump more water faster when they arrive. Stormwater drainage systems just can’t get the water away fast enough.

>To prepare for this soggy future, engineers are turning to another plan for flood control, forcing water to seep underground into natural aquifers. Such a plan will simultaneously mitigate flooding and help the American West store more water despite a climate gone haywire. “We need to think a little bit more creatively about: How do we most effectively utilize basically these huge underground sponges that we can use to supply potable water?” says Katherine Kao Cushing, who studies sustainable water management at San José State University.

>To hydrate its people and agriculture, California is stepping up water conservation efforts, like getting more low-flow toilets into homes and paying people to rip out their lawns, which are terrible for all kinds of reasons beyond their thirstiness. It’s recycling wastewater from homes and businesses into ultra-pure water you can actually drink. But most of all, it’s trying to hold onto its sporadic rainwater, instead of draining it away, building out infrastructure to create “sponge cities.” These are popping up all over the world; the concept has been widely deployed in China, and city planners in places like Berlin in Germany and Auckland in New Zealand are using it to come to grips with heavier rainfall.

>In California, Los Angeles is leading the way. The Los Angeles Department of Water and Power has invested $130 million in stormwater capture projects, like the Tujunga Spreading Grounds shown above—150 acres of dirt basins that average 20 feet deep. Stormwater is pumped into these bowls and seeps underground for later extraction; the agency expects it to provide enough water for 64,000 households a year.

>In their experiment, they compared how a muscle and a traditional direct-current (DC) motor would lift a weight up from the ground. The DC motor will yank the object with the maximum amount of force it can apply at that moment and will continue doing so as it lifts the weight.

>"The construction of muscle, however, allows for a more fluid, continuous and gradual movement," McGrath said. "Muscle can smoothly lift the object that does not require it to continuously yank on the weight as with all of its power."

>To have their motor behave like the fluid, energy-efficient muscle, the researchers used a device called a proportional-integral-derivative controller (PID), which works like cruise control in a car. The PID can recognize an error between the current speed and the set speed of cruise control and corrects by increasing or decreasing the force.

>Muscles have been shown to provide performance advantages useful for robotic systems, such as energy efficiency, stability, or increased range in motion. How muscles create these performance advantages, however, still remains largely unknown.

>As demand for electric vehicles soars, scientists are searching for materials to make sustainable batteries. Lignin, the stuff that makes trees woody, is shaping up to be a strong contender.

>"Lignin is the glue in the trees that kind of glues the cellulose fibres together and also makes the trees very stiff," explains Lauri Lehtonen, head of Stora Enso's lignin-based battery solution, Lignode.

>Lignin, a polymer, contains carbon. And carbon makes a great material for a vital component in batteries called the anode. The lithium ion battery in your phone almost certainly has a graphite anode – graphite is a form of carbon with a layered structure.

>Stora Enso's engineers decided that they could extract lignin from the waste pulp already being produced at some of their facilities and process that lignin to make a carbon material for battery anodes. The firm is partnering with Swedish company Northvolt and plans to manufacture batteries as early as 2025.

Around three billion litres of water are lost through leaks across hundreds of thousands of miles of water pipe in England and Wales daily, says water industry economic regulator Ofwat.

Engineers have now developed miniature robots to patrol the pipe network, check for faults and prevent leaks.

They say maintaining the network will be "impossible" without robotics.

Water industry body Water UK told BBC News that companies were already "investing billions" in leakage.

>Researchers hope a "world first" algorithm that predicts serious brain bleeds before they happen could save lives across Australia.

>Royal Perth Hospital head of data science, Shiv Meka, said more than 40,000 hours of patient data had been collected from 200 patients from Royal Perth Hospital, Alfred Hospital, and Royal Melbourne Hospital to develop the algorithm.

>After working on 20 different data models, Mr Meka and his team created one that could predict if a brain bleed was imminent — giving medical staff up to 20 minutes before the bleed to intervene.
