Death Ray | Teleforce

2020-06-26T10:00:00.042+05:30

A weapon from which comes a out a ray that can destroy anything from a long distance of 200 miles. This weapon was invented by Nikola Tesla in 1937. In 1937, he said that he had invented the 'Death Ray' and he will show the model within few months to the people.

Tesla was experimenting on the wireless electricity transmission. He invented many devices in his life which can transmit electricity wirelessly. In the time of experimenting the wireless energy he also invented the 'Death Ray'. He named his invention as 'Teleforce'. In the time 'Guglielmo Marconi', 'Harry Grindell Matthews', 'Edwin R. Scott', 'Graichen' Also tried to make the 'Death Ray' but they couldn't able to show the model of 'Death Ray' in public.

Tesla said that other's invention of death ray didn't run because to run the device a lots of electricity is needed. But this amount of electricity can't be produced because the whole New York's sum electricity is less than needed to run this device. Tesla's 'Teleforce' machine can destroy in the range of 200 mile.

Tesla Turbine | Boundary Layer Turbine | Flat-disk Turbine | Bladeless Turbine

2020-06-25T01:30:00.000+05:30

Tesla Turbine

The 'Tesla Turbine' also known as 'Boundary Layer Turbine', 'Flat-disk Turbine', 'Bladeless Turbine' was invented by Nikola Tesla in 1913. The Tesla Turbine was one of his great inventions. This turbine has no blades to drag the axel move by the water. It has two disk in which was a very small, very small gap.

The Tesla Turbine has much more efficiency than a water turbine. According to Nikola Tesla, this turbine's efficiency is 60% - 95%. Here, in the Tesla Turbine water and blades are not used as a normal water turbine. It also uses nozzles to flow the fluid. In this turbine the Laminar fluid is used. This turbine runs on the principle of Shear Forces by Boundary Layer flowing fluid on a solid surface.

In this turbine a fluid flows with a high velocity from the nozzles. The Laminar fluid applied to the edge of the disk. The fluid drags the disk by means of viscosity and the adhesion of the surface layer of the fluid. As the fluid slows and adds energy to the disks, it spirals into the center exhaust. The Laminar fluid will make a boundary layer with the disk's surface and make it moving because of Shear Force. The disk is attached with a axel, when the disk rotates by the shear force by boundary layer of fluid, the axel also rotates. The turbine's axel joined with a generator. When the turbine's disk rotates the generator makes energy. We can flow the fluid in any direction, clockwise or anti-clockwise. The power output of the turbine depends on the number of disk used, the spacing of the disk's, the velocity of inlet fluid and the type fluid used.

Differences between a Water Turbine and Tesla Turbine:

Tesla turbines has not blades but water turbines has blades.
The Tesla Turbine uses a Laminar fluid where the water turbine use the water.
Tesla turbine can move in both direction, clockwise and anticlockwise but water turbine can move only in one direction.
Tesla turbine is much more efficient than water turbine.
Tesla turbine is maintenance free but there water turbine has a lot of maintenance.

Some specifications are :

This turbine can move clockwise and anticlockwise both.
The number of disks increase the rpm of the turbine grows.
This turbine is easy to build.
This turbine don't needs maintenance ( it is maintenance free).
It also can be use like a pump.

Plasma Lamp | Tesla Lamp

2020-06-22T23:53:00.000+05:30

Plasma Lamp:

Plasma lamps are a type of electrodeless gas-discharge lamp energized by radio frequency(RF) power. The internal-electrodeless lamp was invented by Nikola Tesla after his experimentation with high-frequency currents in evacuated glass tubes for the purpose of lighting and study of high voltage phenomena. The first practical plasma lamps were the Sulfur Lamps manufactured by Fusion Lighting. This lamp suffered a number of practical problems and did not prosper commercially. Plasma lamps with an internal phosphor coating are called External Electrode Fluorescent Lamps(EEFL); These external electrodes or terminal conductors provide the radio frequency electric field.

If you've ever touched a plasma ball when it's on, you know that placing your finger on the glass draws a colorful strand of light to your finger. It's like creating your own personal bolt of lighting from the electrode to your finger!

The phenomenon occurs because of the conductive properties of the human body. When you touch the glass, you create a discharge path with less resistance than the surrounding glass.

At first let's know what is Plasma?

What is Plasma?

