They say the mark of a great company is knowing when to cut your losses and run. Well, it seems as though Tesla is on the verge of ditching its battery swap service which was launched with the Tesla Model S electric vehicle. The idea was that battery swap stations would be built across America allowing Tesla Model S users to book an appointment which will allow them to swap their discharged batteries for fully charged replacements.

The idea seemed good and all Tesla Model S owners were contacted but only a few took up the company’s offer to visit the one and only battery swap station open to the public at the moment.

Una nueva investigación ha sugerido una revisión a la forma en que los dispositivos móviles se fabrican y se contratan, con el fin de detener los efectos nocivos sobre el medio ambiente causados ​​por los actuales modelos de negocio.

Investigadores de la Universidad de Surrey, Inglaterra, analizaron la vida útil de los dispositivos móviles, desde su producción y uso hasta su disposición, para ver qué impacto tiene cada etapa de... 

Canada has already had its share of wildfires this season, and the smoke from these wildfires is slowly drifting south over the United States' Midwest.  The drifting smoke can be seen in this Terra satellite image over Lake Michigan, as well as parts of Minnesota, Wisconsin, Indiana and Ohio. 

The smoke released by any type of fire (forest, brush, crop, structure, tires, waste or wood burning) is a mixture of particles and chemicals produced by incomplete burning of carbon-containing materials. All smoke contains carbon monoxide, carbon dioxide and particulate matter (PM or soot). Smoke can contain many different chemicals, including aldehydes, acid gases, sulfur dioxide, nitrogen oxides, polycyclic aromatic hydrocarbons (PAHs), benzene, toluene, styrene, metals and dioxins.

A study on ash blasted from volcanoes is a first step towards accurately assessing where it is safe to fly during eruptions, according to the authors. The researchers found that the ash grains ejected into the atmosphere have diverse shapes and properties. They also learned that big grains can travel further than was previously estimated. All this could improve existing models of ash concentrations, which governments and airlines use to make flight decisions during eruptions, they say. Ash can cause aircraft engines to fail.

Most Americans are aware that food waste is a problem, are concerned about it, and say they work to reduce their own waste, but nearly three-quarters believe that they waste less food than the national average, new research suggests. The findings, from the Johns Hopkins Center for a Livable Future (CLF) at the Johns Hopkins Bloomberg School of Public Health, are significant given that 31 to 40 percent of the American food supply goes to waste, primarily in homes, stores and restaurants. The top foods wasted, by weight, are fruits and vegetables, due in part to their perishability and bulk. Food waste costs Americans $161.6 billion annually.
