So Mike, here we’re in the workshop and let’s speak about renewable power methods. The fundamental thing is the embodied vigor. The energy of the manufacturer over the lifetime of the product. Lithium Batteries, they have been included in every single place when you consider that they’re lightweight however they do not last and you fairly shouldn’t have the identical embodied vigor. You then acquired the Lead-Acid battery. The normal battery in cars. However, there is old technological know-how that has an extended lifetime. And that’s whatever no longer many men and women learn about. The nickel-iron battery. So what is the story, what is the nice embodied vigor? And which one’s going to last? Lithium exceptional when you, house problems, or weight disorders. You realize in a caravan, motor home. When you’re requiring a limited area, Lithium is a quality product but it surely’s an extricable product.
Lithium’s going to be the plastic bag of the battery world. So it does not last that lengthy. No. But lead-acid doesn’t final lengthy both and there is an amount of embodied energy in lead-acid. Yup. A lead-acid battery, you know they’re typically the longest, oldest battery on this planet. However, the design of a lead-acid battery decays to give you a piece of it is soul whenever it offers you a little bit of vigor.
So it can be normally going to be consumable. The nickel-iron batteries, after they were first put into the creation, Thomas Edison within the early 1900s, one in each of them the last throes, if he can out survive threes, he’s going to put them into construction. He did that, they powered the first electric automobiles and they’ve made a resurgence into dwelling battery storage. They are saying that some of those electrical cars had batteries 100 years historical and so they’ve taken them out of the automobiles and museums and charged them up.
Now that is what you have achieved, that is what we all know is viable. We had a consumer contact us and say, mate, I’ve received a collection of batteries they had been finally used in 1970, they’re in a paddock, they got slightly of rust on them what do you reckon, you reckon to get ’em going. And I put my hand up said yup, deliver me up. Let’s have a go. One of the crucial batteries absolutely, we validated the exact gravity in the electrolyte. And the batteries had actually nonetheless had electrolyte in them. They were like in best stipulations. The electrolyte simply saved them, made them preserved and lasted longer. But from an electrical point of view, all of it worked electrically. So there are no problems with them. There is simply the ones with the rust holes in the bottom, we had problems with.
So that they got a metal case and the new ones received a high pleasant plastic case. Yup. And it is no longer acid. No. It is an alkaline base combine so that is potassium hydroxide KOH. So they’re heavy and best volts. So you need a variety of batteries and a variety of weight. But rather than that, so stationary in a house, in a building the embodied vigor outmatches lithium by means of 100s of instances? There is no assessment. These are 70 years historical. We haven’t had one die but in five years. So that is the battery if you’re rather seeking to be ethical, and you are trying to have multiplied embodied vigor in a product, that is the battery, all of us should be watching at in residences and buildings? 100%. It is the battery with the bottom embodied the energy and that toughness of the battery of the lifetime, you cannot beat it.
And there are no infrequent metals involved, it is nickel, it is iron, and it is potassium hydroxide? Yup. And the electrolyte when you are finished with it, that you can put it somewhere you wish to have to grow your pumpkins rationale its potash. Right, can develop bananas. There you go, that’s the nice battery to go for if you wish to be ethical and you wish to have to a long-lasting product.
