What I think needs to be done for this "free energy" to work. I know I will never get credit for anything in my life so its pointless. So what I think....
Is that you need to incorporate simplistic non working ideas. Use the flaws in each to excel and make a model that WORKS.
For example.
Electric cars. For the productivity of the energy and the waste product of using 100% electric to drive a car is not practical. SIMPLY subtract some batteries. Even if its half its still half the waste and battery use.
Now incorporate the idea of magnetic energy. Magnetic energy CAN work. Correct? But, not 100% since the power is so lacking. Generate some power from the battery while maintaining power from the magnets. Whether it powers an alternator or a dual aka hybrid motor.
Think of the flaws and work with it
Flaws, wind resistance equals lost energy right? Well generate the energy from the wind using a small fan type contraption that spins under the car. Preferably shaped like a wheel.As you drive the faster you go the resistance creates energy. Now the energy lost from resistance is gaining SOME efficiency back. Now magnets. Since its possible to re-magnetize something. How much energy do you think is lost from turning wheels? A LOT. SOO can't you take the concept of wheel spin and use the friction or spinning action that charges a magnet and use that for more power? These are just some of the concepts I think of that will never help me out in my future since I have no idea where to go or how to start making it happen.

One more thing. Ideas such as beta voltaic. A battery like that use 2 cubic feet of battery. Now you have a battery for a long time AND you have less waste and you have no bi-product. using this concept makes my idea from a year or so ago more stable and stronger.

Electric cars can work 100%. See the tesla roadster

The oil companies don't want you to have them so they don't make any R&D into making them. Imagine the efficiency we could have if they put their money behind a project of this type.

The additional energy gains you have thought about offsetting with the other conversions like wind to more energy wouldn't make enough power for them to be justified being there in the first place. They could possibly create more drag than energy as well, making them pointless, plus they would all add weight to the car making the engine need more power to move in the first place.

While these seem like good ideas, the problem is you can never recover that lost energy; you can never get more energy (or even the same amount of energy) out than you put in (whether that energy is in the form of a charged battery or a gallon of gas). Dan is absolutely right about adding weight and drag to the car.

The reason things like wind generators and other "free" energy devices work well on land is because wind from the rotation of the earth is free, while the wind from driving our car is not.

The only way to increase the efficiency of a car is to either reduce drag on the body or increase the efficiency of the engine. Funnily enough, electric engines are, in general, much more efficient than gas powered engines.

If you'd like more information on why these things (and things like why perpetual motion devices) are impossible read up on the second law of thermodynamics.

the beta voltaic battery would help a lot tho. Have you heard of it. the rest could even just be adding the the hybrids they have now. Wind does seem retarded but, I've heard people trying it with little success. Magnet cars and bikes have been in progress for a bit. Its just weird ideas

Since I live in the northeast part of the USA, electric cars for the most part suffer in the colder temps. I can't see how electric cars would work well in Canada anyways. But that isn't the point of my posting.

I've seriously looked into another technology that isn't limited to burning fuels or plugging in the megawatt machine. That technology is simply AIR. Not air like the wind farms, although that could be a good source to draw from, but air that actually moves the combustion cylinders of nearly every vehicle on the road today! Just think, remove the fuel system and control busts of high pressure air to move the cylinders up and down causing motion. Does this sound far fetched??? Well, check this link and others out on google by typing in air-car. http://www.theaircar.com

YouTube has a movie that's been seen nearly 500,000 times dealing with this technology! http://www.youtube.com/watch?v=QmqpGZv0YT4

A whole week of driving for just a few dollars rather than 60+ dollars for fuel.

The air goes in, and goes out. No emissions! No combustion needed. See the video above.

Forget the Smart cars and the like, the AirCar is something I really want!

Yeah, the french dudes are going to have to learn how to make a car that looks good before they will be able to sell those >_<

I always thought that the compressed air was more dangerous than petrol, and am not entirely convinced by his "the carbon fibre will just spilt [instead of explode]" line.

Many of today's vehicle fuel tanks are composites with fiber resins. Using Moldflow analysis software and testing, tanks are engineered to rupture in safe and controlled methods within the realm for accidents.

My full size van with the 38 gallon composite fuel tank is no different. So, having air in the tank vs. 87 octane fuel seems to be a better option.

There are many vehicles running on compressed natural gas (CNG) around the country for the last three decades. So, compressed air should be easier to manage and transport without issues. We have some vehicles, buses and delivery trucks that run on propane. Not only that, but many warehouses use propane trucks to move inventory around too.



What I would be alarmed about is if the air wasn't basic air, but pure oxygen!

You have to look all the way down the chain to find out how much energy is used to make each type of fuel. Air cars are still going to be using fossil fuels because SOMETHING has to run to compress the air. Unless you have a compresser running on wind or solar energy. Hydrogen cars have the same downfall. How do you get the hydrogen? a special converter that runs on electricity!

Electric cars seem to be the best energy conservers out there, but you're right, the oil companies can't afford (well, they can) to lose fuel consumers to electric vehicles.

i was under the impression it ( the air car) uses a battery that keeps charge from an alternator to compress the air

or you could have a generator that runs on gas to make the electricy to turn the compressor to compress the air for the motor

In the video, they do just that. However, on one tank full of petrol and running the air compressor, you can travel from LA to NYC.

