Due to the fairly low light output of LEDs, it’s easy to see that LEDs offer great potential for micro-illumination, i.e. enough lighting for a very small area. LEDs offer very directional lighting, and this dictates what they can be used for without using special diffusers. However, Jason Bruges found a novel use for a...
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.
Sometimes these eco-friendly gadgets do end up being a little odd, however, this is a green gadget focussed firmly on the kids. This is a hand-powered torch in the shape of a penguin.
Now when I’ve been lucky enough to have an open fire in the first place, I’ve typically just rolled old newspaper into balls. However, this slightly pretentious (yet elegant) creates ready to use logs out of old newspapers ready to start your fire.
It’s refreshing to find a hand-powered green gadget that’s actually useful, particularly with the . With just 1 minute of cranking, you get 80 seconds of shaving time. If you charge up the shaver via the mains, it would take 8 hours and give you around 60 minutes of shaving. However, if you’re in the...
Chrysler has announced a new green transportation vehicle that is eco friendly, being emission free, using electric power rather than petroleum derivatives. The car features iPod and iPhone integration, where the latter doubles as a mobile phone hands free feature too. The Peapod is small, yet available in 2-seater, 4-seater and 6-seater models.
Hand-powered torches have been around for ages. Essentially you repeatedly squeeze a lever that converts the linear motion into a rotational motion that drives a dynamo. The dynamo then charges an internal battery that allows the low-powered light (often LED-based) to light up for a few minutes or hours. However, the Mini Dynamo Massager Torch,...
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...
M2E Power are working on a range of alternative energy generation devices that exploit the Faraday principle. Energy is generated by a moving magnet within an coil, which could be then used for commercial and military applications. The M2E Power team are working on a highly efficient variation that offers between 300% and 700% more...
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...
