NANO-FALCON

The tiny helicopter has been named Nano-Falcon and measures just 65mm in length while weighing a mere 11 grams. Apparently, the Nano-Falcon has already obtained the official Guinness world record for being the smallest in its category, but that won’t stop it being a lot of fun to play with.

For around $46 you get a helicopter that can happily rest in a dessert spoon. That 11 grams of total weight somehow includes a rechargeable battery that is good for 5 minutes of flying time after a 30 minute charge (the remote control uses 4 AA batteries). It also looks as though recharging is done via a USB port.

Scientists have built the world's smallest petrol engine in the world which is 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. 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.

LG has releases a new Wireless Charging Pad (WCP-300), which is just 6.98 cm in diameter. LG claims that it is the world’s smallest wireless charger. Even though it is small in size, it would would offer better charging efficiency than the existing wireless chargers with up to 1.7 times large area with its circular design.The WCP-300 employs electromagnetic induction technology and is Qi certified by the Wireless Power Consortium. Electromagnetic induction produces a magnetic field that in turn generates an electric current to charge the batteries in devices placed on the charging pad.
