This Is So Important. 

Do you see it?

i want to know what bears think sometimes

Copenhagen - Denmark (by Al Case) 

I hate how everyone seems to have such high expectations for me, but the second I want something a little out of the ordinary for my life they act like I've lost my mind....

Sigh.

Can someone tell me

Why almost every wc fan on Tumblr is cheering on Croatia?? Like in general? Not just because their playing against Russia.

The smallest things will ruin the days of the people who have the most in life...

And yet, for the people with the least in life, it is the small things that will make their day.

Engineers fly first-ever plane with no moving parts

Since the first airplane took flight over 100 years ago, virtually every aircraft in the sky has flown with the help of moving parts such as propellers, turbine blades, and fans, which are powered by the combustion of fossil fuels or by battery packs that produce a persistent, whining buzz.

Now MIT engineers have built and flown the first-ever plane with no moving parts. Instead of propellers or turbines, the light aircraft is powered by an “ionic wind” – a silent but mighty flow of ions that is produced aboard the plane, and that generates enough thrust to propel the plane over a sustained, steady flight.

Unlike turbine-powered planes, the aircraft does not depend on fossil fuels to fly. And unlike propeller-driven drones, the new design is completely silent.

“This is the first-ever sustained flight of a plane with no moving parts in the propulsion system,” says Steven Barrett, associate professor of aeronautics and astronautics at MIT. “This has potentially opened new and unexplored possibilities for aircraft which are quieter, mechanically simpler, and do not emit combustion emissions.”

He expects that in the near-term, such ion wind propulsion systems could be used to fly less noisy drones. Further out, he envisions ion propulsion paired with more conventional combustion systems to create more fuel-efficient, hybrid passenger planes and other large aircraft.

Barrett and his team at MIT have published their results in the journal Nature.
