Final answer:

The main obstacle to developing fusion reactors is the inability to withstand the extremely high temperatures necessary for fusion reactions.


Explanation:

Fusion reactors have not been developed and built primarily due to the extreme challenge of achieving and maintaining the very high temperatures exceeding 40,000,000°C required to initiate fusion reactions. Current materials are unable to withstand these temperatures, making it unfeasible to harness nuclear fusion for energy production at this time.
