The “surfactant” chemicals found in samples of fracking fluid collected in five states were no more toxic than substances commonly found in homes, according to a first-of-its-kind analysis by researchers at the University of Colorado Boulder.

Fracking fluid is largely comprised of water and sand, but oil and gas companies also add a variety of other chemicals, including anti-bacterial agents, corrosion inhibitors and surfactants. Surfactants reduce the surface tension between water and oil, allowing for more oil to be extracted from porous rock underground.

In many ways electric car technology jumped to far too quickly leaving behind electric vehicle charging systems which for many years have been totally inadequate. There has been major concern amongst motorists around the world that even the most technologically advanced electric vehicle would be unreliable if you are not able to charge it when and where you wanted. This has held the electric car industry for some time although thankfully governments around the world are now focusing upon electric car charging networks.

This then begs the question – could electric car chargers be the next growth industry?

If the majority of light-duty vehicles in the United States ran on higher-octane gasoline, the automotive industry as a whole would reduce its carbon dioxide emissions by 35 million tons per year, saving up to $6 billion in fuel costs, according to a new analysis by MIT researchers.

In a study published in the journal Environmental Science & Technology, the team considered a scenario in which fuel is manufactured under a redefined octane rating — the measure of a gasoline’s ability to resist engine knocking during combustion.
