The Bill Nye demonstrates the functionality of a Stirling engine The Stirling engine is an external combustion heat engine that works with a specific amount of air circulating within a container. The cyclic compression and expansion of air that is in the pot with the help of a plunger converts thermal energy into kinetic. Here, the presenter and scientific researcher Bill Nye makes us a demonstration of the machine.- A miniature Stirling engine A Stirling engine with a 5 mm diameter cylinder. The Stirling engine is an external combustion heat engine that works with a specific amount of air circulating within a container. The cyclic compression and expansion of air that is in the pot with the help of a plunger converts thermal energy into kinetic.
- 1909 fan that works without electricity This fan is 110 years old. Constructed in 1909 by German Hubertus Raab and its operation using a hot air Stirling engine. The Stirling engine is an external combustion heat engine that works with a specific amount of air circulating within a container. The cyclic compression and expansion of air that is in the pot with the help of a plunger converts thermal energy into kinetic.
- An 8-cylinder Stirling engine The Stirling engine is a thermal external combustion engine that operates by compression and expansion of air. With the aid of a plunger, the thermal energy is converted into kinetic. Here we see original Stirling engine with 8 cylinders, which is for sale here.
- He wanted to fill the tea machine (fail) The employee of a restaurant Chick-fil-A in Lilburn Georgia's (USA) He wants to fill the machine's iced tea. Without requesting any help, lifts a large pot containing several litres of tea to the transfer in the tank of the machine. Unfortunately, things will not go as he had planned. Foot of glide and the youngster falls throwing the entire contents of the container on top of. Watching the upheaval of colleague, a woman approaching him to comfort him with a hug.
- Easy placement of food in vacuum The Kenji Lopez, cooking Manager page "Serious Eats", shows us a technique for easy placement of food in vacuum without the use of packaging machine. Using an airtight nylon pouch that is sinking slowly into a basin with cold water leaving a small opening. The air is pushed out from the pouch with the help of water pressure, and then there is the completely closed, taking care that the water does not penetrate inside.
- That won a cycling Sprint; A Eurosport video explains how won a Sprint in a bike race. A sprint takes an average of 13 seconds and the runners run at a speed of about 65 km / h. Important factors to win a sprinting speed, the acceleration, the location and the most important, the teamwork in the final kilometre. During a bike race, It is very important for cyclists to know how to maintain their energy. With the help of team sprinter stays in last place and the others are trying to be ahead to reduce as much as possible the air resistance. When the first will consume 100% of the energy, the fourth will consume only 62%. The ideal is for the sprinter to have his teammates in the top 3 positions to do the job for him. The sprinters will spend all his energy only in the last 300 meters to win the match.
- A small chariot with Stirling engine A Japanese built a small float that moves with the help of two Stirling engine. How does a Stirling engine you can see in this video.
- Vacuum machine The vacuum machine (vacuum engine) is an external combustion engine and works as follows: The flame produced by the container with alcohol is absorbed into the cylinder by a small hole and is trapped with a valve. The air inside the cylinder is now warm and swells, with the result that pushes the piston. After the motion of the piston in the cylinder air cooled, and creates a pressure drop that absorbs piston again. So the valve opens again and repeats the cycle of motion.
- Fan powered by a kerosene lamp A fan made by the Carl Jost company in the 1910s in Zeitz, Germany. This fan is powered by a kerosene lamp and uses a hot air motor to move its blades, instead of relying on electricity.
- Cleaning the icy road with a blower A British man clears the icy road outside his house, using a strong blower. Pieces of ice are easily detached from the road, with the help of pressurized air.
- Automatic machine for soap bubbles An improvised machine that creates soap bubbles. It works with an upside down fan that as it rotates, he dips a ring in soapy water and blows it with the air from its blades.
- A Rube Goldberg machine that makes pizza A Rube Goldberg engine powered by a small electric train, makes a pizza. A video by Joseph Herscher.
- The larger gear array in the world This is perhaps the greatest speed splitter gear you've ever seen. It takes more energy than is observed in the universe, that the last gear to make a full rotation. A creation by artist Daniel De Bruin, inspired by the "Machine with Concrete" of Arthur Ganson. The Daniel De Bruin constructed this camera to demonstrate the vast size of the number googol (googol). In Math, a googol is a natural integer which corresponds to 10 ^ 100 (i.e., one followed by one hundred zeros). A number greater than the amount of people present in the known universe. This mechanism has a bearing assembly, with each gave rotational reduction ratio 1/10. Since there are 100 gears in the mechanism, the first should be rotated 10 ^ 100 times so that it can make a complete rotation. This would require more energy than is available in the observed universe theory (10 ^ 70 joules) - assuming that a full rotation of the first wheel requires 1 Joule.
- How to properly organize your nails Based on intuition, one can think that this is a video that plays In reverse, but this is not the case. When energy is added to the system shaking the bucket, nails begin to act like a liquid, filling the natural shape provided in their container. Since they don't receive enough energy to flee in all directions, frictional forces and weight decrease the energy of the system, bringing it to a lower power state and higher entropy, which is their arrangement within the container.
If you can build it might be fine for the physical test
