Microbial fuel cells turn urine into a constant flow of electrical power

Human urine has been turned into all sorts of things over the centuries. Alchemists distilled phosphorous from it, it was once used for the production of gunpowder, tanners employed it in great vats to tan hides, and it has served as the basis of a myriad chemical substances, including the first types of plastics. Now yet another use for this ubiquitous liquid has been created. Researchers working at the University of the West of England (UWE Bristol) have built a urinal that converts urine directly into electricity.  Read More

Researchers in Spain have developed new, high-performance acoustic insulation material fro...

Homes may one day benefit from improved acoustic insulation with an orange flavor after researchers in Spain managed to turn waste material from orange trees into high-performance acoustic insulation. The new material is more environmentally friendly to produce and an improvement in terms of acoustic insulation compared to conventional laminated gypsum boards.  Read More

A process developed at CU Boulder not only cleans up waste water but also generates power ...

A treatment process developed by engineers at the University of Colorado Boulder promises a simpler and more economical way to clean up the wastewater produced by oil and gas operations that is heavily salinated and full of organic contaminants. The technique, which involves the use of a microbe-powered battery, also produces rather than consumes energy.  Read More

A new high-efficiency biogas plant developed at the Fraunhofer Institute in Germany could ...

Researchers at the Fraunhofer Institute have developed a "biobattery" in the form of a highly efficient biogas plant that can turn raw materials like straw, scrap wood and sludge into a variety of useful energy sources including electricity, purified gas and engine oil. The new plant design, currently being put to the test in a prototype plant in Germany, is said to be highly modular and economically viable even at the small scale.  Read More

Under construction in Sweden, EcoDataCenter will have a positive impact on the world aroun...

Information and communications technology consumes a full 10 percent of the world’s electricity, meaning that whenever a new data center is designed, its efficiency is of paramount concern. A new project, known as EcoDataCenter, will be the world’s first-climate positive data center, utilizing various techniques and technologies to ensure a positive impact on the wider world.  Read More

Tesla home battery, which is currently produced for SolarCity's home energy storage system...

The same lithium-ion battery technology that powers Tesla’s electric vehicles will be used to develop a battery for the home, according to a statement by CEO Elon Musk during a recent conference call with analysts. The batteries would be used by homes and businesses to store excess energy generated from solar panels during the day, and drawn from at night when panels sit idle.  Read More

Atherny in Ireland will host one of Apple's new data centers

We're creating more data than ever before – YouTube receives 300 hours' worth of video uploads every minute – and all of those 1s and 0s have to be stored somewhere. With this in mind Apple's €1.7 billion (around US$1.9 billion) European data centers, which will be powered entirely from renewable energy sources, show a commitment to the planet's future.  Read More

The energy-harvesting tree collects energy from light, temperature differences, and vibrat...

In January, the VTT Technical Centre of Finland unveiled its decorative, mass-producible organic photovoltaic (OPV) leaves designed to capture energy from interior lighting to power small devices and sensors. Now, the company has followed the logical path and come up with an energy-harvesting tree that generates electricity from a variety of sources.  Read More

A previous LucidPipe installation, with one of the turbines visible inside the pipe (Photo...

There's a lot of water constantly moving through the municipal pipelines of most major cities. While the water itself is already destined for various uses, why not harness its flow to produce hydroelectric power? Well, that's exactly what Lucid Energy's LucidPipe Power System does, and Portland, Oregon has just become the latest city to adopt it.  Read More

30-cm (11.8-in)-deep moisture projection based on NASA's high carbon emission scenario in ...

A new NASA study is predicting the occurrence of severe "megadroughts" across the United States in the second half of this century, that are set to be more extreme and prolonged than any droughts that have taken place in the region for the past 1,000 years. According to the study, one of the key driving forces behind the devastating droughts will be the prolific creation of human-produced greenhouse gasses.  Read More
