Highlights from the 2015 Geneva Motor Show

Alternative Energy

There's a lot of water constantly moving through the municipal pipelines of most major cities. While the water itself is already destined for various uses, why not harness its flow to produce hydroelectric power? Well, that's exactly what Lucid Energy's LucidPipe Power System does, and Portland, Oregon has just become the latest city to adopt it.  Read More

Researchers at ANU have replicated the primary capture of energy from sunlight (Photo: Shu...

Researchers at the Australian National University are one step closer to creating an artificial photosynthesis system after replicating one of its crucial steps. The development may lead to an abundant source of hydrogen, a cheap and clean fuel that could replace all petroleum products.  Read More

Equipped with an array of multi-junction photovoltaic chips, each of the IBM 'sunflowers' ...

Looking rather like a 10-meter (33 ft) tall sunflower, IBM's High Concentration PhotoVoltaic Thermal (HCPVT) system concentrates the sun’s radiation over 2,000 times on a single point and then transforms 80 percent of that into usable energy. Using a number of liquid-cooled microchannel receivers, each equipped with an array of multi-junction photovoltaic chips, each HCPVT can produce enough power, water, and cooling to supply several homes.  Read More

Biosynthetic propane can be produced by E. coli bacteria, and potentially photosynthetic b...

Propane is an appealing fuel, easily stored and already used worldwide, but it’s extracted from the finite supply of fossil fuels – or is it? Researchers at Imperial College London and the University of Turku have engineered E. coli bacteria that create engine-ready propane out of fatty acids, and in the future, maybe even sunlight.  Read More

The Stanford University system uses a glass layer patterned with micro-pyramids and cones ...

Photovoltaic cells are one of the more promising alternative energy sources. Mechanically they are very simple, with no moving parts, and are clean and emission-free. Unfortunately they are also inefficient. One of the reasons for this is that they overheat, a problem that a Stanford University team under electrical engineering professor Shanhui Fan is addressing with the development of a thin glass layer that makes solar cells self-cooling.  Read More

Researchers at Princeton University have converted CO2 into formic acid by using an electr...

Rising atmospheric CO2 levels can generally be tackled in three ways: developing alternative energy sources with lower emissions; carbon capture and storage (CCS); and capturing carbon and repurposing it. Researchers at Princeton University are claiming to have developed a technique that ticks two of these three boxes by using solar power to convert CO2 into formic acid.  Read More

The cell stacks that are the heart of a home fuel cell system being developed by Fraunhofe...

As the world shifts to alternative forms of energy, ways to make homes less dependent on the grid continue to gather steam. Fuel cells, which are more efficient and have lower emissions than internal combustion engines seem like a logical candidate for taking up the slack, so the Fraunhofer Institute for Ceramic Technologies and Systems (IKTS) in Dresden is partnering with the heater manufacturer Vaillant to develop a domestic fuel cell system that uses natural gas to produce both heating and electricity.  Read More

The Liam F1 Urban Wind Turbine is said to be considerably more efficient than most convent...

Although it's getting increasingly common to see solar panels on the roofs of homes, household wind turbines are still a fairly rare sight. If Rotterdam-based tech firm The Archimedes has its way, however, that will soon change. Today the company officially introduced its Liam F1 Urban Wind Turbine, which is said to have an energy yield that is "80 percent of the maximum that is theoretically feasible." That's quite the assertion, given that most conventional wind turbines average around 25 to 50 percent.  Read More

The Buoyant Air Turbine, from Altaeros Energies

Winds are stronger and steadier at higher altitudes, that’s why the Buoyant Air Turbine (BAT) from Altaeros is pushing to be the highest wind turbine in history. Already tested to 500 feet off the ground in 45 mph winds, this helium-filled shell with a wind turbine in the middle is soon shooting for a world record 1,000 ft float. Packing down into a shipping container for transport, the BAT is being proposed as a quickly deployable tethered power source for remote areas and emergency zones.  Read More

Festo has applied the same methodology used in its robotic SmartBird to harvest energy fro...

Back in 2011, Festo created a natural-flight mimicking bionic seagull with flapping wings dubbed SmartBird. The company is now looking to apply similar principles in order to convert wind power into electricity with its DualWingGenerator system.  Read More
