If we are able to make superconductor magnets, create a fusion reactor and as a same time have lossless transmissions of power. Would it make energy extremely cheap ? Can access to energy become free and delivered as a commodity by countries to attract businesses and taxpayers ? This would be mind blowing, with this and automation/robotisation of work, life as we know it today will seam very ancient for next century generations. Also, are there other blocking points for inertial confinement fusion ? Would it also make solar power and wind farm pointless ?
