Talk:Magnetic sail/Archive 1
Test manual archive[edit]
On my own talk page I did a test with Cluebot III and had to type some text here.
Seems like it is getting deleted by a bot, or 02:56, 24 October 2023 Liz talk contribs.
superconducting ?[edit]
A magnetic sail or magsail ... a large loop of superconducting wire
Does it have to be superconducting ?
Given the low field strenghts needed, I guess not, but then it constantly drains energy from its onboard electric power source, dissipating it in loop by Ohm's law, shortening the total time of acceleration (and thus limiting maximal velocity) of spacecraft. Besides, wire would have to be thicker and therefore heavier. Dmcdysan (talk) 03:25, 24 October 2023 (UTC)
