Chlorophyll solar panel Printer Friendly Version
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 Printer Friendly Version
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.

Electronic cable labeller Printer Friendly Version
I've been looking everywhere for a very simple, cheap but ingenious device that prints labels for electrical/electronic cords and cables.
How many of us who have multiple electric/electronic/computing devices have coils of cables with various ends that we don't know how to organize while they aren't being used? One particular beef is the power-supply bricks that always seem to get separated from their device. They are rarely labelled and you end up having two or three hanging around but have no idea what device they were used to power -- and plugging in the wrong adapter could fry a device if it's the wrong one.
I was thinking of something resembling a stapler, except it would be "filled" with white flexible plastic tape that somehow one could enter a name onto -- say, "USB to iPad Mini" and then clamp it around the cord somehow and it would produce a tag with the words "USB to iPad Mini" on both sides. It would have to be durable but not too wide -- in other words, about half the width of Scotch tape. It would be white or colored, depending on the "cartridge" or whatever you use to attach the tape, and there would have to be some way of inputting the text. The tags themselves could be as long or as short as you wanted, depending on the descriptions; thus, you could have a tag that said "Firewire to Thunderbolt for Canon Elura 100" or in the case of a power brick, "Power supply for label printer."
At the moment what I'm doing is using a Dymo label printer to print out the text and then, because the tape is inexplicable clear, attaching it to label paper, then cutting that out to make a tag, then attaching it to the cord -- very tedious and laborious work if you have 100 cords to do.
I have never seen anything like this anywhere. The only reward I would want is to have one for my personal use! I myself have no electronics knowledge or inventor skills whatsoever. Perhaps you could suggest a DIY hack that would at least reduce the work to a quick under-a-minute process? And something SIMPLE -- I don't need to be able to select among 20 fonts or tape widths.
Reward: Have one of these made for me for free!
