Leeds 1025-77BK Elements – Water Powered Clock

Anita (EnviroGadget Writer) — Fri, 28 May 2010 09:00:01 +0000

The Leeds 1025-77BK Elements is a eco friendly water powered clock. The clock has a large, clear LCD screen for its display that is powered by water you place into the clock.

The Leeds 1025-77BK Elements turns water into electrical energy which it uses to power itself and its LCD display. The LCD screen measures 4.8 cm x 2.2 cm (1.875 in. x 0.875in.) which helps to ensure the information it displays is clear and easily seen. The clock can display both date and time on its display. As the clock is powered by water it can be placed wherever it is required, though some access to it is needed to allow you refill the clock with fresh water when it is required. After the clock has been filled with fresh water, it should provide enough electricity to operate itself for around a week and a half.

The clock measures 8.3 cm x 7 cm x 10.8 cm (3.25 in. x 2.75 in. x 4.25 in.). It comes with complete instructions for use and also includes a back up button battery, to help the clock function even when it has run out of power from the water. This ensures that it displays the time whenever you need it.

The Leeds 1025-77BK Elements Water Powered Clock is available for $20.10 plus shipping from Amazon.

MetalCell – Portable Battery Powered By Saltwater or Urine

Anita (EnviroGadget Writer) — Thu, 13 May 2010 09:00:03 +0000

The MetalCell is a portable battery ready for use anywhere. The battery allows you to generate energy for electronics like flashlights or even laptops from saltwater. Or, if there is no salt water about, it can use urine.

The MetalCell is said to have been conceived in South Korea for use by the military. The battery works by exploiting the chemical properties of magnesium. The magnesium plates react with the sodium in the salt water (or urine) which creates low voltage current. This electrochemical reaction can then be used to charge up any equipment, particularly equipment where there’s no immediate power source. Electronics are known for running out of power when it’s most inconvenient and when there is no chance to recharge them. For the military, where the problem can be life threatening, this battery is meant to be an emergency back up that can run from materials a soldier has to hand (be that saltwater or urine!).

The MetalCell could be extremely useful for home use in areas where a sudden cut of power is likely. The battery can be stored away safely for years, as the internal workings will not degrade with age. Due to it’s compact size, a number of batteries can be stored away in even small storage cupboards. As soon as you add saltwater or urine to the battery, it’s ready for use. In theory, the battery can run a laptop for around 4 hours. The battery will require refills of saltwater or urine to keep charge going, though eventually the magnesium plates would also require replacement.

H2O Water Powered Can Shaped Clock

Dan (EnviroGadget Writer) — Fri, 01 Jan 2010 10:00:13 +0000

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.

Vena Mini-Hydro System – Portable Turbine Generator

Dan (EnviroGadget Writer) — Fri, 29 May 2009 10:00:21 +0000

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 ECOlight – Water Powered Shower Light

Dan (EnviroGadget Writer) — Fri, 06 Mar 2009 10:00:29 +0000

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.

Timeless Garden – A Clock that Runs on Mud

Dan (EnviroGadget Writer) — Mon, 02 Mar 2009 10:00:32 +0000

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.

Liquid-Powered Digital Clock

Dan (EnviroGadget Writer) — Wed, 18 Feb 2009 10:00:03 +0000

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!

Lighting for your Swimming Pool powered by water

Dan (EnviroGadget Writer) — Wed, 17 Dec 2008 10:00:22 +0000

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?

Water Powered Calculator

Dan (EnviroGadget Writer) — Wed, 17 Sep 2008 09:00:44 +0000

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.
