A group of researchers at Uppsala University in Sweden have discovered that a particular type of algae — with a bad reputation for causing damaging algal blooms in oceans throughout the world — produces a substance that can be used to make inexpensive, non-toxic, simple-to-build, flexible, thin and durable batteries that, after optimization, are expected to perform on par with today’s most advanced lithium-ion batteries.
The key to the discovery lies in the way in which the algae, Cladophora, produce a unique type of cellulose with a very large surface area (approximately 80 square meters of surface area per gram of material).
By coating this algal cellulose material with a thin layer of a well-known, conductive polymer, called polypyrrole (PPy), the team has “succeeded in producing a battery that weighs almost nothing and that has set new charge-time and capacity records for polymer-cellulose-based [non-metallic] batteries,” according to Gustav Nyström, a doctoral student in nanotechnology and one of the main researchers.
Officials in Sweden have introduced a shoot to kill and cull campaign in an effort to reduce the amount of vehicle accidents and damage to forests due to the growing number of moose in the country. 42 people have been killed and almost 2,000 people have been injured in road collisions involving moose over the past five years.
World Water Week (August 16-22) brought some interesting information and important research findings to the world. We got a peek at the true water usage of developed countries, we identified some critical concerns for Indians and all of us who rely in Indian products, we learned more about water usage for beer, we saw the installation of the first commercial-scale hydrokinetic power plant in the US, and more. The following is a wrap-up of some key topics from the World Water Week Conference in Sweden.
The Electric Transportation Engineering Corporation (eTec), a subsidiary of ECOtality, Inc. and Nissan North America win a $99.8M grant from the Department of Energy to support the largest deployment of electrical vehicles (EVs) and charging infrastructure in U.S. history.
The project will use Nissan’s LEAF, an early stage zero-emission EV to study and develop the logistics and necessary scale behind the implementation of a national charging infrastructure, that will in turn, support large-scale EV deployment. Initial stages of the project include the deployment of 5,000 EVs and EV charging stations in Arizona, California, Oregon, Tennessee, and Washington. Don Karner, President of eTec, sums up the industry e-coup:
By studying lessons learned from electric vehicle operations and the infrastructure supporting these first 5,000 vehicles, the Project enables the streamlined deployment of the next 5,000,000 electric vehicles…Nissan and over 40 government and industry partners, will enable this Project to successfully pave the way for electric transportation nationwide.
Our race to find alternative fuels is critical not only because gasoline-powered vehicles emit lots of CO2–it’s also important because we’re running out of the sticky stuff. But what if the Earth could produce fossil fuels without the fossils?
Nowali Cable Knit Moccasin are adorable, cozy, and actually stay on little one’s feet! If you have a toddler, you’ve probably experienced what usually happens with slippers designed for little ones…they always slip off! Not with Nowali, which are made in Sweden and are great on any floor surface.
Diane Reznik, Nowali’s Sales Manager and co-designer, describes these great slipper socks:
Our feature product is our famous Swedish moccasin. This item is a unique combination of a sock and a shoe: knit sock upper with a leather sole and color coordinated foxing. The moccasins are still stitched together by hand in the traditional Swedish way.
Swedish scientists have discovered that vast numbers of wild birds in the Baltic Sea area are dying of a strange paralytic disease caused by advanced thiamine (vitamin B1) deficiency in eggs, young, and adults.
In a new research paper the team, from Stockholm University, Sweden, report that levels of Thiamine, vital for the proper functioning of the nerves, were found to be deficient in the eggs, livers and brains of several local bird species, contributing to significant declines in many bird populations over the last few decades.
Hearteningly, it seems that paralysed individuals can be successfully remedied by thiamine treatment
The European Union (EU) and MTV are working together to get young people involved in the climate debate. The major entities started their “Play to Stop – Europe for Climate” campaign this month. Working with international music artists and other international celebrities, this is a major campaign to mobilize the youth around the topic of climate change, and especially for the Copenhagen Climate Conference in December.
The campaign targets 11 EU countries — Bulgaria, the Czech Republic, Denmark, France, Germany, Hungary, Italy, Poland, Romania, Sweden, and the United Kingdom. The campaign will involve celebrities from the various participating countries.
In a meeting with environment and energy ministers from other European countries yesterday, Sweden’s Minister of Environment, Andreas Carlgren, said that global economic problems should in no way slow movement to address climate change. Other leading European ministers agreed.
Economic problems today are in many ways a result of environmental missteps in the past. If we want a healthy economy in the future, we have to take the environment into account more than we have. The Swedish Minister of the Environment agrees and says that there should be no hesitation to combat climate change due to the current economic situation.
Swedish supercar manufacturer Koenigsegg acquired a controlling interest in Saab so that it could get its hands on the company’s electric car production facilities.
The claim, made on Swedish language website realtid, cites unnamed sources in saying that the move is likely to bring the cutting-edge solar-powered Quant EV concept car (pictured) a step closer to production reality.
Sources also suggest that low volume production of the ZEV Quant (video) is expected to begin in a couple of years. The car was designed by Swedish outfit NLV Solar AG, a world-leader in photovoltaics and electrical-power technology.
