Talk:Heavy ion fusion

A fact from Heavy ion fusion appeared on Wikipedia's Main Page in the Did you know column on 21 April 2021 (check views). The text of the entry was as follows:

Did you know... that although John Foster long ago described heavy ion fusion as "the conservative approach" to a working fusion reactor, no large-scale system has ever been built?

This substantial article is new enough and long enough. The hook facts are cited inline, the article is neutral, and I detected no copyright or other policy issues. A QPQ has been done. Cwmhiraeth (talk) 08:51, 15 April 2021 (UTC)[reply]

Failed to obtain cited data from reference[edit]

In order for the fusion reactions to produce enough energy to match the original energy of the laser, it will have to produce at least 4 MJ, and for practical reasons, at least three times that, implying the ratio of input laser energy to output fusion energy,[c] or gain, has to be on the order of hundreds or thousands. To date, the record on NIF is 1.3 MJ of fusion from 2 MJ of laser output,[5] from 422 MJ of electricity, so it is extremely unlikely the current approach could ever be used for power production.[6]

The values 4 MJ, 2 MJ and 422 MJ is not obtainable from the cited references. The sandias web page does not give these numbers and the paper linked from the sandias web page 404's. I discovered this when going through the edits of 198.102.151.242, which seems to be occasionally vandalizing (e.g. in this edit) · · · Omnissiahs hierophant (talk) 19:14, 8 January 2022 (UTC)[reply]
