This pack contains advanced electrically powered engines including electrostatic ion engines, plasma engines and VASIMR engines.
The engines run on stock Xenon Gas and two new resources: Lithium and Argon Gas. A full tank set is provided for the new fuels, plus new Xenon tanks. Make sure to have enough power to run them, as shown in the VAB. Solar power can work with the smaller engines, but the larger, more advanced engines will likely require you to use other power sources, like nuclear reactors from Near Future Electrical.
