One of the problems of switching AA batteries to a different chemical is the voltage that they give out. Alkaline batteries give 1.5 V. Rechargeable batteries like NiCd (low capacity) and NiMH (much better capacity, but still less than alkaline) give 1.2 V out. This is OK most of the time. For devices that need high current like a handheld printer, rechargeable 10 to not give out enough current. The problem comes with different types of lithium batteries, they give somewhere between 3.6 and 3.9 V. If you put four of those in a row instead of 6 V, you will have 14.4-15.6 V. This will probably fry your device. Rechargeable lithium batteries really shine when they are built into the device. Most of these can also be made to be exchanged. The devices that we build in the company where I work, the rechargeable lithium ion battery usually outlives the device itself. If for some reason it doesn’t, it has a connector on it so it’s just plug and play.

Where I live Ryobi have standardised their rechargeable batteries for power hand and garden tools. Commercially it has been hugely successful for them. Not so well known, adapters are now readily available that allow other brand power tools to be operated using the very reliable Ryobi interchangeable portable battery system. I have a number of these inexpensive adapters that have resuscitated a number of older power tools enabling them to run on Ryobi batteries, I would otherwise have had to bin.

20:00 User feedback from users directly is also useful and I think they listen, especially on the experimental features. Many months ago RUclips was experimenting with normalized audio volume (see DRC) which sounds mostly fine on spoken audio, but screws up music. Whenever I loaded up a music video and audio was off, I immediately used the report function. It took a couple of weeks for them to stop. You may have noticed a new setting in the player "Stable Volume", and it's more consistently off on music.

Hello! Thanks for a great podcast. I want to share two examples from my neighborhood Västerås (no, unfortunately not Westeros from GOT) in Sweden. The first is from the city of Västerås, where the local energy company has converted a old man built cave from being an oil depot to being used as a hot water storage. It is heated during the summer with surplus energy from the power plant that generate electricity and heat by burning household waste. The hot water is later used during the winter to heat the city. Search for bbc mälarenergi underground hot water bottle and you will find an article. The other is from the northern parts of the county which are full of old abandoned mines. There, tests are with energy storage, which involves pumping up water from the bottom of the mines to a higher level using excess energy from wind turbines and then releasing the water and generating electricity when needed. Search for minestorage to get to the company's website. They have good descriptions of how it is done. Worth mentioning is that Sweden has more than 98 percent fossil-free energy, where 40 percent comes from hydropower, 30 percent from nuclear power and 20 percent from wind power. Best regards, Per Lithén (pronounced Pear lit-in)

I haven't done this, but I reckon it'd be somewhat simple to create a user script to 'automagically' change to the preferred language (English in this case), and also remember it. I'm not entirely sure it would work in Chrome with Google's recent changes in how scripts can interact, but it should work in Safari/Firefox.

There is problem with cheap batteries in vapes causing fires at recycling centres.

Super cool.

With the new tech being produced to scale, it is cheaper and faster to implement the new tech than to bother considering the old.

While I do understand that there is plenty of content especially every day that passes in pretty much any major language that is on the internet... 1. English - Around 60% 2. Chinese - 15-20% 3. Spanish- 8-10% 4. Arabic - 5-6% 5. Portuguese - 3-4% 6. Indonesian/Malay- 2-3% 7. French - 2-3% 8. Japanese- 2% 9. Russian - 2% 10 German - 1-2% (according to gpt) So it would make since that the more of that language on the internet the more places they could collect data from to make them better. Granted that means they should have just released it in the top three or four languages on the internet which would be extremely helpful and they could have easily said, hey there just isn't enough of those languages in the internet. Although we have decided X million to help put historical documents/books/other content online in those languages to one give people in those areas and information boom but to also jump start the ability to translate into them more accurately using these new technologies. It would be barley seed money, I am sure a few million could cover a lot of scanning of old libraries... Even if it is older version of the language if it is shown a reasonable amount of modern text with the information of when it was created, the it can follow the evolution of languages too.

Hopefully you won't have a lawn mower in 10 years. Hopefully in 10 years everyone has yards that are actually healthy for the environment and not just look nice. Hopefully they can look nice and to be environmentally conscious.

One thing that you probably look into is USBC batteries. It's not a limitation of the technology or what people are willing to spend whenever you don't need batteries often so therefore unless you absolutely need them in the moment and you just don't have those few extra dollars... Especially with the USBC ones every time I show someone that I have USBC chargeable batteries they put it in their Amazon shopping cart list and save it for whenever they have the money to buy it or buy it right then and there.

