Turbine Light concept

Ingenious, eco-friendly concepts are all around us, there’s no denying that. This one caught our eye because it’s pretty innovative, seemingly well thought out, and good looking to boot. The Turbine Light concept (which is going to be a part of the upcoming Greener Gadgets conference in New York City at the end of this month) harnesses the power of the wind from cars rushing past to light up the ever-darkening roadways. The turbines use the wind collected to generate energy for the lighting, and while the concept lacks a lot of firm details so far, but we’re sure to find out more about it soon — we’ll be sure to check them out at the conference on February 25th.

Cheap and super-efficient LED lights

Incandescent tungsten-filament light bulbs face a global switch-off as governments push for energy efficient fluorescent lamps to become the standard. But the light could soon go out on those lamps too, now that UK materials scientists have discovered a cheaper way to produce LED bulbs, which are three times as efficient as fluorescent lamps.

Although the ultimate dominance of LED lights has long been predicted, the expense of the super-efficient technology has made the timescale uncertain. The researchers now say LED bulbs based on their new process could be commercially available within five years.

Gallium nitride (GaN) LEDs have many advantages over compact fluorescent lamps (CFLs) and incandescent bulbs. They switch on instantly, with no gradual warm-up, and can burn for an average of 100,000 hours before they need replacing – 10 times as long as fluorescent lamps and some 130 times as long as an incandescent bulb. CFLs also contain small levels of mercury, which makes environmentally-friendly disposal of spent bulbs difficult.

SolarCap Light Emitting tile

The SolarCap system consists of modular, self-contained lighting devices that can be used for decorative or traffic flow purposes – powered only by solar energy. These unique devices incorporate the newest “EnergyCache” technology for energy storage, instead of the high maintenance rechargeable batteries that are currently used in solar deviced. Unlike batteries which must be changed every two-three years and can not tolerate environmental extremes, EnergyCaches enable SolarCap lighting to be used i any environmental without maintenance for more than 10 years with a wide operating temperature range of -25 – 60 degree C.

During daylight hours, the tiles use solar cells to capture energy from the sun that is than converted to electricity and storef using SolarCap’s EnergyCaches to automatically turn on soft light emiting diode (LED) lighting in the evening. Full charge takes about one hour under direct sunlight and up to eight hours in shady or indirect lighting conditions. The light will stay on for up to 12 hours with fully charged EnergyCaches.

Available in six colours, user can arrange SolarCap light emitting tiles in any imaginable shape or space to achieve a variety of drsired effects for residential or commercial applications in high-traffic or isolated areas. They can be easily installed just like a standard brick or tile on horizontal or vertical surfaces.
