I think your calculations must be out.
The work achieved (lifting some tons of rocket) is orders of magnitude less work than the power extracted from falling water (hydro, thousands of tons per second).
And the heat output of burning hydrocarbons and nuclear reactions worldwide were concentrated into a few rocket nozzles, that would be rather mind boggling!
For the record, the saturn V rockets operated at 120GW. Which is also close to a terawatt.
Read the two comments (one I replied to and the one it relied to) for context. My comment wasn’t intended to be free standing on its own.
If you don’t need all the falcon’s fuel, you don’t need nearly as much thrust either.
Sure, just something that can generate a terawatt of power.
Cold fusion maybe?
Does Adobe even still support that?
25th anniversary edition in fact...

7,500,000,000 millinewtons = 7.500 Meganewtons
1 Watt = 1 Newton-meter/second
You're missing some values.
The missing value would be the 12mN/kW that the top post opened with. Getting 7.5 MN output thrust with that conversion ratio requires 625GW of input power.
So doing some napkin math with the article’s 12mN/kW, that’s close to a terawatt. For reference, I think worldwide electrical power generation capacity is around 10x that.
