> we arrive at the interesting number of 8500 GW or 8.5 TW. This power must be sustained by a distributed radiofrequency system, or by an alternative acceleration mechanism. A power source at the level of 10 TW would thus appear to be required. For comparison, the total energy consumption for the entire Earth in 2019 corresponded to a source of ∼18–20 TW.

I love the audacity of this proposal.
