The heat can be used to boost the thermal expansion of the liquid air.
Liquid air could also help store surplus energy generated by wind and solar.
He said he believed his liquid air engine would prevail against other storage technologies because it did not rely on potentially scarce materials for batteries.
Like the recently reported "liquid air" approach, Air Fuel Synthesis wants to use renewable energy which may come when there is no consumer demand for it.
While playing some slow-motion video of liquid flying through the air throughout the event, it was impossible to take our eyes off the thing.
The A3 e-tron sports two Sanyo liquid-and-air-cooled battery packs, one under the trunk area and the other in a T-shape under the passenger compartment.

Doshi has recruited engineers from Miami and Atlanta for his venture, but he got some key technology nearby: To perfect the design of a filter, he got computational engineers at the SimCenter at the University of Tennessee at Chattanooga to model thousands of air- and liquid-flow variables.
They fill the container with pure air made by evaporating liquid nitrogen and liquid oxygen, and add water vapour and some trace gases.
In addition to all this, the Genesis uses liquid cooling around the motherboard, and an air-based system on the video cards.

To do that they need not one but two energy-hogging air chillers, one to make liquid oxygen and another to remove CO 2 from the flue gases.
To simulate the atmosphere, they have built a special cloud chamber of their own, with the air manufactured from scratch, using liquid nitrogen and oxygen together with precise amounts of trace compounds, including sulphuric acid and ammonia.
Using physics similar to that of evaporative swamp coolers, the warm air from the spray dryer cools the liquid insulin as it evaporates.
The Hailstorm II pairs an advanced liquid cooling system with a blustery current of cold air driven by three front intake fans and a large rear exhaust fan.

When water velocity is high, the pressure within the liquid drops to below the vapour pressure of water, allowing tiny air bubbles to expand.
The consequent condensation of the water vapour it is carrying heats the air further (the change of state from gas to liquid sheds latent heat), causing it to continue rising.
Water is much more efficient than air at absorbing heat and so even with tiny amounts of liquid flowing through the system the researchers saw a significant effect.
The crisis began in August when 528 cubic metres (116, 000 gallons) of toxic liquid unloaded from a ship called the Proba Koala were dumped in 11 open-air sites in residential areas around the commercial capital, Abidjan.
