L'HVDC, combien cela coûte-t-il ?
Already today it is quite possible to transmit power in the order of 6000 MW per line over a distance from Sahara to central and even northern Europe. To transmit 700 TWh would need a transmission capacity of around 150 GW. This means that around 25 lines would be needed at a total cost (European conditions) of around 60 billion EUR or approx 0,5 Eurocent/KWh..." - Gunnar Asplund , ABB Power systems, Grid Systems, HVDC, 771 80 Ludvika, Swede

Le désert du Thar (Inde) : un potentiel solaire colossal !
Voici une réflexion d'une grande richesse de Nitin Phansalkar, Inde :
" (...) In order to maximize the power output, the plant must be located at a place that receives a "plenty" of sun throughout the year. One such place in India is Thar Desert in west Rajasthan. Following characteristics of Thar Desert make it an ideal location for a solar thermal power plant (STPP) :
1. Area: 2.34 million km2
2. Solar Intensity: approx 6 kWh/m2/day
3. Sun Availability: 345-355 days in a year
4. Rains occur only for 10-20 days in a year
There are a few "Strategic Advantages" that Thar Desert presents, which would make it a NexGen Powerhouse of India. These are as follows :
(1) Strategic Location:
- South Boundary of Thar Desert : Arabian Sea is just 80-90 kms away and hence a STPP located at the south boundary can double-up as a water desalination plant also providing clean water to local people. Gujarat industrial cluster is also very near from the south boundary and hence the power generated can act as a peak power to these industrial units at a reasonable rate.
- North-East Boundary of Thar Desert : Power hungry states of Punjab, Haryana and Delhi can get peak power especially during hot summers with a STPP located nearby.
(2) As it is a desert, it is scantly populated and most of the land is government owned and hence land acquisition, relocation of local people and associated issues will be minimal.
(3) The local people live a tough life as the land is arid and there is no industry. These local people can get a means of livelihood in constructing and maintaining the STPP. STPP will usher-in an era of all round development in this area.
Initially, the STPPs would provide only "Peak-hour Power" i.e. only during daytime when solar energy is available. Later on, when the cost is reduced, the solar energy storage (in the form of say molten salts) can be built to provide power after sunset. (...) "

Global Energy Network Institute : un grand pas vers le futur
Linking Renewable Energy Resources Around the World
Relier les ressources énergétiques renouvelables du monde entier
"There is no energy shortage, there is no energy crisis,
there is a crisis of ignorance."
Il n'y a pas de manque d'énergie, il n'y a pas de crise énergétique,
il y a une crise de l'ignorance.
http://www.geni.org
World Web Of Electricity Charged Up - " It is a common misconception that long-distance energy transfers are impractical, Powers said, explaining that in the 1930's there was a transmission limit of 350 miles. "That limit grew to 1,500 miles in the 1960's and is now well over 4,000 miles using Ultra-High Voltage and High-Voltage Direct Current (HVDC) technology
(...) Imagine an energy version of 'Napster'. "We're talking about peer-to-peer energy trading where a solar homeowner in San Jose can capture kilowatts from the sun - and sell them to a homeowner in Shanghai - instantaneously.
That's the future. (...)"
http://www.carbonfree.co.uk/cf/news/wk10-07-0001.htm
Avec les câbles HVDC (High Voltage Direct Current), les pertes lors des transfert d'électricité sont inférieures à 3% pour 1000km. 4000 miles c'est...6437 kilomètres (20% de perte sur cette distance). Ou encore Paris-New-Delhi (Inde) ! Une centrale solaire au Pakistan ou en Inde peut alimenter en électricité Paris pendant la nuit...

New York - Bill Clinton et Charlie Crist promettent un véritable boom du solaire concentré aux USA
Clinton, Crist Announce FPL Solar Power Plant - NEW YORK -- Pushing politics aside, Republican Gov. Charlie Crist and former Democratic President Bill Clinton took the stage together to announce that Florida Power & Light will build a solar power plant in Florida as part of a $2.4 billion clean energy program. "This is a huge deal for America and I think potentially a huge deal for people all around the world who want to do this," said Clinton, who introduced Crist and company Chief Executive Lew Hay at the beginning of the Clinton Global Initiative conference.

Clinton promises solar sunrise - Good old Bill Clinton has done it again. Perhaps inspired by David Mills' speculation on the capacity of solar thermal power plants to deliver emissions-free electricity in this country, his confab going on in NYC presently has united said visionary's solar thermal company Ausra with utility giants Florida Power and Light (FPL) and Pacific Gas and Electric (PG&E). According to a press release, FPL has committed to building 500 megawatts of solar thermal power while PG&E promised to purchase 1,000 megawatts of electricity generated at such solar thermal power plants.

Une centrale solaire à concentration dans les Alpes suisses !
La future centrale solaire des Diablerets séduit - (...) La technologie qui sera utilisée dans les Alpes vaudoises (voir LT du 3 avril dernier) repose sur des capteurs solaires extraplats à concentration qui, à partir du rayonnement du soleil, produisent instantanément de la vapeur à des hautes températures (200 à 300 degrés). «Une attention toute particulière sera portée sur l'intégration de ces 10000 m2 de 
panneaux solaires dans le paysage, en bordure du domaine skiable», assure Yassine Allani. La puissance de la centrale d'Isenau atteindra 1,5 mégawatt, soit l'équivalent de la consommation de quelque 500 ménages. La centrale alimentera également en courant vert le train Aigle-Sépey-Diablerets. (...)

All we need is SUN
Can Sunshine Provide All U.S. Electricity?
By David Biello, 19 septembre 2007, Scientific American.com
Large amounts of solar-thermal electric supply may become a reality if steam storage technology works—and new transmission infrastructure is built (...) But physicist David Mills, chief scientific officer and founder of Palo Alto, Calif.–based solar-thermal company Ausra, has bigger ideas: concentrating the sun's power to provide all of the electricity needs of the U.S., including a switch to electric cars feeding off the grid. "Within 18 months, with storage, we will not only reduce [the] cost of [solar-thermal] electricity but also satisfy the requirements for a modern society," Mills claims. "Supplying [electricity] 24 hours a day and effectively replacing the function of coal or gas."
Spare Power Sufficient to Fuel Switch from Gas to Electric Cars