Also that's part of the fight to right to repair. In battery replacement/recycling should be a part of that process. Even for small tech. Obviously for nanotech that's always going to be an issue but you know there's a difference between the bleeding edge and something at least within the realm of what we currently have.

I mean headphones do recharge.

Here is chat GPT's take on The small scale use of compressed air batteries over the next 60 years expressed in a percentage chance. Here’s a rough estimate of the likelihood that compressed air energy storage (CAES) will become feasible on a much smaller scale over different timeframes: - **Next 5 years**: 5-10% - Limited to niche applications or early experimental models. No major breakthroughs expected. - **Next 10 years**: 15-20% - Some advancements could make small-scale CAES more viable for specific uses, but it likely won't be widespread yet. - **Next 20 years**: 30-40% - New materials and technology might improve efficiency and cost, making small-scale CAES practical for certain markets. - **Next 30 years**: 50-60% - Moderate chance of adoption for specific uses, especially with advancements in energy efficiency and heat management. - **Next 40 years**: 70-80% - Significant likelihood, as technology evolves and scales down further. Small-scale CAES could be more common. - **Next 50 years**: 85-90% - Most likely to be practical for many small-scale applications, especially with ongoing advancements in energy storage technologies. - **Next 60 years**: 90-95% - Highly likely that small-scale CAES will be efficient, cost-effective, and used for various purposes alongside other energy storage solutions. Take that as you will. 😅

A tank of compressed air is not always as safe as what you assume. Many people have compressed air for various purposes, such as running air tools or inflating tires. Sometimes a tank will have a catastrophic failure. When such a tank ruptures under pressure, it can release energy like a small bomb. Such events have destroyed property and injured and killed people.

I read recently that one of the enhanced geothermal geothermal companies are testing pumping air into the fractured bedrock around their Wells and are able to store many hours of compressed air I don't think they had really gotten to the heat recovery aspect even though the wells are supposed to be heat recovery systems

There's a lot of different battery technologies out there, and I think we may just need them all. The key will be which technology is "best" for which things. None of these energy storage systems is good for every application. So it would be great if we could sort out which ones are good for which things and apply them to those things, while applying other means of energy storage to the things that technology doesn't work so well for.

One HUGE benefit of the AA and AAA batteries is the ability to store them long term. When I lived in Southern California, I had multiple packs of those small batteries packed in my earthquake kits. Why? Because they are shelf stable for YEARS. No need to have a charger, or access to mains electricity or a car (with fuel!) to recharge. I just open the pack of batteries, put them in, and good to go. No rechargeable battery has that ability. Plus, as you guys hinted at with respect to lawn mowers, etc, they are a standard form factor. I have an EcoFlow 1600 watt/768 Wh battery pack for emergencies, but I have to remember to top it off occasionally. I also have our fiber modem/router on a UPS, but that thing is sucking down magic pixies on an ongoing basis (a minor cost, yes, but it's there, and it has a shelf life as well) I think a cross-ecosystem battery configuration is a necessity. I realize that Ryobi, DeWalt, Milwaukee, et al, don't want that, but it's still a dream I have. All hail the mighty dollar! This is your god... (obligatory They Live reference; "I came here to kick ass AND chew bubblegum, and I'm aaalllll out of bubblegum. ")

Probs shouldn't tell the general public when you won't be home.

Yes , ditch de dubbing! its terrible! .. worst is that when you AirPlay it to Apple TV you can't force it to English no matter what I do!

I liked the conversation, I think Matt might have misspoke talking about scales (1MW, 100MW, 1GW, etc) for compressed air vs batteries. Maybe he meant MWh, and GWh there , not MW and GW. Where these alternatives to batteries shine is in storage capacity, NOT generation capacity. That's the whole point, in fact. If you were to try to take a 1 GWh compressed air storage system and have it produce 1 GW, it would not be economically feasible any more. But if that 1 GWh of storage has 10 MW of capability, it would. Same with flow batteries and other technologies. Please remember again that the cost of battery storage is NOT the only factor when it comes to deciding what kind of system to get. I can't say this enough times, but BECAUSE of their relatively higher power ratings, battery systems can remove the need to expand or run new transmission lines in congested corridors. One of the big economic reasons for building a new battery system is precisely to situate it in a congested corridor to avoid those other costs. Like a 2-for-1 deal if you think about it. ESS makers are not unaware of this factor and some are now offering shipping-container battery systems with inverters and also without inverters (battery expansion only) in order to chop off more bits of the pie from other higher-storage-capacity technologies. -Matt

This, like those carbon thermal batteries, also seems like something that could be progressively installed at existing power stations as parts of them get decommissioned. As they are also usually far away from housing you could use the same land for wind (if suitable), or just cover all the no-longer-fume-producing buildings in solar.

