New device turns sunlight into hydrogen with record efficiency

Posted by in categories: solar power, sustainability

As we strive towards a more sustainable future, it’s becoming increasingly important to find innovative ways to decarbonize industry and facilitate clean energy storage.

One promising approach is the manufacture of valuable products and fuels using available, low-cost feedstocks like water, carbon dioxide, nitrogen, and solar energy. By harnessing the power of these abundant resources, we can reduce our reliance on fossil fuels and move towards a cleaner, more sustainable energy future.

In a similar effort, Rice University engineers have developed a device that can turn sunlight into hydrogen with record-breaking efficiency – a significant step forward for clean energy. The device combines next-generation halide perovskite semiconductors with electrocatalysts in a single, durable, cost-effective, and scalable device.

Extracting a Clean Fuel From Water — A Groundbreaking Low-Cost Catalyst

Posted by in categories: climatology, sustainability

A plentiful supply of clean energy is lurking in plain sight. It’s the hydrogen that can be extracted from water (H2O) using renewable energy. Researchers are on the hunt for cost-effective strategies to generate clean hydrogen from water, with an aim to displace fossil fuels and battle climate change.

Hydrogen is a potent source of power for vehicles, emitting nothing more than water. It also plays a crucial role in several industrial processes, particularly in the production of steel and ammonia. The use of cleaner hydrogen in these industries would be extremely beneficial.

A multi-institutional team led by the U.S. Department of Energy’s (DOE) Argonne National Laboratory has developed a low-cost catalyst for a process that yields clean hydrogen from water. Other contributors include DOE’s Sandia National Laboratories and Lawrence Berkeley National Laboratory, as well as Giner Inc.

‘World’s largest sundial’ could generate nearly 400,000 kWh of electricity every year

Posted by in categories: solar power, sustainability

The project, called the Arch of Time, will stand 100 feet tall and generate enough solar power every year to offset 40 Texans’ home energy use.

Berlin architect Riccardo Mariano has designed an innovative new project for the city of Houston, Texas, that will generate nearly 400,000 kWh of electricity every year while acting as a public sundial.

The project, named the Arco del Tiempo (Arch of Time), will be a 100-foot-tall triumphal archway that will serve as the gateway to the city’s East End, part of the Second Ward district for the city. It will have a roof covered in photovoltaic modules to produce electricity as well.

Solar space butterfly could power lunar outposts around the clock

Posted by in categories: nuclear energy, solar power, space, sustainability

According to a study by Astrostrom for ESA, future Moon bases could be powered by a giant space butterfly called the Greater Earth Lunar Power Station (GEO-LPS) covered with solar panels made from lunar materials beaming microwaves to the surface.

One of the major design concerns in setting up a lunar base is finding a reliable means of powering it. Solar power might seem the obvious answer, but with lunar nights lasting 14 Earth days, it isn’t a practical option. However, though the most promising alternative is currently a small nuclear reactor, solar may not be out of the running.

The idea of solar power plants in space has been around for well over half a century. On Earth, solar panels are limited by night time, atmospheric haze, and bad weather, making them only capable of intermittent power generation with limited efficiency. On the other hand, in space, where there is no night and no atmosphere, solar power becomes very attractive.

US startup claims ‘commercial scale’ geothermal energy production after 30-day demo

Posted by in categories: computing, solar power, sustainability

The energy generation site will be connected to the grid and power Google’s data centers in Nevada.

Houston-based US startup Fervo Energy has claimed that it has achieved “commercial scale” geothermal energy production from its Project Red demonstration site in northern Nevada. The site recently completed a 30-day well test, a standard for geothermal energy installations, a company press release said.

Geothermal energy is one of the sources of renewable power being explored as the world moves away from fossil fuels. Unlike wind and solar power plants, geothermal energy can be sourced around the clock and on demand to cater to increased energy needs.

Using dragonfly wings to redesign a Boeing 777 to be lighter, stronger and more sustainable

Posted by in categories: sustainability, transportation

Throughout history, humans have observed and sought inspiration from many aspects of nature to improve flight efficiency, maneuverability, and stability. And since the days of Leonardo da Vinci, nature-inspired design, also known as biomimicry or bio-inspired design, has played and continues to play a significant role in the development of aviation.

Now, in a paper published in Advanced Science, Masoud Akbarzadeh of the Weitzman School of Design at the University of Pennsylvania and his former Ph.D. student Hao Zheng build upon the principles of biomimicry by drawing inspiration from the wing of a dragonfly to redesign that of a Boeing 777.

“Nature’s a great teacher in telling us how to optimize systems,” Akbarzadeh says. “And when you look at a dragonfly, you see wings that have evolved over millions of years into an incredibly lightweight, efficient, and strong structure.”

This underwater base could become the ISS of the ocean

Posted by in categories: climatology, space, sustainability

2020 underwater base.


Aquanaut Fabien Cousteau — grandson of famed ocean explorer Jacques-Yves Cousteau — has announced plans to build the world’s biggest underwater base for scientific research.

He calls the facility “Proteus” and envisions it being the ocean equivalent of the International Space Station — a place where scientists from across the globe can work together to solve the world’s biggest problems, from climate change to world hunger.
