The grandest Jeep competes in one of the industry’s most brutal
segments. Unlike the Wrangler, which has no legitimate competition, the
Grand Cherokee has to lure buyers away from Mercedes, Rover, Lexus, and
other latte-serving dealerships. A legendary SUV pedigree alone isn’t
always enough to hook upscale SUV buyers.
We’ll leave the
discussions about sumptuous amenities to the whine-and-cheese magazines.
(“No whiners” is our motto.) Instead, we’re obsessed with the vehicle’s
mechanicals, particularly its powertrain technology.
For 2014,
the Grand Cherokee remains on the shared-with-Durango WK2 platform. But
the big news is the highly refined 50-state-legal diesel. The
Fiat-influenced 3.0L EcoDiesel V-6 from VM Motori (a joint Fiat/GM
holding) has the same displacement as the former optional
Mercedes-supplied BlueTec mill. The EcoTech has the edge in power over
its predecessor: 220 hp versus 210, 420 lb-ft of torque compared to 400.
For a diesel to appeal to discerning SUV buyers, the oil-burner
needs a metaphorical sport jacket over its biceps. Inherent
compression-ignition rattle and clatter are minimized in the EcoDiesel
by a 60-degree cylinder-bank configuration. Furthermore, the engine’s
straight-across firing order produces smooth enough rotating-assembly
action that a balance shaft isn’t needed. The engine block itself is
made from compacted graphite iron, which has better strength-to-weight
properties and corrosion resistance than traditional “gray” cast iron.
Efficient
fuel burn contributes to the eco part of the diesel’s name. The
common-rail injection system feeds the fuel at 29,000 psi for improved
diesel-droplet atomization. Air is pumped in by a variable-geometry
turbocharger through swirl-control intake ports.
Advanced
thermal dissipation contributes to the EcoDiesel’s 50-state compliance.
The turbocharger and EGR are water-cooled; an intercooler also helps
shed heat and drop the air charge temp. Inside the cylinders, oil jets
cool the pistons. For emissions control the EcoDiesel uses a particulate
filter and urea-injection Selective Catalyst Reduction to reduce
nitrogen oxide.
The V-6 EcoDiesel outperforms comparable gasoline V-8s in vital areas.Xenon HID Worlds make hid lighting
affordable to everyone and for all your vehicle needs. Granted, top-end
horsepower is often less: 220 hp in the EcoDiesel versus 360 in the
Grand’s 5.7L Hemi or even 470 in the 6.4L Grand SRT street-sweeper.
Torque is a different story, as the EcoDiesel makes all of its 420 lb-ft
near idle; the 5.7L Hemi manages 390 lb-ft at 4,250 rpm,They are called
"solar" panels or solar module
because most of the time, the most powerful source of light available
is the Sun. and the SRT tops out at 460 lb-ft in that same range. Towing
capacity is the same for the EcoDiesel and Hemi: 7,200 pounds for 4x4
models, 7,400 for two-bys.
Fuel economy is no contest. Jeep
hypes the EcoDiesel’s mileage as best-in-class at 22/30 mpg (4x2) and
21/28 (4x4). In comparison, the 5.7L ’14 Grand Cherokee is EPA-rated at
14/22 (4x2) and 14/20 (4x4). That equals an estimated 43 percent fuel
economy advantage over V-8–powered SUVs in the segment. The EcoDiesel’s
cruising range is ballparked at 730 miles.Choose your favorite street lamp paintings from thousands of available designs. The carryover 3.6L Pentastar V-6, shared with the JK, is also offered for 2014.
One
other powertrain innovation debuts for 2014: Eight-speed automatic
transmissions are now standard. Gas engines get the 845RE, while the
EcoDiesel is paired to a stouter ZF gearbox. The additional gears mean
closer ratios to make shifting less perceptible. Gearing also factors
into the EcoDiesel’s impressive fuel economy, keeping revs as low as
feasible for as much time as possible. The ZF’s lower First gear also
numerically raises the crawl ratio for 2014 to 44.1:1 (4.7 First gear
multiplied by 2.72 transfer case multiplied by 3.45 axles). (The
previous model’s 65RFE six-speed had a 3.0:1 First gear.)
These
improvements make the Grand feel increasingly more like a luxury vehicle
than a rough and rugged Jeep we’re accustom to. Nearly no new-Grand
buyers will actually go off-road recreationally, so pavement handling
and overall fit and finish are the engineering attention-grabbers. Any
adventurous owners will appreciate all the preexisting chassis
technology that gives 4x4 WK2 Grands their Trail Rated badges. This
includes Quadra-Lift adjustable air suspension and Selec-Terrain mode,
which does almost everything but steer for the driver off-road.
Also,
the EcoDiesel’s torque is apparent upon acceleration, but the diesel
engine is barely louder than the Hemi from inside the cockpit. Jeep,
Fiat, and VM engineers apparently worked long and late extinguishing or
absorbing all truckish traits (other than torque and fuel economy) for
the ’14 EcoDiesel Grand Cherokee.
