German firm introducing game-changing solar-wind-wave energy platform

A German power firm will launch demonstrations of a one-of-a-kind, triple-threat power generating platform off Iraklio, Greece, later this year.

SINN Power has been testing wave converter modules for five years. Buoys attached to steel frame components generate energy as waves push them up and down. The modular nature of the platform is unique in the industry.

“The has been a key element since we started developing maritime technologies that allow flexibility and a wide variety of applications,” according to SINN Power CEO Philipp Sinn. “The floating platform can supply to islands across the world … and contribute to the worldwide implementation of offshore wind farms.”

Novel Device Harnesses Shadows to Generate Electricity

Researchers have created a device called a ‘shadow-effect energy generator’ that makes use of the contrast in illumination between lit and shadowed areas to generate electricity. This novel concept opens up new approaches in harnessing indoor lighting conditions to power electronics.

Shadows are often associated with darkness and uncertainty. Now, researchers from the National University of Singapore (NUS) are giving shadows a positive spin by demonstrating a way to harness this common but often overlooked optical effect to generate electricity.

“Shadows are omnipresent, and we often take them for granted. In conventional photovoltaic or optoelectronic applications where a steady source of light is used to power devices, the presence of shadows is undesirable, since it degrades the performance of devices. In this work, we capitalised on the illumination contrast caused by shadows as an indirect source of power. The contrast in illumination induces a voltage difference between the shadowed and illuminated sections, resulting in an electric current. This novel concept of harvesting energy in the presence of shadows is unprecedented,” explained research team leader Assistant Professor Tan Swee Ching, who is from the NUS Department of Materials Science and Engineering.

The Future Of Fusion? Meet The Stellarator

Power and energy are essential parts of our everyday life. Every time you turn on a light, you’re using power. If you’re reading this online, you’re using energy. If you’re watching a video — you guessed it — you need energy. So that means that with so many people needing power and energy, we’re brought into a world that’s demanding more and more power. What’s more, getting this power is the hard part.

Global leader in harvesting energy and data from footfall

“Pavegen creates high engagement with citizens by converting their footsteps into energy, data and rewards.

As pedestrians walk across the Pavegen system, the weight from their footsteps compresses electromagnetic generators below, producing 2 to 4 watt seconds of off-grid electrical energy per step.”

Pavegen is a breakthrough smart city technology that creates high engagement with citizens by converting their footsteps into energy, data and rewards.

Laser cooling a nanomechanical oscillator close to its ground state

Researchers at the Swiss Federal Institute of Technology Lausanne (EPFL) and IBM Research Europe recently demonstrated the laser cooling of a nanomechanical oscillator down to its zero-point energy (i.e., the point at which it contains a minimum amount of energy). Their successful demonstration, featured in Physical Review Letters, could have important implications for the development quantum technologies.

Flodesign’s Jet Engine-Inspired Wind Turbine Could Revolutionize Wind Power Technology

We read about different innovations in clean technology almost on a daily basis. A small Massachusetts-based start-up, FloDesign Wind Turbine, has created a wind turbine design based on jet engine technology. This revolutionary wind turbine can generate much more electricity at half the cost than today’s traditional wind turbines. It has also won two clean-energy competitions for its amazing innovation.

A traditional wind turbine can extract just 50% of the available wind energy in the given area it occupies. However, the Wind Jet by FloDesign uses blades covered in shrouds to direct the air through the turbine blades. This results in increased flow of air. As the airflow through the blades increases, the higher the speed of the turbines and ultimately the more power that is generated. The energy generated by this new wind turbine matches that of a traditional turbine with blades that are half the size.

FloDesign boasts that its turbines are 3–4 times more efficient than traditional open-fan turbines and they can be placed much closer together than conventional wind turbines while aligning themselves with the wind like a kite on a string. Not only that, FloDesign wind turbines require much smaller blades which occupy less space, are much easier to manufacture, and easier to ship.
