There is an ion thruster that lifts its power supply against Earth's gravity. It is called the Self Contained Ion Powered (propelled) Aircraft or Ion Propelled Vehicle, US Patent 10,119,527. There are over 30 videos of it in flight online. It was verified to lift its power supply by the host of NPR and plenty of others. The website for it is at URL deleted It can fly for nearly 2 minutes at a time so far. It has some design changes over previous ionocrafts (and lifters), that make it operate on much less power. It is also very lightweight and has a specialized power supply.
The craft flies by adding electrons to O2 molecules, thereby producing negative ions. This is contrary to some popular diagrams of the process. Oxygen has a high affinity for electrons, that is why it is called an oxidizer. "Corona," is mostly produced by air molecules when they lose electrons also called de-excitation. At low energy levels very little nitrogen is energized. When an EAD craft is designed to primarily add electrons to ambient O2 molecules, it mostly excites them, and therefore produces far less corona. O2 molecules can hold on to an extra electron for up to minutes at time. Very little ozone is produced at low wattages and currents. The less corona that is produced the more efficient these vehicles are, according to my lift measurements and corona camera footage video.
