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.
