Summary
The author concludes that if steel-manufacturing plants could feed the heat they produce into thermo. generators, they would save money by reducing electric bills. Why? Because the process of making steel makes a lot of heat that currently goes to waste. Thermo. generators can convert heat into electricity.
Notable Assumptions
We know that thermo. generators can convert heat into electricity. And we know that there’s a lot of waste head from making steel. If the generators could convert the heat into electricity, electric bills might be reduced. But does that prove there will be overall cost savings? There might be other costs to take into account — costs of installing, running, and maintaining the generators, for example. The author’s assuming that these other costs associated with the thermo. generator would not outweigh the cost savings from reduced electric bills.
A
There is no other means of utilizing the heat produced by the steel-manufacturing process that would be more cost effective than installing thermophotovoltaic generators.
The author never suggested that thermo. generators would be the most cost effective means of using the currently wasted heat. Even if there were more cost effective means, the thermo. generators could still be one way to save money.
B
Using current technology, it would be possible for steel-manufacturing plants to feed the heat they produce into thermophotovoltaic generators in such a way that those generators could convert at least some of that heat into electricity.
The conclusion is based on the hypothetical situation in which the plants could feed heat into thermo. generators. If that’s possible, the author says, then it would save money. But this doesn’t require an assumption that the hypothetical situation is in fact true with current technology. Even if current tech. can’t do it, we can still argue about what would happen IF it were possible.
C
The amount steel-manufacturing plants would save on their electric bills by feeding heat into thermophotovoltaic generators would be sufficient to cover the cost of purchasing and installing those generators.
Necessary, because if it were not true — if the savings on electric bills would NOT be enough to cover the cost of purchasing/installing the generators — then the generators would not result in “saving money.” The savings from electric bills would be offset by the other costs.
D
At least some steel-manufacturing plants rely on electricity as their primary source of energy in the steel-manufacturing process.
Not necessary, because as long as steel plants use electricity at all, the author’s argument can still work. There can still be savings on electric bills, even if electricity is not the primary source of energy for any steel plants.
E
There are at least some steel-manufacturing plants that could greatly reduce their electricity bills only if they used some method of converting wasted heat or other energy from the steel-manufacturing process into electricity.
