Thank you, Mr. Chair, and thank you to our guests.
I am the electricity guy here in terms of transportation. I view what you're suggesting as a kind of stopgap between gasoline and electricity, because eventually, that's what it's going to have to be. By 2050, the goal is to reduce our carbon dioxide emissions by 75%, not 20%, so we need to either stop travelling or use a different source of energy for our transportation needs. The only one currently that provides something like a 75% reduction is electricity.
In the meantime, there are some forms of transportation in this country that aren't easily convertible to electricity. One of them is in the marine industry, and the other is the rail locomotive. Is there any research or development on either propane or natural gas rail vehicles or large ocean-going or Great Lakes freighters?
