The flying car

The car flies .Is it so ? Do you believe? Yes it is real now  and makes people  wonder what it means.It is not just fun but a reality.

Up in the Sky, it is a Plane...But on the Road, it’s a Car, marvelous

This is a new revolution in aeronautical science, the flying  car.Massachusetts-based Terrafugia has created a vehicle called the Transition that can operate both the car and airplane.. This flying car is fueled with standard unleaded gasoline and get transformed from plane to car and back in just a minute.

The company relied on 3D CAD to model the Transition and to make the precise calculations needed to meet both aircraft and road vehicle safety and the  performance standards. The most important thing in it is the use of simulation to reduce the mass. Followings are some videos of test flight. This has been the mile stone in the aeronautical science  as it is a transition between the car and airplane , indeed operate as both.

Geothermal power ,Natural resource of energy-Its benefits comparable to coal price.

The environmental benefits of burning less fossil fuel by using renewable sources of energy—such as geothermal, hydropower, solar and wind—are clear, there's been a serious roadblock in their adoption: cost per kilowatt-hour.

That barrier may be opening, however—at least for one of these sources. Two recent reports, among others, suggest that geothermal may actually be cheaper than every other source, including coal.Geothermal power plant work by pumping hot water from deep beneath Earth's surface, which can either be used to turn steam turbines directly or to heat a second, more volatile liquid such as isobutane (which then turns a steam turbine). The newest report, from international investment bank Credit Suisse, says geothermal power costs 3.6 cents per kilowatt-hour, versus 5.5 cents per kilowatt-hour for coal.See the video below to get the latest geothermal procedure.
