A new design devised by a team of Penn State graduate researchers opens up a future of sustainable wastewater treatment.
The same kinds of bacteria used in wastewater treatment plants can also generate small amounts of electricity. But these two abilities have rarely been combined so cleverly.
In a study published last week, Penn State University researchers outlined a system called the microbial reverse electrolysis cell (MRC) that both cleans water and creates electricity.
Today it’s too expensive for practical applications in the field, but it opens up the possibility not only for more efficient wastewater cleanup, but also for hybrid water-treatment and power plants that can do both.

(Phys.org) -- Researchers in Spain have succeeded in building a photodetector that is a billion times more sensitive than other such detectors based on graphene and could herald the use of graphene based light sensors and solar cells.
"To build their photodector, the team first created a graphene substrate using the standard graphite sticky tape procedure, to which they affixed tiny gold electrodes using nanoscale lithography.
Following that, they applied lead sulphide crystals to their device via a spray bottle. Because the crystals weren’t filtered, they came in a variety of sizes, which accounted for virtually all of the different wavelengths of light."

The “Internal Combustion Boundary Layer Turbine Engine (BLTE),” a derivation of the Tesla Turbine Engine is now being presented as a premier “Internal Combustion Prime Mover.”
The BLTE is capable of producing phenomenal output power for its size due to the fact that so little energy is being used internally to run the engine itself.
This invention can be used in place of any reciprocating engine application (automotive, aerospace, marine, power tools, and as a replacement to many battery applications...

Nearly 80 percent of disease in developing countries is linked to bad water and sanitation. Now a scientist at Michigan Technological University has developed a simple, cheap way to make water safe to drink, even if it’s muddy.
"It’s easy enough to purify clear water. The solar water disinfection method, or SODIS, calls for leaving a transparent plastic bottle of clear water out in the sun for six hours."
"It’s a different story if the water is murky... to purify your water, you first have to get the clay to settle out, a process called flocculation. Working with student Brittney Dawney of Queen’s University in Ontario, Pearce discovered that one of the most abundant minerals on Earth does this job very well: sodium chloride, or simple table salt."

Stacked layers of graphene could make effective shields...
"Despite being just one atom thick, graphene is a strong absorber of electromagnetic radiation over a wide range of wavelengths – particularly in the far infrared and terahertz parts of the spectrum. This is extraordinary because conventional materials normally need to be thousands of atoms thick to be as effective."
"Phaedon Avouris and colleagues at IBM's TJ Watson Research Center in New York have created a film comprising alternating layers of graphene and an insulator. The team has shown that a film containing just five layers of each material can shield electromagnetic radiation in the terahertz and microwave ranges by up to 97.5%, while remaining transparent to visible light."
"Graphene could be used as a transparent terahertz and microwave shielding material and so help prevent external electromagnetic interference in high-accuracy electronic equipment," he said. "Such a shield could even help protect people from radiation at these wavelengths, which are hazardous to human health, according to the World Health Organization."

One German physicist, Harald Haas, has come up with a solution he calls "data through illumination" - taking the fiber out of fiber optics by sending data through an LED lightbulb that varies in intensity faster than the human eye can follow. It's the same idea behind infrared remote controls, but far more powerful.
"You can imagine all kinds of uses for this technology, from public internet access through street lamps to auto-piloted cars that communicate through their headlights."
"And more data coming through the visible spectrum could help alleviate concerns that the electromagnetic waves that come with WiFi could adversely affect your health. Talk about the bright side."
(My comment:) Since the transmission is of several contemporaneous data streams using different wavelengths or colors of light, there should not be any low frequency data 'packets', nor should there be the potential of heating of tissues which is inherent in microwave technology.

"The Captive Column is an invention that could revolutionize the construction industry. It can be used to make just about anything: Airplanes, Bridges -- you name it."
(My comment:)
I have come across this before and want to link it here to keep track.
The captive column is an invention that allows the fabrication of ultra-light yet incredibly strong structural members, to be used in anything from bridges to airplanes, from cars to whatever you might think of.
The technology is open source, since the patent expired in the 1980s. The inventor, who obviously never was able to "sell" his idea to someone who would put it into production, got someone to make a website for him.

TED Talks Taylor Wilson believes nuclear fusion is a solution to our future energy needs, and that kids can change the world. And he knows something about both of those: When he was 14, he built a working fusion reactor in his parents' garage.

"BlackLight's continuously operating, power-producing system converts ubiquitous H2O (water) vapor directly into electricity, oxygen, and a new, more stable form of Hydrogen called Hydrino, which releases 200 times more energy than directly burning hydrogen," said Dr. Randell Mills, Chairman, CEO and President of BlackLight Power, Inc., and inventor of the process.
Hydrogen is not naturally available and has to be produced using energy. But, H2O vapor is ubiquitous and free, obtainable even from ambient air. Dr. Mills says that BlackLight has achieved critical milestones in scaling its new technology with typical electrical gain of more than ten times that which initiates the process, operating over long duration at the 10 Watt (W) scale.
A 100 W unit is planned for completion by the end of 2012, and a 1.5 kilowatt (kW) pilot unit that can serve the residential power market, as an initial target commercial application, is expected to become available by 2013.

(Phys.org) -- French company Eole Water has announced that they have developed and are now in the process of selling wind turbines that have been modified to produce fresh drinking water.
"The turbines work by combining two current types of technology; traditional generation of electricity using wind as the driving force, and compressors commonly used by dehumidifiers and refrigerators."
"The water that is produced drips down to the base of the turbine tower where it is filtered and delivered for use."
"The new turbines do have one major drawback and that is the price..."

"Learn how to assay, cupel, melt and smelt your precious metals in a microwave oven at home. Any600 to 900 watt kitchen microwave will do to illustrate melting and casting metals in a microwave. The gold process takes three to four iterations. The melting is impressive and one can see that the temperatures to get the gold processing going is easily achievable."
"We will demonstrate each process and reveal what type of processing units are required to perform each type of metal processing. Attendees will observe melting of gold dust into buttons, as well as up grading placer gold and old jewelry to 95 % plus. In addition, you will learn how to assay and cupel your gold and silver ores sample in a low cost kitchen microwave."

Cyclone Power Technologies, a Pompano Beach, Florida company, focuses on solving our dependence on fossil fuels with its heat regenerative external combustion engines.
"This engine works when steam enters the top of each of the six radially arranged cylinders (20) and pushs the pistons (54) downward in sequence."
"The rotating action of the pistons connected through the spyder bearing (60) turns the crank shaft (24) in an orbiting motion around the central longitudinal axis of the crankshaft (24)."
"The engine does not use motor oil as water is both the working fluid and the lubricant."
"The engine can run on any source of heat, including waste heat from industrial sources."
