What is the most interesting vehicle, land sea or air, you know about?
Ever fancied an off-road vehicle that can transform into a boat in less than 15 seconds? And now you can actually buy one, as amphibious vehicle manufacturer WaterCar presents the Panther--a Jeep based off-roader that can swim.The Panther is a commercial amphibious car manufactured by California-based WaterCar. It was introduced in 2013 after 14 years of development by founder Dave March. It is currently being produced in Fountain Valley, California. It is considered the fastest amphibious car in the world and is equipped with a hydraulic off-road suspension which retracts the wheels in under eight seconds.The framework of the car consists of a hull and chromoly chassis epoxied together. The chassis, which resembles a sand rail dragster, resists impacts on land and water. The non-corrosive fiberglass body makes the Panther stronger than most boats and durable on the street. The fiberglass hull is stuffed with US Coast Guard-approved Styrofoam to aid buoyancy (it's reportedly 'unsinkable') and the patented transfer case allows power to be shifted from the engine to the propulsion jet and transmission.FeaturesThe Panther reaches water speeds of 45mph - as fast as a speedboatIt can be driven straight from the land into water The amphibious design goes from a car to a boat in just 15 secondsChromoly chassis of the carThe Panther design is solely based on the Jeep compact SUV. THE PANTHER'S SPECIFICATIONSWeight: 2950 lbsHeight: 69" windshield up, 51" windshield down, 44" windshield down, wheels retractedLength: 180"Width: 72"Water Speed: 44 mphLand Speed: 80+ mphPassengers: 4Engine: Honda 3.7 liter VTECTransmission: 4 speed manualMarine Propulsion: Panther JetBrakes: Four wheel discWheel Retraction: HydraulicFuel: 91 Octane Pump GasCooling System: Closed with marine heatWater way to drive!

Design For A Non-CO2 Dragster?
Change the engine mount design and use an Estes model rocket engine.
What happens to the kinetic energy of the car, when it is stopped by applying brakes?
A moving car has a lot of kinetic energy. When you apply the brakes, that energy of motion is transformed into something else, and the car slows down.Most cars use friction brakes, which inhibit motion by converting kinetic energy to heat. Because cars are massive and move fast, they have a lot of energy to convert. That means brakes get very hot, 450[math]^\circ[/math]C or more during typical use.As brakes heat, they fade (become weaker) and eventually fail (that's why it's good to shift into a lower gear on a long downhill grade rather than ride the brakes). During extreme use, brakes can even catch on fire:More advanced automobiles use regenerative braking, where a portion of the kinetic energy is converted to electrical energy and stored in batteries (this is not 100% efficient and a significant fraction of the kinetic energy is still converted to heat). Regenerative braking adds cost and complexity to the design, but also adds a lot of efficiency (it's one reason a Prius gets > 50 mpg) and extends the life of the braking system.
