Bacteria/Yeast Mixture Energy Source Printer Friendly Version
You could, potentially, run anything from a car to an air plane with this. Any toy could use it and it would be environmentally safe and safe to eat. You could use it anywhere, at any time much like making beer but, with an immediate reaction. You can use baking soad and vinigar but, you don't get hours of energy from that. A very easy, inexpensive, all purpose energy source for any, possible, imaginable use, within reason.

Home recycler Printer Friendly Version
Develop a home recycler which will take all of your recyclable material and crush, grind, reduce, compact and store the material until you are ready to dispose of. I suggest the following criteria:
- Items to dispose of - wood, plastic, glass, metals
- Must be a system inexpensive enough for the average home
- Must be easy to operate and by one person
- End product must be ready to dispose of, preferably able to sell the product to local recycling establishment.
Reward: I'd like ot participate with anyone that would like to develop this concept further
