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

"At a time when Iran's economy is tied up with sanctions, limiting its international trade capacities, it managed to sell more than a million vehicles (885,000 passenger vehicles and 128,000 light commercial vehicles) in 2012, enforce Euro IV norms in 8 cities including Tehran, Karaj, Arak, and Tabriz, convert all public cars into Compressed Natural Gas (CNG) compliant vehicles, and successfully implement a vehicle scrappage program to get very old, highly polluting vehicles off the streets of Iran. The prospect of such a country opening up to trade, giving an opportunity for global automotive companies to be a part of its growth, certainly creates buzz in the industry. Iran sold close to 860,000 passenger vehicles in 2014, 88% of which were sold by Iran Khodro Industrial Group (IKCO) and SAIPA under different marquees. With around 11.7 million vehicles on the road, the aftermarket potential is massive and the average age of vehicles is steadily increasing."

If you watch The Green Optimistic you already know that we covered air cars in previous posts, both MDI CAT's and the Angelo DiPietro air motor. The first time we wrote about these inventions was about 6 months ago. Now, MDI and Angelo DiPietro have contracts all over the world with auto makers to sell them the compressed air technology

PKE is the new range of ECO Coils&Coolers branded air condensers launched by Luvata for commercial AC and refrigeration applications. It is the enhanced offspring of the PCE range (currently phasing out), with improved efficiency and optimized sound emission parameters. Like all ECO Coils&Coolers ventilated units, even the PKE range is available for CO2 applications. The PKE offers an improved hauling and fastening system, thanks to new features. Moreover, the side panels are removable allowing easy access to the units' internal compartments, which have been increased by 120 mm. In order to facilitate maintenance and service, the PKE range has also been equipped with special door holders with a hold open feature. For models with 4 and 5 fan motors, the number of doors has been reduced and the width has been increased, as to allow easy access to the internal components. Lastly, the base has been reinforced for particularly difficult installations. On the other hand, thanks to a compartment incorporated with the condenser to enclose the compressing and the electrical control units, called housing, the PKE range does not require long connection pipe-work, thus reducing the risk of possible leaks. The special internal surface of the compressor compartment has been designed so as to increase sound absorption, reveals the company's press release.

You've heard of hybrids, electric cars and vehicles that can run on vegetable oil. But of all the contenders in the quest to produce the ultimate fuel-efficient car, this could be the first one to let you say, "Fill it up with air." That's the idea behind the compressed air car, a vehicle its backers say could achieve a fuel economy of 106 miles per gallon. Plenty of skepticism exists, but with many Americans trying to escape sticker shock at the gas pump, the concept is generating buzz. The technology has been the focus of MDI, a European company founded in 1991 by a French inventor and former race car engineer. New York-based Zero Pollution Motors is the first firm to obtain a license from MDI to produce the cars in the United States, pledging to deliver the first models in 2010 at a price tag of less than $18,000.

Unable to retrench like their unregulated counterparts, utilities are investing more than they were just a few years ago while paying record spreads over risk-free rates for financing. At the same time, revenues are under pressure due to softening power prices and an economically driven drop in demand. The past three months have seen a 1.8 per cent drop in US power usage versus the same period a year ago, according to the Edison Electric Institute. Adding insult to injury, Macquarie Research reckons regulators might become less generous when setting rates since compressed Treasury note yields may be used to justify a lower regulated return on equity.

SureWest had said it was contemplating such services when the company began offering broadband via bonded ADSL2+ in its incumbent territory last fall, including 10-megabit-per-second services. The company already offers IPTV through its fiber-to-the-premises network, but its bonded ADSL2+ customers have so far only had access to SureWest's voice and data services. (The company has offered IPTV over copper on a very limited basis even before it began line bonding. It offers IPTV over copper to about 2500 customers today, mostly to those with short loops and modest standard-definition video needs.) The new copper-based IPTV services, which will be available to 15,000 homes in December and another 10,000 by next June, are enabled in part by the company's recent switch from Minerva middleware to Microsoft's Mediaroom and by its use of MPEG-4 encoding for video compression.

"Nicopress®, the inventor of the oval sleeve, will address the common rigger question: "Are aluminum sleeves equal to copper for wire rope terminations?" at its white paper presentation at LDI 2014 at 1:30 p.m., Sat., Nov. 22, room N210."
