LEDs stories

 
It's tough to sleep in space. You're stuck in a noisy machine all the time, the sun comes up every 90 minutes, and everything is lit with a garish sci-fi fluorescence. About half of all astronauts have to resort to drugging themselves at some point to fall asleep, and NASA wants to make things easier with the help of color-changing LED lights.
 
When we choose to go to the Moon (or do other things out in space), the one of the major limiting factors to how long we can stay will be consumables. Simply put, can we ship enough food and water from home to keep astronauts fat n' happy? For a little while, sure, but semi-permanent outposts on the Moon will need their own farms, and that means LEDs. And nukes.
 
I'm a huge fan of the life-like Lego creations that people dream up. We've giant skylines, portal guns, sci-fi scenes and a gazillion other models we all drool over. Some of them have lights to add greatness to the overall effect of the model, but there's always the same problem: how do you power those little lights?
