Clear Wax Crayon for Protecting Ink From Accidental Erasure Printer Friendly Version
When you label things with indelible ink, it can still be washed off by alcohol. This can be inconvenient if you have to work with alcohol and other solvents. For example, you may be working in a lab and labelling your tubes with a Sharpie and some alcohol spills from the tube and wipes off the labels on your tubes. This is very bad, because now you don't know which sample is which.
My idea is to make a clear wax crayon that you use to trace over your ink with. The layer of wax should protect your ink from washing off in alcohol and still leave the ink visible for reading.

small package could offset the climate costs for homes, business, industry, even far parts of the world without power.
Several designs, including:
-roof mounted system with HVAC installed thermal unit. affordable, and very energy efficient. buy it, hook it up, and enjoy the savings.
-portable units for camping, military, personal, even emergency response. set it up and use it, that easy.
-medical units reqire extra purification. throw in a HEPA filtration system and extra power for lighting and controls and you have a mobile medical support system. portable and permanent units still offer the full benefits of any system, free power.
Typical estimates gather that "structure" emissions make up 29% of our nations pollution. adding any kind of offset plus better benefits than traditional methods will reduce, recycle, and reuse our energy more wisely.

Illuminated PC cables Printer Friendly Version
Computer cables that light up when you touch them or press a button on them to aid in you tracing where the cable is plugged in. Also, the cables could change brightness or flash based on what type of data is passing through them, or direction of data. Data centers where there are tens of thousands of cables could really benefit greatly.
Reward: I wouldnt mind having a few of the products. I would like a reference in the documentation for attributing me as helping with the concept.
