Tesla Levitation is not really levitation. If you put the triangle in a vacuum and try to get it to levitate it will fail. While the Quantum leviation should continue to work, even in a vacuum. This means the Tesla Leviatation is really more like a propulsion system than leviation. As I understand it, it super heats the air around the wires. This, however, is the limit of my physics understanding.

I'm just making a point that "Tesla Levitation" is more feasible than Quantum Levitation when it comes to practical uses such as train.

If we're gonna get deep and dirty in this engineering subject... "Tesla Levitation" (notice the quotation) would be a misnomer because it implies Tesla technology is levitating a train when it's actually not. A train would be using Tesla technology to power the levitation technology because it would be cost-effective and energy-efficient that way.

and again back then you would be living in a cabin with dirt for your floor most likely. You sure that will not change your thoughts?

People could not EVEN accept the fact a car could go 35 mph at that era. It was mind blowing.

try me :)

at that time - people thought computer and PDA were silly. not me.

Dry ice is used on a commercial scale - it is used in poultry processing to keep chicken product frozen longer during long transports from one facility to another or if it will be placed in storage for an indefinite amount of time. 99% of the chicken product you purchase from the store has been in contact with dry ice at some point in time. Keep in mind there is usually a thin plastic barrier between the product and the dry ice to prevent the meat from coming in contact with what USDA deems as a foreign substance.

Even a small poultry processor such as PJP used dry ice in it's facilities.

If done right, it's possible for this type of transportation to be used on a commercial scale despite it's danger.

Just saying the use of dry ice is already in commercial use. These guys just worked on a concept for using it in transportation.

I just hope it succeeds so maybe we can find more environmentally sound yet efficient ways of moving people and goods across distances.

Yeh, true that, but one diminishing feature about Dry Ice is that the contents are rarely exposed to the atmosphere on a consistent basis. Also, we have no idea if there are adverse health effects for the air if it is used on a mass scale purpose -human transportation use, as some of you are imagining. Since dry ice hasn't reached a point where it is used outside of a controlled environment, the practicality is very much the question. There are health hazards with usage of dry ice in large amounts, if I recall correctly from chem lab.

Overall the concept is great, but like some of you said, it might take a long time until actual prototypes can be made into frutition. There's also going to be the EPA judging the overall pros and cons of manufacturing such a large scale device, if it doesn't make the cut, you can be sure it'll kill some people's dream cars.

I do see this coming though, just probably wayyy later when it's my future grandson/granddaughter's time and they are 50 years old.
 
Jiro - I agree! :) Boy, I wish I could debate quantum physics with you. I just don't have the knowledge to do so. Bummer because I love this area of science.

If I'm not misstaken, you will need something colder than dry ice to make this work.

yep. hence.... "supercooling".

Quantum Levitation needs nearly 3-4x colder than Dry Ice.

Quantum Physics???? debate??? good gracious! I refuse! because it boggles me! :dizzy:

I'm just defending my position with engineering perspective because I used to major in electrical engineering at Virginia Tech.
 
Solid CO2 sublimes and becomes gaseous- its one way to put an animal 'to sleep'
 
(I just don't know when to quit! :) )

According to the materials. Different materials require different levels of cooling to achieve superconductivity. The search is on for materials that can superconduct at more practical temperatures.
 
Where did dry ice come from?

It looks like they were using liquid nitrogen to freeze the semiconductor.

Liquid nitrogen is three times colder than dry ice.

Dry ice evaporates at -109 deg F. (Not really evaporation.. sublimation)
Liq Nitrogen evaporates at -321 deg F.

Just giving people an idea of how cold the semiconductor must be for this to work.

However, I am not a party pooper like Jiro. I do hope future technology comes out of this that would blow our minds today.

Oh you beat me....

I don't think I like you no mo!

I can't believe we went "skiing" together. UGGGG!!!

Just saying since these guys have a concept of sorts, dry ice might be more practical since it is easier to keep cold than liquid nitrogen. But then again perhaps these extreme cold temps of liquid nitrogen is needed for this to work. Both are dangerous, but transportation like this isn't completely impossible. It will take time for it to be fully developed. I wouldn't expect this before my grandchildren have grandchildren of their own.

the thing is.... what you were talking about before - dry ice was used to keep chicken product fresh.... not to keep train running.

I don't doubt that we will eventually have a transportation based on quantum levitation but like EV-1 car, it will be short-lived. And since you talked about liquid nitrogen. Look at our space shuttles. It's also powered by liquid nitrogen and other liquid fuels. It's funny that for the past few decades - our space shuttles and space rockets have gone thru numbers of technological advancements. and yet.... it's still using same power source - liquid fuels.

Looking at our past - it's more practical and cost-effective to control hot temperature than to supercool it. none of our powering technology requires supercooling... only coolant :lol:

Just so you know, I've handled rocket fuel, its a solid. Feels like rubber.

Just put commuters and travelers on dry ice and ship them. :giggle:
