Dr. Shaw, thank you very much for being with us today.
I have a couple of questions for you. To start with, there is a clear price advantage for natural gas right now. Your graphs show that. All of the public data confirms it.
There's a capital cost involved in switching over to natural gas powered vehicles of any kind, whether it's the infrastructure within the vehicle or the fuelling station. We can only determine whether or not that infrastructure investment is worthwhile by looking at the payout in savings on fuel prices over the long term, as represented by the gap per million BTU between gas and oil.
Here's my question. Are you sure that this price advantage is here for the long run? Or are there factors like the shipping of LNG to big markets like Asia that could increase natural gas prices in North America and eliminate that price advantage, thus undermining the return on investment on the infrastructure side?
