can use solar to boil water to 100degree celcius?how much power need to boil water?

Answer 1

Of course you can use solar energy to boil water to 100 C. Actually solar energy can be converted to electrical energy which can then be used to boil water to any temperature. Regarding the power, it will depend on the quantity of water not on the temperature.

Answer 2

You can, but it depends on a couple of different things. First you need to focus your solar energy. Probably with mirrors and at least one lense.

As far as how much power. Depends on the water starting temp. You will need 1 BTU, per degree farenheight, per gallon of water. So, if you were doing an experiment, or a series of small experiments, I would use a small amount of water, say 2 ounces, and figure your power by dividing by 64 x's your hours.

Answer 3

it can be done. the reason it is not done is because then you have a 2 phase system, one that has to handle both water and steam. this would then be a pressurized system which makes the design of the solar collector much more expensive. this system also has to convert steam back to water again, via a radiator and air handler to move cooling air through it. If you are thinking of using it to power a steam engine, might i suggest a photovoltaic solar system as being more efficient.

Answer 4

Of course, you just need a focusing lens or mirror.
