I just looked at the website http://www.hydralight.net/technology/ , very nice, but how do you shut off the light (battery) after you have tipped it into water.


Once the battery is activated it will run its course. Let's say I need light for one hour and then two months later I need light for another two hours? New light (battery), right?


This is not a game killer, but it limits its use.

No, I don't think that is strictly true. In the versions I know about, the consumable anode is only consumed when current is being drawn from the cell, IIRC. So you can turn it off electrically and let it dry out and then it can be re-activated when needed, as long as there is some anode material left.
 
The drawback I saw was the buildup of the reaction product, which must be cleaned out and disposed of periodically. This reaction product is generally harmless but I hesitate to think about millions of users all down at the beach cleaning out/activating their Hydralights at the same time.

a marvelous idea.its a current-to-voltage transformer in there somewhere(l.e.d.s need very little i and lots v).at neutral ph the anode wil alkaline over time and increase resistance.at vinegar ph the thing can go for a while

Hi TK
please email me your address again I will send you one. The new one is maintenance free, the waste is contained in the cell. We are also doing a fully bio degradable one made from bmboo.


I sent Stefan one some time agao

@makdansie, TK, Stefan:

May be markdansie can answer my question, or Stefan and TK will have some experience with the water activated battery.

I understand that the water activated battery can be stored for many years as long as it is not activated (stays dry).

But what happens once it is dipped in salt water? A slightly acidic solution will be created in the battery which allows a corrosion process causing electrons to flow between anode and cathode.

Electrons only flow if the light is turned on. So one could let the battery dry out without using it up. And later one ads water again to create the acidic solution again.

I imagine that letting the battery dry out causes chemical reactions which are not reversible and therefore constitutes some "loss". The "loss" will probably be a shorter electricity production than in the case of a one time cycle.

Case 1: adding water and turning the light on and letting it shine till the battery is used up will give you light for instance 100 hours.

Case 2: adding water, turning the light on for some time, then letting the battery dry out, adding water again, and letting the light shine till the battery is used up, will give you in total light for a shorter time than in case 1.

Now the question: how much are the "losses" if one lets the battery dry out and adds water again months or years later?

This is not a criticism, I just want to know how the battery reacts to multiple dry outs.

Greetings, Conrad

chemicaly speaking,there'l b a major buildup of scum over time.resistance increases

Many thanks to Mark Dansie by bringing this finally to the market.
I guess their new Website URL had not been posted here,
so here it is:
http://www.hydra-light.com/

I think this is also an metal-air battery so the graphite plates have to be able to breath air, that is Oxygen...
as Oxygen is needed to be converted at the graphite electrode to go into ions to decompose and magnesium alloy
and to produce current...
So if other persons try to replicate this, make sure your graphite plates are not always under
water or fully inside the electrolyte bath, cause otherwise they can not "breath" air and thus they only can convert the air, that was stored in the graphite matrix, before they were put into the saltwater....
I also always wondered myself earlier, why my saltwater cells became more and more weaker, when I realized
that the graphite electrodes can not breath any air anymore, when they are almpst completely inside the saltwater...
So the best thing would be to put these graphite plates on one side as the wall of the container and with the other side in contact with the electrolyte,
so on the one side they can fully "breath" the air and at the other side are fully immersed into the saltwater electrolyte...
It seems they have exactly done this as you can see here:
http://www.hydra-light.com/#!technology/c24vq

Especially seen in this great picture:
https://static.wixstatic.com/media/4b4cbd_bc14c62da3a5423d9f92d4e3f7e83c26.png
The graphite plate seems to breat air from the other side not beeing in the saltwarer electrolyte...
Well Done Mark Dansie and Team !

Regards, Stefan
