China's Jaw dropping Supersonic Submarine which can travel 6,000 miles in just 100 minutes!

Researchers in China are reporting that they’ve taken a big step
towards creating a supersonic submarine. This technology, which
could just as easily be applied to weaponized torpedoes as military
or civilian submarines, could theoretically get from Shanghai to San
Francisco — about 6,000 miles — in just 100 minutes. If all this
doesn’t sound crazy enough, get this: This new advance by the
Chinese is based on supercavitation , which was originally developed
by the Soviets in the ’60s, during the Cold War.
As you may already know, it’s a lot harder for an object to move
quickly through water than air. This is mostly due to increased drag.
Without getting into the complexities of fluid dynamics, water is
simply much thicker and more viscous than air — and as a result it
requires a lot more energy for an object to push through it. You can
experience the increased drag of water yourself next time you’re in a
swimming pool: Raise your hand above your head, and then let it
fall towards the water. (Or alternatively, if there are people
sunbathing nearby, do a belly flop.)
Anyway, much like a small-engined car is ultimately limited by its
ability to cut through wind resistance (drag), a submarine or
torpedo needs insane amounts of power to achieve high velocity
through water. This is why, even in 2014, most submarines and
torpedoes can’t go much faster than 40 knots (~46 mph). Higher
speeds are possible, but it requires so much power that it’s not
really feasible (torpedoes only have so much fuel).
How a normal torpedo works, vs. a supercavitation torpedo
Enter supercavitation, a technique devised by the Soviets in 1960
with the explicit purpose of creating high-speed torpedoes.
Supercavitation gets around the drag of water by creating a bubble
of gas for the object to travel through. The USSR’s research
resulted in the Shkval torpedo, which uses a special nose cone to
create the supercavitation envelope, allowing it to travel through the
water at speeds of up to 200 knots (~230 mph, 370 kph) — much,
much faster than the standard torpedoes fielded by the US.
The only other countries with supercavitational weapons are Iran
(which probably reverse-engineered a Russian Shkval), and
Germany with its fantastically named Superkavitierender
Unterwasserlaufkörper (“supercavitating underwater running body”).
The US is researching its own supercavitational torpedo, but there’s
very little public information available.
Which brings us neatly onto China. Unlike previous approaches,
which have to be launched at high speed (~60 mph) to create the
initial supercavitation bubble, the method described by the Harbin
Institute of Technology in China uses a “special liquid membrane”
that reduces friction at low speeds. This liquid is constantly
showered over the object to replenish the membrane as it’s worn
off by the water. Once the torpedo/submarine/vessel gets up to
speed, it sounds like it uses the same gas-through-nose-cone
technique to achieve supercavitation. (Details are a bit vague at this
point.)
Read our featured story: The science of beam weapons
In theory, supercavitation could allow for speeds up to the speed of
sound — which, underwater, is a heady 1,482 meters per second, or
3,320 mph. At that speed, you could go from Shanghai to San
Francisco (about 6,000 miles) in well under two hours. Suffice it to
say that there isn’t a country in the world that wouldn’t love to have
a submarine that can circumnavigate the world in half a day —
especially a country with nuclear missiles, like China, Russia,
France, the UK, or the US.
The nose cone of a Russian Shkval (Squall) torpedo. Note the vents
for escaping gases, which combined with the flat nose create a
supercavitation bubble.
In practice, though, it’s a) very difficult to steer a supercavitating
vessel (conventional methods, such as a rudder, won’t work without
water contact) — and b) developing an underwater engine that’s
capable of high velocity over long distances is very, very difficult.
You can’t use a jet engine underwater, sadly — and generally,
rockets only have enough fuel for a few minutes, not hours. Nuclear
power might be a possibility as far as supersonic submarines go,
but that’s just a guess.
Li Fengchen, a professor at the Harbin Institute, says their
technology isn’t limited to military use. Yes, supersonic submarines
and torpedoes are top of the list — but the same tech could also
boost civilian transport, or even boost the speed of swimmers. “If a
swimsuit can create and hold many tiny bubbles in water, it can
significantly reduce the water drag; swimming in water could be as
effortless as flying in the sky,” says Li.
As always with such advanced (and potentially weaponized)
technology, it’s hard to say how far away it is from real-world use.
If civilian researchers are making good progress, then it’s a fairly
safe bet that the military is even further along. Wang Guoyu, another
Chinese researcher, told the South China Morning Post: “The
primary drive [for supercavitation] still comes from the military, so
most research projects are shrouded in secrecy.”

Nexus 7 integrated in heart of Toyota's New Car!

When it comes to the average driver, one's car infotainment center might be of more importance than the engine under the hood. Given that technology is ever-changing and one is far more likely to update to new tech hardware long before investing in a new car, it only makes sense that an infotainment system should facilitate that reality.

