CalWave concludes 10-month test of its submerged wave energy generator

CalWave has been working on its xWave clean power technology for many years now, and has announced the successful conclusion of an extended open-ocean test off the coast of San Diego, in which the device demonstrated over 99% system uptime.Continue Rea… Continue reading CalWave concludes 10-month test of its submerged wave energy generator

A deeper dive into World Wide Wind’s colossal, contra-rotating turbines

We interviewed the core team at Norway’s World Wide Wind (WWW) to learn more about its floating, tilting, contra-rotating, double turbine design, which it says can unlock unprecedented scale, power and density to radically lower the cost of offshore wi… Continue reading A deeper dive into World Wide Wind’s colossal, contra-rotating turbines

Contra-rotating floating turbines promise unprecedented scale and power

Norway’s World Wide Wind has a radically different take on offshore wind power. These floating, vertical-axis wind turbines (VAWTs) feature two sets of blades, tuned to contra-rotate – and they promise more than double the output of today’s biggest tur… Continue reading Contra-rotating floating turbines promise unprecedented scale and power

Wave-riding generators promise the cheapest clean energy ever

Sea Wave Energy Ltd (SWEL) has been working for more than a decade on a floating wave energy device it calls the Waveline Magnet. With several prototypes tested on- and off-shore, the company claims it delivers “ultra low cost,” with high output.Contin… Continue reading Wave-riding generators promise the cheapest clean energy ever

Rechargeable aluminum: The cheap solution to seasonal energy storage?

Aluminum has an energy density more than 50 times higher than lithium ion, if you treat it as an energy storage medium in a redox cycle battery. Swiss scientists are developing the technology as a renewable energy stash for the European winter.Continue… Continue reading Rechargeable aluminum: The cheap solution to seasonal energy storage?

TAE ahead of schedule on billion-degree hydrogen-boron fusion

Some fusion projects aim to create hundred-million degree working temperatures in magnetically confined plasma. The CEO of TAE Technologies tells us his team’s aiming for 10 times that temperature, targeting cheaper, easier and safer boron fuel.Continu… Continue reading TAE ahead of schedule on billion-degree hydrogen-boron fusion

US nuclear regulator greenlights its first small modular reactor

The first generation-IV nuclear reactor design has been approved for certification by the US Nuclear Regulatory Commission (NRC). NuScale’s small modular reactor design promises safe, clean energy at radically reduced cost, land use and installation ti… Continue reading US nuclear regulator greenlights its first small modular reactor

Blowhole wave energy generator exceeds expectations in 12-month test

Wave Swell Energy’s remarkable UniWave 200 is a sea platform that uses an artificial blowhole formation to create air pressure changes that drive a turbine and feed energy back to shore. After a year of testing, the company reports excellent results.Co… Continue reading Blowhole wave energy generator exceeds expectations in 12-month test

First plasma propels Zap Energy’s plans for garage-sized fusion reactors

Nuclear fusion is an incredibly complex scientific problem that researchers are coming at from all sorts of angles, and Zap Energy is starting to make waves through one of the lesser-known approaches. The Seattle-based startup has achieved a major mile… Continue reading First plasma propels Zap Energy’s plans for garage-sized fusion reactors

Bizarre night-time solar cell generates power in a backwards process

In a world first, a team at the University of New South Wales (UNSW) has demonstrated measurable power generation from “the inverse of a conventional solar cell.” It could eventually produce around one tenth as much power as a solar panel – but at nigh… Continue reading Bizarre night-time solar cell generates power in a backwards process
