"The deuterium in a single cubic meter of seawater contains the as much energy as nearly 1,400 barrels of crude oil - enough to supply the civilizaton's energy needs for hundreds of millions of years - until long after the Sun itself has flamed out."

What does that sentence mean? It seems like a claim that the energy of 1,400 barrels of crude oil is enough to sustain civilization for a long time, but that seems implausible to me. Also, off by an order of magnitude on the timeline for the sun burning out.

Whenever I read stuff like this now I start to get paranoid that this is written by GPT-3.

That's 1 cubic meter. We have a lot more seawater?

There is a lot of water out there.

* Total ocean volume: 1.3e18 cubic meters, 1.8e21 oil barrels equivalent [1]

* Current oil consumption: 35,442,913,090 barrels per year [2]

* Oil share of total energy consumption: 34% [3]

* Number of years of reserves at current consumption levels: 17,577,561,935 years.

Assumptions:

* Consumption levels are flat, definitely false.

* Energy cost of retrieval: 0, definitely false.

* Retrieval rate: 100%, definitely false, as the concentration dilutes over time.

The US alone consumes tens of millions of barrels a day according to the US govt[1] so this claim of "1,400 barrels of crude oil - enough to supply the civilizaton's energy needs for hundreds of millions of years" is very far off the mark.

I think GPT-3 would've probably written it more accurately.
