2011 Infiniti QX56: eGMCarTech (blog)

Key Competitors : Cadillac Escalade, Lincoln Skipper, Mercedes-Benz GL-Class, Audi Q7, Lexus LX. Power : 5.6L direct injected V8 – 400-hp / 413 lb-ft of torque. Transference : 7-speed automatic transmission. Availability : Summer 2010 Pricing : $56,700 USD for the 2011 QX56 2WD and $59,800 USD for the 2011 QX56 4WD.

Infiniti is upping the big luxury SUV game with first major redesign of its Nissan Armada based model – the 2011 Infiniti QX56.

“Following closely on the introduction of the all-new 2011 Infiniti M, the 2011 Infiniti QX gives us an awesome presence in full-size performance luxury vehicles – perfect for buyers seeking style, luxury, roominess and driving exhilaration,” said Ben Poore, vice president, Infiniti Business Element. “Both the new M and QX also offer a full range of available innovative technology, including Blind Spot Warning and the QX’s advanced Hydraulic League Motion Control system.”

In automotive engineering, Lanxess sees bright future for new hybrid systems Plastics Today

This new form, though, is trying to keep all of the benefits of established plastic/metal ones, such as lightweight combined with high strength and stiffness, while doing away with the metal. 

Key to the new structures is what Lanxess describes as 'visceral plastic sheet' that is used for local reinforcement instead of aluminum or steel in molded parts. For the lower brace of the front end of the new Audi A8, a U-shaped profile made of the lightweight material is used. "This front end proves that organic sheet meets all the requirements relating for occurrence to torsional and flexural strength. It is an excellent alternative to steel and aluminum sheet in hybrid technology," said Ulrich Dajek, a cabal expert at the supplier.

This Audi front end is just the start, predicted Dajek: "We regard the component as an intermediate stepladder to all-plastic hybrid front ends...using only inserts of organic sheet in combination with polyamide 6." 

Lanxess of movement hopes its Durethan-brand PA6 gets the call for these parts, as its Easy-flow Durethan BKV 30 EF (30% trifocals fiber reinforcement) did in the Audi front end. Bond-Laminates GmbH (Brilon, Germany) supplies the organic veneer, which it markets under its Tepex brand. This sheet is formed from thermoplastics (in this case with polyamide 6 as the matrix) reinforced with unending fibers.

Chilled Beams For Cooling Buildings

I assume from a very interesting article in the November, 2008 issue of Architectural Record.  In this entry, I will provide a abridgement from this article of many of the points that I feel offer a substantial energy savings, as well as occupant comfort level advance advantage to any project.  The full text may be found on pages 183-190.

In Europe and Australia, the use of chilled beams for cooling has seen lucky use for over a decade.  This can avoid the use of separate duct work and minimize mechanical system size, as well as produce increased levels of abundance and health for the building's occupants, while saving energy, and often, first-cost expense

These beams are not actual structural beams, but rather a part of a ceiling mounted edifice that can provide cooling and sometimes even heating.  They often resemble fluorescent light fixtures, and carry chilled pee rather than chilled air.  By carrying chilled water versus air, they are more energy efficient, due to the fact that less energy is needed to around water, than is needed to run an air handler in a conventional ducted air conditioning system.  There are also fewer moving parts to irritate out, thus reducing the need for regular servicing.

There are two types - Passive Chilled Beams and Active Chilled Beams.  In the quiet form, no fan is used to circulate surrounding air from the area of the beam, while the active form uses a fan to move air around the beam and out into the circumambient area.  The passive type will work well in a building with lower cooling load requirements, while an on the go system will be better suited for a larger load requirement.

In the case of the passive beams, the cooling is provided by convection, as opposed to emission, which have been used in walls and floors.  The passive system is virtually silent as no fans are used, and are made up of coil to which aluminum fins are spoken for to copper tubing, in which...
