Hydrogen fuel out of sun and sewage!

Hydrogen fuel could be a good alternative to conventional ones as it is zero-emission and could be considered as environmentally friendly. But there comes the question of is it reliable enough? According to Wikipedia, “Hydrogen production always requires more energy than can be retrieved from the gas as a fuel later on”. It’s quite confusing, right? So why bother you with this information?

A research team at the University of California has developed a novel device that uses only sunlight and wastewater to produce hydrogen gas and it could be considered to provide both sustainable energy source and improved wastewater treatment. The hybrid device combines a microbial fuel cell (MFC) and a solar photoelectrochemical cell (PEC), which separated generate electricity, but working together provide a self-driven process driving electrolysis of water which splits it to hydrogen and oxygen. In the MFC component, bacteria degrade organic matter in the wastewater, generating electricity, which is then delivered to the PEC component to assist the solar –powered electrolysis of water.  Sounds promising! More information you can find on Science Daily.

The first climate refugee!

A man from the Pacific nation of Kiribati is trying to convince New Zealand’s immigration authorities that he’s a refugee suffering not from persecution, but from climate change, reported The Independent. He and his wife left the atoll where they were living, six years ago as rising sea level brought overcrowding, crops killing, homes flooding and unsafe drinking water. As immigration authorities rejected twice his arguments for staying in New Zealand, on 16 October his lawyer will argue the case before New Zealand’s High Court.

Waste plastic bags turning into carbon nanotubes!

Carbon is found almost everywhere, including plastic – one of the world’s favorite material and also one of the world’s most abundant wastes. Searching for better materials and fighting plastic waste can be done “in harmony”, but making the material out of the waste is far better. Carbon nanotubes are well known for their strength and lightness as well as their numerous applications. At the University of Adelaide a group of researchers have developed a process that turns the harmful plastic wastes into the high-tech and wanted nanomaterial. They used pieces of grocery plastic bags, which they vaporized in a furnace to produce carbon layers that line the pores of nanoporous alumina membranes to make tiny cylinders or nanotubes. Initially using ethanol, they have come up with the idea that they could use any carbon source and this way minimize environmental pollution while producing high-added value products. According to the scientists the process is also catalyst and solvent free, which means no poisonous compounds are generated.

Stone paper?

What do you think of when hear paper made of stone? A heavy production process or waste, dust, new product, innovation? According to Wikipedia this manufacturing has started in the late 1990s – regarding the technology progress this is not a new product, not at all. FiberStone® is one of numerous companies, producing this intriguing kind of paper. And they claim stone paper has great advantages over traditional one. The paper’s components are 80% of calcium carbonate, found abundantly in nature, and 20% HDPE – high density polyethylene, and it is tree-free. What makes this product sustainable? FiberStone® explain that the calcium carbonate in their paper is coming from limestone as a waste material from already existing quarries. We know where the HDPE comes from, but the production process of the stone paper is clean, does not use toxic chemical or water and does not need bleaching like the conventional one. Another advantage of this material is that it is recyclable and could be applied in other products. It sounds great! What do you think?

STEPS – the first climate friendly snowboard and ski film!

Remember Ride Greener – the Swiss association promoting eco-friendly winter sports? Now, they along with Coupdoeil Film have produced STEPS, which they claim to be the first climate friendly snowboard and ski film. The film shows the effects of Climate Change in parallel with the allure of winter sports and brings up the question of whether or not winter sports today can be done in harmony with nature. According to its creators, the documentary tells the story of people deeply connected to the mountain, looking for alternative and sustainable ways to follow their passion, but also unveils the real paradox existing in doing winter sports in harmony with nature. For now, we can enjoy the trailer released, but it is enough to catch our attention.