Although it sounds a bit mysterious, plasma is actually the most common form of matter in the universe. Plasma is simply the fourth state of matter that's different from solids, liquids, and gases. The Southwest Research Institute defines plasma as "a hot ionizes gas containing roughly equal quantities of positively charged electrons".

Plasma Ball:

A Plasma Ball- also sometime called as 'Plasma Globe', "Plasma Dome" or "Plasma Sphere" is a clear glass sphere filled with various gases like Neon sometimes with other noble gases such as Argon, Xenon and Krypton at nearly atmospheric pressure and with a high-voltage electrode at it's center. A crackle tube is a related device filled with phosphor coated beads.

The plasma lamps are driven by high frequency (approximately 35KHz) alternating current at 2-5 kV. Plasma filaments extend from the electrode to the glass when electricity is supplied, creating fascinating beams of color light.

History:

In February 6, 1894, Nikola Tesla describes a plasma lamp. This patent is for one of this first high-intensity discharge lamps. Tesla used an incandescent-type lamp globe with a single internal conductive element and excited the element with high voltage currents from a Tesla Coil, thus creating the brush discharge emanation. He gained patent protection on a particular form of the lamp in which a light-giving small body or button of refractory material is supported by a conductor entering a very highly exhausted globe or receiver. Tesla called this invention "The Single Terminal lamp", or, later, the "Inert Gas Discharge Tube".

Tesla Tower | Wardenclyffe Tower

2020-06-20T14:42:00.004+05:30

Tesla Tower or Wardenclyffe Tower:

Wardenclyffe Tower(1901-1917), also known as the Tesla Tower, was an early experimental transmission station designed and build by Nikola Tesla in Shoreham, New York in 1901-1902.

The tower went 187 feet(57 m) up into the sky. The base was framed with wood, but the giant ball on the top, 68 feet in diameter, was made of steel. In the ground below, there were said to be tunnels and an "iron root system" that went deep into Earth. Nikola Tesla, the inventor and engineer who helped electrify America, believed the tower was the start of a system that could deliver electricity, without wires to the whole world.

Nikola Tesla

At the beginning of the 20th century, Tesla had become famous for his work on AC power. But he had other big ideas. At his laboratory in Colorado, he had conducted experiments with wireless transmission, typing to send electricity through the ground. His notes on this work are hard to draw conclusion form. But it seems that in the last one instance he had some success. At the very least, he come back east convinced that he could make this idea a reality, on a much larger scale.

Construction started: 1901

Height: 57m

Opened: 1901

Location: Shoreham, Long Island, New York

Architect: Nikola Tesla

Added to NRHP: July 27, 2018

After shopping his idea to the some of the richest men in the world, Tesla secured backing - a solid $150,000 - from J.P. Morgan. The investor was most interested in the idea of wireless communication (as Guglielmo Marconi, an Italian inventor, had recently been demonstrating his system for wireless telegraphy, sending message from ships to back to land) but Tesla had bigger ideas.

Stanford White

In an attempt to satisfy Tesla's debts, the tower was demolished for scrap in 1917 and the property taken in foreclosure in 1922. For 50 years, Wardenclyffe was a processing facility producing photography supplies. Many buildings were added to the site and the land it occupies has been trimmed down to 16 acres(6.5 ha) but the original, 94 by 94 ft.(29 by 29 m), brick building designed by Stanford White remains standing to this day.

In the 1980s and 2000s, hazardous waste from the photographic era was cleaned up, and the site was sold and cleared for new development. A grassroots campaign to save the site succeeded in purchasing the property in 2003, with plans to build a future museum dedicated to Nikola Tesla in 2008 the property was listed the National Register of Historic Places.

Octopus have three hearts, nine brains and blue blood

2020-06-18T15:18:00.001+05:30

Octopus have some interesting facts that you may don't know. The facts are

1. Octopus have three hearts and blue blood:

Octopus have three hearts. Two of the hearts work exclusively to move blood beyond the animal's gills, while the third keeps circulation flowing for the organs. When the Octopus swims, the organ heart stops beating, which explains why these prefer to crawl rather than swim( it exhausts them).

Unlike vertebrates that have iron-rich hemoglobin packed into red blood cells, Octopuses - along with some tarantulas, scorpions and horseshoe crabs- have copper -rich hemocyanin dissolved directly in their blood (this means their blood is blue).

