You're about to hear a lot about #NuclearFusion. I've followed the field for years & can offer context. Top line:
- NIF's "breakeven" does not generate more power than it consumes
- NIF is not a model for a commercial fusion reactor
- This news is a big deal all the same. 1/n

Fusion researchers measure fusion output in "Q," the ratio of power produced to power needed to maintain the fusion plasma. NIF has exceeded Q=1.
Breakeven, right? Er, the accounting is not so simple, as Charles Seife explains. 2/n theatlantic.com/technology/arc… #fusion #NIF

The power that goes into igniting a fusion pellet is much less than the total amount that NIF consumes. "Breakeven" comes nowhere close to covering all of that consumption! A useful fusion power plant would require anything from Q=5 to Q=100. 3/n

At yesterday’s #FOMC meeting, the Committee revealed more expected tightening and further steps toward #tapering #asset purchases than they had previously. We see these as steps in the right direction.
Yesterday’s @federalreserve statement and press conference suggest that the Committee believes progress has been made toward its goals, but that there’s still some room to go to hit the recently re-defined objective of maximum #employment.
Still, it’s now time to set up for the end of this long-running #EmergencyPolicy-focused movie.
