I know that having portable, modern day lighting is nothing new, but when you think about it, an old school item can still be rethought and shaped to resemble, or usher in the future. Case in point, the humble lantern. We have seen its evolution in the past, where from being powered by gas or oil, here we are with a LED powered version. Enter the $39.99 Mini Hozuki LED Candle Lantern, which is actually a tiny, highly portable backpacking lantern that is also durable, shining light whenever and wherever you need it.

With multiple lighting modes that will include a couple of candle modes, the Mini Hozuki LED Candle Lantern boasts of a magnetic tail that enables it to wrap around poles and loops, ensuring that your precious Mini Hozuki remains in place right where you need it, letting you concentrate on other more important matters – such as fending off a group of goblins. Still, sometimes I believe that the traditional torch would work much better, since some creatures can only be scared by fire and heat. Powered by a trio of AAA batteries, this portable LED lantern can last up to 40 hours in High Mode.

Who would have thought that a clever mixture of salt and water could result powering a lantern of the future,it thanks to the efforts of the folks over at Green House of Japan. This LED lantern of theirs will survive on electricity that is generated through water and salt. Also known by its tongue-twisting model number “GH-LED10WBW,” the LED lantern does not need any dry cell or rechargeable battery to run, and will burst into life the moment water and salt are put inside.

Each charge of water is said to deliver up to 8 hours of electricity, now how about that? The clever and careful mixture? We are looking at 350ml of saline water that holds 16 grams of salt, mixed together using a dedicated water bag. The saline water works as an electrolyte with a magnesium (Mg) rod (negative electrode) and a carbon rod (positive electrode) within the lantern to get it lighted up at a luminosity of 55 lumens. No idea on pricing, but this special LED lantern should the Japanese market sometime from the middle of this month onwards.

Japanese company Green House Co Ltd has quite an eclectic product portfolio, what with its women-only camcorder and peripherals like a PCI Express interface card with USB 3.0 support. Its latest device falls under another category entirely: the rivetingly named GH-LED10WBW is an LED lantern that runs on just water and salt; no batteries required. The light source provides eight hours of electricity per dose of saline water, and the lantern comes with a dedicated water bag for mixing the solution. The salt / water combo acts as an electrolyte with the magnesium (negative electrode) and carbon (positive electrode) rods inside the lantern. Users can get about 120 hours of power with the Mg rod before they’ll need to buy a replacement (the rod is sold separately to begin with). More than just supplying a battery-free source of light, though, the lantern can function as a charger, thanks to a USB port built into the casing. Pricing has yet to be announced, but the GH-LED10WBW will be available by mid-September.
