| New Automotive Reflector
The invention is composed of two parts:1. The first part is a modulated retro-reflector structure where current or charge is used to modulate say, a MEMS retro-reflector structure. These devices are known in the literature having being proposed solely for optical communications where they need to operate at very high frequencies. See, for example, http://en.wikipedia.org/wiki/Modulating_retro-reflector2. The second part is a device that drives the modulating feature of the modulating retro-reflector. Typically this will be a MEMS structure that requires current or power modulated by a semiconductor device built into the structure or in a separate board. The power source can be either:a. a low power long-life battery and a photodiode that is used to detect (1) nightime/dark conditions and (2) incoming incident light, such that the modulating feature is only used when necessary to conserve power, or, b. more advantageously a built in photovoltaic solar cell that uses some of the incident light to drive the MEMS switching structure to enable modulation. This device can also include a rechargeable battery to store power during daylight periods.This invention is made by a number of means:1. The Modulating MEMS structure is made in a typical MEMS fab
2. The control electronics are made in various semico fabs and them fabricated into printed circuit boards - as per typical electronic devices
3. The whole lighting device is then packaged in a plastic housing, typically in Chine where this is done manuallyThe invention is used very simply where it replaces current static light reflectors.

| Chlorophyll solar panel
To sum it up quickly, I will spare you the high school science class info. Basically my idea is to use synthtic chlorophyll, first synthesized by Robert Woodward in 1960 at Harvard University, to make a photo cell capable of producing useable amounts of energy. I'm not the smartest guy but I imagine there are two major problems.1- Since chlorophyll is being made by plants regularly, I assume it degrades over time. There would need to be a way to either stop degradation completely (sounds very difficult if not impossible) or replenish it at a consistent rate.
2- Change how chlorophyll makes energy. Not sure how this would work exactly, but somehow alter chlorophyll to produce a type of energy capable of being stored in batteries. I'm not sure if this idea is even possible, but if a "green" solar panel was made, it would be very easy to market. Thanks for reading this, any additional input would be appreciated.

| SecPressure
This idea came to me while watching a show on TV about shop lifters. I was observing that shoplifting would not be possible if people knew they would more than likely be caught.The Idea then hit me: If there was a pressure sensitive tiles/film invented that could weigh the people/items in the shop.Then when an item is lifted off a shelf the computer system tracks it until the checkout. Each item is scanned and removed from the security list at checkout. If a person fails to pay for an item in the possession the doors fail to open/alarm is sounded. With a system designed right I should be able to track all customers in the store. Know what item was taken without looking. Get timestamps for security camera videos.Maybe it is a bit too futuristic.
