Not necessarily. It just requires excitation at a molecular level. You can get creative with your source. They have been playing around with low energy methods like LED or even just using the sun, geothermal, etc.
Yes, I’m aware of different way to distill, but if this were to work in a home/commercial setting, it needs to be accessible/affordable.
I’d personally love to get a home distiller, but I read they were very expensive to run :(
I was about to write back that we are not far off the advances to make these affordable and then did a google search and found that you can get a distilled unit on Amazon for $180 that is capable of making a gallon in 5 hours for about $.45 worth of electricity. That is far less than what it costs to buy distilled water at the store, which is around $1 a gallon. If you look at this from a break-even analysis, you technically start to reap the rewards of ownership after about 800 uses since the first 400 uses basically cost you $1.45 per gallon, then the next 400 costs you $.45 per gallon, but you are recouping that extra cost over the $1 retail price, so by the 800th use, you are getting water at less than half the price of the store.
A gallon is not much though, not for a family. If you have to double or triple that amount, the electricity costs will really add up. If you’re talking European electricity costs, you might as well drink expensive wine instead 😂
If cost was more in line with traditional filters, then it may be a more accessible option. But electricity costs are only going up.
Resistive heating is 100% efficient at turning electrical energy into heat