I would like to know about the space requirements and the cost to run ? A Big Battery system takes a fair amount of space and there is "Basic" maintenance and safety work to keep it going, what about a similar capacity compressed air ? In Australia we are building a new Big Battery in Melbourne 1.2GW/2.4GWh on a 90Hectare site

There are rechargeable lithium AA batteries, with USB-C sockets in the side! Not super common, but they should be.

An important factor is the TCO. A system that requires mechanical conversion (aka generators/compressors) will have higher maintenance needs than a system without moving parts (aka electrochemical batteries). Fewer moving parts generally means higher reliability and lower operating costs... generally.

I wish it would actually default to my language. On my Chromecast with Google TV, it turns on CC kinda randomly all the time (I set it to no CC) and what's worse: it turns it on with random languages, Italian, Korean, Spanish,... If I get lucky, it's German or English....

Dubbing .. I'd say don't do it until google fixes their UI. Just because I live somewhere doesn't mean I speak the language. It's good enough heuristics for ads because ads get arguably better if you don't understand them, but it's a terrible heuristic for a preferred language, especially in a world where every browser already has a preferred language setting. And hell, you always lose something in the translation. I don't even read translated books when I know the original language, why would I want to do that to videos? Great for kids though.

Compressor is a machine that makes 90% heat and 10% air. So effectively this is a hybrid heat/compressed air battery that would store heat with a byproduct compressed air. Being n the compressors business for over 20 years we offer energy recovery options for more and more units sold these days.

i am not struggeling with the translation, but i always switch to english because the translation is poor and the jokes and wordplay is totally lost in translation

I had a friend passionate about history painstakingly translate videos from The Great War in french back in 2015 for his father that didn't speak any english back when community captions were a thing. He was frustrated even back then because some videos had french subtitles already but they were full of mistakes and didn't understand the material covered. It smelled of a google translation or some french guy removed from the context of the video, just listening to the audio and translating word by word basically. For whatever reason it supplanted the work he did and just prevented him from getting the correct captions. There were problems even back then and eventually they just deleted the feature instead of fixing it, like allowing multiple captions or... anything really. Quite Google like in hindsight. I have no faith in whatever they're trying to do here, they have repeatedly shown they have no idea what they're doing and what enthusiasts are looking for. Maybe I'm out of touch compared to the lowest common denominator that just wants to mindlessly consume videos in their language, I get that, but it's not like I don't get to complain just because I'm in the minority.

The graph of compressed air vs lithium ion shows that private lithium ion battery companies have an incentive to prevent governments/collectives from supplying grid infrastructure along with massive air batteries to power entire cities/communities in favor of decimating public infrastructure, privatizing batteries and selling them to individual households instead, much the way from its inception big auto and oil lobbied against high speed rail and public trans. This illustrates a universal issue that collectives operate more efficiently than competing individuals.

Very interesting 👍

As an off-grid climate mitigation device, I imagine a heat pump that runs directly off solar with the minimal electronics. Just a minimalist survival device. For whatever bonus storage, use a thermal battery, and a relatively small electrochemical battery. If America wants to vote against the Energy Transition in November, maybe the Global South becomes worthy of talent and capital resources.

Stop 🛑 talking about energy storage and start talking about a power line run to Australia 🇦🇺 to America 🇺🇸 to Europe. Install solar because it’s the cheapest power plant to build problem solved !!!!! We already have billions of miles of Uber sea cable for inter it is time for power cables

For those interested in compressed air and related ... I have heard of a company that is looking to repurpose pipelines to store compressed air (long duration). Also, there was a company focused on capturing energy solely on the variations of pressure in the existing gas pipeline network. Very nerdy stuff, if completely impractical. 😄

I am italian, but due to several American platforms, apps and sites doing this terrible auto-translations, now my computer, phones, and all my accounts are set in english.

