“The proactive ship flourishing in the air : The semi-rigid not pressurised airship stretches vertically around an arborescent spine that air-dynamically twists on more than 400 meters high and 180 meters of diameter. Forming a big flower ready to open, the spaces divide in cross under the shape of petals that welcome respectively the main sectors of activities: housing, offices, scientific laboratories and entertainment. The stem around the one these functional petals structure themselves, welcome the vertical circulations, the technical premises and the goods warehouses for the freight. These 4 inhabited spaces are included between 4 great bubbles inflated with bio-hydrogen, a renewable energy. These bubbles are made with a rigid hull in light alloy shaped with twisted longitudinal beams linked together by wide sinusoidal rings. Every end is finished by a cone, and the one at the bottom, the most sharpened one carries the stabilizers and the rudders of deepness and of direction. This framework is covered by a double layer of waterproof, fireproof, glazed canvas to reduce the resistance to advancement. The in-between is divided into slices in which there are small balloons full of helium. The helium mattress in periphery enables to protect the balloons of bio-hydrogen and helium, the remaining 30% are provided by the aerodynamic of the airship twisted fuselage with the speed, as for an airplane. This type of airship is of course heavier than a flexible aerostat of same cubing because of the weight of the structure, but it can reach higher speeds, thanks to the solidity of its hull in titan, and carry more tons thanks to the ability to build always bigger layers (10000 m3 in 1900, 70 000 m3 in 1924 and 200 000m3 in 1938, 250 000 m3 in 2010). What distinguishes also such a machine from classical aircrafts from the past is that this one is heavier than the air and flies thanks to the Archimedes’ thrust (that does every balloon or aircraft), to helixes or at its subtle twisted aerodynamic that enables to reduce the oscillations of the limited layer. The fact that it is heavier than the air enables actually descents faster without having especially to eject gas. Moreover, the sustentation is based on the compression and the decompression of the biogas. Hydrogenase can thus be lighter or heavier according to the wished needs and the height. In order to build a proactive airship with positive energy, we also have integrated all the renewable energies. Actually, whereas the inflatable bubbles are glue-backed with flexible photovoltaic cells the four wings of the vessel are each of them inlayed with turbo-propellers with recuperation of energy. These 20 wind propellers are articulated around orbital rings which enable them to go from the horizontal position at the take-off to the vertical position assuring the vessel a navigation speed of 175km/h. The inhabited spaces integrate by steps vegetable gardens photopurifyng the used waters, the biomasses damaging the organic waters and loaded fuel cells. Nothing is lost, everything is recycled and transformed! On top of absorbing the solar energy, this flying castle draws its inspiration from the biomimicry technologies and is built in lighter and more resistant composite materials (fibreglass and carbon fibre) in order to reduce the weight of its structure at the maximum. The fitting is thus self cleaning, in nanostructured glass inspired from the lotus leave that does not get wet. The vessel is thus made of « intelligent layers » avoiding for example the accumulation of ice or snow and « self-separable ceramics » offering a bigger resistance to the split and that fill the cracks. This bionic coating draws also its inspiration from shark skin that enables without being toxic to avoid the adhesion of bacteria whereas the four wings present irregularities of surface, as the finely beaded whale fins do, in order to reduce the turbulences. The green industry meets thus through this bionic prototype the expectations of the consumption, the always more demanding antipollution regulation and the rarefaction of resources. The floating organic farm on seas and oceans: The floating farm is a true organic purifying station composed of 4 carbon wells in which the green seaweeds recycle our carbonated waste brought by ships. This is directly dedicated to feed organically in biohydrogen the proactive airship. It replaces thus the petrol station as the runway for traditional airplanes and looks like a weaving of fine amphibian laces! Actually, it sets up as much underneath as on top of the sea surface and respects the quadripartite sharing out in petals of the whole Hydrogenase project. Continuing the 4 wings of the pneumatic tower, 4 great arches structure this circular platform and distribute vertically all the levels of the central ring inhabited by the scientists. At the surface, these arches are covered by thermal and photovoltaic solar shields whereas under the water they are set with 32 hydro-turbines transforming the tidal energy of the sea streams into electricity. Energically self-sufficient, this farm organises on a radiant plan, the seaweed bioreactors exposed to the zenith sun under the lenticular accelerators for a better photochemical output. The whole set forms four gardens dedicated to the accelerated photosynthesis where we access through marinas setting the exchanges between this true new floating city and the surrounding coasts. On top of producing clean energy, this floating purifying station is also an incredible observatory of the sea fauna and flora that fight for the protection of ecosystems and for the revitalization of the beds of corals and of endangered species. It is a true cleaner of seas and oceans by skimming and damaging as main nutrient the floating waste banks of our energy-consuming civilisation. Hydrogenase is thus a project of environmental resiliency that will enable to invent a clean mobility according to a « cradle to cradle » cycle respecting our planet by assuring also the technological evolution of the human adventure ! As biotechnological prototype, it aims at being the symbiosis of men actions and their positive impacts on the nature. By imitating the processes of natural ecosystems, it deals with reinventing the industrial, town-planning and architectural processes to produce clean solutions and create an industry where everything is reused, either back to the ground under the shape of not toxic « organic nutrients », or back to the industry under the shape of “technical nutrients” able to be indefinitely recycled.” http://www.dezeen.com/2010/05/07/hydrogenase-by-vincent-callebaut/