Such is the nature behind Toyota's new Intelligent System (TIS for short), and at the heart of the infotainment system is the Nexus 7. The auto maker has partnered with ASUS and Unimax to create the new TIS offering, though it appears that the system is only destined for Taiwan (for now, at least)

The TIS infotainment center is a Nexus 7 tablet decked out with everything a driver will need, such as navigation that utilizes a 4G connection, voice recognition, and multi-media offerings for controlling audio in the car. With the tablet and overall system, users will be able to use Google Maps and other things they may do with their tablet presently.

When the Nexus 7 becomes outdated, different tablets can be made in the future that can be swapped into the infotainment center, allowing drivers to keep their vehicle up-to-date. In addition, drivers can use NFC to connect their smartphone or other device for navigation or music.

When cars will surface offering TIS isn't yet known.

The New Subaru Impreza Hatchback!

It may not be an obvious choice for most buyers, but this four-wheel
drive, sub-£20k hatch does have merit This is the new Subaru
Impreza hatchback. It's the same car that was launched in Japan at
the end of 2012, but hasn't pitched up here until now as the UK
importer has been battling unfavourable exchange rates. The Yen vs
sterling situation is now sorted, though, and so here is the more
humdrum hatch. Two versions are available, both using the same
112bhp 1.6-litre flat-four engine but equipped with either a five-
speed manual transmission or a CVT, dubbed Lineartronic.Prices
start at a commendable £17,495 for the Impreza RC in manual form,
rising to £18,995 for the CVT, which has slightly more favourable
CO2 emissions and better official fuel economy at 140g/km and
46.3mpg respectively. It's the CVT version we've tested here.A lack
of other engine choices means the Impreza immediately appears
hobbled compared to the choices available on direct rivals such as
the Focus, Astra and Golf.Yet it does go into battle with some
traditional Subaru signatures. For example, its petrol engine sends
its power to all four wheels – a rather exotic attribute for a sub-
£20k hatchback. On start-up it sounds like a mildly muted version
of the STi's turbocharged flat-four, which is either pleasing or a little
unwelcome depending on your personal taste.It settles down to a
rather refined note for a flat-four though. The trouble is that is needs
a lot of stirring in order to extract any overtaking urge, and if you
need to get up to cruising speeds quickly you need to be quite
brutal with the throttle. In truth, the optional CVT seems mostly to
blame. It's one of those infuriating examples of the breed where
engine speeds rise faster than road speeds; a sort of slipping clutch
reaction every time you put your foot down. Yes, the 'box makes
small positive difference to mpg and CO2 emissions but the manual
instinctively feels like the one to order. Predictably, grip and traction
are good, though we only sampled this Impreza on dry roads. Even
so, the chassis doesn't feel like it's going to be trouble by the 1.6's
power and torque. It's comfortable too. There is some road noise
and a slightly stiff-legged town ride but it settles down at 40-50mph
and stays pliant. One common flaw of Subaru cabins is that they
lack the design flair and quality of the best of the breed. The
Impreza's, true to form, doesn't have the same lustre as you'll get
from, say a VW Golf or Peugeot 308, especially when you cast your
eyes downward. Yet most of the bits that you see and touch are of
decent quality.The controls too are the nice'n'simple variety -
chunky rotary knobs for the heating and the like. They're easy to
use but look rather dated. Comfort is good though, thanks to a flat,
supportive seat and good adjustment, while fore and aft visibility is
better than in most. Space for you, your three passengers and
luggage is good without being exceptional.In fact, good without
being exceptional is the lasting impression of the Impreza. Like for
like, you'd be unwise to consider this instead of a Golf, Focus, or
nearly any other mainstream hatch. And there's no doubt that for a
good sway of company funded buyers not having a diesel is a huge
drawback. Yet, there's no doubt that having four-wheel drive for this
price is an attraction in some parts of the country and that
combined with Subaru's reputation for making hardy, hard-wearing
cars is a compelling choice. So if it's for you it's for you. It's just
not the first (or second) choice for most of us.

