Controlled fusion requires > 14million celsius

The theoretical maximum temperature is also called the Planck temperature, and it was the temperature of the Universe at the instant of its creation in the Big Bang. This temperature is 1.42 x 10^32 K.
By comparison, the Sun's corona is at a temperature of 5 million Kelvins, and the maximum temperature at the core is 13.6 million Kelvins. Nuclear fusion occurs at the core, so temperatures of 100 million Celsius (approximately the same as Kelvin at this scale) would not be required for fusion. However, the pressure at the center of the Sun is incredibly high. At lower pressures, higher temperatures would be required to achieve fusion.

100 Million celsius is not needed for fusion. Fusion happens quite happily in the sun at only 14 Million Celcius

theoretically, temperature ranges to infinity FROM infinity!
