I am really glad to Tom for showing us this hidden gem. It's a real shame that it slipped under my radar for so long. I have some catching up to do :)

Batteries don't need to be made with lithium, and mining lithium isn't that big of a deal when compared to the extraction of fossil fuels.

It's amazing how much effort you obviously put into your videos. It's criminal that you are such a small channel. Your visuals are amazing, both the footage and the graphics. However, one thing I'd recommend is getting an external microphone and a greater focus on editing audio. Not that your audio is terrible by any means - it's hearable, clear enough to decipher what you are saying, and not particularly grating or anything - but people are far more likely to tolerate average visuals than audio because it doesn't affect the enjoyment of the video as much. If the visuals are bad, people are annoyed. If the audio is bad, it becomes unwatchable. Your audio jumps around a bit. Clicking on the video, different segments sound completely different (take 1:29 compared to 1:36, yet the visuals are rather consistent. But honestly mate, your videos are so interesting and your scripts are succinct and informative. Keep on going mate!!

You don't need a very big battery, just big enough that you can cover the demand for sure for long enough to fire up the diesel generator if needed. Seemed a shame to just waste excess energy as heat.

Actually plenty of water for hydro storage available, you could also set up a big tank

@sirsanti8408 Жыл бұрын

I think the biggest problem with using lithium batteries as grid storage is that the reasons lithium batteries are great for phones, cars, laptops, etc… are useless or completely unnecessary for grid storage (being relatively light, compact, not sensitive to any movement) lithium batteries are also extremely expensive. For grid storage you’d want a battery that’s relatively cheap and doesn’t degrade over time like a lithium one would.

Thanks for making such nice videos! I don't really understand the water hose equivalent here. With a traditional turbine generator connected directly to the grid, a decrease in demand would simply decrease the mechanical resistance on the input shaft, allowing the turbine to spin faster and faster. This would damage both the generator and the connected devices. How is this the case with solar panels and wind turbines? Solar panels don't have any moving parts, so disconnecting some or all of them from the grid doesn't lead to mechanical issues. Wind turbines usually have brakes and the ability to change the blade pitch. What prevents this from being used here?

@jobamay5740 Жыл бұрын

Nothing, but you have to adjust for it. You need a system that disconnects panels or changes blade pitch. To keep the analogy going: you need a system that acts as a valve at the start of your hose in order to not break the hose

Little known fact: they are called wind turbines, because the turbine is winding its way around an electrical generator, as the air is blowing over it.

Exactly and in storage batteries can be just old EV batteries, because most of them are 70% of original capacity still and can last more than decade of storage usage still and if that is just alongside with those other energy storage things, then stoarge capacity doesn't need to super massive. I don't know how much that resistor waste energy, but that could be saved with batteries and the resistor would be just backup if batteries fill up. Additionally there could be EV charging station near that battery storage thing, and maybe if batteries are more than 70% full (of working range) or something like that, then EV drivers could charge free there (I know that EVs don't use much energy, but atleast that energy would go to good use and not just heating up air.

You got that backwards. If too much energy is being produced you'd reduce the resistance as power consumed by the resistor is inversely proportional to the resistance, P=I^2/R.

@massimocole9689 2 жыл бұрын

You have that backwards, the law is P = I^2*R. That's why conductors with low resistance are valued, because they lose less power to heat. High conductivity means low resistance. en.wikipedia.org/wiki/Electrical_resistivity_and_conductivity

@unchosenid 2 жыл бұрын

@@massimocole9689 You are correct Sir! P = I^2*R! It's been 40+ years since I was involved in electronics..... You are incorrect though in one thing; this power load is designed to suck up power, not avoid sucking up power as in transmission lines. If you want to maintain the same voltage on a line, and yet suck up excess power being created, you need to reduce the resistance of your variable load resistor. Thus creating more I. Halving the R will double the I and assuming the V remains the same it will quadruple the P. Contrary to what the video said. So paradoxically, I was right, and wrong :). Power consumed by a circuit is inverse to the resistance of that circuit, assuming V remains the same. Sometimes it takes a few moments to clear the cobwebs. I just knew that to absorb excess power on a powerline that must maintain a constant voltage you have to reduce a control load resistance. I just got the formula wrong... :)

@massimocole9689 2 жыл бұрын

@@unchosenid Ok yeah, I also saw the equation P = V^2/R when looking that up so that seems to track. Is that because if voltage is constant the lower resistance results in higher current flow, and the higher current flow also heats up the lines? It seems kind of counter intuitive that R can be both inversely and proportionally related to power loss depending on the situation, how do we know which one applies in this case?

Dismissing batteries is not smart. Even if you don't use them we need more of them and you are discouraging people from considering them on false grounds. Why not compress air as energy storage?
