Aeromine says its unique “motionless” rooftop wind generators deliver up to 50% more energy than a solar array of the same price, while taking up just 10% of the roof space and operating more or less silently. In independent tests, they seem legit.

Distributed energy generation stands to play a growing part in the world’s energy markets. Most of this currently comes in the form of rooftop solar, but in certain areas, wind could definitely play a bigger part. Not every spot is appropriate for a bladed wind turbine, though, and in this regard, University of Houston spinoff Aeromine Technologies has designed a very different, very tidy form of rooftop wind energy capture that looks like it could be a real game-changer.

Thanks to a $19.2 million collaboration co-funded by the European Union.

Irish firm Ocean Energy has signed up to a collaboration project with 14 industry and university partners in the UK, Ireland, France, Germany, and Spain. The project will test its OE35 floating wave energy device at scale over the next four years.

Researchers have demonstrated a quantum sensor that can power itself using sunlight and an ambient magnetic field, an achievement that could help reduce the energy costs of this energy-hungry technology.

No longer the realm of science fiction, quantum sensors are today used in applications ranging from timekeeping and gravitational-wave detection to nanoscale magnetometry [1]. When making new quantum sensors, most researchers focus on creating devices that are as precise as possible, which typically requires using advanced—energy-hungry—technologies. This high energy consumption can be problematic for sensors designed for use in remote locations on Earth, in space, or in Internet-of-Things sensors that are not connected to mains electricity. To reduce the reliance of quantum sensors on external energy sources, Yunbin Zhu of the University of Science and Technology of China and colleagues now demonstrate a quantum sensor that directly exploits renewable energy sources to get the energy it needs to operate [2].

Data from the Parker Solar Probe confirms a long-suspected heat source for the Sun’s surprisingly hot corona, but there may be others.

The Sun’s surface temperature is around six thousand degrees kelvin, but the solar atmosphere—the corona and the solar wind—can reach a million degrees kelvin, a long-standing mystery in solar physics. Now, with data from the Parker Solar Probe, researchers have found evidence supporting a partial explanation for this mystery: magnetic waves driven by subsurface turbulence can impart energy to ions in these regions [1].

The exact mechanism of heating has been debated for decades, but the story appears to start with turbulent flow in the Sun’s convection zone, the outermost layer below the surface. In fluid dynamics, turbulence causes heating through a process known as turbulent energy cascade, where large eddies are converted into progressively smaller eddies. The energy in the smallest eddies is converted into heat through collisions between molecules.

The ocean covers most of our planet’s surface, accounts for the majority of our oxygen production, and provides a significant amount of resources by way of food, minerals, and energy.

Yet our oceans are shockingly underrepresented when it comes to environmental conventions on an international scale.

If you often find yourself off by one when counting your socks after doing the laundry, you might want to sit down for this.

Scientists in Japan have now counted the number of extra—or missing— charges down to a precision of just one electron in single platinum nanoparticles having diameters only one-tenth those of common viruses.

This new process for precisely studying differences in net charge on metal nanoparticles will aid in the further understanding and development of catalysts for breaking down greenhouse and other harmful gases into fuels and benign gases or for efficiently producing ammonia needed for fertilizers used in agriculture.

Located in northern Oregon, the renewable energy facility comprises 30 megawatts of massive lithium batteries that can store up to 120 megawatt-hours of power, generated by the 300-megawatt wind farms and 50-megawatt solar farm, powering around 100,000 homes.

The country plans to increase its installed renewable energy capacity to 25 GW by 2030.

Greece met its energy demands from only renewable sources of energy for a period of five hours on Friday, October 7, PV Tech.

Back in the U.S., the state of California has managed to reach this landmark milestone a couple of times this year. However, Greece’s achievement is remarkable as the region is also fighting off a self-imposed ban on using Russia-supplied gas, in the wake of the conflict in Ukraine.
