Why is nuclear fusion difficult to carry out?                           Or Why is nuclear fusion not possible in a laboratory?                

Answer:

                Nuclear fusion requires very high temperature of \[\text{1}{{0}^{\text{6}}}-\text{ 1}{{0}^{\text{7}}}\text{K}\]. This temperature is attained by causing explosion due to the fission process. Moreover, no solid container can withstand such a high temperature.
