Road Resurfacing Machine (Recycle) Printer Friendly Version
To decrease costs of resurfacing a road and reduce amount of asphalt used. The idea would be to design a paving machine which uses microwaves to heat up old asphalt on the road and enabling it to be picked up easily. The machine would then remix the asphalt to the proper ratio by adding extra asphalt tar and then resurface the road all in a single operation with the same machine. This machine would eliminate the system used presently whereby pavement is stripped, new pavement is brought in days later and the road is resurfaced weeks later.
Reward: New roads resurfaced cheaply with less noise and disruptions.

Sonic Cleaner for Concrete Garden Slabs Printer Friendly Version
I use a pressure water jet to clean concrete garden slabs. For reference, I used 80 gallons of water and the project took six hours. I cannot imagine how much electricity was used. I believe that technology exists to manufacture a sonic cleaner similar to a portable metal detector. If this could be achieved, then world wide savings in water, electricity, and labor hours could be very significant.
Reward: Confirmation that this my original thought.
