Just read this from some website:

"Energy from a fusion reactor has always seemed just out of reach. It’s essentially the process of producing infinite energy from a tiny amount of resources, but it requires a machine that can contain a reaction that occurs at over 125,000,000 degrees. However, right now in southern France, the fusion reactor of the future is being built to power up by 2019, with estimates of full-scale fusion power available by 2030."

 

The idea of infinite energy seems like it would violate the laws of scarcity, and the fact that energy is neither created nor destroyed. If it became infinite, this law would be proven wrong. Being that I am in no way a scientist or well-versed in the field of chemistry or physics, I am wondering if someone can explain if fusion power is total bull shit or not.

 

Thanks

Check out the "Polywell". From what I've read, it seems to have a better chance of providing a fusion breakthrough than ITER. Unfortunately, it's being funded by the US Navy.

I don't think that anyone expects that to refute the second law, or to imply that infinite energy is likely, but that advances in fusion energy will yield greater efficiencies over time. Fusion simply returns low EROI relative to inputs currently, but large-scale experiments like the one in France are simply steps toward a possible viable energy solution in the future. 125 million degrees is hardly cold fusion, but it's a step and will result in efficiencies over time that might give way to having a Mister Fusion powering your car or home.

It's not actually infinite but rather virtually infinite.

The amount may be large or "virtually infinite" but its usability is very finite.  First is the issue of turning that much heat into electricity or some other useable form.  Then comes the hard part of getting it to a consumer.  Line loss is huge in power transmission and converting electricty into other forms of fuel is innefficient, costly and some cases can be extremely dangerous.  So even with fusion reactors around there will still be scarce energy.