That would be awesome to travel across country for under $70 dollars in fuel costs.

You just described perpetual motion, which is currently impossible.

Not only currently impossible but completely impossible according to our current laws and understand of physics so anyone thinking of building a perpetual motion device would fare much better trying to invent a motor with better efficiency; however, using the brakes to charge the battery would help to increase efficiency.

vicaphit wrote:Hydrogen cars have the same downfall. How do you get the hydrogen? a special converter that runs on electricity!

Not necessarily, chemists are currently looking at a (promising) type of laboratory-made bacteria that can split the bond between hydrogen and oxygen, thus giving us two fuels (hydrogen and oxygen) from the most abundant resources on the planet (water and bacteria)! [link]
Also, biologists are in the (very) early stages of replicating the process of photosynthesis to create more efficient solar panels.

I've seen the compressed air cars but kinda dismissed them as a novelty, I'll have to give them a closer look if they're really that efficient...as for the beta voltaic batteries, I believe it's an interesting idea that's not going to be viable for some time.

I'd have to agree, aren't the french right across the english channel from you guys? Why don't they get together with Aston Martin or Lotus to make a car that not only looks good (english) but runs good (french)...it just makes too much sense I guess...

well i didnt see the video(do you have any idea how long it takes to open a video with dialup i dont have that kind of time), but i now have Roadrunner high speed cable


and think of Nearly perpetual motion, it powers itself, but it DOES lose power as you drive it

skierkid450 wrote:and think of Nearly perpetual motion, it powers itself, but it DOES lose power as you drive it

Well, if you can find a way to harness the waste energy (such as heat generated by the brakes) that would work great but by using the engine to compress the air wouldn't make sense; think about it like this, if you just used the air pressure from an air compressor to power the air compressor, you would just keep losing energy because 100% efficiency can't be achieved. Therefore, it's more efficient to just store that energy in it's original form (compressed air in a tank). Of course, you do need some form of outside power to compress the air in the first place but you don't have to use fossil fuels; instead you can use solar power, human power, biofuels or some other form of green energy.

You would need to use some of the air pressure's power to keep a battery charged for creature comforts (such as A/C and lights) but it would be foolish to turn around and use the battery to compress more air because you will lose a good deal of energy in the process (air pressure > battery > air pressure).

I love the challenges of building a more efficient engine and finding new forms of energy but the biggest challenge is finessing you way around the laws of physics. BTW, I'm loving this idea of compressed air engines but then, simple things like that excite me

I've had an idea for a couple of years.
Without changing engines or current forms of propulsion at all, there is another way to generate extra power from vehicles that are already on the road.

How many vehicles do you see going down the highway every day??
Well every single time one passes, there is energy that is going to waste.

That vehicle generates wind as it drives by any given point.
Maybe something could be mounted on the roadside to use that wind .....

Also, I think some sort of device could be mounted in the roadbed that when said vehicle runs over it, maybe it spins, maybe it simply collapses.
Either way, it could be made to drive some sort of "mini - generator".
Thereby producing a small amount of electricity and putting it into the power grid.
Maybe each mount point wouldn't generate very much ... but if there were thousands of these things .... well you get the idea.

Like I tell my lovely wife ....
Very few of my ideas might be worth a crap ... but I damn sure have a bunch of 'em!

That is a very intriguing idea, in theory at least, but I think it would be hard to 'capture' that small of an amount of wind energy (wind energy is hard to capture anyway) at the side of the road. As for running over something in the road, not only would the component have to be quite sturdy it would also require a good deal of upkeep and, if not well designed, could make drive quite...bumpy. It's a pretty good idea though because it would harness waste energy without affecting the efficiency of the car...INteresting.

I still think that the only way we'll get our cars to be a much higher efficiency is to change fuel sources and get away from fossil fuels (you can only squeeze so much out of them). Electric cars are starting to show a lot of promise (even for us speed freaks). In my opinion, we need to slowly phase out gasoline cars and switch to electric cars. Where are we going to get all the electricity? Nuclear power of course! Then again, the majority of America is afraid of nuclear power (even though it's one of the safest and most efficient ways to produce electricity) so that may not happen in the near future. Oh well...

Chernobyl!

Kidding. In northern Ohio, near where my grandparents live, there is a Nuclear power plant built on a fault line, and it hasn't had any trouble yet! (my grandparents have cracks in their plaster from earthquakes though.

Hey! back in the early 1980's I toured a nuclear power plant east of Cleveland. I wonder if it's the same one?

Well for any fuel not being fossil, hydrogen is the next answer years down the road.

hydrogen is a much better option. and in using it as a car needs it. Not like 2000 miles per refill. But, more reasonably 500 miles per refill. It can be safe enough. I think they could mix it with carbon dioxide if they do worry about an explosion. This would make it more safe and less... explodable? lol I don't think its a word but, today it is. Thanks to Chris Cotton aka Hercules71185 word of the day is explodable.
