No. The full electric vehicle is the only vehicle that doesn't work with flywheels. We work with any other type of internal combustion engine and any fuel. We are engine or fuel agnostic.
To address the point more specifically, great marketing positioning from the industry is that the battery that's plugged in is either coal, nuclear, or hydro-based electricity that does it. We don't wave a magic wand and derive it out of thin air. Typically, it's nuclear or coal-fired electricity that's going into that. So the notion that a full electric vehicle is carbon neutral is ridiculous, quite frankly.
