So I asked an AI how to make a lightsaber. I mean a portable meter long plasma arc generator. This was my conversation with Gemini on how to create a lightsaber. The argument here comes down primarily to the method of creation. First, you can't create a lightsaber from pure plasma unless you have the power output of a sun. You can't create a magnetic loop that contains a heated plasma for a similar reason. However, there *is* a possibility, however small that you may be create a lightsaber if you create a device that has an initial spark which a field maintains that causes the air through which the blade travels to turn into a super heated plasma.
