Somewhat baffled by "synthesis gas" since methane is an excellent feedstock - I can imagine CH4 -> CO + H2 being an intermediate reaction within some other synthesis but it seems unlikely to extract and bottle it.

However partial oxidation of coke has played an important part in industry and transport. First, heat coal or wood to extract lots of useful volatiles (tar, oil, etc) then use the carbon residue

1. 2C + O₂ -> 2CO + heat (producer gas)
2. C + H₂O -> CO + H₂ - heat (water gas)

You cycle the two reactions to keep the coke between red and white heat, and store the mixed product as a very useful fuel.

"Inhaling liquid nitrogen" seems a pretty extreme activity.

That's why nobody does it.
Why did you raise the idea?

You did!
https://www.livescience.com/57779-how-liquid-nitrogen-can-kill.html

But why is inhaling liquid nitrogen so deadly, given that nearly 80 percent of the air people breathe is made up of nitrogen?

The article mistakenly ays "inhaled liquid nitrogen" at one. point, but then clearly explains how a tank of LN2 can rupture, allowing the liquid to vaporize and displace all of the air in a room.

Alan, don't you work with MRIs? I assume you know what happens when a magnet quenches...

For those who don't already know, superconducting magnets have to be kept very cold (for now). This is commonly achieved by using liquid helium to maintain a frigid 4 degrees Kelvin, which is kept inside another container that is kept at a balmy 77 degrees Kelvin with liquid nitrogen, to avoid heat transfer with the outside air, which is typically around 300 degrees Kelvin. Very high currents are passed through the superconducting coils to produce the magnetic field, but if something goes wrong and the helium evaporates, then the wires' resistance rises from zero, and essentially act as a resistive heating element, causing the liquid nitrogen (and any remaining liquid helium) to boil off very quickly (sometimes explosively). The amount of liquid nitrogen in a machine the size of a small car can easily displace all of the air in a warehouse within seconds!

The companies that search for and extract fossil fuels are heavily subsidized,

Search, yes, but production is hugely profitable once the geologists and drillers have found the stuff. Same as mining. It's an academic question as to whether paying prospectors and trial drillers (who can't guarantee success) counts as subsidy or research investment. I certainly don't see any governments giving taxpayers' money to production and refinement except where production is actually state-owned.

Alan, don't you work with MRIs? I assume you know what happens when a magnet quenches...

Indeed. But suffocation incidents are usually associated with the loading and cooling process, not a subsequent quench. We have exhaust stacks to vent quench gas safely once the magnet is assembled.
My own MRI units  used room-temperature resistive magnets or high-temperature supercons cooled with gaseous helium, but now I'm working with other people's kit, fraught with the dangers of liquid refrigerants.
Fortunately modern MRIs don't use nitrogen - one less problem - and capture helium boiloff, saving a lot of money. Time was that liquid helium was cheaper than beer when vast quantities were used for North Sea divers maintaining oil and gas rigs, but so much was exhausted to the cosmos that it is now more expensive than champagne.

I offer to use CO2+H2O to convert it into CO+H2. Its going to be super easy.

How?

Many ways to convert CO2 into CO. CO2 can be mixed with calcium, natrium, lithium and many others. That give opportunity to make a product during CO2 to CO conversion. Or directly CO2 => 2CO. H2 from water and O2. High pulsating DC would do the job faster.

[Bored chemist]

calcium, natrium, lithium and many others.

All of which are much more expensive than natural gas.
So what would be the point?

[vdblnkr34 (OP)]

No its not. It would be very low cost. If to use hydrogen gas gotten for free.

No such thing as free.

The Laws of Thermodynamics are, unfortunately, not able to be revised, amended, or repealed. They are (roughly):
1) You can't win
2) You can't tie
3) You have already started the game

[Bored chemist]

If to use hydrogen gas gotten for free.

Why do you keep  ignoring the fact that you can not get things for free?

[vdblnkr34 (OP)]

Its old expression.   Of course nothing is free. I meant hydrogen/oxygen gas will be for free electrical power generated by the electrical dynamo machine. Solar power. I just repeat myself.

[Bored chemist]

If we have solar power- cheaply-  why would we worry about not having natural gas.

You seem to be ignoring the fundamental laws of physics and economics here.

I meant hydrogen/oxygen gas will be for free electrical power generated by the electrical dynamo machine.

The dynamo does not, and can not ever produce free power.
Please learn that simple fact.

[vdblnkr34 (OP)]

Of course it does. What is the electricity magical ability. Size is no matter, amount does. What is the magical ability of the material, size matters.

There is no such thing as an over unity device. Every time somebody says they have made one, it is either a scam, or they have fooled themselves, and think they are "close." Please don't waste your time on such things.

[alancalverd]

My invitation remains open. Bring me a device that actually produces more energy than it consumes and I will find engineers and investors to commercialise it. Absolute secrecy and 10% of the profits guaranteed.

It's tempting to offer to outbid Alan by offering 50%, or even 90%, of the profits. But the reality is I'm happy to let him deal with the cranks who think they can meet the requirement.

[alancalverd]

Cranks may care to read the small print in my contract. There is a very substantial consultancy fee for examining the prototype.

Here it is. Upgrade for dynamo machine. Rotorless generator.
