The World’s Smallest Helicopter - GEN H-4

GEN H-4 is the world's smallest co-axial helicopter ever made.This is a Japanese designed and manufactured ultralight one-man helicopter. The total empty weight of this helicopter is only 155 lbs. Smallest helicopter in the world has two rotors turning in opposite directions to maintain stability, and four engines that enables a 30-minute flight with a top speed of about 56 miles per hour.

Yes, you're right it is a quite interesting contraption! It is true that there is not much to see on the outside. The frame is 2 inch aluminum pipe bent and welded, with a fiberglass backpack and funny looking wheels. The controls are direct, like many gyrocopters. In front of the pilot attached to the control bar is the control panel with the throttle (altitude control), tachometer, ignition power, starter and yaw switches. The tools necessary for flight do not seem like much because they aren't. This is not only the lightest helicopter in the world, but it is the easiest to fly!

Sark Island - Smallest Channel island Photos

Sark is the smallest of the four main Channel Islands. It lies in the English Channel, about 128km from England and about 32 km from the coast of Normandy. There are no cars on the island, and transport other than on foot consists of horse-drawn carriages, tractors and bicycles. The island is formed of steep, rocky cliffs, averaging about 90 m above sea level, rising to a center plateau. At its highest point a windmill can be found, dated 1571. In order to reach this plateau, passengers disembarking in the miniscule harbour must travel upwards through a rock-hewn tunnel made in 1866.

Greater Sark is connected to Little Sark by a narrow, paved isthmus known as La Coupee. Just 2.7 m wide, it has dizzying 90 m drops to either side. Although privately owned, its gardens, some of the finest in the Channel Islands, are open to the public.

This is delightful island, with gorgeous sandy beaches and coves around the coast, ensuring shelter from winds of any direction. There are woods filled with springtime bluebells, and over 600 different plants and wildflowers grow there. Seabirds nest on the cliffs, and birds of prey, songbirds and migrants enjoy its unspoiled landscape.

The World's Smallest Snowman

You're looking at the tiniest snowman ever built. Well, it looks like a snowman, but this minuscule model about a fifth the width of a human hair is not made out of snow. It's constructed of two tiny tin beads that are usually used to calibrate an electron microscope, and welded together with platinum.

It's built by David Cox, a nanotech expert at the Quantum Detection Group of Britain's National Physical Laboratory. He's accustomed to working with such astonishingly small objects, and used his nano-particle manipulation tools to demonstrate the astonishing accuracy of his work.

He bathed the snowman in blue light to give us this entertaining, snow-blown image. The remarkable flourish of his smiling snowman is its little happy face, carved into the top orb using a focused ion beam. That's no small feat.
