Laser target fusion

I see that Curtis et al of Colorado State University claim a record production of 2 million fusion neurons per Joule of laser light from a nanowire target array. (Micro-scale fusion in dense relativistic nanowire array plasmas, Nature Communications, published online 14 March 2018) This appears to be based on my electron space charge ion heating mechanism.
