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.
Chart of the Day: SALT in the GOP’s Wounds
The stark and growing divide between urban/suburban and rural districts was one big story in this year’s election results, with Democrats gaining seats in the House as a result of their success in suburban areas. The GOP tax law may have helped drive that trend, Yahoo Finance’s Brian Cheung notes.
The new tax law capped the amount of state and local tax deductions Americans can claim in their federal filings at $10,000. Congressional seats for nine of the top 25 districts where residents claim those SALT deductions were held by Republicans heading into Election Day. Six of the nine flipped to the Democrats in last week’s midterms.
Chart of the Day: Big Pharma's Big Profits
Ten companies, including nine pharmaceutical giants, accounted for half of the health care industry's $50 billion in worldwide profits in the third quarter of 2018, according to an analysis by Axios’s Bob Herman. Drug companies generated 23 percent of the industry’s $636 billion in revenue — and 63 percent of the total profits. “Americans spend a lot more money on hospital and physician care than prescription drugs, but pharmaceutical companies pocket a lot more than other parts of the industry,” Herman writes.
Chart of the Day: Infrastructure Spending Over 60 Years
Federal, state and local governments spent about $441 billion on infrastructure in 2017, with the money going toward highways, mass transit and rail, aviation, water transportation, water resources and water utilities. Measured as a percentage of GDP, total spending is a bit lower than it was 50 years ago. For more details, see this new report from the Congressional Budget Office.
Number of the Day: $3.3 Billion
The GOP tax cuts have provided a significant earnings boost for the big U.S. banks so far this year. Changes in the tax code “saved the nation’s six biggest banks $3.3 billion in the third quarter alone,” according to a Bloomberg report Thursday. The data is drawn from earnings reports from Bank of America, Citigroup, Goldman Sachs, JPMorgan Chase, Morgan Stanley and Wells Fargo.
Clarifying the Drop in Obamacare Premiums
We told you Thursday about the Trump administration’s announcement that average premiums for benchmark Obamacare plans will fall 1.5 percent next year, but analyst Charles Gaba says the story is a bit more complicated. According to Gaba’s calculations, average premiums for all individual health plans will rise next year by 3.1 percent.
The difference between the two figures is produced by two very different datasets. The Trump administration included only the second-lowest-cost Silver plans in 39 states in its analysis, while Gaba examined all individual plans sold in all 50 states.
