How Tech Helps Racing Yachts Sail Faster Than The Wind

Are you the ones mesmerized by the wind-speed of the racing yachts of America’s Cup? Then, you are not alone! The speed of these yachts that beat the speed of the wind never fails to impress everyone but, at the same time, it isn’t magical as you think! No, the enormous energy here wasn’t produced magically to defy the second law of Newton, as all that has been done here is only harnessing more than one form of wind, as stated by Steve Collie, the aerodynamic engineer for New Zealand’s Emirates Team! Or, in other words, these yachts rely on the better means of the technology that has helped all such racing boats to sail faster than the wind, impressively!

  • Solid wing

Instead of a billowing sail, the racing yachts, these days, come with a solid wing that improves the speed of the yachts, sometimes, even dangerously, as they are capable of ‘catching’ huge amounts of the wind! This solid wing is usually made up of the carbon fiber material, and the size of it is similar to the wing size of the Boeing 747 airplanes!

  • Hydrofoiling

To improve the speed of the yachts, the concept of foiling plays the major part! In order to improve the foiling part, there has to be the decreased effect of dragging that results in 10-15 percent increase in the speed! It is what these hydrofoils of the racing yachts do, where, the wing-like foils that are mounted beneath the hull, pushes the hull up and out of the water, as soon as the yacht increases the speed to minimize the wetting that results in decreased dragging and improved speed that is even capable of defying the speed of the wind!

So, it isn’t magic but, physics and technology that define the wind-speed of these racing yachts and to buy one of this kind or more visit 4yacht.com!

3 Things To Know About High-Dynamic Range Rendering

Virtual reality is what has the market today. Everywhere you turn, you are sure to see one or two virtual reality gaming centers or VR headsets, etc. technology has improved to such an extent that people can experience this virtual reality even in their homes, by just using their phones and the specific VR headsets for them.

HDR – High Dynamic Range rendering is what makes this VR possible. HDR increases the realistic feel of the images and the videos, as a result, the user is immersed more into this virtual world before he loses himself to it and forgets the real world. After the game is done, the player is left with such an experience that is bound to stay fresh in his mind for quite some time.

Here are 3 important things one must know about HDR if they are planning to use this in their profession:

  1. Lighting is extremely important. As long as the light sources used are good and close to real-time lighting, the output will be more realistic. I used a melbourne 3d company and my project video looks like it has been shot in real time. This is because they paid attention to the color space and adjusted the light sources accordingly.
  2. The natural environment has a number of textures and materials and these have to be incorporated into the 3D render as well. If the render is free of such textures or materials, one can easily make out the graphics involved, thus reducing the effectiveness of the 3D rendering.
  3. Checking you final 3D images against a number of state of the art tone mapping operators will help you achieve a result that is very close to reality. The more realistic it looks, the more successful your output it. Tone mapping operators help in retaining the perceptual reality of the human visual system, thus making it more realistic.

How Magnetic Systems are being used in Flash Lights

There is a misconception in the masses that flashlights require batteries to function. Hence, those who are energy conscious choose models which run on rechargeable batteries. But did you know the flashlight can run without batteries too and at an equally optimum level?

How can magnets run flashlights?

In 1830, Michael Faraday, a scientist discovered that when a magnet is passed through a coil an electrical current is induced. Based on this theory flashlights have been created which can be switched on by just shaking them.

How can magnets power the flashlights?

What happens when you shake a flashlight is that a magnet passes back and forth through a coil of wire and induces an electromotive force or an EMF which powers on the flashlight. The force created by shaking is stored in a capacitor in the flashlight and this release the energy when the device is switched on.

How can you use them?

You must shake these flashlights vigorously for three minutes at least for a full charge or a minimum of 30 seconds if the battery is not fully discharged. Once you switch on it will work till the charge diminishes and then you can repeat the shaking to charge it again.

These flashlights usually use LED bulbs which require less power.

Pros and Cons

These flashlights are hardy and can withstand abuse. They are environmentally safe. They are ideal for emergency situations where you won’t be let down by a battery out of charge.  The only disadvantage with these lights is that they use very strong magnets which must be kept away from watches, credit cards, and other magnetic materials.

If you are ever asked ‘Are tactile flashlights safe?’ or ‘Are these flashlights safe?’ the answer to both the questions will be the same – they are same but are suited for different purposes. Tactile flashlights are ideal for military use while these flashlights are better suited for hardy life in the outdoors.…

The most cool 3D high tech printing methods

3D printing techniques have eventually become the most noticeable and remake industry of the era. Due to its range and potential, 3D printers are used in various industries including fashion, food, aeronautics, medicine, construction and device manufacturing. 3D printers are changing the general phenomenon of how things are made. It is expected that 3D printers will grow around 500 percent in coming 5 years.

With its growing impact, it is important to know about the various 3D techniques. One must consider his budget and scope of use before choosing it.

  1. Fused Filament Fabrication (FFF): This 3D printing technique uses strands of molten plastic thread and extrude it to build a shape. The working of this 3D printer is as similar as a spider weaves its web. This 3D technology is relatively easy to use.

The raw material, plastic filament, is cheap and affordable. Available under a price of $300, these are entry level and standard printers.

Though the cheap raw material leads to low-quality parts yet the parts are more accurately designed as compared to expensive methods.

 

Pros:

  • You get accurate colors.

Cons:

  • The production speed and surface finish are sacrificed when compared with expensive models.
  1. Stereo lithography (SLA): This 3D technology constructs objects layer by layer. It traces out the thin pattern of resin and zaps it with ultraviolet rays to harden it. The process is repeated layer by layer until the final product is formed. As each layer binds the other one, the final product that comes out is much stronger and sturdier.

If you are seeking an artwork or any professional model, dental or medical device, SLA technique is ideal.

Pros:

  • The strength of the 3D model is incomparable to any other model.
  • It works much better that $500 3D printer.

Cons:

  • Due to constructing each layer, the final cost of the product is too high.
