Exclusive Most small commercial drones have limited flight times because of heavy batteries. But XAir's can fly for hours by coasting on wind currents.
Aircraft safety is a hot topic these days, with Federal Aviation Administration investigators looking into door seals at Boeing, aircraft slides flying off mid air and engine failures plaguing several planes in recent months. But what happens if the power in your plane actually does go out? That’s... 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.
Wind energy is not reliable enough to be used as the sole power source for an aircraft. Not to mention, adding wind turbines to an aircraft would increase the drag, leading to more problems.
Swedish start-up Minesto has been for years trying to float the idea of having underwater turbines that generate power for use on-shore. These would be anchored to the seafloor by a long tether and…
French company Airseas has developed the Seawing, a kite to help propel cargo ships, which it says could cut their carbon emissions by an average of 20%.
Michelin has developed a new kind of sail for cargo ships, one of a number of sail innovations that could help the industry to reduce carbon emissions.
With Amazon, Ikea, Unilever and major movers of ocean cargo seeking ways to meet net-zero carbon goals, the oldest source of ship power, wind, may be back.
I found this startup that makes drones powered by wind power.
Glider planes can also fly with the wind, without any engines.
Some planes are fitted with wind turbines to generate emergency power in case of engine failure.
These MIT researchers have done it, but using ion wind propulsion.

We could also install wind turbines in high-flying kites to increase efficiency.
This kite can harness wind energy to power maritime vessels, reducing their reliance on fossil fuels.

Kites can fly higher than wind turbines, thus harnessing more energy.
Check out these inflatable wind sails that might soon start appearing on ships.

Some cargo ships do actually use sails to reduce fuel consumption!
Wind propulsion is the answer to the ever-worsening carbon emission crisis in the shipping industry.
Modern windmill ships are the future of the maritime industry; they can make sea travel greener and much cheaper.
There are more green options for the maritime industry besides wind, such as liquid natural gas, electricity, liquid hydrogen, methanol, and solar power.

There are wind turbines that can turn your traditional boat green with a few modifications
Wind power might be the only viable solution to making the maritime industry green and reducing greenhouse emissions.
Before the advent of carbon-based fuels, people used winds to sail across the world, so why not continue using them?
