for some reason last night when I tried it did not let me email K^2, but now today it will. I must have been tired when I wrote my posted my note. What I did was to just repost what I wrote into that thread so that others can benefit from any response.
I am interested in the math involved to calculate the ideal natural teardrop shape for a hot air balloon. I want to learn the details of what is involved to calculate this accurately.
I read your reply which was a really nice start, but it unfortunately does not get into the details of how...

Is it possible to filter out infrared light using a prism, and if so, how? What is the math involved to do this?
I want to come up with some effective, durable ways to filter out IR light for solar panels, to keep their temperature lower to make them more efficient.
Solyndra is very interesting, but I can't tell if how well they are truly bouncing light around in their glass tube to harvest all of the available light; they are very expensive--I'm hoping to provide a more reasonably priced solution.
I would rather use cheaper refraction material to focus...
Given what you have said the first thing that comes to mind is to stack the solar cells at an angle, providing enough gap in between each cell to insert an impedence transformer to refract the light onto them at an optimal angle, or better yet, by stacking them vertically in sandwiched pairs...
I want to maximize solar cell efficiency regardless of the sun's angle and so I've been looking at placing Compound Parabolic Concentrator (CPC) over the top of a high efficiency round solar cell. If I come up with a good design then I would like to try and manufacture some of them to see if I...
I agree with you; I think the activist idea is pretty funny, it made me laugh, and has some truth to it--also the fact that people choose so many different paths for their life's journey.
Regarding the trip over there, it would either be done with bone density drugs and/or a rocket design...
Yeah, I know what you mean... you're right and I'd speculated on that too from time to time; each time I think about it the two thoughts that run through my mind are:
people tend to always want to be strong not weak, and if a simple pill (assuming that it's not grossly expensive or has side...
I agree with so much of what you are saying here; although I tend to be more of a person of "balance" and feel that anything can be taken to excess that is eventually bad, it seems there is a lot of gray between where that "excess" line falls--we are all unique and should be applauded for...
I know we've all watched sci-fi and laughed about how fake it was; I would never want to do such a thing, so while the focus is not on the gravity, I do need to have some explanation about how we're dealing with the gravity--this is typically done in side passing conversations where it's not so...
I appreciate any feedback, even kindly worded critique as you've done. Thanks for that. From what my research has shown, the sickness that you speak of greatly reduceds as the diameter increases; I've read many studies that show life from the "Coriolis effect" is fine with diameters of 1km or...
I am researching for a sci-fi screenplay that I am writing for fun. To keep bone density from losing the estimated 1.5% per month on Mars I want to simulate Earth gravity by having the colonists live aboard condominiums that are fitted with a rail car suspension and travel in a perfect circle in...
