The H2O Water Powered Can Clock uses state of the art water technology to power a large hi contrast display (LCD) clock. This clock will run continuously for a long time without needing any human intervention.

By using positive and negative electrodes (in a similar way to the potato clocks of old, yet more attractive) the H2O Water Powered Can Clocks patented technology creates an electrochemical reaction with water, thus producing the electrical energy for powering the LCD clock display. The Can clock is the size and shape of a conventional can of drink, roughly 11cm x 5.8cm (4.3in. x 2.3in.), its coloured transparent body allowing you to see the electrodes within.

The water will need replacing due to evaporation. The evaporation though should be at a slow rate as the water is well encased, meaning it will only require a water top up every 6 to 12 months.

The battery for the H2O Water Powered Can Clock does have a minimum continuous life of 2 years, though by simply allowing the device to fully dry out when no longer required you will elongate its years of usage, as it will be ready to go again as soon as the can shaped clock is once again full of water.

The Vena Mini-Hydro System is a portable generator kit that charges a power-pack from the flow of water. The turbine part of the generator is stuck into the river bed, and the flow of the river drives the turbine. A thick wire then leads back into the power pack to charge it up.

Designed by Daniel Hull, the Vena Mini-Hydro System is designed to be an eco-friendly generator pack for remote power requirements. Of course, you’ll need to be near a river to make use of it.

Interestingly, there seems to be no protection against debris or perhaps any wildlife that might be floating in the river. I’d expect some kind of protective mesh over the blade to protect both wildlife and the turbine.

SYLVANIA’s ECOlight LED Water Powered Shower Light is a fun eco gadget that will give you light in the shower, powered only by the flow of water through the gadget. Using a tiny water turbine, the flow of water produces enough energy to illuminate you when giving yourself a scrub.

The LED light itself is adjustable, so you can point it in any direction you want. As an additional safety feature, the outside edges of the ECOlight will change to red when the temperature goes above 41 degrees Celsius (105.8 degrees Fahrenheit), or go blue when the temperature goes below 25.5 degrees Celsius (78 degrees Fahrenheit).

Sure it doesn’t serve any particularly practical purpose, but it’s fun, easy to install and doesn’t need any batteries.

We’ve almost seen it all, a water-powered clock, a lemon-powered clock, now we have a mud-powered clock! Designed by Francesco Castiglione Morelli and Tommaso Ceschi, the Timeless Garden uses the chemical reaction between metal and mud to generate enough electricity to power a clock!

You can plant what you like in the clock, and grass has been chosen for this design. Not only do you remove the need for electricity, but the oxygen-generating benefits of a plant also does its bit for the environment. Going one step further, the clock itself is made from recycled plastic.

As far as eco-friendly clocks go, this has got to be the most appealing I’ve ever seen. It would be even more useful to have a larger plant pot, as well as a clock that uses the MSF signal to automatically set itself to the right time.

The Mini Hydro Clock is a small clock (about 2.5cm by 5cm) which simply displays the time. No alarm function, no date or calendar information. Just the time.

However, what is interesting is that you can power it with any fluid you like, including water, juice, milk and beer. I imagine that the smell from the milk when it goes off will be pretty nasty though! Considering you can use almost any water-based solution to power the clock without batteries…. you could use urine too!

If you’re lucky enough to have your own swimming pool, then you’ll have some pool lighting. These clever EcoLights, designed by Lysandre Follet are powered by a built-in turbine that powers the bright LEDs. This means you don’t need to worry about installing electricity in and around your pool.

The Eco-Lights need to be connected to the pre-exisiting flow from the filter pump, which use the flow of water to drive the mini turbine. Therefore if your filter pump is switched off, the lights won’t be on. An interesting idea though. Perhaps another idea would be to combine solar power and tidal power (i.e. water lapping) to power the lights?

The Nano-Tech Water Drop Puzzle is simply a puzzle that cleverly exploits surface tension in water to allow you to use individual water drops instead of marbles or metal bearings in a toy.

Although the unit is using plastic for the game, it does mean the game is suitable for young children, as there are no harmful small parts to worry about. It’s a funky idea, eco-friendly, and it looks fun!

It seems as if the water-powered gadgets are becoming a bit of a trend. The water-powered green gadgets typically seem to be very low powered and use a small LCD screen. This new water powered calculator has a small re-fillable cartridge that will power the calculator for up to 3 months with just a few drops of water!

It’s a standard calculator, so it lacks the features of the powerful graphical or technical calculators. Since the battery is powered from water, it’s an eco-friendly technology, great for the environment, and doesn’t need any expensive alkaline or lithium batteries.

I recently reviewed a water powered desktop calculator, and now there’s a Water Powered Clock. Using a combination of water and salt, the clock electrodes generate a current sufficient to power the clock for quite a while. This eco gadget is bright and colourful, and it’s bound to attract attention if you’ve got it on your office desk!

This neat calculator uses a water-based battery to generate enough current so that you can do your sums with the environment in mind! Just top this eco gadget up with some water and it will run for up to 3 months until the water has evaporated. Then you just need to top it up again.

Strictly speaking, the water is not the power source, it’s an electrolytic conductor which contains an ample supply of electrons to flow between the anode and cathode of the special “water battery”. This flow of electronics is essentially a current, enough to power the calculator. This is similar in principle to powering a clock from a potato or lemon.
