On Tuesday, the PBS historical series American Experience will premiere its latest documentary, "Tesla." No, it's not about the electric car company. It's about Nikola Tesla, the electrical engineer whose experiments and inventions moved electronics into the modern era. Tesla was a wacky guy with some far-fetched ideas, but many of theories about how electricity could work would eventually prove to be dead on.

Take, for example, his vision of wireless transmission of electrical currents. As you can see in the exclusive clip above, Tesla thought we'd one day be able to send power to our appliances without using wires. Companies like Qi and Mophie are currently (pun intended) betting the bank on wireless charging tech.

It should be noted that Tesla was not always given proper credit for his discoveries. You can learn about his genius ideas, his nutty ideas, and the controversy surrounding his research on your local PBS station tomorrow.

American Experience's "Tesla" premieres Tuesday, October 18 at 9pm. Check your listings.
