The Waste2tricity process

It’s common knowledge that the majority of electricity generation and waste disposal methods currently in widespread use are not very environmentally friendly. New British venture Waste2tricity aims to kill two environmentally damaging birds with one stone by taking carbon based waste, either municipal solid waste (MSW) or waste from business and industry, and converting it into clean electricity, thereby reducing the amount of rubbish going to landfill and potentially making a significant contribution to the UK electricity supply.  Read More

Heliotex solar panel wash system

When we think of solar panels we think of saving energy, burning less fossil fuel and reducing greenhouse gases that contribute to global warming. Few of us however realize that by not cleaning the panels regularly they could lose up to 30% of their power, off setting these benefits and costing us money. To address this problem, Heliotex a Southern Californian based supplier of solar panel cleaning systems and solar panel anti-theft devices has announced the release of the first patent pending automatic cleaning systems for business and home solar panels.  Read More

Cyclone Power Technologies - Waste Heat Engine

Technology capable of generating electricity by extracting energy from heat that is otherwise just wasted is a fairly new branch of renewable technology. A typical co-generation plant uses waste heat from a gas or steam turbine for hot water or space heating. This Waste Heat Engine (WHE) developed by Cyclone Power Technologies operates at temperatures as low as 225F (107 C). The engine can generate up to 10kw from heat sources such as industrial ovens or furnaces, concentrating solar thermal collectors, engine exhaust and biomass combustion.  Read More

The GeoBulb LED light bulb

Not so long ago choosing a light bulb wasn’t too difficult. Just grab one with the desired wattage in either pearl or clear with the correct fitting for your socket. The need for energy efficient lighting means that it's no longer that simple, and given the amount of ongoing research in the area, the range of light bulb options on the supermarket shelves is set to explode. Technologies competing to replace conventional incandescent bulbs include OLED, Compact Fluorescent Light (CFL) bulbs, and of course LED bulbs. LED bulbs offer improved energy efficiency, produce brilliant light and offer long life and this new LED bulb offering, called the GeoBulb II, puts out more light than a standard 60-watt bulb and uses just 7.5 watts.  Read More

Green Ocean Energy's Wave Treader

Bringing together the benefits of two eco-friendly forms of power generation, Scottish company Green Ocean Energy has developed a wave power machine that attaches to an offshore wind turbine. The system, known as the Wave Treader, comprises two 20 m (66ft) long floats molded from GRP (Glass Reinforced Plastic) at ocean level attached to a wind turbine tower by 50 m (165 ft) long pivoting beams. As the floats move up and down in response to constant wave action, the arms move hydraulic cylinders attached to the beams by levers, which in turn spins a hydraulic motor connected directly to an electric generator.  Read More

Surface Power Solar Vacuum system

Irish company Surface Power has launched what it claims is the world’s most efficient solar hot water panel. A report from Silicon Republic states that certification by testing house TUV Rhineland has shown that the innovative product is up to 131% more efficient in morning and evening time and 76% more efficient at midday than other panels.  Read More

Australian Scientists developing spray on solar panels

Researchers in Australia have started a three-year project to develop a spray-on coating for solar panels and more efficient cells that are less costly than today's PV. Australian National University (ANU) is working with new Australian solar company Spark Solar and Finnish materials company Braggone Oy on the method, which could be commercially available by 2011.  Read More

Protect your iPhone with recycled Columbian truck tires

Better Energy Systems have added new smart phone protective cases - including one for the iPhone - to their eco-friendly range. Tread cases are manufactured from re-engineered Colombian truck tires and the resulting recycled material is heat resistant, can withstand temperatures of up to 110 degrees C (230 degrees F), is not weakened by UV light and can even survive acid being poured on it.  Read More

RITI printer design concept by Jeon Hwan Ju

The paperless office is a great notion, but in reality there are still many scenarios where the printer needs to be switched on and fed with environmentally unfriendly consumables - paper and ink. Recycling and re-using paper for print jobs has become well entrenched, but the expensive and often frustrating process of replenishing the ink remains an issue for many of us. Which brings us to one of the cleverest recycling ideas to emerge from this year's Greener Gadgets competition - the RITI printer. This design concept by Jeon Hwan Ju takes your coffee or tea dregs, plus a little elbow grease, and turns them into an eco-friendly alternative to conventional ink.  Read More

The 'holy grail' of lighting

Cambridge University researchers have developed cheap, light-emitting diode (LED) bulbs that produce brilliant light but use very little electricity. They will cost just GBP2 (USD2.80) and last up to 60 years. The gallium nitride based bulbs are 12 times more efficient than conventional tungsten incandescent bulbs and three times more efficient than compact fluorescent low-energy bulbs. As well as lasting 100,000 hours, ten times as long as today's eco-bulbs, the LED bulbs do not contain mercury, so disposal is less damaging to the environment, they do not flicker and fully illuminate instantly, unlike the current generation of eco-bulbs.  Read More
