They make their own and were indigenous to much of the west, even pretty far south and in numbers can change the environment by retaining water that normally runs off.
How Beavers Are Restoring Wetlands in North American Deserts!
616,111 views Sep 3, 2023
In the deserts of north America something incredible is happening, these arid lands are turning into lush green wetlands and its all because of a very secretive creature who only comes out at night
and the results are surprising everyone!
Determined, relentless and even stubborn are words commonly used to describe one natures hardest workers, they work tirelessly through the night, night after night, while most people are asleep...
I'm talking about beavers of course
and despite their controversial and complex relationship with man in the past, there are a growing number in the science world who are coming to the realization that beavers could actually be a friend and not foe, who can help us win the fight to save the environment.In this video we will show you how beavers have saved desert rivers over the course of 12 years, and the landscapes beavers create that can help to fight wildfires, reduce drought and reverse declining fish numbers we are going to look at two case studies of beavers effects on rivers in two completely different desert regions of north America, one in a northern cold and dry desert zone in Oregon and the other in the hotter and even drier southern desert in Nevada.

Pushing the Boundaries of Fast Charging: New Lithium-Ion Battery Material Can Recharge 80% in 10 Minutes
Electric vehicles (EVs) have revolutionized the automotive industry, promising a sustainable future with reduced carbon emissions. As they surge in popularity, one of the primary challenges has been their charging speeds and battery longevity, which are vital for consumer acceptance and broad adopti
scitechdaily.com
A team of battery scientists recently developed a lithium-ion battery material that not only recharges 80% of its capacity in 10 minutes but keeps that ability for 1,500 charging cycles.
“We found this new electrolyte formulation basically triples the Department of Energy’s target for the lifespan of an extreme-fast-charging battery,” Du said.

Why CO2 Heat Pumps Are The Future Of Cooling. Go to https://brilliant.org/Undecided/ and get 20% off your subscription and a 30 day free trial with Brilliant.org! How can CO2 actually help us keep the planet cooler? When it's the refrigerant in a heat pump! And these heat pumps can warm your house while they heat your water. All while being more than twice as energy efficient as their competitors, at least according to some calculations. So, where has this nearly 150 year-old tech been all my life and why is it only getting noticed now?
Correction:

I was doing some thinking about solar power in Canada during winter, particularly if solar panel prices continue to drop. Placing them vertically on south side of the house or garage, as long as they are not shaded in winter could provide that extra power you might need during winter and could even be shaded by the eaves of the house during summer when the rooftop panels come into play more and aren't covered in snow. For a place like Winnipeg at almost 50 degrees north, the sun angle is less than 20 degrees during the shortest day of the year. So vertical panels would only be offset from optimal angle by a small amount at the shortest day of the year and be snow free. One could angle them 70% for better performance, but vertical is easier and cheaper to install on the side of a house with windows.

A super strong El Niño and record high global sea surface temperatures are set to deliver devastating extreme weather events all over the planet in 2024. They will be extremely costly and traumatic for many millions of people around the world. But the real concern is what the consequences of those events will show us about the fragility and vulnerability our global food supply network is. A worrying portent of our near-term future?

I think this class of EV ( the GM Bolt) could get much better miles/kWh with a next generation battery that doubles the power per kg. Even with the current version if takes 25kWh to go 100 miles. So, if a PV array on the roof on the garage could generate 5kW for 5 hours it should give you the range and a cheap sodium battery in the garage could store the power while at you're work during the day. 5kW of solar panels on the garage roof is not that expensive now considering they could provide 100 miles of free transportation a day. In 5 years, they should be cheaper, better and cheap home sodium battery banks might be available as complete systems.
There are roughly 250 working days in a year and if you commuted 100 miles a day it would cost you $2,500 to go 25,000 a year just to get to work and back for gasoline, throw in some running around and weekend use and you might double that. Infact the average American driver dives over 14,000 miles a year, so on average making your own transportation power would save $1,400 a year compared to gas, but a smaller system would be required to top up the EV every day. Compared to the grid at less than $3/100 miles or $750 per year for the same daily commute, EV charging at home is a bargain. So, if you get a small EV, paying just $750 a year for transportation energy might mean putting in a PV system will not be very attractive until they get cheaper and power rates increase.
www.caranddriver.com
In the case of the Bolt, 100 miles is 38.6 percent of its EPA-rated range of 259 miles. That percentage of its 63-kWh battery pack is 25.5 kWh. In Louisiana, the cost of that 25.5 kWh is $2.81 in electricity to drive 100 miles, when charged at home. Compare that with a 33-mpg gasoline vehicle that would require three gallons of gasoline at the Louisiana price of $3.36 per gallon. That’s about $10, meaning 100 miles in a fairly efficient comparable gasoline vehicle is almost four times as expensive as 100 miles in that Bolt EV.
In Louisiana, for a Bolt EV, 100 miles of home charging is $2.81, and 100 miles of EVgo fast-charging is $11.82; 100 miles in a 33-mpg small SUV would cost about $10.

How Much Does It Cost to Charge an Electric Vehicle?
Few people know what a kilowatt-hour costs them, so they don’t realize how cheap EV home charging is versus gasoline. On the road, it's more complicated.

Innolith to take I-State battery platform to market - electrive.com
The Swiss battery manufacturer Innolith is ready to bring its Li-Ion battery platform I-State to market. Using a new battery chemistry, the manufacturer says it will cut costs and increase range on EVs.
www.electrive.com
Swiss battery cell developer Innolith announced plans to commercialise its I-State platform for use in electric vehicles. As reported in 2019, Innolith relies on a non-flammable inorganic electrolyte for its cells.
According to the new announcement, this enables higher voltages (up to 5 volts) than conventional Li-ion battery cells (maximum 4.2 volts) and an improved temperature range of -40 °C to +60 °C. In combination with a graphite anode and an NMC811 cathode, Innolith says the now commercialised cell achieves a gravimetric energy density of 300 Wh/kg and a volumetric energy density of 825 Wh/L.
The I-State batteries are to be produced within the framework of licensing partnerships with automotive, industrial and battery companies. Innolith plans to announce more details on this at a later date. To support its ongoing licensing negotiations, the company has signed letters of intent with five customers for a production requirement of 100 MWh per year. In the automotive sector, Innolith says it is “working closely with three of the top ten automotive manufacturers and has recently signed a letter of intent with one of the leading electric vehicle manufacturers”.

Why Don’t We Have Solar Powered Cars?
The Truth About Solar Powered Cars.
Electric vehicles are gaining in popularity, but there are aspects of the user experience holding some people back. One of the big things is how long it takes to charge electric cars and access to plug in charging. If you live in an apartment building or the city, plug in charging can get a bit challenging. But what if you didn’t have to use a charger? Some companies have a solar powered car available for pre-order today, but what’s the reality behind these solar cars? Can they really provide enough power to fit the bill, and at a cost that won’t break the bank?
