Answer:
b. False
Explanation:
The project would require energy in order to be able to draw energy from its sorrounding, meaning it will require more energy input compared to other systems. Also, drawing heat energy from the envoirment might not be a reliable energy source. All this also counteract energy conversion law.

Explanation:
I got it right on edge. have a good day!
Answer:
86 mm
Explanation:
From the attached thermal circuit diagram, equation for i-nodes will be
Equation 1
Similarly, the equation for outer node “o” will be
Equation 2
The conventive thermal resistance in i-node will be
Equation 3
The conventive hermal resistance per unit area is
Equation 4
The conductive thermal resistance per unit area is
Equation 5
Since 
is given as 100, 
is 40 
is 300 
is 25
Substituting the values in equations 3,4 and 5 into equations 1 and 2 we obtain
Equation 6
Equation 7
From equation 6 we can substitute wherever there’s 
with 3000L+40 as seen in equation 7 hence we obtain
The above can be simplified to be
-3000L=1.665-260
Therefore, insulation thickness is 86mm
