New study finds gasoline stations vent up to 10x more benzene fumes than previously thought

Green Car Congress

OCTOBER 6, 2018

A study led by environmental health scientists at Columbia University Mailman School of Public Health examined the release of vapors from gasoline station vent pipes, and found benzene emissions were 10 times higher than estimates used in setback regulations that determine how close schools, playgrounds, and parks can be to the facilities.

The pair has received $850,000 in grants to support the fabrication and testing of a prototype of the K6 engine; Shedd says he expects to have a prototype running by late fall or early winter. The engine incorporates a modified Brayton cycle ( earlier post ) into a continuous combustion engine system. —Timothy Shedd. —Tim Shedd.

For instance, Alexandre Milovanoff at the University of Toronto and his colleagues’ research (which is described in depth in a recent Spectrum article ) demonstrates the U.S. This is due to the 30 to 40 percent increase in emissions EVs create in comparison to manufacturing an ICE vehicle, mainly from its battery production.

Perspective: US Needs to Transition to Hydrous Ethanol as the Primary Renewable Transportation Fuel

Green Car Congress

AUGUST 30, 2009

US Environmental Protection Agency Grants Testing Waiver. In February, 2009, the US EPA granted Renergie, Inc. Essentially, the lower energy content of hydrous ethanol is counteracted by increasing engine performance due to higher heat of vaporization of ethanol and water in comparison with gasoline and anhydrous blends.

SEPTEMBER 19, 2009

Densities for steel springs and Li-ion batteries provide a comparison. Carol Livermore, associate professor of mechanical engineering and her team used an ordered grouping of carbon nanotubes (CNT) as a spring to store elastic energy for later use—much as a steel spring stores energy in a mechanical watch.

These use three-dimensional laser scanning technology to create a real-time map of their environment, then compare that real-time map to a pre-drawn map stored in the system. By making thousands of comparisons per second, they’re able to determine the vehicle''s location within a few centimeters. Resources.

Also, besides giving you the ability to charge at night when most utility rates are lower, future vehicle-to-grid (V2G) technology may allow you to sell some of your stored energy back to the utilities. The method that should seem most natural is charging at home.
