Thank you.
First of all, I'd like to welcome Dr. Hunter to ENVI. Dr. Hunter is a much respected and valued member of our community in Carleton. I was one individual who benefited from one of his famous tours of his retrofitted home. Another piece of information I think the committee would be interested in knowing is that Dr. Hunter is one of the leaders who delivered the Canadarm for the space shuttle.
It is a great honour to have you here, sir, and I'm grateful that you've turned your attention, after conquering space, to conquering space heating.
Now, before you began your retrofit, you were living in a conventionally heated home. Was that home heated with natural gas, propane or...?
