UK-based firm launches 3D leaf-shaped solar charging stations

UK-based SolarBotanic Trees has launched its new photovoltaic (PV) 3D leaf-shaped nano-technology “solar tree” to harness solar energy for charging and energy storage, the company said in a press statement.

This first-generation energy tree aims at the electric vehicle charging market for residential and commercial car parks, where solar power can be captured and stored for charging points, the statement said.

It said the solar tree encompasses a sophisticated AI-driven energy storage and power management system, where trees can be linked and form part of a local grid, or feed into the main grid, adding that the first tree will become available in early 2023.

Protecting the orchard without reducing the available growing surface, with solar electricity being generated on the same land.

Sweet return: German farmer gets both solar power and apples

It’s picking season at Christian Nachtwey’s organic orchard in western Germany and laborers are loading their carts with ripe red Elstar apples, ready to be shipped to European supermarkets.

But Nachtwey’s farm is also reaping a second harvest: Many of the apple trees grow beneath solar panels that have been producing bountiful electricity during this year’s unusually sun-rich summer, while providing the fruit below with much-needed shade.

A team of scientists have designed an automatic pond aerator powered by pv panels - giving shrimp farmers access to sustainable energy

Researchers design a solar-powered shrimp pond aerator

The traditional aerators used in shrimp farming require a substantial power source – without it, shrimp production isn’t as effective or efficient. To help address this issue, the Community Empowerment Real Work Lecture (KKN PM) team from the Institut Teknologi Sepuluh Nopember (ITS) created a photovoltaic-based aerator to strengthen the farmers’ production efficiency.

PM I KKN team leader Putu Eka Widya Pratama SSi MSc RWTH says that aerators are essential to provide oxygen supplies to farmed shrimp as they develop. The lecturer, who also goes by Eka, explains that his team chose Gunung Anyar Tambak Village, Surabaya, to implement the innovation because it is developing its own shrimp farming industry and is expected to become a digital village by developing renewable energy.

Germany’s Liontron can prepare 300 cups of coffee a day from the PV modules and storage tech on its bicycles for beverage vendors.

Solar-powered bikes prepare cups of coffee in Germany

Espresso, cappuccino, flat whites – you need a lot of electricity to prepare coffee. And it is sometimes not easy for the operators of mobile coffee shops to obtain energy in public places.

Germany battery specialist Liontron has developed a solution for this: a mobile coffee-shop bike that uses built-in lithium-iron phosphate batteries to provide enough electricity to prepare coffee all day long. Two PV modules with outputs of 200 W each charge the batteries.

University of Cambridge Researchers have designed lightweight, flexible devices that use solar technology to convert light into fuel.

Could this tiny floating leaf decarbonise some of the world’s biggest polluters?

,

Cargo ships could one day be powered by ‘artificial leaves’ floating out at sea.

University of Cambridge Researchers have designed lightweight, flexible devices that use solar technology to convert light into fuel.

At just 1mm thick, the ultra-thin ‘leaves’ can float on water – and could eventually go “almost anywhere,” according to study lead Professor Erwin Reisner.

Sono Motors' Solar Bus Kit allows subsystems like the HVAC to be partially powered by renewable energy thereby saving fuel, CO2, and costs

Production design of Solar Bus Kit fleet revealed

Sono Motors recently held its first “Celebrate the Sun” Community event. During which, the Munich-based OEM celebrated the debut of its Solar Bus Kit, a scalable B2B retrofit solution that reduces fuel consumption and inner-city greenhouse gas emissions, thereby contributing to climate protection, the company noted.

The Solar Bus Kit is optimized for the most common 12-meter public transport bus types on the European market, including Mercedes-Benz Citaro and MAN Lion City. Sono Motors will offer a complete and efficient retrofit solution for bus fleet operators who have a compelling need to reduce diesel consumption and CO2 emissions to meet their sustainability goals.

The 48-level building features a “solar skin” facade, from which it will generate energy for 20 percent of its base electrical requirements.

‘Solar skinned’ Melbourne tower approved

,

A $1 billion development at 435 Bourke Street has been approved by the Victoria’s planning department.

Designed by Bates Smart, the 48-level building will feature a “solar skin” facade, from which it will generate energy for 20 percent of its base electrical requirements.

To be made from vertical glass photovoltaic panels, the solar skin is designed to capture sunlight and convert the energy into electricity. The innovative skin can also let natural light in, providing the same thermal and insulation capacities as architectural glass.

Using concentrated solar energy, researchers at ETH were able to produce kerosene from water vapor and carbon dioxide directly from air.

Solar-to-jet-fuel system readies for takeoff

As climate change edges from crisis to emergency, the aviation sector looks set to miss its 2050 goal of net-zero emissions. In the five years preceding the pandemic, the top four U.S. airlines—American, Delta, Southwest, and United—saw a 15 percent increase in the use of jet fuel. Despite continual improvements in engine efficiencies, that number is projected to keep rising.

A glimmer of hope, however, comes from solar fuels. For the first time, scientists and engineers at the Swiss Federal Institute of Technology (ETH) in Zurich have reported a successful demonstration of an integrated fuel-production plant for solar kerosene. Using concentrated solar energy, they were able to produce kerosene from water vapor and carbon dioxide directly from air. Fuel thus produced is a drop-in alternative to fossil-derived fuels and can be used with existing storage and distribution infrastructures, and engines.

RCF Connects is retrofitting homes to make a "virtual power plat" - and fighting gentrification at the same time.

The plan to turn blighted houses into a new source of green power for the grid

Standing outside the sagging house on 2nd Street in North Richmond, California, it was hard to imagine it as the future site of a pioneering clean energy project. The building’s rotting white siding seemed to sink into the dirt yard with no real foundation. Chunks of it were crumbling to the ground. As we walked around to the back, Jim Becker, my tour guide, pointed to a plastic pipe sticking out of the wall.

“Here, the sewage was just flushing out onto the dirt,” he said. “It was just shooting all the poop into the garden.”

But Becker was excited. He was showing me this house as a sort of “before” picture. Soon, workers will take the building down to its studs and reconstruct the walls and roof. Then it will get a full menu of clean energy offerings: energy-efficient lighting, an electric vehicle charger, an electric stove, electric heat pumps for heating and air conditioning, an internet-connected “smart thermostat.” Solar panels will line the roof, and a backup battery will allow future residents to keep the lights on and the refrigerator running during a power outage.

The satellite’s 11-meter solar wing from its folded stowed configuration allows it to fit in the rocket fairing.

See the enormous solar panels of this Earth-monitoring satellite

The European Space Agency (ESA) and Japanese Space Agency (JAXA) are preparing to launch a new Earth-monitoring satellite called EarthCARE which will study clouds and aerosols to see how they interact with the atmosphere and contribute to its temperature. As part of testing the satellite’s hardware before launch, the craft’s solar panel wing was recently unfurled for the first time.

EarthCARE has a large set of instruments for taking measurements, including an atmospheric lidar, a Doppler cloud radar, a multispectral imager, and a broadband radiometer. This range of instruments is necessary to understand the complex relationship between clouds, aerosols, radiation, and climate change. But this many instruments require a lot of power, hence why the satellite is also equipped with a huge five-panel solar wing.
