Former Mythbusters Host Adam Savage Goes Hands-On with a Screen-Used Mr. Fusion DeLorean Time Machine Prop

Former Mythbusters host Adam Savage goes hands-on with a screen-used Mr. Fusion DeLorean time machine prop. This fictional power source was introduced at the end of Back to the Future and prominently featured in Part II and Part III, designed to convert household waste into the 1.21 gigawatts needed to power the DeLorean’s time circuits.

Did you know that it was originally built from a modified Krups coffee grinder? Adam showcases its detailed craftsmanship and its significance to the franchise. However, it does not appear in Back to the Future Part III in a functional sense—by the time Marty arrives in 1885, the DeLorean’s Mr. Fusion unit is still present but non-operational for time travel due to a lack of compatible fuel in the Old West.

Only a handful of Mr. Fusion props were made for the films. The one Adam Savage examined in this video video is an original, not a replica, making it a prized artifact. Its condition reflects wear from filming, adding authenticity. Unlike the flux capacitor or the DeLorean’s fiery tire trails, Mr. Fusion didn’t require elaborate special effects. Its “activation” was implied through editing and sound design.
