Rocket fuel and car fuel are very different, and you cannot put rocket fuel in an ordinary car. Rocket fuel is highly corrosive, volatile, and dangerous, and it can easily ignite and explode. It is also challenging to store, as some types need to be kept at extremely low temperatures. Cars need to run safely and efficiently, and rocket fuel is not suitable for this purpose. However, some types of rocket fuel, like RP-1, a high-grade kerosene, are similar to diesel fuel and could potentially be used in diesel engines with minor performance issues on cold days due to higher viscosity.

Rocket fuel is too dangerous, volatile, and expensive to be used in cars
Rocket fuel is not suitable for use in cars due to its dangerous, volatile, and expensive nature. Firstly, it is highly flammable and explosive, which poses significant safety risks for vehicles operating on public roads. The corrosive nature of rocket fuel further exacerbates the potential dangers. In contrast, commonly used car fuels such as gasoline, diesel, and natural gas are less likely to ignite and are therefore safer options.
Additionally, rocket fuel is designed for use in rockets, which have very different fuel requirements from cars. Rockets utilize both the chemical energy content and the kinetic energy of the fuel, resulting in high fuel efficiency, especially at slow speeds. On the other hand, cars primarily rely on chemical energy, and their fuel efficiency decreases at low speeds due to the constant relationship between fuel usage and velocity. The difference in fuel requirements between cars and rockets highlights the unsuitability of rocket fuel for automotive use.
The volatility of rocket fuel also presents challenges for automotive use. For instance, liquid hydrogen, one type of rocket fuel, requires storage at extremely low temperatures, below -432°F. Maintaining such low temperatures in a typical garage setting would be impractical and technologically challenging. Kerosene, another rocket fuel similar to diesel, has lower volatility but higher viscosity, which could affect engine performance on cold days.
Furthermore, rocket fuel is expensive compared to conventional car fuels. The high cost of rocket fuel is due to the specialized nature of its composition and the extreme conditions it is designed to withstand during space missions. The economic feasibility of using rocket fuel in cars is questionable, especially considering the availability of cheaper and more readily accessible alternatives like gasoline, diesel, and natural gas.
In conclusion, while the idea of powering cars with rocket fuel may capture the imagination, the practical realities present significant obstacles. The dangerous, volatile, and expensive nature of rocket fuel makes it ill-suited for use in cars, which require safe, efficient, and cost-effective fuel options.

Liquid hydrogen, a type of rocket fuel, could work in diesel cars but is challenging to store
Rocket fuel is not suitable for use in cars as it is too dangerous, volatile, and expensive. It is highly flammable and explosive and can easily damage a car. However, Manuel Martinez-Sanchez, a professor of aeronautics and astronautics at the Massachusetts Institute of Technology, suggests that liquid hydrogen, a type of rocket fuel, could work in diesel cars. This is because liquid hydrogen was the fuel that powered the space shuttle's main engines.
Nevertheless, there are challenges associated with using liquid hydrogen in cars. One significant obstacle is storing it, as liquid hydrogen must be kept at an extremely low temperature of below -432°F. Maintaining this temperature in a typical garage setting would be difficult. Additionally, there is a risk of the engine freezing. RP-1, a kerosene-based fuel similar to diesel, is another potential option for diesel engines. However, it may not perform well in cold weather due to its lower volatility and higher viscosity.
The incompatibility between rocket fuel and cars lies in their differing fuel requirements. Cars are designed to operate safely and efficiently on roads using fuels such as gasoline, diesel, and natural gas. These fuels are less volatile and expensive than rocket fuel, making them safer and more practical for everyday use. In contrast, rocket fuel is highly specialized for use in spacecraft and is not suitable for the typical operating conditions of cars.
Furthermore, the efficiency of a car's fuel usage differs significantly from that of a rocket. Cars are most efficient at low speeds, whereas rockets require a significant amount of energy to accelerate from a slow speed. At high speeds, a car becomes staggeringly less fuel-efficient than a rocket. This is because cars accelerate by pushing against the ground, which becomes increasingly difficult as the speed increases.

