Unconventional Fracking: Changing The Future Of Drilling - Praxair, Inc. (NYSE:PX) | Seeking Alpha
Thomas Pangia has written an excellent article about Praxair and the possible future of CO2 in oil well fracking. Some of the comments about Praxair were also very interesting such as the company using hydrogen for industrial benefits. I actually owned PX in the distant past, but I got sidetracked by other stock picks in recent years. However, Praxair is on my watch list now for buying in the near future. The stock has increased in price more than three times in the past 10 years, and PX survived the last bear market by a wide margin over the S&P 500.
