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.
Tweet of the Day: The Black Hole of Big Pharma
Billionaire John D. Arnold, a former energy trader and hedge fund manager turned philanthropist with a focus on health care, says Big Pharma appears to have a powerful hold on members of Congress.
Arnold pointed out that PhRMA, the main pharmaceutical industry lobbying group, had revenues of $459 million in 2018, and that total lobbying on behalf of the sector probably came to about $1 billion last year. “I guess $1 bil each year is an intractable force in our political system,” he concluded.
Warren’s Taxes Could Add Up to More Than 100%
The Wall Street Journal’s Richard Rubin says Elizabeth Warren’s proposed taxes could claim more than 100% of income for some wealthy investors. Here’s an example Rubin discussed Friday:
“Consider a billionaire with a $1,000 investment who earns a 6% return, or $60, received as a capital gain, dividend or interest. If all of Ms. Warren’s taxes are implemented, he could owe 58.2% of that, or $35 in federal tax. Plus, his entire investment would incur a 6% wealth tax, i.e., at least $60. The result: taxes as high as $95 on income of $60 for a combined tax rate of 158%.”
In Rubin’s back-of-the-envelope analysis, an investor worth $2 billion would need to achieve a return of more than 10% in order to see any net gain after taxes. Rubin notes that actual tax bills would likely vary considerably depending on things like location, rates of return, and as-yet-undefined policy details. But tax rates exceeding 100% would not be unusual, especially for billionaires.
Biden Proposes $1.3 Trillion Infrastructure Plan
Joe Biden on Thursday put out a $1.3 trillion infrastructure proposal. The 10-year “Plan to Invest in Middle Class Competitiveness” calls for investments to revitalize the nation’s roads, highways and bridges, speed the adoption of electric vehicles, launch a “second great railroad revolution” and make U.S. airports the best in the world.
“The infrastructure plan Joe Biden released Thursday morning is heavy on high-speed rail, transit, biking and other items that Barack Obama championed during his presidency — along with a complete lack of specifics on how he plans to pay for it all,” Politico’s Tanya Snyder wrote. Biden’s campaign site says that every cent of the $1.3 trillion would be paid for by reversing the 2017 corporate tax cuts, closing tax loopholes, cracking down on tax evasion and ending fossil-fuel subsidies.

Number of the Day: 18 Million
There were 18 million military veterans in the United States in 2018, according to the Census Bureau. That figure includes 485,000 World War II vets, 1.3 million who served in the Korean War, 6.4 million from the Vietnam War era, 3.8 million from the first Gulf War and another 3.8 million since 9/11. We join with the rest of the country today in thanking them for their service.
Chart of the Day: Dem Candidates Face Their Own Tax Plans
Democratic presidential candidates are proposing a variety of new taxes to pay for their preferred social programs. Bloomberg’s Laura Davison and Misyrlena Egkolfopoulou took a look at how the top four candidates would fare under their own tax proposals.
