Just in case anyone is interested, here's a quick table of magsail radiuses and energy requirements.
Code:
| Size Radius Energy|Size Radius Energy|Size Radius Energy|Size Radius Energy|
| (SM) (miles) (PPh) |(SM) (miles) (PPh) |(SM) (miles) (PPh) |(SM) (miles) (PPh) |
+--------------------+-------------------+-------------------+-------------------+
| +3 10.95 0.18 | +5.5 48.99 0.82 | +8 200.0 3.33 | +10.5 894.4 14.91 |
| +3.5 15.49 0.26 | +6 63.25 1.05 | +8.5 282.8 4.71 | +11 1095 18.26 |
| +4 20.00 0.33 | +6.5 89.44 1.49 | +9 346.4 5.77 | +11.5 1549 25.82 |
| +4.5 28.28 0.47 | +7 109.5 1.83 | +9.5 489.9 8.16 | +12 2000 33.33 |
| +5 34.64 0.58 | +7.5 154.9 2.58 | +10 632.5 10.54 | |
* A spacecraft cannot be given a space sail if its SM exceeds its TL.
