Fuel Query: Converting Liquid Oxygen & Ethanol into Mechanical Energy

In summary, The conversation discusses the idea of using a former rocket fuel, specifically a mixture of liquid oxygen and ethanol, for a terrestrial purpose. The speaker, with a background in molecular biology, is seeking information on the engine elements and equations needed to convert this fuel energy into mechanical energy. They also mention that ethanol is currently used as a gasoline replacement and suggest using the Earth's atmosphere as a source of oxygen instead of producing liquid oxygen, which is expensive. The other person adds that the current price of liquid oxygen is cheaper than gasoline or diesel in the UK, but using air as a source of oxygen would be even more cost-effective.

I write as one with a background in molecular biology and nothing in engineering. Looking to advance an idea of using a former rocket fuel for a terrestrial purpose. A mixture of liquid oxygen and ethanol was used in past decades.. What engine elements would be required to convert this fuel energy into some type of mechanical energy... say to turn rotors. What equations would be involved in such a case. Much thanks in advance for an informed reply.

Ethanol is used now as a gasoline replacement for many engines.

Liquid oxygen, LOX, is too expensive to produce for use on the Earth's surface. Instead, use the atmosphere which is about 20% oxygen. That will also save significantly on transportation costs.

Hmm... the current price per liter of LOX is cheaper than gasoline or diesel in the UK. But of course air is free.
 

What is the process of converting liquid oxygen and ethanol into mechanical energy?

The process of converting liquid oxygen and ethanol into mechanical energy is known as fuel combustion. It involves the chemical reaction between the liquid oxygen and ethanol, which results in the release of heat energy. This heat energy is then converted into mechanical energy through the use of an engine or motor.

What are the advantages of using liquid oxygen and ethanol as fuel for mechanical energy?

One of the main advantages of using liquid oxygen and ethanol as fuel is that they are cleaner burning compared to traditional fossil fuels. They produce fewer emissions and therefore have a lower impact on the environment. Additionally, both liquid oxygen and ethanol are readily available and can be produced from sustainable sources.

What are the potential drawbacks of using liquid oxygen and ethanol as fuel for mechanical energy?

One potential drawback is that liquid oxygen and ethanol have lower energy densities compared to traditional fossil fuels. This means that a larger volume of fuel is required to produce the same amount of mechanical energy. Additionally, the storage and transportation of liquid oxygen and ethanol can be more complex and expensive compared to traditional fuels.

Are there any safety concerns when using liquid oxygen and ethanol as fuel?

Yes, there are some safety concerns when handling and storing liquid oxygen and ethanol. Both substances are flammable and can be hazardous if not handled properly. It is important to follow safety protocols and regulations when working with these fuels to ensure the safety of oneself and others.

What advancements have been made in the conversion of liquid oxygen and ethanol into mechanical energy?

Advancements in technology have led to more efficient and cleaner ways of converting liquid oxygen and ethanol into mechanical energy. For example, direct injection engines and hybrid systems have been developed to improve fuel efficiency and reduce emissions. Additionally, research is ongoing to find alternative fuels that can produce even lower emissions and have a higher energy density.
