The Switch Knife of Flying Cars.

Incredible flying car with folding wings to offer freedom from traffic jams

Hoversurf, the Russian company behind the notorious "hoverbike", has unveiled its latest invention - a flying car with folding wings that can fit into parking spaces and promises freedom from traffic jams. Dubbed the ' Formula Project', the vertical take-off and landing (VTOL) vehicle seats up to five people, and is powered by 52 turbine propulsion units and 48 electric thrusters.

 From article, (Hoversurf, the Russian company behind the notorious "hoverbike", has unveiled its latest invention - a flying car with folding wings that can fit into parking spaces and promises freedom from traffic jams.

Dubbed the 'Formula Project', the vertical take-off and landing (VTOL) vehicle seats up to five people, and is powered by 52 turbine propulsion units and 48 electric thrusters.

Its futuristic body is formed from 3D printed carbon fibre and metals, and it has fold-away wings, so it can fit into a normal car parking space or garage.

It navigates using 3D vision technology, and is designed to be as aerodynamic as possible, with a good weight to strength ratio.

Hoversurf says that, unlike rival flying car concepts, its Formula Project vehicle is "ready to use in real world".

"Do you know the problem of all projects of flying cars? They are all made for the future. None of them you can not use today. Impossible to parked at the store or put in a garage," the company says on its website.

"Formula - is created for the present day. You will not notice how quickly it will become a part of your life - conveniently and safely.")

Me, "There are going to be those that laugh, But, once flying cars, like these, become more readily seen, in the air, transporting people, laughing will turn into actual use and ownership."

Faster trips to Mars, or centrifugal force, will be needed to prevent bone and muscle loss for future astronauts.

Humans traveling to Mars may soon be possible. Whether they can survive the trip is another story

Bone mineralization is one of those lack-of-gravity problems. For each month in space, Logan says the human body loses 1 percent of its bone mass. And, once back on Earth, the bones don't grow back. "I'm not trying to throw cold water on the idea of going to Mars.

 From article, (Logan spent 20 years helping diagnose and treat NASA's astronauts. He said the main obstacle to sending humans to Mars is what he calls "the gravity prescription."

He said: "We know what Earth's gravity – one G for 24 hours a day – does. And we know that zero gravity, after four months, begins serious health deterioration."

Bone mineralization is one of those lack-of-gravity problems. For each month in space, Logan says the human body loses 1 percent of its bone mass. And, once back on Earth, the bones don't grow back.

"I'm not trying to throw cold water on the idea of going to Mars. I want to make sure we can survive if we do go," Logan said.

He says, if putting humans on Mars is truly a near-term goal, it means studies today must focus on Martian gravity, or 0.38 Gs.

"We need to start sending more people into space if we're actually going to get somewhere, with even problems we know like the gravity prescription," he added.

The scientist also said that it is critical to use the words "outpost" and "settlement" distinctly when talking about space exploration.

"Let's stop playing fast and loose with this idea that the ISS [International Space Station] is our first settlement in space. We have a permanent presence, but with rotating crews," Logan added. "Settlement is men, women, children, over multiple generations.")

Me, "We can build spacecrafts that can go faster between Mars and Earth so lack of gravity is less of a problem on the human body. We can institute some kind of artificial gravity (Centrifugal Force) spinning a part of the space craft to simulate gravity where astronauts can spend a lot of their time. And, once we get to Mars, we weigh down our clothing, with weights so as to produce, simulated, Earth like gravity, to keep astronaut bones strong. We need to come up with ideas like this to keep the human body, that was built for Earth, to continue to function in other lower gravity, or lack of, locations."
