Familiar with Rayton Solar?
This was originally from a December 2014 blog entry published by Inhabitat, but I felt this was worth reposting:
Striking another blow to the oil and gas industries, an American solar company has developed technology that can produce super-efficient solar power that’s cheaper than fossil fuels. Rayton Solar’s new solar panel manufacturing technology uses 50 to 100 times less silicon than other technologies, cutting out large amounts of the most costly component of solar panels. The company says its patent-pending process uses just four microns worth of silicon, leaving no waste – while boosting the efficiency of their panels to 24 percent. According to the company that’s 25 percent greater than the industry standard efficiency, which currently tops out at about 15 percent.
Rayton claims their patent-pending solar PV modules can be manufactured in the United States at a cost of 60 percent less than the industry average, which is based on prices from places like China where the majority of solar panels are made.
The Los Angeles-based company currently has an Indiegogo campaign underway that’s seeking funding to help put the final touches on the technology so it can get UL certification and then be launched for sale to the general public. Launched on Dec. 16, 2014, the campaign is working toward a $250,000 goal.
The development of solar PV technologies like this is one of the main factors behind an marked increase in global renewable energy production, which went up by 8.5 percent in 2013.
Urine into electricity?
Yes, and much more. Maker Faire Africa is a wonderful website that offers example after example of ingenuity in action across Africa.
One recent spotlight article focused on some amazing creations from Lagos. One that was particularly fascinating was the work of four young women who fabricated technology to convert urine into fuel for an electrical generator.
North America, Western Europe, Asia — they receive near constant coverage in media for innovation and invention. Tech reporting from Africa is far less emphasized and Maker Faire Africa gives regional coverage that is long overdue on the global stage.
Spend a few minutes with Maker Faire Africa and experience “ingenuity in action.”

Current computing is based on binary logic — zeroes and ones — also called Boolean computing, but a new type of computing architecture stores information in the frequencies and phases of periodic signals and could work more like the human brain using a fraction of the energy necessary for today’s computers, according to a team of engineers.
Vanadium dioxide is called a “wacky oxide” because it transitions from a conducting metal to an insulating semiconductor and vice versa with the addition of a small amount of heat or electrical current. A device created by electrical engineers at Penn State uses a thin film of vanadium oxide on a titanium dioxide substrate to create an oscillating switch.
Using a standard electrical engineering trick, Nikhil Shukla, graduate student in electrical engineering, added a series resistor to the oxide device to stabilize oscillations over billions of cycles. When Shukla added a second similar oscillating system, he discovered that, over time, the two devices began to oscillate in unison. This coupled system could provide the basis for non-Boolean computing. Shukla worked with Suman Datta, professor of electrical engineering, and co-advisor Roman Engel-Herbert, assistant professor of materials science and engineering, Penn State. They reported their results today (May 14) in Scientific Reports.
“It’s called a small-world network,” explained Shukla. “You see it in lots of biological systems, such as certain species of fireflies. The males will flash randomly, but then for some unknown reason the flashes synchronize over time.”
The brain is also a small-world network of closely clustered nodes that evolved for more efficient information processing.
“Biological synchronization is everywhere,” added Datta. “We wanted to use it for a different kind of computing called associative processing, which is an analog rather than digital way to compute.”
An array of oscillators can store patterns — for instance, the color of someone’s hair, their height and skin texture. If a second area of oscillators has the same pattern, they will begin to synchronize, and the degree of match can be read out.
“They are doing this sort of thing already digitally, but it consumes tons of energy and lots of transistors,” Datta said.
Datta is collaborating with Vijay Narayanan, professor of computer science and engineering, Penn State, in exploring the use of these coupled oscillations to solve visual recognition problems more efficiently than existing embedded vision processors.
Shukla and Datta called on the expertise of Cornell University materials scientist Darrell Schlom to make the vanadium dioxide thin film, which has extremely high quality similar to single crystal silicon. Arijit Raychowdhury, computer engineer, and Abhinav Parihar graduate student, both of Georgia Tech, mathematically simulated the nonlinear dynamics of coupled phase transitions in the vanadium dioxide devices. Parihar created a short video simulation of the transitions, which occur at a rate close to a million times per second, to show the way the oscillations synchronize. Venkatraman Gopalan, professor of materials science and engineering, Penn State, used the Advanced Photon Source at Argonne National Laboratory to visually characterize the structural changes occurring in the oxide thin film in the midst of the oscillations.
Datta believes it will take seven to 10 years to scale up from their current network of two-three coupled oscillators to the 100 million or so closely packed oscillators required to make a neuromorphic computer chip. One of the benefits of the novel device is that it will use only about one percent of the energy of digital computing, allowing for new ways to design computers. Much work remains to determine if vanadium dioxide can be integrated into current silicon wafer technology.
“It’s a fundamental building block for a different computing paradigm that is analog rather than digital,” said Shukla.
