Microbial Fuel Cell Could Propel Navy Ships for Years, Feeding on Sea Microorganisms
The microbial fuel cell is meant to use naturally occurring fuels and oxidants in the sea to power ships, replacing batteries and fossil fuels.
IBM and Stanford Discover Chemical Recycling of PETs at Low Temperatures
Usually, plastic bottles, (aka PETs) are recycled by mechanical technologies, and they get several other uses afterwards: carpets, sweaters, etc. They don't ever return to their original water bottle use.It is possible to chemically recycle PETs, but the method has been so far very expensive and the industry doesn't want that option.
New Kind of Magnetic Solder Eliminates Toxic Lead
A group of scientists at the Yale University have created a new type of magnetic, lead-free solder that could be used to manufacture electronics more efficiently and cheaply.
Data Center Under Uspenski Cathedral Recycles Heat for 500 Helsinki Homes
The former WW2 bomb shelter in Helsinki became the center of attention lately, since a data center located there is going to be contributing to the town's heating system, powered by Finnish company Helsingin Energia, starting next month.
New Discovery: Generating Electricity With Ground Bacteria Shewanella
Bio-chemist David Richardson of the University of East Anglia in the United Kingdom said that Shewanella is the ideal candidate for environmental-cleanup tasks as it lives in the underground: "Understanding their biochemistry could help to develop strategies to stimulate their activities [at the cleanup sites]."
Korean Scientists Find Quick and Easy Way to Produce Bio-Plastics
Petroleum stands at the base of every plastic we usually find on today's market. Polymers are everywhere, and if petroleum resources are about to go scarce with time, it's a good idea to replace it with other renewable and biodegradable material that we could use just as well as we use petroleum today.
Indian Students Develop Bio-Cell to Clean Sewage Water and Generate Electricity
A group of students at the Indian Institute of Technology in Kharagpur have developed a bio cell(battery) that can be used to treat sewage water and generate electric energy, being a perfect solution to combat the water and energy crisis.
Cereplast's Algae-Based Bioplastics Reduce Petroleum Use by 50%
Cereplast has already developed some new technologies before, being able to make plastic from renewable materials such as corn starch, tapioca, wheat and potatoes.
Cheap Nanotube Sensors to Detect Toxins in Water
A research team at Stanford has developed a new inexpensive sensor chip made with carbon nanotubes, being capable to detect rapid traces of TNT and poison in rivers, reservoirs.
Rainwater Harvesting System Capable of Capturing over 20,000 Gallons of Water
Jerry Block, a retired anesthesiologist, located in Monte Sereno, California, has developed in his backyard a rainwater harvesting system, capable of holding and collecting up to 20,000 gallons of rainwater each year.
