I've decided to start compiling a list of all of the applications for heliostats. I have been researching them for the last year now and, naturally, have stumbled across ideas that are quite inspiring. Writing this list and presenting my own ideas for each section in one sitting, however, would be torture, so I won't try. Instead, the work will be spread across several days or maybe even weeks. Nothing is in any particular order. I just put it up as I think of it.
Of course, if anyone would like to add their own thoughts on the subject, please feel free to do so. Don't let me leave anything out. If you can think of a use for heliostats that no one else has, put it up. Thanks!
To start things off, we're going to take a look at heliostats reflecting sunlight through prisms. The result of this combination is, well, just downright pretty.
Here is a link to some pictures. http://erskinesolarart.net/
There is a lot there if you just click around.
I can also think of some practical possibilities too. For example, one problem with solar cells is that their efficiency goes down as their temperature goes up. This means that it isn't feasible to increase their power output just by shining more light on them with mirrors. However, I know that solar cells are sensitive to certain frequencies (AKA colors) of light more than others. With a prism, you could shine only the light that is useful for generating electricity on the solar cell while the other parts of the spectrum are sent elsewhere so they won't overheat it.
Something similar could be done with plants as well. One problem with greenhouses is that they can overheat easily, even in the winter. I know that plants like certain frequencies more than others, so perhaps a setup similar to the solar cell idea would work with them as well.
Thanks for reading!
More will come.
