Molten Metals to Green the Grid

Living on Earth
The World

The U.S. government is investing hundreds of millions in high risk, high reward research that could produce what it calls “transformational technology” that changes our energy future. Host Jeff Young visits the lab of a MIT scientist who got support to develop batteries made from molten metals. If it works, it could allow for massive storage of renewable energy for times when there’s not enough sun or wind.

Do you support journalism that strengthens our democracy?

At The World, we believe strongly that human-centered journalism is at the heart of an informed public and a strong democracy. We see democracy and journalism as two sides of the same coin. If you care about one, it is imperative to care about the other.

Every day, our nonprofit newsroom seeks to inform and empower listeners and hold the powerful accountable. Neither would be possible without the support of listeners like you. If you believe in our work, will you give today? We need your help now more than ever!