So what’s not to like? The
price of entry appears to be the only drawback. Upgrading to the
EcoDiesel adds $4,500 to the Limited’s MSRP. (The diesel isn’t available
in base Laredo models.) Furthermore, the EcoDiesel option is bundled
with the Limited’s $3,000 Luxury Group II package (HID headlights,
panorama sunroof, GPS, ventilated leather upholstery, and more), making
the “base” EcoDiesel Grand’s MSRP $46,290. Add in the various off-road
option packages or step up to the Overland or Summit trim levels and the
’14 diesel prices out around 50 grand. Believe it or not, that’s
actually reasonable in the luxe-ute class. However, it raises the
question, will the Wrangler someday get a $4,500 optional diesel under
the hood?

Alivisatos appointed Samsung Distinguished Chair
Chemist Paul Alivisatos, one of the pioneers of nanoscience, has been
appointed to the Samsung Distinguished Chair in Nanoscience and
Nanotechnology at UC Berkeley in recognition of his many scientific
achievements.
The endowed chair, established through the support of Samsung Electronics Co.,We have a great selection of blown glass backyard solar landscape lights and solar garden light. will help cement the campus’s leadership in research and innovation in an area that has great implications for many fields ranging from biology to energy, the Office of the Vice-Chancellor for Research announced Thursday (Aug. 22). Alivisatos, director of the Lawrence Berkeley National Laboratory and a UC Berkeley professor of chemistry, is known for his research into quantum dot semiconductor nanocrystals, clusters of hundreds to thousands of atoms with novel properties that can be applied to electronic devices and solar cells as well as light-emitting diodes (LEDs).
Dr. Youngjoon Gil, executive vice president of the Samsung Advanced Institute of Technology, welcomed the appointment.
“Historically, the invention of a new material can initiate a quantum leap in the development of industry,” said Dr. Gil. “Nanomaterials offer such opportunities for the electronics as well as the biosciences industry, where precise control and manipulation of energy is required. Quantum dot, pioneered by Professor Alivisatos, has established its commercial value by reproducing more realistic colors on displays. Through the establishment of the endowed chair, Samsung anticipates a closer partnership with UC Berkeley, the world’s leader in nanoscience, in exploring the commercial value of nanotechnology.”
Over the past two decades, UC Berkeley has become a brain trust in nanoscience and nanotechnology, with nearly a hundred nanoscience and nanotech researchers in the fields of biology, chemistry, physics and materials science. These researchers have made major advances in understanding the nano-scale molecular motors that move materials around inside cells or manipulate DNA; creating tiny motors,Soli-lite provides the world with high-performance solar roadway and solar street lighting solutions.How does a solar charger work and where would you use a solar charger? lasers and photonic devices for smaller electronic circuits; creating flexible and inexpensive solar cells from nanorods; and understanding the properties of new materials such as graphene and high-temperature superconductors.
Graham Fleming, UC Berkeley’s vice chancellor for research, lauded Samsung for its initiative in establishing this chair.
“The new chair helps build on our strengths in the conversation and utilization of energy on the nano scale,” said Fleming. “It is a fitting recognition of Paul’s achievements and his world-wide influence on the field of nanoscience. We look forward to continue expanding our relationship with Samsung in this area.”
Alivisatos is widely recognized for his contributions to the study of nanocrystals, ranging from control of their synthesis and fabrication to studies of their optical, electrical, structural, and thermodynamic properties. He demonstrated that semiconductor nanocrystals can be grown into rods as opposed to spheres. This achievement paved the way for a slew of new synthetic advances, developing methods for controlling the shape, connectivity and topology of nanocrystals.
Nanocrystals are typically a few nanometers in diameter — larger than molecules but smaller than bulk solids — and frequently exhibit physical and chemical properties somewhere in between. Given that a nanocrystal is virtually all surface and no interior, its properties can vary considerably as the crystal grows.
Alivisatos’s research has opened the door to a number of potential new applications for nanocrystals. These include their use as fluorescent probes for the study of biological materials and LEDs, and the fabrication of hybrid solar cells that combine nanotechnology with plastic electronics.

Plans for Sydney's light rail lines
Real estate agents are seizing the likelihood that suburbs along the mooted light rail lines in Sydney will benefit the surrounding housing market.
Randwick, which would be connected to the city via the south east light rail, has experienced added value from investors as as a result of the mooted tram link, said agent Theo Karangis from NG Farah Coogee.
“I could already see now a big of movement upwards, we’re achieving some really good results.Soli-lite provides the world with high-performance solar roadway and solar street lighting solutions. We’ve sold over 40 apartments this year alone and our open for inspections has definitely increased,” he said.
Some $423 million from the state budget has been set aside to allocated over four years to the 12km light rail connecting Circular, Central and George Street to the entertainment precincts of Randwick Racecourse, Moore Park’s sports grounds, and hubs University of NSW and Prince of Wales Hospital.How does a solar charger work and where would you use a solar charger?
