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.
Stat of the Day: 0.2%
The New York Times’ Jim Tankersley tweets: “In order to raise enough revenue to start paying down the debt, Trump would need tariffs to be ~4% of GDP. They're currently 0.2%.”
Read Tankersley’s full breakdown of why tariffs won’t come close to eliminating the deficit or paying down the national debt here.
Number of the Day: 44%
The “short-term” health plans the Trump administration is promoting as low-cost alternatives to Obamacare aren’t bound by the Affordable Care Act’s requirement to spend a substantial majority of their premium revenues on medical care. UnitedHealth is the largest seller of short-term plans, according to Axios, which provided this interesting detail on just how profitable this type of insurance can be: “United’s short-term plans paid out 44% of their premium revenues last year for medical care. ACA plans have to pay out at least 80%.”
Number of the Day: 4,229
The Washington Post’s Fact Checkers on Wednesday updated their database of false and misleading claims made by President Trump: “As of day 558, he’s made 4,229 Trumpian claims — an increase of 978 in just two months.”
The tally, which works out to an average of almost 7.6 false or misleading claims a day, includes 432 problematics statements on trade and 336 claims on taxes. “Eighty-eight times, he has made the false assertion that he passed the biggest tax cut in U.S. history,” the Post says.
Number of the Day: $3 Billion
A new analysis by the Department of Health and Human Services finds that Medicare’s prescription drug program could have saved almost $3 billion in 2016 if pharmacies dispensed generic drugs instead of their brand-name counterparts, Axios reports. “But the savings total is inflated a bit, which HHS admits, because it doesn’t include rebates that brand-name drug makers give to [pharmacy benefit managers] and health plans — and PBMs are known to play games with generic drugs to juice their profits.”
Chart of the Day: Public Spending on Job Programs
President Trump announced on Thursday the creation of a National Council for the American Worker, charged with developing “a national strategy for training and retraining workers for high-demand industries,” his daughter Ivanka wrote in The Wall Street Journal. A report from the president’s National Council on Economic Advisers earlier this week made it clear that the U.S. currently spends less public money on job programs than many other developed countries.
