Amazing Engineering : Making of The World’s Smallest V12 Engine

World’s smallest engine made by a Spanish engineer named Patelo. Who made a history to make the smallest engine ever. He had spent around 1200 hours in designing, milling, turning and drilling to create the World’s smallest engine. He used hunks of aluminum, bronze and stainless steel to create it. In the World’s Smallest engine features 12 cylinders, compressed air injection (0.1kg/sqcm), total displacement of 12 cubic centimeters from its twelve 11.3 mm diameter pistons.

It is totally a charming and cutest, smallest engine ever. Patelo has no plans to sell the mini motor. He presented the World’s smallest engine to his “GRANDCHILDREN”. Really the hard work has give him the real success. There are 261 pieces of the engine made by Mr.Patelo, and used 222 screws which he purcahsed to draw the line. It contains 12 mini pistons with air injection.

Aqua Star AS2 Electric Sea Scooter Equips You for Added Adventures Under Water

AquaStar scooters in Florida have developed a pair of recreational submersibles which both offer ease of use and relative affordability when compared with other undersea vessels.

The two-person AquaStar2 AS2 is based on the smaller, single seat Aquastar1 AS1. Both subs share a similar design, but the AS2 has an additional seat and an extended helmet.

The AS2 offers scuba diving-like capabilities, but without certification, no cumbersome attached gear, and no experience required - especially if you're the passenger.

The AquaStar2 AS2 can dive to around 12 meters (40 ft), and achieve a top speed of 3.1 mph (5 km/h). The batteries last around 2 hours, although the air supply will need changing after 1 hour and 10 minutes. If for any reason the electrical system should fail, a backup system - using the compressed air tank - can bring the sub to the surface quickly and safely.

The easy to use handlebars offer control over direction, depth, and speed.

Because the AquaStar AS2 is an open submersible, the pilot and/or passenger can leave the sub, swim around freely to investigate things more closely, and then return to the vehicle for more air.

AquaStar are marketing their scooters mainly at the tourist and resort markets. Although they could be just as easily operated as a personally-owned luxury toy.
