Reply to comment by djc1000 in [OC] Cost of Carbon Zero - Historical Look At U.S. Funding of Fusion Energy by Metalytiq
I don't see your criticism of the y axis, looks linear to me. I see little reason why the top graph and bottom graph must have the same scale.
On the other hand, this graph doesn't show what the title says it shows, and it is devoid of context: surely research on solar and wind count as "cost of zero carbon". Surely so also does research into emission reduction. And surely the cost of zero carbon is far less than the cost of not reaching zero carbon.

Judging by your own source, looks like OP posted the latest quarterly data from 30 September, you've quoted annual data.

Reply to How do impurities affect superconductivity? by Infferno122
Really depends on the impurity and the material.
Some increase or decrease the critical temperature. Some affect the critical magnetic field (see Ta or Ti in Nb3Sn) by changing the normal state resistance. You can also increase the amount of current that can pass through the material by increasing the number of microstructural features -- smaller grains, say, or bits of non-superconducting material.
