Titanoboa: Monster Snake


Titanoboa: Monster Snake

Aug192012
Millions of years after the fall of the Dinosaurs lived a species of snake that is unimaginable, unbelievable, and truly mind-blowing.
60-58 millions years ago in the swampy jungles of Colombia, lived Titanoboa (meaning Titanic Boa): a massive 48 foot long2,500 pound snake. Disturbing isn't it?
Titanoboa's size could be attributed to the climate it lived in. Warmer climates usually meant more vegetation, which resulted in prey that often grew bigger than most that lived in cooler conditions.
T-shaped spines and mega vertebrae, compared to snakes of today.
This colossal snake looked something like a modern-day boa constrictor, but acted more like today’s Amazon-based anaconda. It was a slithery swamp dweller and a tremendous predator, able to eat any animal that it hunted. The diameter of its body would be close to being as high as a man’s waist.

In this swampy jungle of an oasis, life was surprisingly large due to the heavy non stop rain fall, bountiful vegetation and life in the area. Deep water from rivers flowing snaked around palm trees, hardwoods and occasional ridges/hills of earth.
The river basin in which Titanoboa fed, held turtles with shells twice the size of manhole covers and crocodiles – at least three different species – at more than a dozen feet long. Also living at that time were 7 foot long lungfish, two to three times the size of their Amazon cousins of this day.
And for the sake of size comparison:

The Unforgettable Cars of the '90s Pt. 1 [30 Pics]

Oct312012
This is going to be a multi-part series as there are just too many icons from the 90's era that we believe deserve our attention. Here are five that we wanted to start the series with.

Ferrari F40

Ferrari F40 Silhoutte
At the time of its release in 1987 it was the fastest, most powerful, and most expensive car that Ferrari sold to the public (yes that's before the 1990's, but its production continued through until 1992). Only 1,315 F40's were ever produced which makes them one of the most desirable Ferrari's ever made.
Ferrari F40 Front
The F40 had impressive figures like a 0-100 km/h time of 4.1 seconds and a top speed of 324 km/h (201 mph). The powerplant was a 2.9L twin-turbo V8 that produced 471 hp (352 kW).
Ferrari F40 Blue Chrome
It was designed by Leonardo Fioravanti, of the Pininfarina car design firm. He was also the man behind other Ferrari icons like the Daytona and the 288 GTO.
Ferrari F40 LM Front
F40 was the first legal production car to break the 320 km/h (200 mph) barrier. It remained there until the release of Lamborghini Diablo in 1990.
Ferrari F40 Top
The body was an entirely new design by Pininfarina featuring panels made from kevlar, carbon fiber, and aluminum for strength and weight reduction. Extensive aerodynamic testing was also employed.
Ferrari F40 Interior
Weight was further minimized through the use of a plastic windshield and windows. Although the cars did have air conditioning, no carpets, sound system, or door handles were installed.
Ferrari F40 Prototype Rear
The F40 was designed with aerodynamics in mind. For speed the car relied more on its shape rather than its power. Frontal area was reduced, and airflow greatly smoothed, however stability rather than terminal velocity remained a primary concern.

Jaguar XJ220

Jaguar XJ220S Yellow Front View
When it was released in 1992 it was the fastest car in the world (350 km/h, 217 mph), and held the record until the release of the McLaren F1 in 1994. Only 281 road cars were ever produced.
Jaguar XJ220 Engine
Originally the XJ220 was supposed to be powered by a massive 6.2L V12 engine which was later scrapped in favour of the 3.5L twin-turbo V6. The engine delivered an explosive 542 hp (404 kW) to the rear wheels.

The price of the car fluctuated during its sale period due to the global recession. The car was officially announced in 1989 with the revised specification and a price of £361,000 ($580,000 USD). Prospective buyers were asked to put up a deposit of £50,000 (US$80,000) to be put on the waiting list for delivery.

XJ220 also held the Nurburgring production car lap record, between 1992 and 2000, at 7:46:37, driven by John Nielsen. This was 30 seconds faster than the previous production car lap record and was held for eight years!
Jaguar XJ220 Side View
Jaguar took 1,500 orders for the car in a frenzy of bidding (taking £17m in deposits in one day) and had to whittle the order book down to just the 350 promised, which it did on the basis of 'first come, first served'.
Jaguar XJ220S Rear Side
Although the XJ220 was not built in compliance with the Federal Motor Vehicle Safety Standards of the United States, it has since become possible to privately import it to the US under the "Show and Display" exemption.

