Developed in 1993, the Q Drum is now used in ten countries throughout Africa. This tough, durable rotationally moulded Linear Low Density Polyethhylene (LLDPE) plastic roller enables 75 litres (19.8 gallons) of water to be easily transported -that’s 75 kg (165.3 lb) in weight – without causing the inevitable human damage associated with lifting and […]
The renowned Italian designer Alberto Meda, winner of two Compasso d’Oro prizes lighting products for Luceplan, turns his attention to the urgent and growing global challange of providing access to safe drinking water. A traditional DIY solution is to place old PET soda bottles on a roof to sterilize the water by UV-A sunlight and […]
More than a sixth of the world’s population does not have acces to safe drinking water, end each year more than 1.8 million people die from drinking dirty water. The LiveStraw® Personal, a compact portable water purifier weighing oly 140 g (5 oz) with its inbuilt filters, is literally, a lifesaver. Endorsed in the high-impact […]
Up to 17.4% of incident sunlight is converted into electrical power with these Sunways monocrystalline solar cells, a very efficient ratio compared with conventional solar cells. Various versions are manufactered, including those offering up to 30 % transparency. The transmitted light is white, yet there is arange of external colours for the cells, employing a […]
This was an early trial by BP Amoco using photovoltaic installations on canopies to generate the station’s electricity. Solar power has not become standard in all the petrol service stations, but BP has developed its solar capabilityby acquiring significant capacity in solar power manufacturing under its BP Alternative Energy devision. How the energy transition is […]
This water turbine is designed to be in afixed location where a moving budy of water passing by can generate up to 5 amps continuous charge for 12/24 volt systems, or can be used at sea on a moving vessel. In a fast-running stream, just 400 mm (15.7 in) deep, the UW 100 can generate […]
These wind energy converters are designed to work offshore exposed to high-speed, salt-laden winds, so all components are sealed to prevent ingress of water. Unique aspects of water. Unique aspects of the design include slow rotational movement to ensure that the unit can operate without maintanance for the first three years. Specifications for each turbine […]
These submarine windmills, driven by tidal or ocean currents, can capture large quantities of energy and are, arguably, less contentious interventions than their above ground cousins. Axial flow rotors of 15-20 m (49-65.6 ft) in diameter are mounted on twin lateral wings, each with a unique blade pitching system that allows 180ffl rotation flow, driving […]
The modular design of this solar collector, in four sizes of 14 to 21 tubes, allows for easy seperation of and almost 100% recycling of components. Materials have been kept to a minimum, giving a lightweight structure with high efficiency in low sunlight and at temperatures below freesing. Buro fur Produktgestaltung, Germany Paradigma, Germany Alumininium, […]
Traditional wood-burning stoves are stoked with atimber in a haphazard fashion, causing rapid, uncontrolled combustion with significant heat loss up the the chimney stack. GAAN’s range of wood-burning heaters encourage optimal combustion because wood is stacked vertically and burns from the top like a wick of a candle producing a fuel efficiency of 85%. As […]
