Submission Statement

One of the challenges for the widespread adoption of green energy is the lack of large-scale, long-term energy storage. While lithium-ion batteries seem like a potential solution, they rely on scarce materials - often mined under poor working conditions. Furthermore, their short effective operating life and sensitivity to extreme hot or cold makes them only a subpar solutions for a green energy future. The introduction of low-price, sand-based batteries, which are able to store heat for months at a time, could offer a promising alternative.
