Diesel Powered iPhones?

If your iPhone were powered by diesel fuel, it could last for 10 days of regular use with a standby time of 152 days! The Wall Street Journal takes a look at the energy densities of several power sources and learns that diesel fuel, while maybe not practical to power an iPhone, has more energy per gallon than other alternatives.

Why is diesel technology so fuel efficient? A combination of the energy-rich properties of the fuel, and the efficiency and completeness of the combustion of fuel to create useful mechanical energy. Diesel is a petroleum-based fuel with the highest energy density among transportation fuels - that's more energy per gallon than other alternatives. The U.S. Energy Information Administration states that few transportation fuels surpass the energy density of diesel. Because of its unmatched power density, energy efficiency and widespread availability, diesel is not only the primary commercial transportation fuel used for goods and people movement by road, rail or water, it also powers the majority of industrial construction, agricultural and mining equipment on a global basis. International experts predict that diesel is on course to remain the number one global transportation fuel. The International Energy Agency recently stated that diesel is expected to overtake gasoline as the top transportation fuel used in passenger vehicles and in the freight transportation sector. One of the largest global oil producers, ExxonMobil, recently confirmed diesel’s expected dominance saying that diesel will surpass gasoline as the number one global transportation fuel by 2020 while also stating the much of the anticipated growth in diesel will come from emerging economies.

New cleaner diesel technology and fuel will play an increasing role in U.S. and international efforts to improve air quality standards. Demand for clean diesel fuel will only increase around the world as other countries’ economies grow and they search for clean, cost-effective fuel solutions, driving demand for powerful modern diesel engines that will also improve air quality and reduce carbon emissions.

Newfound petroleum reserves across the country have resulted in America’s energy abundance. Because of these oil and gas reserves, the U.S. Energy Information Agency states that as of 2011 the U.S. is a net exporter of petroleum products and ultra-low sulfur diesel fuel (ULSD) is the number one petroleum export. While the U.S. is a net exporter of ULSD, recent studies including the Fuels Institute recent analysis has determined that there’s more than ample supply to meet domestic demand. The U.S. and international refining industries are making adjustments and investments based on shifts in global demand for refined products that include increased demand for diesel fuel. The investments have assured adequate production capacity to meet future global diesel needs.
