Ever since I saw the Belkin Lapdesk I thought that it needed improvement. It needed either passive or active cooling of some form, and I was hopping to not add another thing that needed to be plugged into a wall outlet. This mod adds two active fans that are plugged in to a 12v wall wart, and while I definitely it improves the overall usefulness of the stand it doesn't meet my other goal of not wanting another device sucking power.
I saw an article a few days ago about Icyballs that may be closer to what I am hopping to use. It would require electricity as I am fairly sure I need to have a microcontroller to engage the heat element to reverse the natural evaporation process. I have no experience with this type of work though so I think I am going to need to find a chemistry nerd and probably a welding nerd to pull the whole process.
