Perhaps the acronym UFO would be more usefully applied to “unusual flying objects” these days, since there seem to be so many of them around. A few weeks ago, Raw Story reported on a 45-foot paper airplane. Today’s craft may be no more practical, but it appears far more effective at getting about under its own power.
The SmartInversion device was designed by engineers at the German firm Festo, and the note which accompanies their video of it in operation explains, “SmartInversion is a helium-filled flying object that moves through the air by turning inside-out. This constant, rhythmically pulsating movement is known as inversion and gives the flight model its name.”
New Scientist explains in greater detail that “the flying object itself is made up of six identical prisms filled with helium, held together by a carbon-fibre framework. Three motors drive the motion coordinated by a tiny onboard computer, pre-programmed to replicate the inversion sequence. Using a smartphone, a person on the ground can guide the object around a room,”
“The firm still hasn’t come up with a specific use for inversion-driven propulsion,” the magazine adds. “The mechanics of automated systems are typically based on rotational or linear motion to drive, for example, motors or grippers, but inversion is seldom used in designs. The company has now launched a competition challenging students in Germany to suggest a functional idea that could be implemented in an industrial environment. ”

Ex-Bush aide says Trump falls back on racism because he’s losing his mind: ‘Take him to Walter Reed for a full medical’
MSNBC contributor Elise Jordan said President Donald Trump was stuck peddling racism because he's losing his mental faculties.
The former speechwriter and National Security Council staffer in George W. Bush's administration said Trump's attack on four Democratic congresswomen betrayed his inherent racism, and showed that he's mentally diminished.
"I think you're being a little bit too charitable regarding Donald Trump having an actual strategy in the first place," Jordan told "Morning Joe" host Joe Scarborough. "I think that this is who he is -- he's racist."
"You have seen it, you know, his entire career," she continued, "whether it's calling for five young black men who are innocent to be executed. you see it in his comments consistently throughout the course of his campaign wanting to ban an entire religion from entering the country, and just this week the horrible remarks that, you know, an elected official -- elected by her fellow countrymen and women should be grateful to be in the country and should leave otherwise."
MSNBC’s Morning Joe drops the hammer on Trump’s ‘mob’: A ‘new level of racism’
MSNBC's Joe Scarborough said President Donald Trump believes the four Democratic congresswomen he's been attacking aren't capable of being fully American because they're not white.
The "Morning Joe" host said Trump's recent attacks on those first-year lawmakers had followed a familiar pattern, but Scarborough warned the president had taken those racist provocations to a new level by suggesting that people of color aren't capable of loving their country.
"They're not white," Scarborough said. "Clearly, (he) is suggesting (because) they're not white, they're foreign, even though they're not, and also, very interesting in that press conference -- that presser when the president said, 'They're just lucky to be where they are.' That's Donald Trump saying, you know what? Given that they're women and they're from Somalia or from wherever, Detroit, from Cincinnati, regardless, they're just lucky to be where they are."
