Tidal Lagoon Swansea Bay would be the world’s first man-made energy-generating lagoon

Energy trade association RenewableUK calls the UK "the undisputed global leader in marine energy." If plans for a tidal lagoon in Swansea Bay go ahead, that claim will be reinforced. Tidal Lagoon Swansea Bay would be the world’s first man-made energy-generating lagoon and could power over 155,000 homes.  Read More

The proposals are intended to produce new power sources, such as the fuel cell used in thi...

Once upon a time, energy systems for space missions were simple. You used batteries for very short missions, solar panels in the inner Solar System, nuclear power generators if you were beyond Mars or needed a lot of power, and fuel cells for manned spacecraft. However, as space exploration starts looking into lunar polar craters, comets, and the icy moons of Jupiter, new energy systems will be needed. To anticipate that need, NASA has made awards to four proposals to develop advanced energy storage technology for future manned and unmanned space missions..  Read More

Billions of cigarette butts are discarded around the world each year and, even when disposed of properly, pose a threat to the environment by leaching arsenic, lead and other nasty chemicals into land and waterways. New research shows these butts could be set for a new lease on life, with a team of Korean scientists demonstrating that used cigarette filters could actually double as a highly-effective energy storage material.  Read More

A team of researchers led by Newcastle University has produced an all-in-one Biofuel Micro Trigeneration (BMT) prototype system fueled entirely by unprocessed plant oils that provides combined cooling, heating, and electrical power. This first-generation system is designed for use in homes, with the potential for up-scaling for larger commercial and industrial applications.  Read More

By-products are common to most industries. Some are harmless, some dangerous and others useless. Others are simply under-utilized. VTT Technical Research Centre of Finland is using hydrogen generated as a by-product of the sodium chlorate production process in its pilot-scale power plant to produce electricity.  Read More

Researchers working at MIT’s Department of Mechanical Engineering claim to have produced a sponge-like substance that helps convert water to steam using sunlight one-hundredth as bright as that required by conventional steam-producing solar generators. A composite of graphite flakes layered on a bed of carbon foam, the new material is reported to convert as much as 85 percent of received solar energy into steam.  Read More

Illustration of the 'moth eye' solar cell (Illustration: Empa)

As nocturnal creatures, moths need to maximize how well they can see in the dark whilst remaining less visible to avoid predators. This ability to collect as much of the available light as possible and at the same time reflect as little as possible, has inspired Researchers at the Swiss Federal Laboratories for Materials Science and Technology (Empa) to design a new type of photoelectrochemical cell using relatively low cost materials.  Read More

The Yura concept proposes autonomous drink-flying robots

The annual Electrolux Design Lab competition for 2014 has reached stage three of the judging, and 35 semi-finalists remain. Many of the entries are innovative, some are quirky, and others are downright strange. But in the spirit of originality, they are all very individual, unique takes on various types of household devices that we may be using in the not-too-distant future. We have a look at ten of the entries that caught our eye to give you an idea of the competition so far.  Read More

The net-zero test home at the National Institute of Standards and Technology (NIST)

Braving a harsh winter with snow-covered solar panels, the Net-Zero Energy Residential Test Facility (NZERTF) in Washington DC has come up trumps in a year-long study of its energy harvesting capabilities. Located on campus at the National Institute of Standards and Technology (NIST), researchers used computer simulation to replicate the energy consumption of a family of four. At the end of its first 12 months, there was a large enough surplus to power an electric car for 1,440 miles (2,317 km).  Read More

A  large, distributed network of concentrated solar power plants in desert regions could r...

Researchers at the International Institute for Applied Systems Analysis (IIASA) have conducted a study to examine the potential for solar power to provide reliable electricity around the clock, every day of the year. The team found that a large, distributed network of concentrated solar power (CSP) plants in the Mediterranean basin or the Kalahari desert in southern Africa would be able to consistently run at 80 percent of maximum capacity or more throughout the year regardless of time of day, season, or weather conditions.  Read More
