Yes, thermal storage; not trying to get electricity back.
I realise that phase change isn't free. That's fine.
So fridge/freezers don't have a reservoir of liquid refrigerant? I hoped that the compressor turned on every so often to fill the reservoir which would then slowly be released into...
Thanks for responding. You'd be deferring energy usage to when it was cheapest or when your solar panels were generating power. Obviously you couldn't efficiently use this to run your PC. You'd use the compressed R134A to cool the inside of a refrigerator/freezer. It would be better than...
How much energy is used to compress e.g. 0.8 Kg (typical mass in a typical fridge freezer; edit: I've just seen that 0.8 kg is not normal at all; it's more like 150 g - this means my idea should be quite cheap and compete well with rechareable batteries) R134A refrigerant and could it be...
You're saying that you have to add water to lithium chloride to get it start absorbing more water from the air?
I thought that if you put dry lithium chloride in an enclosed space, it will absorb water from the air, bringing down the RH to 11.3%.
I'm intent on using seven points instead of four but they do say that four is the minimum to obtain a cubic equation. It will be interesting to see how the values I obtain if I use four values compare to using seven. Maybe using only four will still give an equation that enables accurate...
I want to do something more like https://www.allaboutcircuits.com/projects/how-to-check-and-calibrate-a-humidity-sensor/ where they do linear regression in a spreadsheet to get equations which correct the readings from their humidity sensors.
I know you can heat the lithium chloride to dry it...
Thanks for responding.
My goal is to find out the size of container I need for 30 g of several salts I wish to use for calibrating some humidity sensors with the assumption that I fail to close them tightly enough and they continue to absorb water from the air. I don't want them to be able to...
Is there some property that I can look up which would tell me how much water a hygroscopic salt can absorb (per unit mass of salt; for example anhydrous lithium chloride) before it's saturated and won't absorb any more?
You said:
but my glasses turn a blurry image into a sharp image for everything I look at (in concert with my own internal eye lenses). Thus I reason that there must be a way to calculate how an image should be displayed to a person with deformed eye lenses.
Negative. Without my glasses, my vision is blurry. With my glasses, my vision is not blurry. This use of the word blurry is layman and may not be correct usage in the field of physics. My glasses make a blurry image sharp.
I phrased it this way to make it easier to understand what I'm asking for. I want the antithesis of what my own defective eye lenses do to images I look at.
My glasses make the blurry image I see without my glasses appear sharp. Is it possible that I'm using the wrong terminology? Perhaps...
It's hard for me to tell whether I'm not understanding the answers or if my question is not being understood how I intended it. Would it make more sense if I asked could an image be printed with "anti-blur", blurred in such a way that I could read it clearly with my glasses off but most other...
Is it possible to print something with an ordinary laser printer that is blurred in such a way that it can be seen clearly by someone who ordinarily requires a strong prescription to correct their eyesight but would appear a blurred mess to someone with normal eyesight?
I'm pretty sure I was taught that microwaves operate at resonant frequency of water at school but that shouldn't be surprising since I had a biology teacher who didn't know whether yeast was alive and a couple of chemistry teachers with way worse understanding than mine (I learned from the...
