Want some #verisimilitude for your post-apocalyptic story? Four years after the pandemic started, 7 out of 7 examined #battery-powered candles had burst batteries. 3 out of 7 had destroyed circuitry and were irreparable. I restored four of the candles to working order with a lot of cleaning and scrubbing, but of course they required fresh #batteries.
Takeaway: Nothing battery-powered left for four years will work when found. Much of it will be destroyed.
Bonus: Gasoline has a shelf life and may be useless in 6-12 months. Sorry, no verisimilitude in Mad Max.
Could the National Grid be making better use of the battery storage facilities already available in the UK?
It seems that at some points in the last year, even when there was battery-stored electricity available to be drawn down, the Grid still used gas-fired additional generation instead.
Its likely to have be caused by a lack of up-to-date computing infrastructure to manage supply during surges.
We have a net-zero friendly solution but are (still) not fully using it!
Was checking out some reports about the DRC and found this piece by the NPR. Just another "detail" western organizations pushed under the rug when talking about clean energy solutions.
Cobalt is mined using basically slave labour. The mines polute both soil, air, and water. Although nowadays we have a lithium battery type (LiFePO4) without cobalt, it's still used, and also in e.g. alloys and gas turbines.
… ummm, is this battery bulging??? I’ve never had that happen so I’m unsure what to do here. It feels… a lil spongy. Do they have a slight foam barrier orrrrr
If you're interested in learning about how car battery safety has evolved, then I'd highly recommend watching this video. They also cover the differences in quality and construction standards between the batteries for an ebike vs a car.
According to a report by BloombergNEF, it is estimated that by 2030, there will be around 1.2 million tons of retired EV batteries worldwide.
Researchers at Oak Ridge National Laboratory have developed a new technology enabling EV battery reuse: a type of power electronics equipment that can manage a variety of EV batteries as an energy storage system for an electric utility.
lowtech magazine had a pretty good write-up on theirs. the flywheel sounds like an important element.
Of course, it sounded very complicated to match pedaling speed and intensity to the needs of a battery or load. I would think a charge controller would eliminate all that and just put the available energy to use appropriately.
“It’s not green, it’s greed. Global warming is a serious problem and we cannot continue burning #fossilfuels, but destroying mountains for lithium is just as bad as destroying mountains for coal. You can’t blow up a mountain and call it green.”
#Barroso is the only region in #Portugal – and one of only eight in Europe – recognised by the Food and Agriculture Organization (FAO) as a Globally Important Agricultural Heritage System of outstanding landscapes that combine agricultural biodiversity, resilient ecosystems and a valuable cultural heritage.
So you probably haven't heard since it's not angertainment, but one of the largest economies in the world has produced 100% of demand from #Wind#Water and #Solar over the last two weeks.
Imagine how much money the people with #batteries are making now while they are getting paid to recharge AND getting paid to discharge them in California!
"#OakRun will be #Ohio’s largest solar installation and the nation’s biggest #agrivoltaics project, spanning 6,000 acres and totaling 800 MW. It combines farming and solar generation on the same plot of land, and includes a massive array of #batteries.
It is estimated that the project will generate $7.2 million every year in new #revenue for the county and surrounding townships and school districts over its estimated 35-year life."
Can you safely revive a dead lithium-ion battery? Yes – here’s how
More and more devices now come kitted out with rechargeable lithium-ion batteries — you know, the ones that look like the old-style AA or C cell batteries, but are a slightly different size. The most common size is the now ubiquitous 18650, but ther ...continues
#ScienceDirect and #Elsevier clearly didn't review this #chemistry paper about #batteries. The intro starts with "Certainly, here is a possible introduction for your topic:".
This lack of oversight erodes #trust in #science. The paper needs to be retracted and the authors sanctioned immediately.
"The cathode is not made from the familiar mixture of #lithium and other metals. Instead, the primary ingredient is #zinc, which ranks as the fourth most produced metal in the world.
Eos’s batteries use a #water-based electrolyte (the liquid that moves charge around in a battery) instead of organic solvent."
This is intended to be a #GridBattery.
"The recent price cuts come from a deliberate decision to use abundant earth materials such as iron and phosphorus wherever possible.
These #batteries are cheaper, as they have no #cobalt. They have other benefits too: a longer usable life and less risk of fire than traditional #lithium battery chemistries. The downside is they have lower capacity and voltage."
