As I understand it, powering a significantly larger DPF fusion reactor is going to take some serious power source engineering breakthroughs. Once the current generation goes into production we may be able to attract both the talent and other resources to tackle challenges like Cap 2.0, Switch 2.0, HV Buss 2.0, and so forth. The key thing here is that these are 2 entirely separate designs and technologies sharing the same theoretical underpinnings.
