New forms of flying machines... The internal used in and is a 100 year old . It combines gas, air and and fire to make an explosion in a small chamber. That controlled explosion moves a bunch of other parts eventually moving wheels or a .
In a liter of liquid fuel there is 100% energy. Do you know what percentage of that energy ends up being used to move the wheels? Just 20%. The rest of the energy is lost through heat and transmission of the energy. The combustion engine is .
motors and batteries are a new technology that is being developed for decades now. are more directly connected to wheels or propellers. They also have very few moving parts.
What percentage of the power in ends up being used to move wheels or a propeller? About 80%! The difference in efficiency between combustion engines and electric motors and batteries is a classic representation of .
Batteries are the major bottleneck at this time. The density of a is not yet equal to the of liquid fuel. However, battery tech is improving at a steady rate and will surpass that of liquid fuel.
Now imagine if future batteries were 2x or 10x of their current power density. We would have a large amount of power in a very small amount of space and weight. This would enable us to develop new forms of machines that we can’t make with our current technology.
is a company in that is developing an electrically powered drone for people. They’re testing in Dubai and Nevada.
Researchers in are developing their own version.
is a company that is one of the leaders in electrically powered aircraft. They’ve got a deal in the works with a company.
has been working on a new kind of vertical take off and landing vehicle.
makes jet engines. Looks like they don’t want to be “Kodaked” so they’re getting in the game.. is looking into electric aircraft as another form of . in too.
is just getting started..
