“Based on my experience, I am writing this public letter to express my fear that you have made an enormous mistake by proposing to build a sodium-cooled Small Modular Reactor (SMR) in Wyoming. Mr. Gates, your atomic power company Natrium (the Latin word for sodium), is following in the footsteps of a seventy-year-long record of sodium-cooled nuclear technological failures. Your plan to recycle those failures and resurrect liquid sodium again will siphon valuable public funds and research from inexpensive and proven renewable energy alternatives. Moreover, spending public funds on Natrium will make the global climate crisis worse, not better!”
