Breakthrough solar cell captures carbon dioxide and sunlight, produces burnable fuel

Posted by in categories: solar power, sustainability

Researchers at the University of Illinois at Chicago have engineered a potentially game-changing solar cell that cheaply and efficiently converts atmospheric carbon dioxide directly into usable hydrocarbon fuel, using only sunlight for energy.

The finding is reported in the July 29 issue of Science and was funded by the National Science Foundation and the U.S. Department of Energy. A provisional patent application has been filed.

Unlike conventional , which convert sunlight into electricity that must be stored in heavy batteries, the new device essentially does the work of plants, converting into fuel, solving two crucial problems at once. A solar farm of such “artificial leaves” could remove significant amounts of carbon from the atmosphere and produce energy-dense fuel efficiently.

Scientists Synthesize Liquid Fuel from Solar Energy

Posted by in categories: solar power, sustainability

The nextgen of Solar and fuel energy.


Scientists have just discovered a way to directly convert solar energy into a synthetic fuel using carbon dioxide. Current solar technologies operate in either photovoltaic solar or thermal solar. Photovoltaic solar energy is generated through solar panels, which are typically seen on the roofs of houses and many solar plants. The other method of thermal solar is typically only used in large-scale energy plants, as it used mirrors to focus solar energy to heat a liquid which then powers turbines. Both methods, however, involve the conversion of solar energy into electricity. While electricity is useful, much energy is lost in the storing of electricity, something that the conversion process to liquid fuel overcomes.

Welcome to Lab 2.0 Where Computers Replace Experimental Science

Posted by in categories: chemistry, computing, mobile phones, physics, science, solar power, sustainability

We spend our lives surrounded by high-tech materials and chemicals that make our batteries, solar cells and mobile phones work. But developing new technologies requires time-consuming, expensive and even dangerous experiments.

Luckily we now have a secret weapon that allows us to save time, money and risk by avoiding some of these experiments: computers.

Quantum dot photosensitizers as a new paradigm for photochemical activation

Posted by in categories: chemistry, quantum physics, solar power, sustainability

Interesting work on solar energy and Q-dot photosensitizers.


Interfacial triplet-triplet energy transfer is used to significantly extend the exciton lifetime of cadmium selenide nanocrystals in an experimental demonstration of their molecular-like photochemistry.

Facebook’s solar-powered internet drone takes flight

Posted by in categories: drones, internet, solar power, sustainability

SAN FRANCISCO Facebook Inc (FB.O) said on Thursday it had completed a successful test flight of a solar-powered drone that it hopes will help it extend internet connectivity to every corner of the planet.

Aquila, Facebook’s lightweight, high-altitude aircraft, flew at a few thousand feet for 96 minutes in Yuma, Arizona, Chief Executive Mark Zuckerberg wrote in a post on his Facebook page. The company ultimately hopes to have a fleet of Aquilas that can fly for at least three months at a time at 60,000 feet (18,290 meters) and communicate with each other to deliver internet access.

Google parent Alphabet Inc (GOOGL.O) has also poured money into delivering internet access to under served areas through Project Loon, which aims to use a network of high-altitude balloons to made the internet available to remote parts of the world.

Facebook Test-Flies Drone to Bring Internet to Remote Areas

Posted by in categories: drones, internet, solar power, sustainability

US social networking giant Facebook announced on Thursday a successful test of its solar-powered Aquila drone, which will beam Internet to people in remote areas.

MOSCOW (Sputnik) — Facebook has been working on Aquila Project with leading experts in aerospace and communication technologies, from NASA’s jet propulsion lab to a small UK firm that created one of the world’s longest flying solar-powered drones.

Huge sail will power JAXA mission to Trojan asteroids and back

Posted by in categories: robotics/AI, solar power, space travel, sustainability

I wonder, if NASA and/or SpaceX goes to Mars in the 2030’s as planned, by the time the 2050’s roll around a manned attempt to Ceres or Jupiter trojans might be attempted or perhaps an unmanned vehicle made on Mars beats this sail.


Japan’s space agency has its sights on unexplored asteroids as far away as Jupiter, a project that at one level draws on centuries of sail science.

Facebook Heads For The Clouds With Its Internet-Streaming, Solar-Powered Aquila Drone

Posted by in categories: drones, internet, robotics/AI, solar power, sustainability

Tech now really moving into the clouds.


Although the world is increasingly connected through the internet, there are still four billion people or 60% of the world’s population who do not have such access. 1.6 billion of those people live in remote locations and do not have access to mobile broadband networks. Facebook Connectivity Lab just announced the first full-scale test flight of Aquila, a solar-powered airplane that can be used to bring affordable internet to isolated areas.

Aquila is a high-altitude, long-endurance, unmanned solar-powered airplane. It has a wingspan bigger than a Boeing 737 airplane but weighs hundreds of times less due to its carbon fiber frame. Many of the team members who contributed to the craft had previous experience at at NASA, Boeing, DARPA, Northrop Grumman, and the British Royal Air Force.

Facebook plans to beam fast Internet to remote areas using lasers

Posted by in categories: drones, internet, solar power, sustainability

So far the system can be used to receive signals carrying data at rates of up to 2.1 gigabits per second, though the team claims it could go faster if it were built to absorb infrared, rather than blue, light.

It’s worth pointing out that this isn’t the first piece of hardware to emerge from the Connectivity Lab. Famously, it’s been working on a solar-powered drone to deliver Internet access. That particular project is progressing slowly, though, so despite the fact that the team behind the new laser device plans to test it in a real-world setting, there’s likely still much development ahead before it’s used widely.

The social network is, however, busy pursuing plenty of other projects to take data to the sticks. Most notably, its Telecom Infra Project will use open-source cellular networks to achieve similar results. That way, you see, anyone will be able to sign up on Facebook.
