Swarms of Floating Marine Turbines Could Harvest Power from the Gulf Stream

Advocates say harnessing the Gulf Stream could create one-third of Florida’s energy needs. Image: NASA While most marine power projects rely on turbines or other power-generating devices in relatively shallow water, researchers from Embry-Riddle Aeronautical University are attempting a new spin on the concept: Creating swarms of floating turbines, tethered to the sea floor or on movable undersea platforms, and deployed in the Gulf Stream hundreds of feet be… Read the full story on TreeHugger

The 20’s Plenty for Us Campaign (Video)

Roads in Residential Areas Should be Safe for All In residential areas, lowering the speed limit for cars not only reduces the number of accidents, injuries and deaths, but it also revitalises the neighborhood by encouraging more people to walk and bike. When people feel safe on the streets, they use greener forms of transportation more often. That’s the main argument of the 20’s Plenty for Us campaign in the UK, and looking at the results in areas where the 20 MPH speed limit was implemented, it looks like they a… Read the full story on TreeHugger

New Filter Could Make LCDs >400% More Efficient

Photo: Flickr, CC Negawatts Strike Back The immensely popular LCDs screens that are found everywhere in the modern home (television, computer, laptop, cellphones, etc) use less energy than CRTs, the previous technology, but they are still far from being optimally efficient. Only about 8% of the light emitted by a LCD’s backlight makes its way out, and the rest is wasted. But that might be about to change thanks to a new filter that could boost that efficiency by more than 400% and allow around 36% of the light to pass through. Read on for more details….

Homemade Preserves: To Buy or Not to Buy?

Images by B. Alter This is a familiar sight at farmers markets across the land: lovingly made preserves and pickled vegetables on sale. If you are too lazy and unmotivated, like some of us, what a great opportunity to pick up the fruits of some one else’s labour. Or not… Health inspectors in Vancouver are clamping down on this kind of home-grown and homemade produce. They are asking vendors to submit jams for lab tests and fill out forms listing ingredients. For some this is an invasion of their rights, for others it is a public health issue; a logical level of protection for the public…. Read the full story on TreeHugger
