Energy question of the week: Can lasers unleash the Sun's power to create a fusion reactor?

15. March 2010, 07.33
Low-cost, safe, climate-friendly and inexhaustible – many energy experts view nuclear fusion as the power source of the future. Having said that, scientists believe that it will take another 40 to 50 years before the first fusion power station is in operation. Hot plasma, trapped within a strong magnetic field is currently the most promising way forward, and Europeans in particular are focusing on this concept. However, might it not be much simpler and quicker to find a way to unleash the fire of the Sun by means of powerful lasers that American physicists are working with?
