Pennies for your thoughts

Here's an idea: Take pennies out of circulation to save the U.S. government some money - it costs more than one cent to print a penny, why print them? It doesn't make "cents". Haha...! No, I'm not done yet.Round prices to the nearest 5, 10, or 25 cents. Any rise in prices will be directed towards moving the world in a "better" direction, faster: Research into zero-emission transportation and energy; putting some power behind the renewable resources movement; etc. These are things that need to have money behind them. Borrowing from China isn't a viable option forever.These two things in conjunction will help make big strides for the U.S., and for humanity in general. Besides, the price of things are going up anyway, wouldn't it be better if it was going towards a good cause?
