Google hot air balloon energy storage

How do balloons store energy?

Balloons are elastic and store potential energy when they are filled with air. When the air is released, the potential energy is converted into the energy of motion, which is also known as kinetic energy. This is the energy you see when the car is propelled forward.

How do balloons work?

The compressed air is cooled before it shoots down a tube and out to the massive balloons. Just like blowing up a balloon on land, the air fills up the balloons in the ocean, but because of the many feet of water pushing down, the air inside compresses. The deeper the balloons, the more air they can hold.

Can a tethered hot air balloon fuel a solar powered reciprocating engine?

This paper describes a solar powered reciprocating engine that is powered by hot air from a tethered hot air balloon. The balloon is fueled by hot air from a glazed collector. The basic theory of the balloon engine is derived and used to predict the performance of engines in the 10kW to 1MW range.

How does a hot air balloon engine work?

In a hot air balloon engine, hot air is raised in a balloon. As the balloon rises, it drives a cable which, in turn, drives an electric generator.

How does a solar balloon produce work?

In a solar balloon, absorption of heat from sunbeams modifies the density of an air filled balloon and causes its ascent to produce work. Different schemes have been proposed in the literature where the use of gravitation has been coupled to heat sources to create heat engines.

Could Hydrostor's underwater balloons make energy storage possible?

Hydrostor's underwater balloons could at least make the energy storage method possible in communities near the ocean or deep lakes. Sitting under roughly 180 feet of water, Hydrostor’s six test balloons measure 29.5 feet tall and 16.4 feet wide.
