A hot/cold hybrid automobile drive train uses fossil fuel to run a small engine that compresses its own products of combustion, mixes it with liquid nitrogen that runs pneumatic engines that power the drive wheels of the car.
Typical internal combustion engine vehicles are less than 20% efficient because they loose large amounts of energy out of the radiator, tailpipe, radiation from engine parts and drive train friction. The Hot/cold hybrid drive train system uses both sides of the thermodynamic equation to produce kinetic energy to power the car. The heat generated by the burning of fuel and the compression of the products of combustion mixes with and boils the liquid nitrogen creating high pressure utilizing heat that would normally be lost. The liquid nitrogen absorbs enough heat to go from ?196 °C or ?321 °F to over the boiling point of water. If the liquid nitrogen were not confined to its pressure tank it would fill a volume nearly 700 times its liquid volume.

Car Concept
This concept drawing shows the small internal combustion engine to the left, attached in line to a compressor. The exhaust from the engine goes directly into the intake ports of the compressor. As the exhaust gasses are compressed they become hotter. At this point the hot compressed gasses are mixed with liquid nitrogen through a special valve. The mixture passes into a tank which has provisions for removing water before being used in the pneumatic engines located as close to the drive wheels as possible.
So Where Do We Get That Much Liquid Nitrogen? Answer: Windmills
The largest problem with wind electric power generation is that for every megawatt of power a windmill may produce you need to provide an equal amount of alternate electric power somewhere else that can operate when the wind isn’t blowing. The alternative power station must be able to go on and off as the wind changes and respond immediately to demand. Windmills also have problems operating in very cold weather.
This proposal solves several problems.
Windmills could be designed to directly power large capacity compressors connected directly to the wind turbine in the nisscell at the top of the mast. The Von Linde system of converting gasses to liquids would be used which essentially uses a multi-step process where air is repeatedly compressed and cooled. The initial cooling fins containing hot water which is a byproduct of the Von Linde process could be located in the routers of the windmill which would make it usable in even the coldest weather when normal windmills are dangerous to operate because of icing. Windmills used to generate liquid nitrogen would work best in near blizzard conditions when the wind is blowing hardest and the cooling system is most efficient.
If windmills were used to make liquid nitrogen, when the wind did not blow it would not cause the immediate need to turn on an alternate power generator. Tanker trucks would pick up the liquid nitrogen when the wind mill’s tanks were full. Wind mills can be located close to where you need to fuel your vehicle instead of Saudi Arabia.
Use Locally Available Fossil Fuel
It is easy to operate small engines on liquid natural gas by changing the carburetor and adding a pressurized tank to hold the fuel. Liquid natural gas is energy dense. Not only does it contain the energy of combustion but also, like the liquid nitrogen, it has a reserve of energy contained in its heat of vaporization that can also be used to help propel your future car.
Symbiotic Uses of Local Power
The flow chart above shows several ways to produce liquid nitrogen and the byproducts that can be gleaned from the process.
Symbiotic relationships with other industries could be formed. An example of that would be a hospital located near windmills that could use the hot water, oxygen, and xenon produced in the process of generating liquid nitrogen.
Steel mills that use a lot of oxygen could form symbiotic relationships with auto fuel suppliers by supplying them with nitrogen rich gas left over from separating out the oxygen.
Welding supply companies use argon and oxygen and could liquefy the nitrogen for use as auto fuel.

Conservation of Flint
This is the result of a study to see how many usable points and tools that I could make from one flint cobble like the one in the upper right. The debitage pile amounted to a small handful of possibly usable micro chips which are not pictured here. The points at 1 and 2 o’clock were made with a single strike of the baton. The next four points clockwise are either uni-facially or bi-facially knapped. They were made from the flattest of the prismatic blades struck from the core at the center. The core has some usable material left. It is a handy size and shape to carry on a hunting expedition in a pocket.
These points did not take much time to make and while they are more fragile than points made by bi-face reduction, they are somewhat disposable because of the lack of time invested in making them. This project took me about 2 hours to complete. Most of the time was spent retouching the four uni-facially or bi-facially knapped points. The two points in the lower right show the difference between a uni-facially knapped and bi-facially knapped points.
Points and tools of this kind were often produced in Europe 18,000 to 10,000 years ago by cultures of the upper paleolithic in western Europe. Many of the tools were used to carve very intricate tools and weapons of ivory and reindeer antler. High levels of art were evident during this period which lasted until about the end of the last ice age.
Prelude to Traditional Fletching is a new video just completed by Thunderbird Atlatl. The video shows how to make traditional thread using hemp fiber. This is a great video for those wanting to learn the techniques for traditional fletching.
We’re planning to release new videos on this site so be sure to keep checking back.
