The Deflated Helium Industry
Aug 20, 2013

Although a fusion reactor would indeed make helium, it appears that - at best - there would only be enough to serve its own cooling needs.
A paper by Bradshaw A.M. and Hamacher T., "Nuclear fusion and the helium supply problem", Fusion Engineering and Design (27 February 2013) noted these points:
Fusion power plants will require helium as cryogenic medium and as coolant.
High losses are expected: for a power plant like DEMO ≈ 2 t p.a.
The same power plant is expected to produce only ≈0.6 t p.a.
Global helium resources are finite: fusion will therefore exacerbate an already difficult situation.
The “back-stop” technology will be the extraction helium of helium from the atmosphere.

Jean Pisani-Ferry

The Trump administration’s economic policy is a strange cocktail: one part populist trade protectionism and industrial interventionism; one part classic Republican tax cuts skewed to the rich and industry-friendly deregulation; and one part Keynesian fiscal and monetary stimulus. But it's the Keynesian part that delivers the kick.
