Reply to comment by Flowchart83 in I have finally completed the Solar System! No telescope and no equatorial mount. Just DSLRs, a fixed tripod, stacking and patience! by andrea_g_amato_art
It was just some random comment on reddit. I did find a discussion of the concept here though: https://forum.nasaspaceflight.com/index.php?topic=45398.0
They estimated 10GW, which is a couple nuclear powerplants. By the time you're running transmartian cables, you'll have the infrastructure to make big nuke plants. The magnetic field needs to be big, not necessarily strong.

Never say never. Apparently someone did the math and it would only take <100 coils around the planet and about 100 kilowatts to make enough of a magnetic field for protection.

Reply to comment by [deleted] in How do fusion scientists expect to produce enough Tritium to sustain D-T fusion (see text)? by DanTheTerrible
The amount of lithium you'll be consuming to breed tritium is orders of magnitude less than you think. One ton of duterium fused with one ton of tritium produces the same energy as 29 billion tons of coal.
