Hello Professor!!!
As a welding instructor myself, I tend to "marry" both types of learning materials together for better comprehension...
Then again, this is just my own personal method of "madness" IMHO.
On another note, a US senatorial delegation is heading down to Brazil in order to take a look at your sugar cane ethanol producing plants. They were invited by the government of Brazil.
Well, I for one think it's a long overdue move on the part of our own government to finally get serious about pursuing alternative and renewable sources of energy in order to reduce our dependence of foreign oil.
We're finally paying attention to Brazil!!! Mainly from the recent (last year) "60 minutes" piece shown here on television about the success of Brazil's "Alchohol" alternative automobile fuel plants...
When the folks in Brazil mentioned how much less they were paying on average for this type of fuel as opposed to the traditional gasoline, well let's just say that we were convinced that we had to pursue this further...
Question: I wonder what types of metals are being used in the construction of these plants?
I must say: Not bad for a third world country, Brazil that is!!!
