Substitution

Because of its light weight Graphene is the ideal substitute for copper for aerospace defense against emerging weapons technologies such as electromagnetic pulse as well as lightning strike protection for the aerospace market.

"Tinned copper clad aluminum wire

Tinned copper coated aluminium wire
Standard: ASTM B566-93
Diameter: 0.10-3.0
CCA wire is mainly used as conductor under high-frequency in coaxial cable taking the place of pure copper wire
CCA wire has soft state (A kind) and hard state (H kind)
CCA wire has 10% and 15% two kinds according to volumetric scale of copper layer "

"The curtain will eventually come down for silicon in today's manufacturing methods once engineers can no longer further shrink transistors and the copper wires that connect them. Processor fabrication using new technologies such as imprint lithography, graphene, and quantum computing will continue to yield faster and smaller chips. "

"Generator


Brushless, 3-phases neodymium magnet generator

Brushless Generator: NO motor brushes in our generator and a maintenance-free design with strong neodymium magnets. Old style generators have motor brushes that require regular maintenance. Brushes are high failure items and need replacements regularly."

"Controlled Power Technologies' breakthrough in the development of a second generation stop-start system, which outperforms existing designs of modified starter motors and alternators in almost every respect, is being demonstrated to engineers and automotive experts this week at Europe's largest conference for vehicle electronics, which is held every two years at Baden-Baden in Germany.

The production-ready SpeedStart system is an advanced solution that is more powerful, more efficient and more usable than first generation stop-start systems. It's the first design to integrate all the power and control electronics into a single electric motor assembly and by maximising the number of stop-start events the system aims to significantly reduce fuel consumption and CO2 emissions beyond the NEDC (New European Drive Cycle) measured minimum."

""In the future, a tremendous amount of energy savings could be realized in industry by switching from Si inverters to SiC inverters because the power loss of the inverters is estimated to be reduced by more than 50 percent,""

"At some point the industry is going to have to transition," Jeff Ravencraft, the USB-IF's president and chairman, said in an interview, because copper wires such as those in the current USB 2 and new USB 3 standards have limits on how fast they can transmit signals. "I think the next transition is going to be to optics."

According to Postley, 50 copper-based cables on the set of a 3D shoot could be replaced by a single optical cable with Light Peak technology, which Intel also claims can simultaneously transport multiple existing I/O protocols.

SiC challenges a $2.6B silicon device market

This $2.6B Total Accessible Market is part of the overall $12B Si-based power discretes business (2008). Today the largest applications in potential revenue remain Power Supply PFC, UPS and Motor AC drives. Tomorrow, EV/HEV and inverters for PV installations will take the lead exhibiting higher CAGR (>15%/year). However, cost issues slow-down SiC penetration and we only forecast ~4% of the overall Silicon-based power discretes market to be displaced by SiC in 2019. Low-Voltage applications (< 1.2kV) are representing over 99% of today SiC device sales but we anticipate a huge increase of Medium-Voltage applications (1.2kV-1.7kV) in the next 2 years. High-Voltage apps will slowly appear from 2013-2014 along with technology improvement and cost reduction.

Washington, June 5 : In a new research, scientists have experimentally demonstrated the advantages that graphene may have over copper for interconnects in future generations of integrated circuits.

There's also a personal favorite of EnergyTechStocks' managing editor, not that he has any money invested in the firm. It's Composite Technologies (CPTC.OB). This company has a patented aluminum composite power line core that can transmit more power than regular copper lines. Yes, it's more expensive, but with not-in-my-backyard (NIMBY) still ever-present, it would seem likely that governments will place a premium on getting more out of existing transmission rights-of-way.

Magnomatics, a Sheffield company which develops advanced magnetic transmission systems and high-torque electrical machines, has signed a six-figure contract with the British Ministry of Defence (MoD), under which it will conduct a detailed design study of a magnetically-geared propulsion motor, based on its patented "pseudo direct drive" (PDD).

Under the contract, the company will develop its technology to the megawatt scale, allowing the MoD to assess its potential for use in electric propulsion systems for future frigates and submarines. The project is due to be completed by April 2010, when the MoD will decide whether to devote more funds to taking the technology further.

The PDD system integrates magnetic gearing in a brushless permanent magnet machine to provide superior performance in low-speed, high-continuous-torque drive applications. It offers the potential for higher efficiencies in a much smaller package than other motor technologies
