Air ray, it banks and loops incredably but the general stability of it does act like a balloon, perhaps it’s just the medium of travel it is in and can’t be helped. Either way it’s still a wonderful sight.
“The thorny devil, a tiny highly specialised lizard from the central Australian desert which lives entirely on ants has each scale enlarged and drawn out to a point in the centre. Few birds could relish such a thorny mouthful and to that extent, they must be a very effective defence, but the shape of the scales also serves another and most unusual function. Each is scored with very thin grooves radiating from the central peak. During cold nights, dew condenses on them and is drawn by capillary action along the grooves and eventually down to the tiny creature’s mouth.” (Attenborough 1979:164)
Essentially it is what it looks like. A helium balloon able to ‘swim’ through the air like a jellyfish. The official version: -
Luft ist das Element von AirJelly. Die ferngesteuerte Qualle AirJelly schwimmt nicht durch Wasser wie AquaJelly, sondern gleitet förmlich dank ihres zentralen elektrischen Antriebs und einer intelligenten, adaptiven Mechanik durch das Luftmeer. Denn AirJelly besteht aus einem mit Helium gefüllten Ballonett.
Als einzige Energiequelle dienen AirJelly zwei Lithium-Ionen-Polymer-Akkus, an die der zentrale elektrische Antrieb angeschlossen ist. Dieser überträgt die Kraft auf ein Kegelrad und anschließend nacheinander auf acht Stirnräder, die über Kurbeln die acht Tentakel der Qualle bewegen. Jedes Tentakel ist als Struktur mit dem Fin Ray Effect® ausgebildet. Der Antrieb eines Ballons durch eine peristaltische Bewegung ist bis jetzt in der Luftfahrtgeschichte nicht bekannt. AirJelly ist das erste Indoor-Flugobjekt mit peristaltischem Antrieb. Die Qualle bewegt sich dank dieses neuen Antriebskonzepts, ihres auf dem Rückstoßprinzip basierenden Antriebs, sanft durch die Luft.
“The device bears no resemblance to Mother Nature’s counterparts on oaks, maples and other green plants, which scientists have used as the model for their efforts to develop this new genre of solar cells. About the shape of a poker card but thinner, the device is fashioned from silicon, electronics and catalysts, substances that accelerate chemical reactions that otherwise would not occur, or would run slowly. Placed in a single gallon of water in a bright sunlight, the device could produce enough electricity to supply a house in a developing country with electricity for a day.” ( Bernstein, M. Woods, M. 2011)
It does so by splitting water into its two components, hydrogen and oxygen. This is not the first example of photosynthesis being created before but it is the first practical one, before it was created using expensive metals that were fragile and unstable, created a decade ago by John Turner. It barely lasted a day. Nocera’s new leaf could operate continuously for at least 45 hours without a drop in activity.
The reason for this new found performance is due to powerful new, inexpensive catalysts made of nickel and cobalt that can split water into components, hydrogen and oxygen, under simple conditions. Nocera’s leaf is about 10 times more efficient at carrying out photosynthesis than a natural leaf. He has said that he is working on improving that and can make it even more efficient.
“Nature is powered by photosynthesis, and I think that the future world will be powered by photosynthesis as well in the form of this artificial leaf,” said Nocera, a chemist at Massachusetts Institute of Technology in Cambridge, Mass
Talented and dedicated engineers spent countless hours designing Japan’s rail system to be one of the world’s most efficient. Could have just asked a slime mold.
Artificial intelligence is usually pursued through computer science, but biotech systems like Warwick’s raise the possibility that cybernetics may be a quicker route to success. A step further towards organic circuits, organic circuits will be faster than our current proccessors as the electricty in organic matter is measured in near light speed. I’ll find out what I can if organic circuits.
This sharkskin-mimicking paint was developed using a sophisticated formula developed by the IFAM researchers. Not only is the paint long-lasting, but can withstand intense UV radiation, temperature changes, and mechanical loads due to the integration of specific nanoparticles into the formula. Instead of applying the paint directly to a ship or airplane’s shell, the paint is applied with the use of a stencil that causes tiny ridges to be formed all over the painted surface. Once the surface is treated with UV radiation to harden the paint, the stencil is removed and vessel’s exterior is coated with ridges that reduce drag, increasing fuel efficiency significantly.
It’s also been discovered that shark scales are such a shape that bacteria can not land on it and it being researched to be used in hospital environments.
Japanese scientist has created an almost painless hypodermic needle, inspired by the mosquito’s probosc.
Nanocoture, I perspective on fashion in the future as it looks on the nano scale. Nature can be disected and looked at in the nanoscale to find out it’s tiny secrets and on the holistic scale to see how it all reacts to each other in the ecosystem. As should society.
