Fusion power is quite a bit further along than 45 years ago. We're in the process of building ITER, with ignition expected in 2020. The main problem for fusion power is the utter lack of funding it receives:
Uh huh. Exactly what will they have accomplished by 2020? Ignition? Who cares? Based on their own timeline the earliest possible date for a commercial fusion reactor is 2050.
Do you have a more credible source than a website from someone who claims to have received letters from aliens? There seems to enough scientific consensus that ITER will work to convince people to spend quite a bit of money on it.
The definition of "will work" has been downsized over the years.
What ITER is now claimed to do is much less than it was originally supposed to do. Originally it was supposed to be able to produce 500MW more or less continuously. That goal has been downsized to 300-500 seconds. The current record for holding a fusion reaction together is about a second. If ITAR beats that by a reasonable margin, its backers can call it a victory and go home.