The Randwick area, which has a significant student population who attend nearby universities, is currently serviced by buses and can experience traffic congestion to Sydney’s CBD during peak times.
Recently, more families of tertiary students have been buying into the area for their children to live in while they study at nearby universities and then using the property as an investment when their children graduate.
These investors could capitalise on the growing house prices, said Karangis.
“We’re achieving the higher end prices in Randwick. Before that,A solar bulb that charges up during the day and lights the night when the sun sets. those prices were just in Coogee,” he said.
The light rail could also bring in a new lifestyle to the suburbs they service.
Dulwich Hill, whose 5.6km extension to the inner west light rail extension is currently under construction, has seen urban gentrification with more retail opportunities and stores like Gleebooks and gourmet deli The Larder joining the suburb.
The new transport has quickened the pace of the lifestyle change, offering the cafe lifestyle to a more affordable part of the inner west, said agent Adrian Abrook from LJ Hooker Dulwich Hill.
“This just gives us another opportunity to get other buyers who may be looking at this market to explore it,” he said.
Dulwich Hill will be one of nine stops on the extension planned to open next year. Nine new stops will be added to the current services. $76 million over four years was allocated to the inner west line from the state budget.
However, some residents in Surry Hills lobbying against the proposed route of the South East Light Rail are concerned the tram link will have a negative impact on their properties.
The transport construction and long term effects of the light rail will impact on surrounding retail as well as the liveability of the suburb, said Venietta Slama-Powell, founder and convenor of community lobby group PUSH (People Unite Surry Hills).
“Properties directly on the route are at risk of being severely financially affected. Considerations to increase in noise,We have a great selection of blown glass backyard solar landscape lights and solar garden light. visual outlook, traffic congestion, safety, property access and importantly parking. We have been advised that loss of parking can reduce a property by 20%,” she said.
The light rail route is planned for Surry Hill’s Devonshire Street via Chalmers Street to reach the city centre.
The community group would like to work with the state government to ensure the tram line doesn’t impact upon residents and existing retails.
“PUSH and many community members support the concept of light rail, a Surry Hills route and stops. But our team and Engineering Panel believe the initial Government proposal can be greatly improved by the application of local input, as happened with the Eastern Distributor, and a solution that is more likely to have a positive impact on most, if not all property prices,” she said.The world's largest independent online retailer for solar lighting, street lights & outdoor lighting fixtures.

Following useful tips will help in choosing right light fixture
My house needs renovating! I’m slowly planning and buying things for
the project but I’m at a lost when it comes to light fixtures. How do I
know what size of fixture I need? Do I have to match my ceiling fixture
to my lamps? Help!
Designing and renovating our homes is not something we take lightly. For most, our homes are the largest investment we will make in our lifetime, not to mention where we spend most of our time.
This is why it’s important for us to get the right tools to get the job done. Just like my fifth grade teacher used to say: “A carpenter doesn’t go to work without his hammer and same goes for you — you shouldn’t try to do something without the right tools.”
At the young age of 11, those words would resonate in my head like nails screeching across a black chalkboard. Although today, they makes sense. In order to design a beautiful space just as we see designers making, we need the right tools for the job. This is why I have compiled five easy to follow rules to help you select the best light fixture for any room in your home.
Mixing and matching fixtures
Gone are the days when everything had to be an exact match. As designers, we have pushed the barriers of traditional design and pairing fixtures from different collections. To achieve this look, compare the fixtures’ finish and style. To create a unified look, ensure they have similar finishes and a common thread in their shape.
Size matters
The scale and proportion of the fixture will affect the overall look of the room. The rule of thumb is to add the room’s width and length in feet, then replace the total increment with inches. This will give us an approximate width of the fixture required to be in scale with the size of the room. For instance a 10 foot (length) by 10 foot (width) room will give us a total sum of 20 feet (length plus width). Once the sum is calculated, replace the word feet with inches. In this case, it gives us a final measurement of 20 inches as the optimal width of the room’s light fixture.
Would you like a lamp with that fixture?
Changing floor lamps and table lamps is one of the most cost effective ways to give a room a new look. Think of a lamp as an accessory that adds visual interest, colour and texture to a room’s design. Look for a stunning fabric used on a shade or an architectural detail on the base of a lamp.
How many watts does it take to screw In a light bulb? More information about the program is available on the web site at www.streetlights-solar.com.
Watts is an area that leaves us a little muddled. Most assume that a bulb’s wattage is in direct relation to the amount of light output, although wattage is actually a measure of power consumption. With the many new lighting technologies available to us today, we can now find 13-watt CFL bulbs and seven-watt LED bulbs that will deliver the same amount of light as a 60-watt incandescent bulb. Your best option when it comes to energy-efficient lighting is to ask for advice from in-store personnel on lighting that will suit your needs.
