Sean Hodgins (Hodgins Sean) loves building small electronic gadgets. One of them — a ring that turns body heat into light. The ring is made of aluminum — an excellent conductor of heat, which is necessary for the generation of electric energy. To convert heat into electricity is the Peltier module. The Peltier module converts heat that goes from the ring into a small voltage, and the circuit Board amplifies the current. Currently, the efficiency of the device depends on the temperature of the air, but Hodgins is developing a new scheme to make it work at any temperature.
THE ENERGY FROM THE RING
Called hybrid Quadski, from the English “quad – Quad”, and “jetski jet ski”. As the name implies, the main principle is to combine features of both machines. Quadski provides You fast and comfortable transportation by land and water! He will surely manifest itself on any road. The housing is made of impact-resistant plastic, and suspension components and the frame is of forged aluminium. The BMW engine is a 1.3-liter, 4-cylinder, with a capacity of 140 HP Maximum speed – 72 km/h!
I have to say, I don’t homebrew and the car was collected only in order to check how the mechanism of rotation, which I patented. So the car made a simple that have no practical value, except to ride in shallow snow. Caterpillar used Baranovsky, long, sawn her jigsaw into two parts. Stars also buranovskie. As the traction engine took skaterny 150 CC motor with a CVT. Differentials muravievskaya, the rotary electric motor of 1.2 kW from the mixer.
The project is called “IRBIS”, which means snow leopard generated for serial release professional 3-D complex. The complex includes a 3-D printer high resolution and large print area. Automatic 3-D scanner for high-resolution rotary table and the extruder for the production of ABS rod for printing with a diameter of 3 mm.
You built the plane. Naturally the desire of the designer to quickly rise into the air. However, the first thing you must “train” to learn flying on your aircraft are extremely serious and responsible. First of all it’s elaborate and it is good to understand the fundamental principles of flight dynamics, principles of stability and controllability of the aircraft. You need to assess what dynamic features are common to your machine – in particular, what is the stall speed, takeoff and landing and maximum speed, how effective are the rudders, and finally, how stable in the air the unit itself. And only then can you begin the exercises in the cockpit and actually fly, strictly following the principles of gradualism in the development of the machine. Today we open a kind of correspondence summer school for Amateur constructors and pilots. We will introduce you to the basics of flight art the most common mistakes novice pilots, as well as techniques correct behaviour of pilots in extreme situations.
Using the experience of previous generations, lifting them achieve a new level of quality, the development of scientific thought is moving up in a spiral. Not accidentally, the inventors, creating increasingly sophisticated machines, often return to the experience of its predecessors — rely in their search for designs of bygone years.
Developed a rifle that can’t miss. This year at CES, manufacturers have brought not only consumer electronics, but the device is absolutely not related to peaceful applications. The company TrackingPoint presented at the exhibition CES-2014 is a semi-automatic rifle 500 Series AR Smart Rifle, which will hit the target even if shooting for an inexperienced user. The rifle uses a system of intelligent fire control Precision Guided Firearms. Numerous tests and comparisons showed that the accuracy provided by the system Precision Guided Firearms, at least five times greater than the accuracy of an experienced shooter, at least at distances up to 500 meters. The arrow is only necessary to mark a target and start to aim in the required direction, and the weapon itself will do the rest in automatic mode, according to nbcnews.com.
