Saguaro cacti collapsing in Arizona extreme heat, scientist says
Arizona's saguaro cacti, a symbol of the U.S. West, are leaning, losing arms and in some cases falling over during the state's record streak of extreme heat, a scientist said on Tuesday.

I can see car dealers offering a year's worth of free charging on their charging network to spur EV sales.

‘Battle plan’: How the far right would dismantle climate programs
A coalition of conservative groups has assembled a plan to systematically target most of the federal government’s work on climate and clean energy.

Conservatives have already written a climate plan for Trump's second term
Hundreds of conservative operatives outlined a plan that Donald Trump, or any Republican, could use to purge climate action from the federal government.

Any so-called republicans are psychos that Trump gave license to and only a fucking moron would vote for them. There are no excuses, just hate and bigotry driving idiots to suicide, and they want to take the rest of us with them. When their homes are wiped out by floods, hurricanes and tornados they will just blame Biden. Climate change isn't real, Trump won the election and is innocent, the world can no longer afford fact free people and psychos in leadership. Of course, people die every day believing what they want and it's ok, just as long as they don't take the rest of us with them!‘Battle plan’: How the far right would dismantle climate programs

Cheap proton batteries compete with lithium on energy density
RMIT engineers say they've tripled the energy density of cheap, rechargeable, recyclable proton flow batteries, which can now challenge commercially available lithium-ion batteries for capacity with a specific energy density of 245 Wh/kg.

If the gulf stream changes or the AMOC runs amuck we could see palm trees growing here in Nova Scotia and the whole northeast coast of America could warm to sub-tropical while Europe freezes. I live in the northeastern part of Nova Scotia, 46 degrees north, the same latitude are central France and southern Nova Scotia is at about the same latitude as the south of France. London would be about as far north as southern Labrador and places like Scotland and Norway would be around Baffin Island in latitude.

I broke down yesterday and put the AC in the office window, 29 C days with high humidity were too taxing, I have fans, but you still go through a lot of water and salt, and it is generally hard on the system for us older folks. So, after a day in the office much of the time and lots of extra salt I feel much better. The house has ceiling fans and is well ventilated, so it is not exactly sweltering, but it does take a while to cool down at night even with outside temps falling to 20C. It is a comfy 24C in here now and outside it's 27C, 34C with the humidex taken into account.
I figure it's gonna be a long hot summer so rather than not bothering with AC this year I figured it would be good for health reasons and it has given the old body a good rest and some relief.

The Chevrolet Bolt EV Is Coming Back. Here's What We Know (and Hope It'll Have)
11,721 views Jul 26, 2023
Earlier this year, General Motors confirmed that the Bolt EV would end production at the end of this year - and we, among many others lamented the loss of an affordable electric vehicle that wasn't a massive SUV or pickup truck.
But earlier this week, GM CEO Mary Barra confirmed that the Bolt EV will return as a Ultium-based model.
Here's what we know (not a lot), as well as some of our speculation on what the next-generation Bolt EV should be like.

Even if they don't use these in wheel hubs, it still makes sense to use them for weight, space and material savings in EVs, they look cheaper to produce than radial flux motors too, once they gear up to do it. One of these powering a compact EV, say about 60 to 100HP, could be very small and light.

When I see a steady source of power like this or hydro, I think the number of customers served per megawatt generated could be doubled or more with grid scale storage. Most of the time our house uses little energy except for peak periods when heavy loads are required by many at the same time, like in the morning and early evening, times when power can be stored in batteries. Grid scale batteries will do a lot to increase grid efficiency and its ability to handle peak loads, as well as storage for intermittent renewables.
The results: According to the company, the pilot test set two new records for an enhanced geothermal system, with a demonstrated flow rate of 63 liters per second and a power output of 3.5 MW, which is enough to support about 2,600 homes.

No other enhanced geothermal system can output this much power — and they’re just getting started.

These projects are in the Great Basin, a terrain formed by tensile rupture of the lithosphere. If they drill at the “lap joints”, they access shallow hot rock not available elsewhere. I’d be impressed if they drilled in Wisconsin.

I think we will need every clean energy source we can get our hands on to make it. If we can decarbonize transport, cement and steel making we would be well on our way to a brighter future, the technologies exist to do it and are constantly improving.

I agree that increments matter. But starkly missing from the article is the viable lifetime at high power draw of the proposed boreholes.
It’s quite similar to the concern about projects to drill very deep for geothermal energy. If each bore yields a few terajoules before falling off the power economy curve, it’s pie in the sky.
Sorely missing from these speculations sourced from the sales pitches by interested parties is the worst-case analysis.
“Here is the worst combination our model (or better, a conservative open-source model from unaffiliated university geology teams) predicts, and here is the revenue stream under those conditions.”

It could be these bore holes can be cycled, shut down for a time while the rock heats up again. Several holes could be used spaced miles apart and the power plant can switch to a refreshed one when the one it is using drops off, but it would drive up costs by a lot if this was required for any more than a couple of holes per power plant. I think the deep you go the hotter it gets, and the less likely power will drop off over time, but deep geothermal needs new technology that is being tested now by companies using several different drilling approaches.

I’ll wait for proof of both concepts: technical and financial. I am less entertained than you by vaporware.

We are going to need everything we can get, so if serious people are giving it a go, then it is worth a look and spending a few bucks on if it makes sense to do so, a fraction of what is spent on fusion would do.

Sure.
It remains my opinion that speculative balloon juice/futureporn of the sort that fills the pages of Popular Mechanics is an irritating diversion from the more fruitful question “what can we do with available or proven resources in the here and now?” Such as the recent reporting on why solar evaporation shades for open aqueducts are a tougher proposal than one might imagine.
