When you hear of scientific innovations at airports, they're usually trying to offset the environmental cost of such a necessary and long-haul mode of transportation.
If you think sonic booms from supersonic aircraft are a nuisance, wait until the sky is full of planes propelled by up-scaled versions of this interesting but deafening audio resonance engine. Gran…
The research study “Sound Energy Harvesting and Converting Electricity (SEHCE)” aims to create a better and easier way of producing another source of clean and renewable energy through sound.
Projects that have adapted existing infrastructure, from power generation to transportation, are demonstrating the potential of ammonia as a low- or no-emission fuel.
Humans depend on fossil fuels as their primary energy source, especially in transportation. However, fossil fuels are both unsustainable and unsafe, serving as the largest source of greenhouse gas emissions. Researchers in China have demonstrated a prototype device that uses microwave air plasmas fo... Read more
MIT engineers have flown the first silent, fuel-free “ion plane.” The light aircraft is the first plane to fly with no propellers, turbine blades, or other moving parts.
Everyone is used to perceiving ion engines as science fiction items. But they have been successfully operating in space for 50 years. So why haven’t they replaced chemical ones yet?
I came across an article about a Canadian startup that has developed a thermoacoustic engine, which utilizes sound to enhance energy efficiency.

Boeing filed a patent to generate electricity from jet engine sounds some years back.
Someone has already created an experimental engine that generates thrust from sound.
Check out this acoustic engine that harnesses sound waves.
It is possible! Sound is an energy that can be converted into mechanical or even electrical energy.
Toyota has developed an ammonia-powered engine that could revolutionize the transportation industry.
Ammonia combustion engines have a high potential for a carbon-free future in transportation.
Ammonia combustion engines are being tested for use in the shipping industry.
Ion propulsion can also be a revolutionary technology for powering cargo drones.
Ion propulsion technology, if ever realized, could end the reliance on fossil fuels and transform the travel industry.
Check this out: MIT engineers have already designed and tested an ion propulsion engine on an aircraft!
