Energy Conservation - Parking Lots Printer Friendly Version
Have you ever seen the city lights at night ... noise pollution right? Well what about all the costs associated with those lights? Think of all those huge parking lots that have giant lights glowing all night long ... why? Now the facility owners and management will tell you it's about security, which is vaguely reasonable. However, they only need to be on when someone is there.
IDEA: Add motion sensors to all those light poles so that when someone moves in the area at night, the lights come on, but otherwise it is peacefully dark and quiet. Given the spacing of these poles typically should create a "grid" that would light an area with any activity - security maintained. Plus the cost savings from electrical conservation.
Reward: Credit for expressing the idea.

4-Day Work Week Printer Friendly Version
Virtually all of the discussions on how to reduce gas consumption and traffic congestion involves increasing the supply: Pump more oil, refine more gasoline, build more roads, more busses, new transit systems.
Yes, we need to do those things and more; but, we can make faster, highly effective gains with very little cost through a relatively painless adjustment in our livestyles. Let's institutionalize the 4-day work week.
Here's what it can do:
*Reduce commuting traffic by as much as 20%

*Reduce gasoline consumption and smog from automobiles by a similar amount.

*Give many families the opportunity to spend more time together, including many 3-day weekends.

*Car engines and tires will last much longer.
Here's what it cost:
*Local, regional, state, and federal bureaucracies will have to spend time and energy devising schedules.

*Some agencies and businesses will probably have to remain on the 5-day work week. Schools are one example.

*Longer work days might pose too much difficulty for some families.
Several states are already devising plans for the 4-day work week. Looking at the concept on a national scale might be very beneficial for our country.
