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.
Marco Rubio Says There’s No Proof Tax Cuts Are Helping American Workers
Sen. Marco Rubio (R-FL) told The Economist that his party’s defense of the massive tax cuts passed last year may be off base: “There is still a lot of thinking on the right that if big corporations are happy, they’re going to take the money they’re saving and reinvest it in American workers,” Rubio said. “In fact they bought back shares, a few gave out bonuses; there’s no evidence whatsoever that the money’s been massively poured back into the American worker.”
For Richer or Poorer: An Updated Marriage Bonus and Penalty Calculator
The Tax Policy Center has updated its Marriage Bonus and Penalty Calculator for 2018, including the new GOP-passed tax law. The tool lets users calculate the difference in income taxes a couple would owe if filing as married or separately. “Most couples will pay lower income taxes after they are married than they would as two separate taxpayers (a marriage bonus), but some will pay a marriage penalty," TPC’s Daniel Berger writes. “Typically, couples with similar incomes will be hit with a penalty while those where one spouse earns significantly more than the other will almost always get a bonus for walking down the aisle.”
Trump Administration Wants to Raise the Rent
Housing and Urban Development Secretary Ben Carson will propose increasing the rent obligation for low-income households receiving federal housing subsidies, as well as creating new work requirements for subsidy recipients. Some details via The Washington Post: “Currently, tenants generally pay 30 percent of their adjusted income toward rent or a public housing agency minimum rent not to exceed $50. The administration’s legislative proposal sets the family monthly rent contribution at 35 percent of gross income or 35 percent of their earnings by working 15 hours a week at the federal minimum wage -- or approximately $150 a month, three times higher than the current minimum.” (The Washington Post)
New Push for Capital Gains Tax Cut
Anti-tax activists in Washington are renewing their pressure on lawmakers to pass new legislation indexing capital gains taxes to inflation. The Hill provided an example of such indexing that Grover Norquist recently sent to Treasury Secretary Steven Mnuchin: “Under current policy, someone who made an investment of $1,000 in 2000 and sold it for $2,000 in 2017 would pay capital gains taxes on the $1,000 difference. But if capital gains were indexed, the investor would only pay taxes on $579, since $1,000 in 2000 would be equivalent to $1,421 in 2017 after adjusting for inflation.” Proponents of indexing say it’s just a matter of fairness, but critics claim that it would be just another regressive tax cut for the wealthy. Indexing would cost an estimated $10 billion a year in lost revenues. (The Hill)
Bernie Sanders to Propose Plan Guaranteeing a Job for Every American
Sen. Bernie Sanders (I-VT) is preparing to announce a plan for the federal government to guarantee a job paying $15 an hour and providing health-care benefits to every American “who wants one or needs one.” The jobs would be on government projects in areas such as infrastructure, care giving, the environment and education. The proposal is still being crafted, and Sanders’ representative said his office had not yet come up with a cost estimate or funding plan. Sen. Kirsten Gillibrand (D-NY) last week tweeted support for a federal jobs guarantee, but Republicans have long opposed such proposals, saying they would cost too much. (Washington Post)
