Salt – Sustainable Alternative Lighting

I think that by using the "powered by water and salt" phrase they are trying to present the product in layman's terms. For most of the people it's sufficent description to understand the product and using the "galvanic" term wouldn't help to understand it better.

However it would be nice if they had a "how does it work?" subpage with scientific explanation - for the credibility.

With the term "powered by water and salt", it makes it seem like the battery can be "recharged" by replacing the salt. This is not the case, when the battery loses power, the battery is "recharged" by replacing the copper and zinc electrodes (or whatever metals they are using).

So a less scammy description would be to say that is is powered by copper and zinc. This is more correct both technically and to a layman.

I disagree, it causes laymen to completely misunderstand the product. The product is not "energy from water and salt". The product is a fixed quantity of chemical energy sold in the form of the metal anodes/cathodes. This is no different than selling non-rechargeable batteries.

They are not presenting the product in layperson's terms. They are misrepresenting it as badly as saying, "A car that runs on rubber! Just add tires!" and then making money by selling buyers gasoline.

Wonderful analogy! I liked it, anyway.
