Have a look at this. Watch to the end. Might be the replacement battery for the Lithium batteries.

 

 

So much click-bait with battery technologies - it is not really worth even discussing until you can actually buy them.

True that, but just for interest sake I posted this. 😉

The age old Edison Nickel-Iron batteries will last a life time. Probably the best battery technology still. You can do some research on it. Only thing you need is space, lots of space.
 

The the 80s, cold fusion was supposed to be soon the solution to all energy problems... still waiting for this to happen...

Unfortunately that time, there was no YouTube for clickbait videos...

There are plenty of "new" battery chemistry's coming out atm, even a few old one's are making a comeback (Lithium Iron), seems everyone's getting in on it (and their cousin). My view is its a very good thing, many wont make it past the lab stage, a lot seem promising, if overly complicated in conception.

My favourite atm is the iron flow battery, the basic components are in great supply worldwide, non toxic, zero degradation over 20,000 cycles. The battery is made of iron salt and water. So also super cheap to manufacture, recycling is a breeze.

if used in ev's an interesting concept is "charging" will simply involve "swopping" out your electrolyte rather than charging as we know it, making the process much quicker in theory. whether it will make it into ev's is an entirely different conversation.

It's currently being put into grid size installations, so also out of the lab and into the field, with specs and performance that have convinced the guys that sign the checks to go ahead with them, rather big checks.

From what I can tell, the trick will be to create a cost effective small form factor home size edition, 10kw-30kw, at the moment they come in 40ft containers.

In the next 5 - 10 years, my view is main stream home energy storage will have some kind of flow, and not just electrons either.

@Nitrious I also checked those out. Sounds promising but the costs involved is a big question. What they say is "cheaper" is definitely above my pay grade  and many others. All the other click bait wannabees  about free power/energy is a lot of BS. There is no such thing as "free" energy. (besides the sun, wind and water - which still require a lot of money and effort to harvest from those elements.) I have tested a couple of these "free" energy ideas out of curiosity (and for the laughs) but debunked them and all failed miserably. Most of them doesn't even follow the natural "laws" of electronics\physics etc. etc. and most of them just plain BS.

Just my 2 cents. 😉

Yeah, you need a swimming pool of electrolyte to get to 10kWh with iron flow. There is no way around that - so you are not going to reduce the form factor unless it coincides with a fundamental change in physics as we know it...

I always enjoy a good free energy video, the ones with the fans in the background, or hidden battery terminals or whatnot. Of course its junk, but sometimes the videos that come suggested aren't bad.

My latest tryouts are

low temp differential sterling engines, this lead me to dig out a lot of usa doe and nasa research from around 1976- 1986 on sterling engines. These look cool as desk ornaments, and run just fine on your morning coffee.

Another was the Mendocino Motor, not much use, or even practical, but again looks cool, and if you really want a fan that doesn't use grid power.

The hydraulic ram pump featured as well, not bad if you've got the running water and a bit of height.

An odd one actually in use is the archimedes screw pump generator, weirdly it seems to be big in japan. Again it works, you need running water though.

water desalination using solar and without the crazy brine concentration.

I do have an iron flow design that in the works, and which likely wont break the bank, Its very much in its infancy, so no promises, eta's or details on anything here atm.

I also found time to fit in a bit of astrophotography, but that's still a work in progress.
