Transcript of Hendo Hoverboard
“If you can levitate a train, why not a building?” - Greg Henderson
3 basic components are used in the construction of a Hendo Hoverboard, and they are:
1. A Copper platform below the board. Looks like:
2. An Aluminum body. Looks like:
3. Electromagnets composed of iron wrapped in Copper coils inside the four "Hover Engines." Looks like:
Hover Engine containing electromagnet
Body of the board
Energy Transfers of the Hoverboard:
Potential Chemical Energy
Vertical motion upwards Thermal Energy
The hoverboard is powered by a battery that stores chemical energy
Created by: Benny Mirisola
Once the board has been turned on, the potential chemical energy is transformed into electrical energy. This creates an electromagnetic field, which is induced onto the platform below it.
No longer part of the energy transfer system.
Potential chemical energy is mostly transformed into thermal energy, or heat, which is then cooled down by fans inside the Hover engines.
The electromagnetic field that has been induced onto the copper platform below creates a varying field that is exerted from the copper platform, and will always be oppositely charged from the electromagnets above it. This causes the magnets to repel, and for the hoverboard to lift off the ground.
3 forces act on the Hendo Hoverboard as it operates, and they are:
Created from the varying electromagnetic field that is continuously switching poles.
By continuously switching the poles, and making the copper platform contain an equally charged pole, the board is lifted off the ground.
The Hendo Hoverboard is lifted into the air by the electromagnetic force that is created by the varying electromagnetic field.
After being lifted into the air, the Hendo Hoverboard stops after a whopping 1 inch of levitation.
According to Newton's 1st Law of motion, an object in motion will stay in motion unless acted upon by another force, meaning another force must be countering its levitation.
As the board moves higher and higher, the electromagnetic repulsion gets weaker and weaker. Eventually the pull of gravity becomes equal to the electromagnetic force, causing it to suspend its vertical motion upwards.
The pull of gravity becomes equal to the repulsion force, causing the board to stop.
As the rider pushes the board, they are transferring their potenitial chemical energy into kinetic energy, causing motion. However the board will eventually stop.
Once again an outside force is acting on the rider and board, and this time it's drag.
As the rider gracefully glides around on their board, the force of drag is resisting their motion, causing the motion force to be lessened, and the board to halt.
As the rider pushes the board, the air resists their motion, stopping the board in place.
2 motions occur when the device operates
Vertical motion occurs when the device is turned on, and the varying electromagnetic field induces an opposing magnetic field into the copper below.
Since the poles are sames the copper and hover engines repel, causing it to lift off the ground, or preform a vertical motion upwards.
When the device is turned off, it preforms a vertical motion downwards.
Vertical motion upwards when on.
Vertical motion downwards when off.
The rider controls the horizontal motion
According to Newton's 3rd Law, every action has an equal, but opposite reaction.
This means if the rider pushes, the board from the opposite direction of where they want to go, the board will move horizontally towards the desired direction.
A push this way, causes the board
to move this way:
A push this way, causes the board
to move this way:
The idea of a hoverboard was first mentioned in the movie "Back To The Future II." (The movie ironically took place in the year 2015!)
The repulsion technology of the board came from the Maglev Train design, in which magnets used to levitate and pull the train forwards and backwards, similarly to the Hendo Hoverboard.
Inventor and Architect, Greg Henderson, wanted to utilize the Maglev train technology to lift houses and buildings out of harm's way caused by earthquakes and floods, and has stated "If you can levitate a train, why not a building?"
Maglev trains use alternating magnetic fields to control the speed, velocity, and direction of the train, which is what sparked Greg's idea to use electromagnets in the final design of his board's hover engines.
Greg went straight to work on his product, but because he and his wife Jill decided that going from lifting trains to two story buildings was too huge of jump of purposes, they decided to design something that was a lot more possible for them to accomplish, something that would take less time to perfect, something that would indicate the usefulness and abilities of the technology, and something that would appeal to everyone.
The idea of the hoverboard was born!
Right now there are only 10 in existence, but they plan to launch them for the select public in October 2015. (Again ironic because that's the same time period that "Back To The Future II" took place in.)
Many would say that the invention of the hoverboard is the most innovative, and the most important method of transportation of 2015, but...
The Hendo Hoverboard costs $10,000. (This doesn't include the copper platform needed)
You must be thinking: for $10,000 this should be the most awesome, and insane thing of the 21st century! Nope. It requires the platform below it be copper, possibly aluminum, or other non ferromagnetic metals because it can't induce an electromagnetic field into anything else.
The batteries are only good for 10 minutes of hover time.
Lastly, you would think the main purpose of a hoverboard is to hover off the ground correct? Well the Hendo Hoverboard has achieved this by managing to create lift of a whopping 1 inch off the ground!
Make it costs less money. ($1,000 should do)
Allow a longer Hover Time.
Create a stronger electromagnetic field that could lift the board higher into the air. (Possibly create a new copper alloy with even better conduction capabilities for a better electromagnet)
Lastly, get rid of non ferromagnetic platform restriction, and allow the rider to freely whiz through the air wherever they desire. (This could possibly be done by creating an oppositely charged electromagnetic field inside the hover engine itself, causing repulsion in the engine itself)
If all this is done, the hoverboard can be the greatest invention mankind has ever created.
As you can clearly see the Hendo Hoverboard is unimportant to the transportation world of today because of its small battery time, pricey cost, uesfulness in places other than a large sheet of copper, and pathetic hover height.
However the board requires a physical push from the rider, just like a regular skateboard would.
When the rider pushes off from the ground, their potential chemical energy is transformed into kinetic energy.
Make it cost less.
Stronger magnetic field, and battery to allow a higher hover height, and longer hover height.
If you're interested Here is Tony Hawk riding the Hendo Hoverboard:
The Hendo Hoverboard is a nifty method of transportation, but because of its poor floating time, poor battery life, and restrictions, it'll be a while before the hoverboard hovers to the top of the transportation chain.
Thanks for reading!
Allow the board to work on a surface other than copper.
