Why Your Next Phone Could Be Powered By Seawater
Lithium is more than just a pretty solid Nirvana track – it’s also the reason that the portable computer in your pocket can keep on tweeting, e-mailing and otherwise vibrating for hours on end.
But soon there may not be enough available to go around.
As the demand for long-lasting batteries in cell-phones, laptops, and electric cars increases, so too does demand for Lithium, their key ingredient.
The U.S. Geological Survey estimated recently that conventional lithium reserves provide enough for production of 37,000 tons of the element per year for 365 years. That sounds like a lot, but with over a million electric cars expected in 2020, the development of battery clusters that power smart homes (like Tesla’s Powerwall), and increasing availability of lithium-powered consumer electronics, demand is sure to rise exponentially every year.
To battle the problem of Lithium shortage, researchers are looking to some unconventional sources. In Japan, for instance, scientists at the Atomic Energy Agency are working on a method to extract lithium from seawater through dialysis. According to a report from MIT Technology Review, “The system is based on a dialysis cell with a membrane consisting of a superconductor material,” a sentence which presumably means something to someone, somewhere.
Though the method is a long way away from being used commercially, one of the lead scientists on the project, Tsuyoshi Hoshino wrote that this particular method of extracting Lithium “shows good energy efficiency and is easily scalable.” Hoshino adds that his method could be commercialized in five years.
If Hoshino’s method makes it to commercialization, it could be a huge boom for the lithium battery industry, especially to powerhouse Tesla. Mineral assays of Nevada’s salt lakes have shown promising concentrations of lithium, which also happens to be where the battery pioneer plans to build its massive battery production plant, known as the “Gigafactory.”
For now, though, we’re stuck with a reliance on more conventional lithium sources.
Budget ‘Chaos’ Threatens Army Reset: Retired General
One thing is standing in the way of a major ongoing effort to reset the U.S. Army, writes Carter Ham, a retired four-star general who’s now president and CEO of the Association of the U.S. Army, at Defense One. “The problem is the Washington, D.C., budget quagmire.”
The issue is more than just a matter of funding levels. “What hurts more is the erratic, unreliable and downright harmful federal budget process,” which has forced the Army to plan based on stopgap “continuing resolutions” instead of approved budgets for nine straight fiscal years. “A slowdown in combat-related training, production delays in new weapons, and a postponement of increases in Army troop levels are among the immediate impacts of operating under this ill-named continuing resolution. It’s not continuous and it certainly doesn’t display resolve.”
Pentagon Pushes for Faster F-35 Cost Cuts
The Pentagon has taken over cost-cutting efforts for the F-35 program, which has been plagued by years of cost overruns, production delays and technical problems. The Defense Department rejected a cost-saving plan proposed by contractors including principal manufacturer Lockheed Martin as being too slow to produce substantial savings. Instead, it gave Lockheed a $60 million contract “to pursue further efficiency measures, with more oversight of how the money was spent,” The Wall Street Journal’s Doug Cameron reports. F-35 program leaders “say they want more of the cost-saving effort directed at smaller suppliers that haven’t been pressured enough.” The Pentagon plans to cut the price of the F-35A model used by the Air Force from a recent $94.6 million each to around $80 million by 2020. Overall, the price of developing the F-35 has climbed above $400 billion, with the total program cost now projected at $1.53 trillion. (Wall Street Journal, CNBC)