RP-1, a kerosene-based rocket fuel, is similar to diesel and could be used in diesel engines
RP-1, or Rocket Propellant-1, is a highly refined form of kerosene-based rocket fuel. It was developed in the 1950s as a more efficient alternative to alcohol-based rocket fuels and has been used in spacecraft such as the Soyuz and Falcon 9. RP-1 is similar to diesel fuel and can be used in diesel engines without any significant issues. According to Manuel Martinez-Sanchez, an aeronautics and astronautics professor at the Massachusetts Institute of Technology, RP-1 is "a close relative of diesel fuel," and the only potential issue with using it in diesel engines is its lower volatility and higher viscosity, which may affect engine performance on cold days.
RP-1 is a highly refined hydrocarbon with a strict set of specifications that make it suitable for use as rocket fuel. These specifications include very low levels of sulfur, olefins, and aromatics, as well as an increased number of branched-chain alkanes, which improve thermal stability. The refinement process for RP-1 involves multiple steps to increase fuel density, improve engine performance, and meet the specific requirements for use in rockets.
While RP-1 is similar to diesel and can be used in diesel engines, there are some key differences in their compositions. Diesel fuel undergoes a refinement process to become a relatively simple form of propellant, but it does not meet the same strict specifications as RP-1. The refinement process for RP-1 is more complex and expensive, making it a much more costly fuel than diesel. Additionally, RP-1 has lower volatility and higher viscosity than diesel, which could impact engine performance, especially in cold weather conditions.
Despite these differences, RP-1's similarity to diesel fuel means that it could be used in diesel engines without any major modifications. However, the performance of a diesel engine running on RP-1 may vary, and it may not be as efficient as when using diesel fuel, especially in cold temperatures. Therefore, while RP-1, a kerosene-based rocket fuel, can technically be used in diesel engines, it may not be the most optimal choice for everyday use due to potential performance and cost considerations.

Cars with jet engines have set many land speed records, but they may not be considered cars
While it may be theoretically possible to put rocket fuel in a car, it is not a simple task. Rocket fuel, such as liquid hydrogen, needs to be stored at extremely low temperatures, below -432°F, which would make storing it in a garage challenging. Kerosene-based rocket fuels like RP-1, on the other hand, are similar to diesel fuel and could potentially be used in diesel engines, although they may not perform well in cold weather due to their lower volatility and higher viscosity.
Cars with jet engines have a long history in setting land speed records. The practice of fitting cars with aircraft engines dates back to before World War I, but it was in the interwar period that military-surplus aircraft engines became readily available, powering numerous high-performance racing cars. In the 1960s, jet engines began to appear in cars, with the General Electric J47 engine powering three different cars at Bonneville in 1962. These cars achieved speeds of up to 400 mph (640 km/h). In 1964, Art and Walt Arfons arrived at Bonneville with jet cars of their own, with Art's Green Monster setting a world-record speed of 434 mph (698 km/h).
The 1960s saw a fierce competition between Breedlove, Walt Arfons, and Art Arfons to break land speed records. Breedlove's "Spirit of America" broke the 500 mph (800 km/h) barrier in 1964, and in 1965, he recorded a speed of 600.601 mph (966.574 km/h) at the Bonneville Salt Flats. This record was broken in 1970 by Gary Gabelich, who piloted the rocket-powered Blue Flame to a speed of 622.407 mph (1,001.667 km/h). In 1983, Thrust2, powered by a Rolls-Royce Avon jet engine, set a new record of 633.468 mph (1,019.468 km/h).
Despite the success of jet-powered cars in breaking land speed records, there is some debate as to whether these vehicles can truly be considered "cars". The term "car" or "automobile" is typically associated with vehicles that have internal combustion engines or electric powertrains. Jet-powered vehicles may fall into a different category due to their unique propulsion systems and performance characteristics.

At high speeds, cars are staggeringly less fuel-efficient than rockets
Rocket fuel and car fuel are very different, and it is not advisable to put rocket fuel in a car. Rocket fuel is highly volatile, dangerous, and expensive. It is also very corrosive and can easily ignite and explode, making it unsuitable for use in cars. Cars need to operate safely and efficiently on roads, and rocket fuel does not allow for that.
However, it is theoretically possible to use some types of rocket fuel in certain types of cars. Liquid hydrogen, for example, was the fuel that powered the space shuttle's main engines, and according to Manuel Martinez-Sanchez, a professor of aeronautics and astronautics at MIT, it could be used in diesel cars. That said, liquid hydrogen needs to be maintained at an extremely low temperature (below -432°F), which would make storing it in a garage quite challenging. It could also freeze the engine.
RP-1, a kerosene-based fuel, is another option. Developed in the 1950s as an alternative to alcohol-based rocket fuels, RP-1 is quite similar to diesel fuel and was used in the Soyuz and Falcon 9 spacecraft. Martinez-Sanchez states that RP-1 could be used in diesel engines without any significant issues, although its lower volatility and higher viscosity might cause the engine to perform poorly on cold days.
While it may be technically possible to use certain rocket fuels in specific types of cars, it is important to note that cars and rockets have fundamentally different propulsion systems. Cars push against the ground to move forward, and as their speed increases, it becomes increasingly difficult to push against the receding ground. This results in significantly reduced fuel efficiency at high speeds compared to rockets.
Rockets, on the other hand, start at slow speeds and use their fuel to accelerate. As the rocket gains speed, the fuel also gains kinetic energy, which can then be used to further accelerate the rocket. This process allows rockets to achieve extremely high speeds while maintaining fuel efficiency. Therefore, at high speeds, cars are far less fuel-efficient than rockets.
