Save water Printer Friendly Version
The reservoir in your toilet is much too large for the quantity of water needed to flush out the contents after use. Suppose if everybody put a red brick in the bottom of their reservoir how much water that would save!

Cleaning air pollution with a hepa filter Printer Friendly Version
I had this idea for a few years and just want to put it out there. There are hepa air filters in homes that are ionic and clean pollutants in the air. So why can't we build one big ionic hepa filter for the air pollution we already have. We can also reuse the oils that are captured as another way conserving. Also if this is too much money maybe we can create smaller versions and put it in the exhaust of our cars. If it works in our home why not in the open air.
Reward: I just would like to be acknowledged in the project as to where the idea came from and be the first person to get this product if it goes in cars.

Off-peak energy storage Printer Friendly Version
Take advantage of excess electrical production capacity during night-time hours by equipping homes and businesses with large battery systems. This approach has been suggested for electrical cars where the disadvantage is the size of the battery system, but this would be much less of an issue for homes and businesses. Power companies would need to provide a cost incentive to encourage the use of these and the energy storage mode would be best controlled remotely by centralized operation at the power company to optimize efficiency. Current battery technology could be implemented easily. Having these energy storage devices would likely encourage individual consumers to add solar-voltaic or wind energy collection technology to work with the storage system.
