Mateo’s parents are thinking about investing money to help develop a new fusion power plant. Which issue is most important to co
Tasya [4]

Answer:

D) Fusion requires high temperatures and pressures, so how have they reduced the energy cost for it?

Explanation:

Fusion requires high temperatures and pressure for initiation of reaction . There is no chain reaction in it so there is no problem of controlling the problem . On the other hand , the reaction tends to stop as soon as temperature goes down due to heat getting dissipated . There is no problem of fuel as its fuel is deuterium which is present in nature in large amount . The question which is pertinent is that the cost involved in attaining so high temperature is very high so is it cost effective to produce energy by incurring so much of cost . Producing energy by using so much of energy in the beginning appears to be preposterous.
