The only problem is, previous studies estimated the warp drive would require a minimum amount of energy about equal to the mass-energy of the planet Jupiter.
But recently White calculated what would happen if the shape of the ring encircling the spacecraft was adjusted into more of a rounded donut, as opposed to a flat ring. He found in that case, the warp drive could be powered by a mass about the size of a spacecraft like the Voyager 1 probe NASA launched in 1977.
Donut power!

Thanks Rob, for explaining the Hole thing.

We'll never know how scientists got along without donuts, because they never had to. For example...
WOW, the first donut in history!!! It seems it was a temple to praise the Donut Goddesses!

Donuts are descriptive of most everything, cosmic object orbits (in general), life we go round in circles, the view port iris, race tracks, particle accelerators, the list is not endless…

there are fire tornados, I didn't know that! I experienced only dust whirlwinds when I was in Turkey.
I saw this video when I read a Swedish newspaper online, and the video is apparently from Swedish television. That's why there is no English speaker here, explaining what we see. But what has happened is that foam from the sea has swamped the Aberdeen seafront. The weather had been bad for days in Aberdeen when this happened, with strong winds from the sea that hadn't let up for a long time. Organic material in the sea water, probably plankton, was churned by the winds and mixed with water into incredible amounts of thick foam, which was then blown up along the seafront of Aberdeen, covering streets, gardens, playgrounds etcetera in this thick whitish goo.
<<Sea foam, ocean foam, beach foam, or spume is a type of foam created by the agitation of seawater, particularly when it contains higher concentrations of dissolved organic matter (including proteins, lignins, and lipids) derived from sources such as the offshore breakdown of algal blooms. These compounds can act as surfactants or foaming agents. As the seawater is churned by breaking waves in the surf zone adjacent to the shore, the presence of these surfactants under these turbulent conditions traps air, forming persistent bubbles which stick to each other through surface tension. Due to its low density and persistence, foam can be blown by strong on-shore winds from the beachface inland. Where polluted stormwater from rivers or drains discharges to the coast, sea foam formed on adjacent beaches can be polluted with viruses and other contaminants, and may have an unpleasant odour. If crude oil discharged from tankers at sea, or motor oil, sewage and detergents from polluted stormwater are present, the resulting sea foam is even more persistent, and can have a chocolate mousse texture. If the foam forms from the breakdown of a harmful algal bloom (including those caused by some dinoflagellates and cyanobacteria), direct contact with the foam, or inhalation of aerosols derived the foam as it dries, can cause skin irritations or other respiratory discomfort. On rare occasions large amounts of sea foam up to several metres thick can accumulate at the coast and constitute a physical hazard to beach users, through concealing large rocks and voids, storm debris and, in northern New South Wales, even sea snakes.>>

Many years ago, when I was still wooing my intended and therefore had to display chivalry, we two were walking along the shoreline in northern New Brunswick with their family dog, a German Shephard named Lady. (There is no credible theory as to how she got her name. Certainly it had nothing to do with lady-like behaviour.) As we approached a spot where we usually had to jump a few feet down off a rock outcrop to a stony beach, Lady led the way straight out into a pile of sea foam which had been funneled in there by the rocks, to a depth of about 5 feet (152.4 cm.)
We stood for a few moments laughing at the hump of foam moving around barking, thinking Lady would work her way out of it. But no, she started to head towards the water, so chivalry in hand I jumped in after her and waded out to where I could reach down to pick her up. Picture me almost neck deep in foam at that point. Picture me reaching down to pick up a dog. Picture my long-haired bearded visage with sea foam decoration.
When we returned home, Lady, me and my formerly best coat all got hosed down, which more or less cleaned us up. Lady thought it was a fine afternoon walk gone slightly awry. My future wife thought it was even funnier when I followed Lady into the foam. I maintained a dignified silence through dinner as the tale was retold, though I recall that the family accorded Lady and I more than the usual amount of elbow room. Sea foam smells.

Thanks BMone23 for all the fire pillars, the video clip from Hawaii looks extremely dangerous!
And for the last version:
Not funny...(credit Moses)
Rob, did you get after rescuing Lady a ? Is that why you love doghnuts?!

So this means the last option is to amputate hands and feet?!
But there are the teeth which is also used to indentify...hmmm ok, extract all real teeth and implant false teeth.
And Iris identification is hard to manipulate...ok eyeballs amputation and put glass eyes in...
DNA is the hardest...if you have a twin...blame him/her

DNA might present a problem though in people that have Blood DNA tested and have had a Bone Marrow transplant. Their Bloodcell DNA might resemble that of the donor