Universal 40v... 3000amp(exaggeration)! too bad for your leaf blower...

Great information as always

Like cameras and V-Mount batteries!

Adding heat to compressed air doesn’t release energy, it IS the energy. There is no stored energy in compressed air. The energy is the heat and compressing air releases that heat energy, it doesn’t store it. All compressed air batteries are thermal batteries, or they aren’t batteries. In other words, if you don’t store the released heat when you compress air, you have failed to store the energy.

There is actually an EU legislation coming into effect that means all powertool manufacturers have to use the same standard interface, starting with having to sell adaptors for their existing platforms.

I live in the Netherlands and still get your video's in English, i tested the dutch, but didn't like it and went back to originaliteit without any problem

As a keen amateur photographer I find the more expensive rechargeable batteries well worth the extra, they are less prone to self discharge, and when one has 8 external, and 4 internal AA batteries per flashgun plus spares, it’s important to arrive at the job fully charged devices. My biggest limitation is only having 24 charging slots.

Planned obsolescence of cell phones by battery degradation, there are quite a few shops to replace cell phone lithium batteries now and has been carried on to high and home devices such as Bluetooth speakers. Too expensive devices should have interchangeable batteries. US federal law mandated power tool batteries the replaceable years ago. Most likely due to EU mandate that mobile phones have interchangeable batteries by 2027, America will see the same law affecting their phones.

I have seen some people who release multiple videos.. one "English" or Japanese or Korean and then a second on as multi lingual. I do not know what it would do to your views or release schedule or whatever.

on amazon 24 count Duracell $16.43 (0.68/count) Energizer 15.66 (0.68/count) Amazon basic 16 pack rechargeable 17.59 (1.10/count) so yes 2x initial price but i have done more than 200 cycles and still going strong. iIt seems the same as EV's more expensive at first but the recharges save you the money quickly.

thank you, prevent effect of global warming, New energy from sea will change world soon, minerals and temperature of water and air from sea are huge source of energy, reduce more than 50% using fossil fuel, fresh water, fertilizer(minerals+O2,N2,C), zero pollution by using power magnet of machine to separate N2 and O2 from Air , economy will rise by using jet plasma machine and compressed gas(Air) in isolated structure in water pool with more than 80 % efficiency, it has two vertical cylinders, in first level it transfers compressed gas(hot air) temperature from engine to sea water in pool for steam electric generator, steam combines with high cold Air pressure to produce pure water and electricity , there are other source of energy that with international cooperation in coastline we can reduce effect of global warming, further more we can prevent these phenomena like cyclone and flood and wildfire by using this hot seasonal atmospheric condition, recent years in summer, geothermal energy happens in surface of coastline, there are many countries in coastline with seasonal hot weather and water condition in comparison with middle Ocean, its more than 12 degrees ,this differences must decrease, in sum-up, by using this energy not only is economical but also reduce global warming in countries like Japan, China, India, Mediterranean countries, Iran, Brazil, Mexico, Us, Canada, (Africa and Arabian countries....) . I invented new method base on air pressure rules and quantum physics ionization sea water minerals in strong dynamic permanent magnet(SMCO) with special frequency(1500or 3000)/minute bases on paramagnetic and diamagnetic particles and electrical microwave electron wave field and electric chemical reactions and photon wave from semiconductors with special angle Cations like(K+, Mg++, Na+, H+, H++, li+, H2, ...) are transferred to in the second level into up level by vacuum pump from storage into combustion chambers and they combine with O2 and N2 ,... as major part of fuel, they increase speed of machine, modern induct Gearbox to control speed of opposite direction, for producing electricity and fresh water (removed minerals by accelerate ionization sys from sea water) and fertilizer. this machine produces 150Megwatt/hour and 20000M3/DAY fresh water and fertilizer. 7 methods zero pollution for reducing global warming I mentioned in my profile. (G20 countries can solve these phenomena).

there are many individuals that do their own microgrid because connecting to the macro-grid is so expensive. One RUclips couple, Adventure Strikes channel, in northern Idaho has done this. If it cost more than about $10K to get power delivered to your sites, building your own microgrid for about $20K or so is cheaper and you have no 'monthly charge' in addition to energy use.

On small batteries, there are good small batteries. In the small drones have small replicable lithium batteries. They are available, and chargers are available, but you MUST engineer for it. The small batteries have the same charge curves as big batteries (voltage and current requirements). The drone packs are swappable.