2015 Aston Martin Vanquish: Bringing Reality to the Unreal

The worst aspect of cutting edge CGI and audio technology in
today’s world is that it’s taught us to question our primary senses.
We’ve seen and heard so many (apparently) realistic portrayals of
colossal robots, epic space travel and earth-shattering destruction
we’ve instinctively developed an inner voice that pipes up whenever
we witness the fantastical. The message? “Sure, that looks and
sounds amazing, but of course it’s not real.” While this voice is
usually an asset, helping us separate fantasy from reality, its
skeptical nature can be a burden when you’re piloting a spectacular
supercar through the equally spectacular Scottish Highlands. Under
these circumstance, ideally, one turns off all brain filters and simply
drinks in the natural and mechanical eye candy.
Such was the case during a recent road test between Loch Ness and
the North Atlantic Coast in a 2015 Aston Martin Vanquish. In this
circumstance, immersed in the visceral ambience of Aston Martin’s
premier performance coupe while traversing the visual tapestry that
is northern Scotland, one might reasonably question one’s
surroundings. Peering through the Vanquish’s sloped windshield
reveals deep blue lakes and lochs nestled between jagged
mountains bathed in lush greens and deep grays. Throw in an
uncharacteristic partly-to-mostly-sunny sky and you’re convinced
it’s all some grand illusion the folks at Aston Martin orchestrated to
emphasize the Vanquish’s latest improvements.
Of course driving an Aston Martin, in any atmosphere, can inspire
disbelief. “Is the 6.0-liter, V12 engine really capable of such operatic
sound quality?” was a question I quickly processed and dismissed.
I’ve driven enough Aston Martins to know the unrivaled quality of
their exhaust notes. “Is a car as luxurious and substantial as the
2015 Vanquish really capable of zero-to-60 mph in 3.6 seconds?
Can the V12′s 568 peak horsepower actually push the sinuous
coupe to over 200 mph?” That question took a bit longer to unravel
than the exhaust query, because among the Vanquish’s
improvements for 2015 is an all-new 8-speed transmission that
maximizes every one of the V12′s 568 horses and 465 pound-feet of
peak torque.
If you’re lucky enough to have first-hand experience with last year’s
Vanquish (count me among that fortunate group) you’ll notice the
performance upgrades immediately. The previous car certainly
wasn’t slow, with a zero-to-60 time of around 4.1 seconds, but that
half-second improvement to the 2015 Aston Martin Vanquish’s
acceleration can be felt even without mashing the gas pedal because
of newfound immediacy to throttle response.
The Vanquish always maintains its stately nature, but switching
from the 6- to 8-speed transmission for 2015 means tighter gear
ratios, and that means things happen much quicker when your right
foot seeks forward movement. Like every modern automaker, Aston
Martin isn’t simply chasing more horsepower these days (though
the Vanquish’s V12 did gain 3 horsepower and 7 lb-ft of toque
through engine tweaks for 2015).
More horsepower brings with it more heat and, quite often, reduced
fuel efficiency. Better to leverage the existing power in the most
effective way possible, which is exactly what the new, rear-mounted
ZF 8-speed transaxle does. While the transmission utilizes a
traditional torque converter rather than a dual-clutch design, shifts
happen in as little as 130 milliseconds when the Vanquish is set to
“Sport” mode, a setting that also quickens throttle response and
puts the transmission in a more aggressive shift mode.
Connecting the engine and transaxle is an aluminum torque tube
meant to reduce parasitic loss through its lightweight design and
fixed link (no u-joints involved). These drivetrain upgrades have
accomplished the trifecta in automotive evolution — higher
performance, improved refinement and superior fuel efficiency.
Along with more power, quicker acceleration and a greater top
speed, the Vanquish’s EPA ratings move from last year’s 13 city/19
highway mpg to 13 city/21 highway mpg.
The 2015 Vanquish’s ride and handling behavior has been similarly
upgraded through a series of chassis revisions. The front and rear
springs are stiffer by 15 and 35 percent, respectively. The rear
bushings are also 20 percent stiffer and a stronger rear anti-roll bar,
as well as updated camber and toe settings, reduce body roll while
improving turn-in. New, lighter 10-spoke forged wheels now ride on
upgraded Pirelli PZero tires (255/35-20 front, 305/30-20 rear), and a
larger dynamic spread between the Normal, Sport and Track
settings for the adaptive suspension give the Vanquish a shaper,
more nimble demeanor than one expects from a plush grand-
touring coupe. Additional changes for 2015 include new leather trim
color options (Dark Knight and Fandango Pink ) and a new Diavalo
Red exterior paint.
Of course, with the just-introduced Q by Aston Martin bespoke
service Aston Martin buyers now have an almost unlimited number
of personalized options available to them. The range of vehicle
customization goes far beyond simply color-matching the leather
seats to your wife’s favorite nail polish hue. If you’re looking to
create a Vanquish like no other, Aston Martin has a team of
designers ready to assist you. The cost for this service adds to the
2015 Vanquish coupe’s starting price of $287,820 ($305,820 for the
Vanquish Volante convertible).
Better performance and fuel efficiency? Nimble handling from a
palatial luxury coupe? A personalized program to build a supercar
reflecting your specific tastes? Like today’s CGI, these concepts
might have your little voice piping in, suggesting it all looks and
sounds great — and unreal. But just like the mind-altering vistas I
drove through in the Scottish Highlands, the 2015 Aston Martin
Vanquish represents unfiltered reality.

A big milestone in automobile tech


This isn't just any old Lego car, it's not even just
a life-sized Lego car; it's a fully functional, air-
powered, full-sized Lego car.
This car is made of 500,000 pieces of Lego and
features 256 working pistons that drive its
functional engine. It uses four orbital engines to
power the car up to speeds of 20mph.
The Lego car was built by Australian Steve
Sammartino and Romanian Raul Oaida and styled
to look like a hot rod. At the moment they've kept
speeds down saying they "drive it slow as we are
scared of a giant Lego explosion." We’d like to
see that shot in super slow-motion. They have
posted a normal video of it in action on YouTube
though.
