>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?

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.
