Well, a very slick website and apparently lots of awards, but very few facts.
It seems to be pretty disingenuous - it says it is "Sustainable and cost effective ecologically designed lamp powered by "tap water" and "table
salt!", which if they've built one they will know isn't true. This device is a crude battery with an LED stuck to it. The battery is fuelled by
whatever metal the anode is made from, which is likely to be zinc, magnesium or aluminium - they don't say.
Once this metal is used up, the battery is useless and will need replacing - it is not a rechargeable battery. They don't say how much it will be to
replace the anode (or how much any of this costs), or where a remote islander will get a new anode from. Although they might have access to
saltwater, I reckon they won't have their own metal smelting plants.... I also suspect charging your phone on this will run it down very quickly -
again there are no real facts.
If you want something sustainable then a car battery with PV cells attached to it would be a better bet. For a small lamp why not use one of the many
cheap and effective wind up lamps already on the market?
