Abstract
Beam fusion with light ions resulted in the best fusion gains ever and has achieved the level to build a hybrid reactor at a price comparable to the conventional breeders, but safer than these. The reason that this could not occur earlier was the argument of cross sections by which any beam fusion concept for the last 30 years was condemned. Induced by the experimental breakthrough of beam fusion, the complicated physics is discussed including recent developments of electrostatic double layer effects in plasmas. An interpenetration model for self-sustained fusion combustion in solid DT is presented with a threshold of 2 × 107 Joules/cm2. Present days CO2 lasers may initiate this boots trap process using nonlinear force effects to generate space charge neutral ion beam densities exceeding 109 Amp/cm2. From this example and from the experience of the development of fusion research, the scientific development is considered and a motivation is given for rethinking about the fusion programs toward an earlier achievement of fusion energy.

If solar energy could provide 10% of all energy needed, this still would be of a gigantic volume and a very profitable big business; there seem to be fundamental limits, however, that the concentrated low cost main energy for producing the fertilizers for feeding the present or even growing population cannot come from solar energy.

The experimental breakthrough in beam fusion [2] should be seen similar to the discovery of the transistor effect with the very unpredicted long life time of minority carriers in germanium single crystals, later explained as an anomaly of the multivalley band model; or similar to the first ruby laser developed contrary to the expected laser action of sodium lines.
