The power of the Sun

This video was pretty cool until the end. “Harness the power of the Sun”? This torch emits 2,300 lumens from a battery that lasts 30 minutes. The Sun? About 98,000 lumens, equivalent to 100 billion megatonnes of TNT blowing up per second for 9 billion years. This is also a chance to marvel at the hypernova, a.k.a. the superluminous supernova: a few billion billion megatonnes of TNT per second, a.k.a. 10 million Suns blowing up per second. It’s the hypernova that actually harnesses the power of the Sun.
