wouldn't a compressed air engine work the same way as a Steam engine?
hook an air compressor up to a steam engine and it works.

Yes in the sense that it involves the direct conversion of hydraulic energy to mechanical energy.

My own experiments conducted as an apprentice to the work of Dr. J.B. Howard at MIT (back in the year 2001).

Along with Argon, the diatomic molecules (O2, N2, H2) are small enough to get absorbed into fullerenes at pressures greater than 5000 psi. Oviously the first two species on that list represent the bulk of air. The larger components in air CO2, H2O, CH4 and the pollutants NO2, O3, etc..., tend to be filtered out of the fullerenes when exposed to that compression process. But hey, that only makes those fullerenes that much more useful as a source of combustion air. Why? Because of Hess's law...

In retrospect of my previous post however, eliminating the pressure problem also eliminates the source of power for said vehicles - as in, it is the decompression of the pressure head which powers the vehicle. You remove that pressure, and you remove its functionality. I guess it couldn't be worse than strapping oneself on to a scuba tank.

OK, I thought you meant they formed the Bucky Balls as well. You mean being trapped into the C60 molecules, or nanotubes.

Yes, that is also the solution that makes hydrogen storage safe for fuel cell vehicles, or even hydrogen powered internal combustion engines. Still, 5000 PSI is pretty high to trap oxygen. Once trapped, how low can you reduce the pressure and keep the oxygen trapped? Is it a safe pressure?

It diffuses out of the fullerenes at rates dependent on the temperature. As for flow... you would have more than enough if you designed a container that operated at about 5-8 psig.

Again though, I initially jumped the gun on my prior post... While solving the safety problem posed by the pressure... I also negated the functionality of those vehicles. Those vehicles work off of the energy that is provided by the thermodynamic decompression of the gas - at that point the safety risks are inherent to the design of the engine and cannot be eliminated.

Blow me you ing commie . And I didn't realize my post here on Spurstalk had the power to stifle experimentation for alternative fuel sources half way around the world.

That was some funniy right there. Good to see Boutons getting on, on a regular basis.

Looks pretty "dangerous" and "inherently risky" to me. All that air from a punctured tanking just waiting to hiss you to death.

I posted this once before, but I wonder if this guy has maybe really
hit upon something. WC, you being an electronics guy, what do
you think.

Salt water as fuel, using radio waves.

Well, this is more a chemistry issue than electronics, but I do know basic chemistry too. Consider the formula:

2 NaCl + 2 H2O → Cl2 + H2 + 2 NaOH

This is most likely what is occurring. It is extremely unlikely that the radio waves are only disrupting the hydrogen oxygen bonds. Notice how poisonous chlorine gas and the base sodium hydroxide is formed... Extra energy is also formed when the free hydrogen burns with oxygen in the air.

Rather than using an anode and cathode to have an electrolytic reaction, the radio waves create an electrical field inside the salt water like a microwave oven excites and heats food.

Now it is possible that he found a frequency that liberates the oxygen and hydrogen only. However, if that were the case, more energy is being used to create the radio waves than the heat produced in burning the liberated fuel. Otherwise we have perpetual motion. Not to have the poisonous chlorine released, or the sodium hydroxide, means it stays in the solution as salt. As the water burns, it gets more concentrated. The answer would be to make it a closed system. As the system operates, cool the steam back to water and put it back in the salt solution.

Anyone here believe in perpetual motion? Isn't it convenient that there is no mention of power used vs. power generated?

There are various sites if you search his name. I found nothing to indicate power efficiency, but did find someone else mention the poisonous chlorine released.

There might be a practical use for the sea water idea after all. I'm not going to do the equations, but it has to do with thermodynamics.

When salt is added to water, it gets colder. What happens is the ionic changes in the solution take energy out of the water. Therefore there is more energy to start with. I don't know the extent, but it is feasible that slightly more energy can be extracted in heat than the power applied in the form of radio waves.

Still, if he hasn't stumbled on a frequency that keeps the salt ions intact. this is a poor solution unless we are going to sequester the chlorine gas and sodium hydroxide. I believe it is these additional reactions that make the process appear so viable. How much power is then lost in sequestering them?

Compressed Air Energy Storage to Experience Dramatic Growth over the Next 10 Years

Traditional underground compressed air energy storage (CAES), which is one of only two proven long-duration bulk storage technologies, has been commercially available for more than 30 years. While no new CAES plants have been deployed since 1991, project activity and interest in the technology has grown in recent years, and higher-efficiency next-generation CAES technology is also nearing commercialization. According to a new report from Navigant Research, more than 11 gigawatts of CAES capacity will be installed worldwide from 2013 to 2023.

“Rapidly changing energy mixes and increasing renewable energy penetration will continue to introduce instability onto electricity grids worldwide in the coming years, while the volatility of load profiles will challenge grid operators to deliver reliable and secure electricity,” says Kerry-Ann Adamson, research director with Navigant Research. “These macro conditions will drive demand for CAES, helping to rejuvenate a sector that has been largely dormant for the last two decades.”

Growth in this sector will also be driven by advances in isothermal, or adiabatic, CAES, which can be sited anywhere and conveniently scaled using modular units. A handful of players are innovating in this space, and their technology will be commercially validated in the next 12 to 36 months, the study concludes.

Thereport, “Compressed Air Energy Storage”, analyzes the global market opportunity for both traditional underground CAES and next-generation CAES technologies across five key application segments: wind energy integration, solar energy integration, grid asset optimization, transmission and distribution deferral, and ancillary services. The report provides a comprehensive assessment of the demand drivers, policy factors, and technology issues associated with the market for CAES. Key industry players are profiled, and worldwide capacity and revenue forecasts, segmented by application, technology, and region, extend through 2023. An Executive Summary of the report is available for free download on the Navigant Research website.

Looks like a bunch of hot air.

UPS is using a pretty souped up version of this.
