Hello I am Lucien Gambarota and I am the owner of the group
www.motorwavegroup.com and Motorwind.
I noticed traffic on my site from econologie.com and I would like to provide some explanations to the questions asked.
A) why is the system not directional ?.
in most countries of the planet the Wind comes from the North in Winter and from the South in summer except special geographic configuration.
this is considered to be the case at least 80% of the time.
the fact of not having a directional system makes it possible to gain simplicity of manufacture and therefore to reduce the weight significantly and therefore the cost.
the micro turbines have a design which allows to redirect the wind direction so even if the wind is not perpandicular the turbines work almost as well.
in terms of philosophy either we orient the turbines facing the wind
or we redirect the wind.
a microturbine is symmetrical which makes it work
with winds from the opposite direction and on each side it can redirect the wind by almost 60 degrees.
so with wind NE or N or NW or SE or S or SW it works.
occasional E or W winds are too expensive to recover.
the system is therefore not perfect but it makes it possible to recover winds of very low speed and especially it is practically the only system which is usable in urban environment.
in terms of power: the power of a turbine or wind turbine
depends only on the collection surface.
on an equal surface the power generated is the same as for a conventional wind turbine, but the difference is that it takes about 10m / s for a conventional wind turbine to start while a microturbine starts at 0.8m / s and that at 25m / s a wind turbine must be stopped
whereas a micro turbine has no stopping speed.
all our installations produced electricity during the last typhoon in Hong Kong with winds of 110 km / h.
in a standard city the winds are on average 5m / s and at this speed we generate approx 15 W / m2 of microturbines.
if you want 1kW you have to install around 65 m2 of turbines.
which would be equivalent to a wind turbine of 9 meters in diameter.
and knowing that this 9 meter wind turbine would barely produce 20% of the electricity produced by micro turbines.
Above all, microturbines should not be considered as a replacement for wind turbines, but rather as a new source of electricity that can be used where the wind turbines do not have access.
there are almost 1 billion people who do not have access to electricity on this planet and who cannot afford a wind turbine but who can spend a few dollars on micro turbines.
for those interested, a pilot installation will be set up in France in the Rhone Alpe region within a few weeks.
Good day to all and I am at your disposal for further information.
