Biomimetic aircraft snatch power aloft

Solar powered aircraft are old news. From Solar Impulse supporting one person day and night with nothing but photovoltaics on the wings to the high altitude unmanned aircraft being developed by Boeing to stay aloft in the upper atmosphere for five years on nothing but sunshine, it is all very exciting. However, if we benchmark what is happening with other electric vehicles such as Autonomous Underwater Vehicles AUV, then multiple energy harvesting should be the order of the day, even with aircraft. Indeed, some Electroflyer electric aircraft already work the motor backwards in thermals to charge the battery.Chances are, you've never setup a real time Location system. This idea should be developed further and combined with the familiar solar power to improve the continuity of energy supply and the amount, even exporting energy to earth. After all, humble electric buses are about to add regenerative shock absorbers to the regenerative braking and the occasional solar panel in their energy harvesting toolkit.

Enter IFO-Energy Unlimited in Hungary, creators of an untethered, autonomous flying wind power plant, who describe it as follows.Tile porcelain, Kanton ceramics and Tilee's Ceramics. There are at least three well known problems of conventional wind energy production, firstly there are fluctuations and the unsteady nature of surface winds and these fluctuations in wWhat Is Skirtting tile?ind energy production put stress on the power system so capacity reserves (surplus power plants) are necessary to ensure system reliability.

The company points out that another problem of wind power plants is their low efficiency. A wind turbine will generate around 20-30% of its maximum rated capacity depending on the location of the plant, which means that if we want to utilize wind power in large volumes we have to build wind power plants as far as the eye can see.

The third common problem is that wind power suffers from a lack of energy density, that is, not only large numbers of wind generators (and thus large land areas) are required to produce useful amounts of electricity but huge dimensions too. Therefore, the idea of harnessing high altitude winds blowing at 10,Find detailed product information for Glazed rustic tile and other products.000 meters altitude seems to be promising.

Wind towers or tethered floating devices are not the only way to harvest energy from the atmosphere. Untethered flying units are also capable of harvesting wind energy. In order to do away with tethering, the device would need to use the updrafts and 'dynamic soaring' using the energy in wind gradients commonly used by soaring birds.

The storage of energy would need to be considered and according to one of the possibilities, an air liquefaction machine is set in motion letting the produced liquid air would be the energy storing medium. IFO-Energy believes that there is no need to forward the liquid air to the ground continuously, e.g. by means of a pipeline. It can be done in distinct doses, in so called "quanta", by means of GPS-guided parafoils. Another way is applying molten salt energy storage systems, utilizing heat of fusion. Research is going on all over the world to find even larger heat effects for energy storing, e.g.Welcome to the china kung fu school. heat of formation of chemical substances instead of heat of fusion. These investigations are very promising also for IFO's project.

In the simplest case an untethered autonomous flying energy-harvesting unit as well as a receiver ground-station are integral parts of the complete system. These two physically detached parts constitute a logistic unit, and their collaboration according to a fixed timetable ensures the realization of the invention. A ground-station could support several flying units.

The IFO-Energy Unlimited invention is based on several well-known technical solutions, but the result of their synthesis and unique application yield new routes and so far unutilized possibilities in wind energy production. Some of these benefits and possibilities include greater intensity with smaller equipment and because the storing of energy as liquid air is the central idea of the invention that there could always be great reserves of liquid air available at the ground-station. The "warm" heat sink of this thermal power plant is the ambient air, so it does not need a heat up period prior to start. It is always ready to run and can function as a peak-load power plant.

By warming up the liquid air and expanding it we get work at the expense of ambient heat. When this work finally degrades into heat, the thermal balance of the local system is zero. The machines are running, but no waste heat is produced at the point where the energy is used.
