Unique hydro energy system harnesses slow water currents
Image Gallery (3 images)
Hydro-power systems are by far the most widely used form of renewable energy on the planet, but despite their eco-friendly appeal the implementation of large scale facilities - particularly where dam building is involved - has some serious environmental and economic drawbacks. One solution to this impasse that is growing in support is to use leaner, less destructive systems to better harness current flow and provide energy at a local level. This is the thinking behind VIVACE, a machine developed at the University of Michigan which applies the same principles fish use to swim efficiently in order to generate power from currents much slower than those required to drive designs based on turbines and water mills.

StatoilHydro to build 2.3MW offshore floating wind turbine
Image Gallery (2 images)
The world desperately needs viable sources of renewable energy and wind power is among the most promising solutions, but one downside is that turbines can be considered a blight on otherwise picturesque landscapes. The solution seems obvious enough - move the towers far out to sea where not only are they out of sight, but where the wind is at its strongest and most consistent. We first encountered this idea back in 2006 when we examined the efforts of MIT researchers to integrate a turbine with a floating platform similar to those used by offshore oil rigs. Now news that Norwegian oil and gas company StatoilHydro plans to invest around US$80 million to build a full scale offshore floating wind turbine. Read More

May 15, 2008 Advancing a viable market for photovoltaic solar energy involves a balancing act between creating efficient solar cells and at the same time reducing the cost of the manufacturing process. Solar efficiency has been demonstrated to levels as high as 22% (a record set by SANYO last year), and although HelioVolt Corporation's latest announcements concern technology that is only delivering 12.2% conversion, the company has made great strides on the other side of the equation. Its proprietary FASST reactive transfer printing process has produced solar cells in a record setting six minutes, according to HelioVolt that's 10 to 100 times faster than current production of thin-film photovoltaics and could lead to manufacturing costs of less than $1 per watt.

Bourne Energy's RiverStar: a fresh approach to hydropower
Image Gallery (5 images)
March 5, 2008 Hydroelectric dams produce little-to-no emissions and draw energy from a renewable resource, but they are still plagued with the inherent problems of all large-scale power plants: they’re costly to build and maintain, land intensive, and have negative environmental consequences. That’s why Bourne Energy believes the future of hydropower, and the solution to global energy demand, is in small generators that harness power from river currents. The company's RiverStar power modules collect kinetic energy by passing the water through low RPM turbines that don’t harm aquaculture. The units can be cheaply mass-produced, and require no construction on river bottoms, allowing them to be installed quickly and inexpensively even in areas inhospitable to development. Read More

February 13, 2008, According to the EPA, if consumers bought more recycled environmentally-friendly products, not only would they help to make the recycling process a success, they would also put pressure on manufacturers to produce high-quality recycled products. Toy manufacturers are often among the worst offenders when it comes to excess packaging and plastic toys but now a UK company has developed a range of children’s toys which are not only made of recycled material but are also themselves recyclable.
