We can produce electricity from atmospheric pressure difference

Wind turbines do this all the time

There is another interesting method to use this

i have an idea of generating electricity...
inside vacuum there is no opposite pressure.a vacuum container is taken with a lubricated end.the end is closed with a long and light weight rod.just below the rod on the bottom surface of the container,a spring is tightly paced .So, because of atmospheric the rod is sucked inside and the spring contracts and pushes the rod to its same position.then energy can be generated by the action of spring...

Pressure alone will not generate Electricity. To get energy, you need a force (or some pressure) and you need motion (or a flow of fluid).
Your suggested system would work for one shot only. You would then need to pull the rod out again (supplying your own energy) and start again. The atmosphere would only be acting like a spring, to store energy - and not acting as a source of energy.

The Energy Tower and, of course, wind turbines, work because there is a net movement of air, along with a pressure difference. A vital difference there.

Yes, it is possible to generate electricity from atmospheric pressure. One method is through the use of a device called a piezoelectric generator. This device converts mechanical pressure into electrical energy through the use of piezoelectric materials, which produce an electric charge when subjected to pressure. This technology has been used in various applications such as in sensors and energy harvesting systems.

Another method is through the use of a device called an air pressure turbine. This device uses the force of air pressure to rotate a turbine, which then generates electricity through a connected generator. This technology is still in its early stages of development, but it has shown potential for generating electricity from the constant atmospheric pressure.

There are also ongoing research and development in the field of energy harvesting from atmospheric pressure changes, such as using vibrating membranes or flexible materials that can convert small pressure changes into electrical energy.

Overall, while it is possible to generate electricity from atmospheric pressure, the efficiency and feasibility of these methods are still being explored and improved upon. Further research and development in this area could potentially lead to more sustainable and renewable energy sources.
