Scientists Develop Car That Runs On Liquid Air

The video discusses liquid air as a potential green energy source. Liquid air is created by cooling atmospheric gas to extremely low temperatures and can be used to power engines and store energy. It is considered more practical than electric cars and is being refined by engineers. Liquid air can store excess electricity and release it when needed, offering a scalable solution for the national grid. The technology has significant economic potential and could reduce fuel prices, with British engineering leading the way in its development.

What is the primary advantage of liquid air over electric cars according to the inventor?

• It has a higher top speed.

• It can be refilled quickly like a petrol engine.

• It requires less maintenance.

• It is cheaper to produce.

How does liquid air contribute to energy storage?

• By using wind energy to freeze air.

• By storing excess electricity as liquid air.

• By generating electricity directly from air.

• By converting solar energy into liquid form.

What is a key benefit of using liquid air for the national electricity grid?

• It increases the efficiency of solar panels.

• It eliminates the need for batteries.

• It reduces the need for new power stations.

• It decreases the cost of wind turbines.

Why is the Institution of Mechanical Engineers interested in liquid air technology?

• It is a well-established technology.

• It is the only green technology available.

• It has potential for global sales.

• It is cheaper than other technologies.

What economic impact could liquid air technology have?

• Boost to the British economy.

• Reduction in global engineering jobs.

• Decrease in electricity demand.

• Increase in fuel prices.
