We do have simulations on this, and we're in the process of putting out numerous papers in several different journals. And again, we're not necessarily saying our machine will be sufficiently better than Sandia's. For starters, we don't expect to come close to achieving breakeven, and we're not claiming we'll achieve that. Our primary goal is to investigate Li-D reactions and its applications for propulsion due to the scarcity of research on that subject. The results obtained from this research can then help Sandia and other labs achieve their own research goals. They in turn can help us from whatever they uncover. Again, collaboration is vital for fusion research.
