secondary post, mods, please delete the one in the forum less fitting for this topic.<br /><br />i thought this was an interesting video. im curious about this solar cell. is it feasable?<br />http://www.youtube.com/watch?v=kROgE4Jdm-k&NR=1<br /><br />(Locked; duplicate thread.

Cost feasibility depends upon myriad non-scientific consideration such as acceptable return on investment, cost of money. Technically speaking, it will work BUT: <br /><br />They are going to put about 3kW of light into a balloon. Probably 2500W will convert to heat and be trapped inside. There must be some sort of active heat exchange between the solar cell and the outside or the cell will fry.<br /><br />Lifetime of the plastic will be short (maybe a year) before it will degrade.<br /><br />You need a sun tracking device.<br /><br />I think there might be some advantage here for some specialized needs. I would like to see some testing data before I agreed with them that this is the panacea we need before 2050. <div class="Discussion_UserSignature"> <p> </p><p> </p> </div>
