Basically it allows you to store a bit in small writtable cells. When needed, you can read it by applying a pulse to the left side. If the BRAY goes through, it's a 0. If not, then a 1. Then it will be beamed up to what ever reading device there is. The idea is a really small mercury switch modified with a light sensor. The difference between this and other systems is, it allows you to write and read. To write, you simple apply 3 pulses( maybe four incase it doesn't rise) and it heats/cools the substance inside in order to block or open the pathway for BRAY.
Hopefuly some can use this to their advantage, if you do I want credit to be added.