Hemocyanin is less efficient than hemoglobin as an oxygen transporter. The three hearts help to compensate for this by pumping blood at higher pressure around the body to supply the Octopus's active lifestyle.

2. Octopus have nine brains:

The Octopuses have nine brains. A central brain controls the nervous system. In addition, there is a small brain in each of their eight arms -- a cluster of nerve cells that biologists say control movement. This allows the arms to work independently of each other, yet together toward the same goal.

He Octopus has the highest brain to body mass ratio of all invertebrates; it is also greater than that many vertebrates. It has a highly complex nervous system, only part of which is localised in it's brain, which is contained in a cartilaginous capsule. Two-thirds of an Octopus's neurons are found in the nerve cords of its arms.

Antigravity Helium

2020-06-11T22:25:00.001+05:30

We all know the first noble gas is Helium. We know Helium as a gas for blowing up balloons. but most people don't know about the odd property oh Helium. Helium has two distinct states-one of which is borderline creepy. Helium turns into liquid at about 4.2 Kelvin(-268.95 degrees Celsius). But when is cooled further to below approximately 2 Kelvin, it can do things that other fluids can't, like dribble through molecule-thin cracks, climb up and over the sides of a dish and get motionless when it's container is spun. Now it no longer a mere liquid, it is the superfluid. It can flow without friction. Liquid Helium has been used as a cryogenic refrigerant, and in superconducting magnets such as those used in magnetic resonance imaging(MRI), nuclear magnetic resonance(NMR), Magnetoencephalography(EMG) and some experiments in physics.

Fireproof coatings made from DNA

2020-06-09T21:07:00.002+05:30

In addition to building organisms DNA could also keep your favorite things safe from burning.

Normally, cotton fabrics are highly flammable but when scientists tried to set fire to cotton with the coating of herring sperm DNA, the cotton didn't burnt.

In lab it is tested by scientists that the macromolecule could stop fires by using DNA extracted from herring sperm. Scientists dissolved the DNA in water, coated cotton fabrics with it, let them dry, and tried to light them up. The coating behaved similarly to ammonium polyphosphate, a flame retardant, commonly used to polymeric materials such as polyurethanes(found in foams and Spandex) and polyolefins(found in flexible foams and electrical insulation). It is also a natural retardant.

What human hair have electrons?

2020-06-08T21:23:00.003+05:30

What! Human hair have electros?

Ans: Not really. Human hair haven't electrons until they are rubbed by something. As an example if you rubs your hair with a comb your hair will get some charges. But the nature of charge depends on with thing with you rubbing. By rubbing a type of charge gets the comb and a type of charge hair will get. In winter it often seen.

How much time we can live without eating them?

2020-06-08T20:11:00.000+05:30

We all eats food and water daily. At least 60% of an adult is made by water. But do you know how much time we can live without eating them?

Answer is: A person can live about a month without food, but only about a week without water. If a human does not absorb enough water dehydration is the result.

20% Oxygen of Earth comes from the Amazon Rainforest

2020-06-08T14:43:00.001+05:30

Our atmosphere is made up of roughly 78% Nitrogen and 21% Oxygen with various other gases present in small amounts. The vast majority of living organisms on Earth need Oxygen to survive, converting it into Carbon dioxide as they breathe. Thankfully, plants continually replenish our planet's Oxygen levels through photosynthesis. During this process, Carbon dioxide and water are converted into energy, releasing Oxygen as a by-product. Converting 5.5 million square kilometres(2.1 million square miles), the Amazon Rainforest cycles a significant proportion of the Earth's Oxygen, absorbing large quantities of Carbon dioxide at the same time.

Water can boil and freeze at the same time

2020-06-07T23:06:00.005+05:30

Seriously, it's called the 'triple point', and it occurs when the temperature and pressure is just right for the three phases (gas, liquid, and solid) of a substance to coexist in thermodynamic equilibrium.

Some metals are so reactive that they explode with the contact of water

2020-06-07T11:38:00.001+05:30

There are certain metals – including potassium, sodium, lithium, rubidium and caesium – that are so reactive that they oxidise (or tarnish) instantly when exposed to air. They can even produce explosions when dropped in water! All elements strive to be chemically stable – in other words, to have a full outer electron shell. To achieve this, metals tend to shed electrons. The alkali metals have only one electron on their outer shell, making them ultra-keen to pass on this unwanted passenger to another element via bonding. As a result they form compounds with other elements so readily that they don’t exist independently in nature.
