Hey Guys


If anybody has information related to neuclear-cytoplasmic ratio (the actual values for the 3 stages of cervical cancer(i.e HSIL LSIL and normal) please help me out here .any help is appreciated!!

solar energy-my views and explanation

Posted: 18 Feb 2011 05:17 AM PST

hi friends,
i am here with the thread for solar energy
if we think about solar energy there comes 3 questions into existence
1.why we went to solar energy?
2.what is it?
3.how we get it and what are advantages and disadvantages
i have some answers here
for 1st one
it can be explained as the sources we are available are wind energy,water energy ie.., hydel energy,thermal energy or coal energy,nuclear energy etc.........,
in this water,thermal and nuclear energies will come to an end at some time
wind energy,solar are having some disadvantages and others are still in research level
here wind energy generate only some limited energy and this will occur good when we heavy winds
coming to solar
its a source which exits until earth meets its doom
so.we came to the solar energy
next question is what is it?
i believe answer is this
its an energy which lasts forever for humans so it is energy coming from sun
in this we convert sun's heat energy to electrical energy
next question will be how we got it?
for this question there is a simple answer as from sun
here we convert sun heat to electrical energy by using solar cells and we can also call it as photo voltaic cells
these cells operation is kind of difficult to explain
in my view they are the cells kind of detectors which uses of photo detectors and takes energy
well.... now coming to advantages and disadvantages
advantages: it is total energy which generates until earth exits and we can generate electricity forever
disadvantages: it is exists for only sun appears i.e.....,
we get the energy for only 14 hours (saying depending on present technology)
and research is going to improve this

i hope we will get 24 hours supply from this energy at some day

@CEans: please continue this thread on giving your informations and views on this energy
