I find that Berkshire Hathaway offers low-risk exposure to a novel lithium extraction technique being developed in the Salton Sea region of California. With plenty of operation profits and infrastructure in place, the technology has a large likelihood of success in developing an important US-based lithium source for BRK to leverage. This can be in the form of their own in-house battery applications, or bulk sales to EV and Energy Storage names. While unlikely to impact BRK financials for at least five years, the high demand for lithium offers close to limitless potential, and production capacity will be the limiting factor.
