sit on top kayak

i know a lot of people like to kayak, there is a lot type of kayak, one of the type is sit on top, which i love to use most. Why most of people like sit on top kayak? here i bring some info to share with:

Fiberglass, paddle floats, navigation maps, self-rescue…you'd like to enjoy the water in a kayak, but perhaps you aren't feeling ready for the investment of time and money it takes to get into the sport. There are lots of alternatives out there for new and recreational paddlers, one of which is a sit-on-top kayak.

Sit-on-tops have similar hull shapes to their traditional counterparts, but instead of sitting inside the kayak, you sit in a molded-in depression on top. Some are fiberglass, but most are made from tough, inexpensive, roto-molded plastic. Sit-on-tops share many benefits with traditional sit-insides, but often are easier to use and less expensive. There are sit-on-tops for fishing, surfing, touring, scuba diving and more. Some of these are considered specialty boats, but most sit-on-tops are built for multi-purposes and with recreational or beginning paddlers in mind.

Sit-on-tops have a few advantages over sit-insides, one of which is comfort. Paddlers with large body types, long legs, or limited flexibility feel less confined paddling a sit-on-top. One of the biggest benefits, though, is the self-rescue. Because sit-on-tops have an open deck rather than an enclosed one, there is no risk of being trapped in the boat if it tips over-no need to practice rolls or wet exits. That really appeals to new paddlers, and people who don't plan to take their kayaks out on expeditions.

as i know for the safety reason, sit on top kayak are the best kayak for you to make activities at the open sea.

The facts you need to know about BMW's New Tron-Like Turbodiesel Hybrid Concept

Here my thoughts about BMW New tron-like turbodiesel Hybrid concept:

The fact you need to know about BMW Hybrid Sports Car

here my thoughts about BMW hybrid sport car:

This is a hybrid sports car that will hopefully hit the market in 2013 and it is unlike anything else on the market. Having access to 356-horsepower and 4.8 second 0-60 speed has speed freaks sitting up and taking notice that there may actually be a car out there that is both economical and fast.

The 63 mpg tag that it boasts is absolutely unreal in terms of conservation. The combination of electric and diesel offers mileage that is up there with pure electric cars. The difference here is of course the design. This car looks like it belongs on the race track instead of the local BWM showroom floor. The big question is whether it will ever come to fruition or not.

Just how committed is BMW to producing a car such as this and how much will it cost? According to a variety of sources, BMW expects to make up to 10,000 units, but a price tag has yet to be determined. Based on their ActiveHybrid 7, figure that it will cost well over $100,000 for the right to sit in the driver’s seat of this machine.

While it is great to see a company like BMW put a product like this on the market, it is even more exciting to see the image of the dull and goofy looking hybrid shattered. Most hybrid and electric cars are hardly aerodynamic or built to be aesthetically pleasing. This new BMW hybrid sports car release shows that we can have the best of both worlds. It will truly bring in a new era of hybrid and electric car design.

If the car is released as expected and meets with success, it will surely open up a whole new niche. Up until now, the high end electric sports car has been a market that few companies are willing to take a chance. For some reason, it is as though auto makers think that just because we like to go fast, we could care less how much fuel we are burning in the process. Now there will be an opportunity to tear up the roads and keep some cash in our pockets.

The facts you need to know about reviews the 2011 BMW ActiveHybrid7

here my thought of 2011 BMW active Hybrid 7:

BMW has trumped its rivals in the hybrid-car business by using a lithium-ion battery pack, which has a higher energy density than the commonly used nickel-metal-hydride type. Higher energy density means more charge for the buck in a smaller package, which BMW, in this case, has cleverly located in the northwest corner of the ActiveHybrid7's trunk.

The battery energizes an electric motor (15-kilowatt, 20 horsepower equivalent) that works in tandem with a 4.4-liter twin-turbocharged V-8 engine (455 horsepower, 515 foot-pounds of torque).

