This technology seems to me to be much more beneficial on a local scale, what if every home had its own battery, then home power generation becomes economically more viable for everyone. If you could show that a system like this could pay for itself in say 5 years then every home would want one. Plus for this to be implemented on a large scale requires massive investment that could be decades away. Share the technology and lets get it in homes by next year. Great ted talk. Jon Senior 0 Reply 1 hour ago: I agree 100%. Localised energy production would also make energy consumers more conscious of their consumption and encourage efforts to reduce it. We can invent and invent all we want, but the fast solution to allowing renewable energies to take centre stage is to reduce the base energy draw. With lower baseline consumption, smaller "always on" generators are required to keep the grid operational. Town and house-l

Describing the use of aluminum instead of copper in larger electric motors (example: trains)

"The traction transformer market in North America is driven by the increase in electrification of railways and high deployment of high speed trains in this region. Also the enhancement in the government spending in rail infrastructure is fostering the growth of the North America traction transformers market."

"The retirement of experienced copper industry executives and the lack of trained technical replacements is helping to drive substitution and is likely to lead to more mergers and acquisitions as the industry adapts, senior industry executives said. A group of panelists at Metal Bulletin-American Metal Market's copper seminar in New York this week said that the copper sector needed to be far more proactive in attracting new talent and ensuring the gap in the professional supply chain is filled. "One thing that is driving substitution is the retirement of engineers that were very tied into the thought that copper wiring was the only alternative and that aluminium was unsafe," said Stu Thorn, CEO of Southwire. Thorn said the idea that aluminium was unsafe "almost became a psychological obsession" despite the development of new technologies to make it safe. "Now that generation of engineers is retiring, the new generation coming up doesn't necessarily have that same level of bias [towards copper], but what they do have is the drive to make more money, to reduce costs, and find cheaper alternatives," he told the seminar. "There is a shift..."

WASHINGTON - The U.S. Department of Energy (DOE) has launched the EnergySmart Hospitals initiative, with the aim of increasing the use of energy efficient technologies in hospitals across the United States. \n\nThe EnergySmart Hospital initiative will provide hospitals with design strategies, advanced energy design guides, technology assessments, case studies, training sessions, and an interactive Website to help hospitals increase their energy efficiency. The initiative intends to improve energy efficiency in existing hospitals by 20 percent and to help develop new hospitals that are 30 percent more efficient than current building standards. It will also support hospitals in meeting the challenge of lowering costs while delivering quality patient care and maintaining healthy healing and work environments. \n

"In the past twenty years, more stringent energy codes and environmental standards have led to many higher performance building designs that use less energy. Oftentimes, high performance buildings that incorporate passive building strategies require active occupant engagement [Brown et al. (2009) [1]] but the people who work in these buildings on a daily basis may not comprehend how their actions (negatively or positively) affect the building's energy use [Janda (2009) [2]]. Additionally, minimal research exists surrounding educational strategies for how to best educate building occupants. The purpose of this study was to investigate existing occupant training in high performance buildings to provide recommendations for future occupant education efforts."