Dodge Viper GTS

The GTS was designed to be a "weekend warrior's" track machine, able to compete with most of the exotics of the time, while coming in at a fraction of their cost.
Chrysler corporation sold almost 10,000 of these to the public. It was powered by a massive naturally aspirated 8.0L V10 engine that output 450 hp (336kW). [Viper photos by: Rasidel Slika].

The Viper was able to achieve a 0-100 km/h time of 4.0 seconds without the aid of any forced induction (superchargers and/or turbochargers).
Dodge Viper GTS Front
Viper's slightly raised roof above the seats was specifically designed to be able to fit helmets, a throwback to its intended purpose.
Dodge hired Carrol Shelby as a "Performance Consultant" to aid in Viper's unique and truly timeless design which makes it a very thought after car of the 1990's for us.

Porsche 911 GT1

The GT1 was a car designed for competition in the GT1 class of sports car racing, which also required a street legal version for homologation purposes. The limited-production street-legal version was labeled the 911 GT1 Straßenversion (Street version).
Porsche 911 GT1 Engine
A mere 25 cars were produced and sold publically, making the GT1 and extremely rare car to come by in its road worthy form.
Porsche 911 GT1 Side
The car was powered by a Porsche 3.2L Flat-6 twin turbo engine (that had to be de-tuned for road use) which produced around 537 hp (400 kW).
Porsche 911 GT1 Interior
GT1 could accelerate to 100 km/h (62 mph) from a standstill in 3.9 seconds on its way to a top speed of 308 km/h (191 mph).

Ford GT90

Ford GT90 Front
Performance included a top speed of 235 mph (378 km/h), which enabled the car to complete the quarter mile in 10.9 seconds. The 720 hp (537 kW;730 PS) came from a quad-turbocharged 6.0L V12 DOHC engine.
Ford GT90 V12 Engine
The single V12 was based on two Lincoln V8 engines. The last pair of cylinders from the rear of the first engine and the first pair of cylinders from the front of the second engine were removed, at which point both engines were welded together.
Ford GT90 Side View
The GT90 was built by a small team in just over six months and, as a result, borrowed many components from another high profile stablemate—the Jaguar XJ220 (the car mentioned in this article). The all-round double wishbone suspension and the five-speed manual gearbox were the main components to come from the XJ220.
Ford GT90 Rear
All angles and glass; the Ford GT90 was the first Ford to display the company's “New Edge” design philosophy. The GT90 was built around a honeycomb-section aluminum monocoque and its body panels were moulded from carbon fiber.

Ford GT90 Front
The V12's exhaust was claimed to be hot enough to damage the body panels, requiring ceramic tiles similar to those on the Space Shuttle to keep the car from melting.

Gallium – A Rare Metal with Interesting Properties


Gallium – A Rare Metal with Interesting Properties

Gallium melting in a person's hand
A truly peculiar metal with an ultra low melting point of just 29.76 °C (85.57 °F) and the ability to attack most other metals by diffusing into their metal lattice (greatly weakening their structure).
In 1871, existence of gallium was first predicted by Russian chemist Dmitri Mendeleev, who named it "eka-aluminium" on the basis of its position in his periodic table. He also predicted several properties of the element, which correspond closely to real gallium properties, such as density, melting point, oxide character and bonding in chloride. Gallium was discovered spectroscopically by French chemistPaul Emile Lecoq de Boisbaudran in 1875 by its characteristic spectrum (two violet lines) in an examination of a sphalerite sample.
Gallium melting in a person's hand
Elemental gallium is not found in nature, but it is easily obtained by smelting. Very pure gallium metal has a brilliant silvery color and its solid metal fractures conchoidally like glass. Gallium easily alloys with many metals, and is used in small quantities as a plutonium-gallium alloy in the plutonium cores of nuclear bombs, to help stabilize the plutonium crystal structure.
Today, almost all gallium is used for microelectronics (gadgets like your phone, TV's and even cars). Gallium arsenide, the primary use of gallium, is used in microwave circuitry and infrared applications.
Take a look at the following video and see this metal in action as it destroys an Aluminum soda can. Unreal!