The arrangement saves fuel and reduces tailpipe pollution in city traffic when the gasoline motor shuts down at stoplights and other traffic interruptions and the battery and electric motor take over.

But the two power systems work together on the highway, providing a tremendous boost in acceleration, beating the heck out of many full-size gas-guzzling sedans and wearing something of an environmental halo in the process.

With it all comes BMW 7-Series comfort, elegance and opulence -- four-zone climate control, a leather-wrapped steering wheel with plush leather seats, rich wood-grain accents, ambient interior lighting for night driving, onboard navigation with a high-definition backup camera, and myriad active and passive safety technologies.

The fact of The first Sports Activity Coupé with a hybrid engine: the BMW ActiveHybrid X6.

here is my thought about BMW hybrid engine:

In 2005, when BMW joined General Motors and DaimlerChrysler in a collaboration to develop hybrid technology, it seemed like a strange partnership. The two American companies were working on hybrids for heavyweights—a technology that could provide better fuel efficiency on three-ton full-size SUVs designed to carry seven or eight passengers, extra cargo, and tons of extra weight towed in back.

BMW’s Burkhard Göschel promised, “The technologies will be adapted to the individual vehicle models.” He said, “The participating brands will retain their distinctive characters.” The BMW Concept X6 ActiveHybrid, unveiled at the 2007 Frankfurt auto show, gives shape to the company’s distinctive interpretation of the full-hybrid technology.

The BMW X6 is a cross-over SUV that has crossed over into sports car territory. The company calls the vehicle a “sport activity coupe.” Its chief characteristics are a sleek profile, sloping roof line, low-slung stance, short front overhang, long rear overhang, long wheelbase, muscular wheel arches, large wheels, four-wheel drive, stability control, and lots of performance. The X6 will probably get the 350-horsepower 4.8-liter V8 engine currently supplied in the X5. There’s no SUV pretense that the X6 will be taken off-road.

The two-mode full hybrid—which appears in American form as the Chevy Tahoe and GMC Yukon, and the discontinued hemi-powered Chrysler Aspen and Dodge Durango—has been BMW-ized in the X6 hybrid. The two-mode’s motors, batteries, gearsets and sophisticated software add up to a 20 percent fuel efficiency improvement over the conventional X6.

When we spoke with Tom Purves, chairman and CEO for BMW of North America, at the Detroit Auto Show, he said “A BMW customer may not be desperately worried about paying his gasoline bill. But he would like to have bragging rights that his new 7 series doesn't just go fast, it actually uses a bit less fuel." The BMW X6 ActiveHybrid is another example of how the company is keeping its focus on luxury and performance, while integrating slow steady fuel efficiency improvements which, by the way, come with the package. It’s a BMW first, and a hybrid second.

Breathtaking sports car performance combined with the savings potential offered by the latest in hybrid technology. The BMW ActiveHybrid X6 is designed for everyday use, delivers outstanding performance in every driving situation and can be operated fully electrically. This is BMW ActiveHybrid, an additional pillar of BMW EfficientDynamics.
The key to increased efficiency at all speeds lies in the perfect interaction of combustion engine and Two-Mode Active Transmission with two powerful electric motors. The BMW ActiveHybrid X6 can be driven electrically and silently up to a speed of 65 km/h. The boost function supplies additional power when overtaking when the electric motors lend short-term support to the BMW TwinPower Turbo V8. They also charge the high-performance battery during every braking manoeuvre.
The BMW ActiveHybrid X6 combines the sporting appearance of a Sports Activity Coupé with distinctive and aerodynamic finesse. Exclusive BMW ActiveHybrid characteristics include model logos on the front doors and boot as well as the 20-inch Aero wheels Streamline. When seen from the front and rear, the horizontal lines and prominent wheel arches emphasise the vehicle's power, breadth and presence. The side view shows the elegant coupé proportions while the roofline flows down to the rear end cutoff in a gentle curve. Two character lines underscore the dynamic wedge shape.
