Global warming pushes ocean temperatures off the charts: study

In 2023, the world's oceans took up an enormous amount of excess heat, enough to "boil away billions of Olympic-sized swimming pools," according to an annual report published Thursday.

90-seat Elysian airliner: 800-1,000-km range on batteries alone

A Dutch startup says everyone's hugely underestimating the potential of battery-electric aircraft – that it's possible to build large battery-electric airliners covering distances most assume we'll need hydrogen for. Elysian plans to prove it.

Wimbledon: Electric buses withdrawn in south London after fire

A fleet of electric buses have been withdrawn as a "precaution" after electric bus caught fire.

www.bbc.co.uk

Strange how after all the dozens of diesel bus fires with total burn outs in various bus designs, none was ever withdrawn from service. Electric vehicle hysteria again?

This e-bus in Wimbledon was an Optare Metrodecker, a model that has been in service for five years now and 84 of them have operated on 14 different routes. This is the first fire in one of this make and model while in service.

I think they can happen, but it will mean a set back in time to very slow flight speeds, maybe 200 mph at most. Boring enough to be pleased thay can't fly very far. And just as we've moved away from any airliners with over two engines, it will be back to engines all along both wings!

Quaint.

A little birdie told me that some of the diesel vehicles that burst into flames sometimes turn out to be battery vehicles. Just saying!

And I've several times over a long period shown the photos proving that they were not. Many of them were from before our battery e-bus era anyway.

Regardless , we are going to EV buses only anyway, simply because we have to for multiple reasons, so protest and opposition is foolish and pointless. The latest news on climate change is proof enough of the necessity, and the thousands killed prematurely by pollution now, including proof of young children too, really leaves no other option.

As with all new tech having intrinsic risks, we'll find ways to make them safer and more reliable. We've achieved that with our hydrogen fuel cell buses and we'll get there with the lithium battery ones. It just takes time so needs some patience.

A Dying StarEventually, the fuel of the sun - hydrogen - will run out. When this happens, the sun will begin to die. But don't worry, this should not happen for about 5 billion years. After the hydrogen runs out, there will be a period of 2-3 billion years whereby the sun will go through the phases of star death.

oh well hurry up its fkn -2 outside

Those ones had lithium 12v batteries in them - big ones.

they cost a fkn fortune as well

light bulbs cost more tho

Pardon our interruption...

bet you could get some good bush going with those and low powerd controllers

cold days

It's cold toe weather again, and my toes are always cold even when my home is warm... so ....



...is powering this... (had to solder an inline blade fuse because I didn't have a fuse holder)



...which is inside a sleeping bag covered by this...



...covered by this, because that foiled mylar stuff is flimsy...



According to my new Neoteck DMM's thermocouple, it's nice and warm inside the sleeping bag...






My toes are bloody warm, feet sweaty until they dry out completely lol - this is actually an indoor test for winter post-gardening warm-up pre-cycle back from my off-grid garden; powered by my ebike battery.



Unsure if it'll be warm enough for 6 degrees C or whatever outdoors, so I'll pack a couple of hot water bottles and boiling hot water in Thermos flasks to fill them with, for added warming-up power before the 12 mile ride back.

The 'Startling' Link Between Low Interest Rates and Low Crime - The Crime Report

When interest rates go up, crime goes up. When interest rates go down, crime goes down. Two analysts say the powerful relationship between them has significant implications for justice and economic policymakers in the next administration.

Chinese Betavolt plans to start mass production of its atomic battery BV100 now.
It's based on nickel-63 which has a half life of 100 years, safe beta decay to copper, suitable for medical use.

Quote:

Betavolt says its batteries can meet the needs of long-lasting power supply in multiple scenarios such as aerospace, AI equipment, medical equipment, micro-electromechanical systems, advanced sensors, small drones and micro-robots. "If policies allow, atomic energy batteries can allow a mobile phone to never be charged, and drones that can only fly for 15 minutes can fly continuously," it said.
The first battery that the company plans to launch is the BV100, which it claims will be the world's first nuclear battery to be mass-produced. Measuring 15mm by 15mm and 5 mm thick, the battery can generate 100 microwatts, with a voltage of 3V. The company plans to launch a 1-watt battery in 2025.
Betavolt says its atomic energy battery is "absolutely safe, has no external radiation, and is suitable for use in medical devices such as pacemakers, artificial hearts, and cochleas in the human body". It adds: "Atomic energy batteries are environmentally friendly. After the decay period, the nickel-63 isotope as the radioactive source turns into a stable isotope of copper, which is non-radioactive and does not pose any threat or pollution to the environment."

Is that on a Q plate?? Lmao

Raynaud's?

No thanks I'm trying to give up. Just bad circulation, especially when blood sugar is low. I was prediabetic before losing over 3.5 stones, had very high blood pressure and inflammation markers, but not anymore according to my state certified quack... I don't do enough exercise, I'm no longer young, and have about 9lbs left to shed - this last bit is taking ages.

Right now my toes are well toasty. This is bagged electro heating is a keeper for sure, and not just for the garden - I haven't needed to burn money using my central heating for hours.

Is that on a Q plate?? Lmao

The front reminds me of the Aston Martin Lagonda.
