Worlds Smallest Petrol Engine

Scientists have created the smallest petrol engine in the world(less than a centimeter long not even half an inch),small enough to power a watch or any small gadget.The mini-motor, which runs for two years on a single squirt of lighter fuel, is set to revolutionize world technology. 

It generates 700 times more energy than a conventional battery. It could be used to operate laptops and mobile phones for months doing away with the need for charging. 

Experts believe it could be phasing out batteries in such items within just six years. The engine, minute enough to be balanced on a fingertip, has been produced by engineers at the University of Birmingham.

At present, charging an ordinary battery to deliver one unit of energy involves putting 2,000 units into it. The little engine, because energy is produced locally, is far more effective. One of the main problems faced by engineers who have tried to produce micro motors in the past has been the levels of heat produced. 

The engines got so hot they burned themselves out and could not be re-used. The Birmingham team overcame this by using heat-resistant materials such as ceramic and silicon carbide.

Wind Lantern!

In this project, we’ll build a small, vertical-axis wind turbine, or VAWT for short. These are not as efficient as their horizontal-axis cousins, but they are better suited to urban environments where wind can come from all different directions.

Normally, when you give electricity to a motor, it spins. The same is true in reverse: If you give a motor a spin, it acts as a generator and creates electricity. The wind lantern will use energy from the wind to turn a motor and the resulting energy to light up some light emitting diodes (LEDs) within the base. The wind lantern will use this electricity to create a flickering, glowing indicator of the wind.

Solar Powered Stadium

Taiwan's dragon-shaped arena is the perfect example of the scalability of solar power. Designed by Toyo Ito, this 50,000 seat area generates 100% of its electricity from photovoltaic technology through its 8,844 solar panels that illuminate the track and field with 3,300 lux.

Solar Powered Plane

The sky's the limit with solar power. Literally. As wide as a jumbo jet and the weight of a mid-sized car, the Solar Impulse plane, composed of 12,000 solar panels, can fly day and night. It's currently undergoing test flights, but it's working towards a record-breaking round-the-world journey.

Coolest Uses Of Solar Panels

This is so smart: Proposed bus stop would gather solar energy, convert it to electricity and then transfer to electric buses.

so what are your views about this idea???

Proposed bus stop would gather solar energy, convert it to electricity and then transfer this to electric buses, allowing them to always be charged.

Although individual consumers may be reluctant to trade in their gas guzzlers for electric vehicles, public transit departments have already been experimenting with these low-emission alternatives. But the challenges of electric transportation are the same for municipalities: mainly, how do you keep the vehicles fully charged without constant interruptions to the travel schedule?

The ATC Solar Curve Bus Stop concept by Studio Mango, featured recently on Design Buzz, could be an answer to this conundrum. Designed for integration with existing bus stops in the Dutch city of Noord-Brabant, the Solar Curve would place inductive charging technology into bus stops that would allow electric buses to recharge their batteries every time they stop to pick up passengers.

Inductive charging uses an electromagnetic field to transfer energy between two objects. Energy is sent through inductive coupling to an electrical device, which then can use that energy to charge its batteries.

Approximately 15.5 meters of solar panels installed on top of the structure’s roof would collect and convert sunlight into electricity throughout the day. The roof would be curved in such a way that would both protect waiting passengers from the elements and allow the energy to be transferred to the bus wirelessly anytime the vehicle pulls up underneath the overhang.

Components for inductive charging are hidden and protected against damage or dirt in the Solar Curve’s tilting roof construction. Green LED lights on the bus stop/charging station that can be read very easily by the bus driver as well as the waiting public would indicate when the bus is ready to hit the streets again.
