WHAT IS THE PHSRD's
OPTIC
PRINCIPLE ?
SYCOMOREEN
is inviting you to watch this
video of educational discovery of the PHRSD where you will see the
trapping of the direct solar rays in the set of an experience in dark
room.
.
"I
saw the desert extents illuminated by the Sun,
if everything is linked with the Earth, the Earth is linked with the
Sun, its first source of energy.
That the plants made while capturing its energy, can't Mankind
be able to do it ?
In one hour, the Sun gives to the Earth the energy consumed by all the
humanity in one year,
so much that the Earth exists, the energy of the Sun is inexhaustible.
It is only to stop to dig the
soils and to raise the look skywards... It is
only to learn to cultivate the Sun."

14/12/2008 __________________________________________________________ DO
THE CONCENTRATING SOLAR PLANTS REALLY
ENTAIL
MONEY AND EMPLOYMENT ?
Recently,
Barack Obama, new President of the USA, has forwarded a lot of studies
and diagnostics in order to relaunch the economy, and the employment in
the
USA, while facing the worrying
financial,
energizing,
(and perhaps ecological...) stakes of our World.
According to the
Experts of the Duke University"The new market for concentrating
solar power plants has potential to create numerous U.S. manufacturing
and construction jobs as U.S. companies grow and foreign
firms come to the United States.",
The following extract from their
recent report on CSP, is regarding
the National Renewable Energy Laboratory's evaluations :
" The NREL estimates that an
investment of $13 billion dollars in the installation of 4,000
MW [4
nuclear units] of CSP, as expected
based on the current and planned CSP plant development across the United States, will create 145 000 jobs in
construction and 3 000 direct permanent jobs (Stoddard and
Al., 2006). Although the majority of
the construction and operation and management jobs would
be located in the Southwest, there
will also be significant gains in manufacturing jobs,
which would likely be more widely
distributed across the country."
SYCOMOREEN
recalls that approximately
1% of the desert areas are sufficient to supply all the anthropic
energetic needs, cleanly
and nearly free, especially with its PHRSD Technology...
09/11/2008 __________________________________________________________ WHAT'S NEW
ABOUT THERMAL STORAGE RECOMMENDED BY THE PHRSD ?
In
his PHRSD
patent, set down to Paris' INPI, February 6th 2008 by SYCOMOREEN,
in
order to supply and manage the solar power which is available only
during
diurnal and sunny time for concentrating solar plants (CSP), it's
mentioned on
page n°15 :
"the hyperthermal solar traps
have the advantage to permit an
efficient
and little costly thermal
storage of big size, since
it will be sufficient to heat at about
1000°C,
with the help of a coolant fluid and pipes of thermal exchange, a
important mass
of materials with good thermal
capacity : rock, earth, sand, metals, water or specific
fluids.
These materials should be positioned in containers taking the building
principles of
the
insulating cockle. The containers will possibly be buried or
integrated in the re-raising device "
SYCOMOREEN
has an appreciably different approach : rather than to construct a
heavy rigid and little isolated structure, we propose an insulated
hollow container
so much on the radiative way (mirrors in "dolls Russians") that thermal
way (insulation by depressurized air) containing a network of
hyperthermal hoses and deformable material forhigh
temperature. It seems
more applicable to directly use the sand (extensively present
in the desert...) or the quartzic silica
(in block or in compacted powder: SiO2 is present in big quantity in
the sand) keeping its
crystalline shape until 1650°C
and whose thermal conductivity (10 W / K / m) is ten times bigger than
the one of the concrete (1 W / K / m) to have better speed of thermal
storage / unstorage.
0.5 m3 of silica (cube of 80 cm nearly full with
1300 kg of SiO2 of density 2.65, M = 60g / mol) gives a thermal capacity of 540 000 J /
°C (according to the Dulong and Petit's
law of for the mass thermal capacity of highly heated solids)
A fall of 300°C in the
stocking hyperthermal SiO2 block (for example of
1300°C to 1000°C), releases 45 kWh thermal, of
which 45% are convertible in electricity (20 electric kWh), either the average and typical
electric daily consumption of 2 French homes (400W/house)
and 55% (25 kWh thermal)
remain available for the domestic heating (possibility of electric/heat
cogeneration
through this thermal unstorage...).
24/10/2008 __________________________________________________________ COULD THE
PHRSD INTEGRATE IN THE THE DESERTEC PROJECT ?
As
it has an efficiency widely better than usual devices without solar
trapping, and it
is highly modular with small autonomous units that can be juxtaposed
and/or interconnected, the PHRSD
is a technological breaktrough to build little and big
concentrating solar plants able to bring a massive and clean
contribution in the energetic mix.
SYCOMOREEN
invites you to read the the last News
about DESERTEC whose project isn't
sufficiently promoted altough it is a key-point to solve a lot of
hazardous
and urgent issues (social, economic and ecologic), notably for the
EUropean, Middle-East and Nord-African countries (EU-MENA).
Some
american scientists have also understood the stakes to launch
a big solar plan for their country and declare : "The greatest obstacle
to implementing a renewable (...) energy system is not technology or money,
however. It
is the lack of public awareness that solar power is a practical
alternative—and one that can fuel transportation as well."

It's
about getting simultaneously :
- financial means,
- massive supply of soft water to increase the agricultural
production in dry soils while limiting the weariness of the
arable soils,
- the reduction of the worldwide poverty through a technological
economic growth, then economic,
- fuels extracted from biomass and clean energies.
Are these objectives really contradictory ? Not for the PHRSD

engines...
SOME
HYPERTHERMAL SUN ENERGY ? BUT WHAT TO DO WITH THAT ?
Extracts from Bernard
BIGOT's conference, High Commissioner to the atomic energy, (CEA, France) LYON 16/02/07
On
the short term, it is necessary to obtain a temperature of more than
1000°C to be able to double, or even to triple the present
solaro-electric output of the "thermodynamic solar path."
But
in itself, an hyperthermal source combined or not with the
production
of electricity opens a lot larger perspectives... certainly in alonger term vision.
- VARIOUS
ELECTROLYSES : obtaining
of H2, or of electropositive metals generating
in situ the H2 with water (Sodium or aluminum)
-
AGRICULTURE : massive pumping and dessalinization of the sea water to
promote irrigation and/or cultures under-greenhouse
- THERMOLYSES :
* of
water to 3000°C to get hydrogen (H2),
* of
the biomass to 1300°C to get gases leading to liquid hydrocarbons
of 2nd generation
The
PHRSD is the only machine giving the means of a prosper agriculture
even in too sunny zones (ideally placed
near of an ocean) ANDin the same time
the clean thermal energy to get gases of synthesis directly combustible
(H2, CO) or recombined in liquid heavier fuels (Diesel, Ethanol...)
which are easier to manage.

BIGOT's conference, High Commissioner to the atomic energy
This project is the
key of a perfectly clean and abundant energizing mix, with smoothing of the productions
and reliability of the electrical network by the interconnection of all
energizing potentials "biomass", wind, hydraulic and
especially solar within a vast geographical space going
from the
Scandinavia to the Subsaharian
Africa
while passing by the Middle East.
It is also a great
opportunity to lead a harmonious co-development with many economically unsteady countries.
