Our Sun is the lone star in our solar system. Sun is virtually a fusion bomb fusing hydrogen into helium to produce white light. It thus contains mostly helium. However other heavier molecules of oxygen and even Iron are supposed to exist there in the solar region. Click - 1
The tokamak is one of several types of magnetic confinement devices, and is one of the most-researched candidates for producing controlled thermonuclear fusion power. Magnetic fields are used for confinement since no solid material could withstand the extremely high temperature of the plasma. An alternative to the tokamak is the stellarator. Click – 2
India is developing the heaviest and the largest parts of the Tokamak, the machine behind the biggest scientific collaboration on the planet, to produce unlimited supplies of cheap, clean, safe and commercial energy from atomic fusion. Click – 3
The basic premise behind Concentrated Solar Power is generating intense heat and light which can be converted into electricity using mirror configurations. CSP systems focus sunlight on a relatively small area thereby, producing high temperatures and simultaneous thermodynamic activity. One of the advantages of a CSP system is its compatibility with traditional power generation plants. However, the fuel in this case is sunlight which is environment friendly as compared to traditionally used fossil fuels. Click - 4
Renewable energy is energy that comes from resources which are continually replenished such as sunlight, wind, rain, tides, waves and geothermal heat. About 16% of global final energy consumption comes from renewable resources, with 10% of all energy from traditional biomass, mainly used for heating, and 3.4% from hydroelectricity. New renewables (small hydro, modern biomass, wind, solar, geothermal, and biofuels) accounted for another 3% and are growing very rapidly.[2] The share of renewable in electricity generation is around 19%, with 16% of electricity coming from hydroelectricity and 3% from new renewable.[2] Click – 5

Photo voltaic Solar Panels
Photovoltaics (PV) is a method of generating electrical power by converting solar radiation into direct current electricity using semiconductors that exhibit the photovoltaic effect. Photovoltaic power generation employs solar panels composed of a number of solar cells containing a photovoltaic material. Materials presently used for photo voltaic include mono crystalline silicon, polycrystalline silicon, amorphous silicon, cadmium telluride, and copper indium gallium selenide/sulfide. Due to the increased demand for renewable energy sources, the manufacturing of solar cells and photovoltaic arrays has advanced considerably in recent years.

JUWI India is a Bangalore based company which has executed several Solar Power Panel projects in India. I believe that the ROI of these panels is something like 4 to 5 years. Probably other Praja could enlighten. Click - 2
Disadvantage / Advantages of Direct Current [DC]
Direct current has inherent dis advantage:-
Hence there is a need for a DC to AC converter before transmitting the energy from solar panels, I belive.
AC can even be changed to DC by an adaptor that you might use to power the battery on your laptop. DC can be "bumped" up or down, it is just a little more difficult.
Inverters change DC to AC. For example, for your car an inverter would change the 12 volt DC to 120 Volt AC to run a small device. While DC can be stored in batteries, you cannot store AC.
Uninterrupted Power supply or “UPS” in short is a smart application. It is a boon to our city of Bangalore.
In the absence of UPS one had to keep candles handy in every house hold in olden days!

semi conductor as storage
while you prefer to vote for indium gallium pv cells to generate solar electricity ,make it more profitable through developing the magnetic semiconductor system for storage
Dr.Baby
Doc can you help?
Doc can you please give me some refcerence material on "Magnetic Semi conductor system" for storage please? I tried searching but I was not able to get a suitable one.

I was going through the posts, though not in detail; from what I gather, discussions are about eco friendly sources of energy & power transmision;
I have a humble plan;
rechargeable batteries can be charged with sunlight; I got information that a battery of about 3 ft x 2 ft x 2 ft size can be produce about 230 KVA of power (about 1 KW); if it poosible to charge these batteries using solar cells (uesd at traffic signals) in a period of 4 hours and if such a charged battery can run for about 30 hours, in tandem with other batteries, for driving electric motors for power generation, then 1000 such batteries can produce 1 MW of power;
so if proper engineering study is made probably, we should be able to produce cheap and abundant electricity from solar energy; imagine if 1 MW of power can be produced from about 1000 rechargeable batteries, then we can have hundreds of such plants producing about 1000 MW of pwer; this will a huge bulk of the energy needs of a atate like Karnataka;
may be some serious study can be done in this area, that would be of yeoman service to society, if it is parctical and successful
Many thanks
