What's PR?  Spending 1/6th of the entire cost on public relations seems like too much.
Not if it prevents a Windfall Profits Tax !

And what is NOT to love about this project ?  IMHO, Shell PR & DC lobbyists would be drooling over this !

The average American would think that it is producing 10% or 15% of the oil that we need.  The "Light at the end of the tunnel".  Proven reserves would skyrocket (since this was making a profit), it is just that the production rate was quite low and it scalability depending upon wind saturation of the local grid.  Return on capital would also be low but profitable.
