The following page on the JLN Labs website details a series of replication attempts that allegedly show excess heat production. Looking back at these experiments are a blast from the past - I remember reading about them so long ago it feels like ancient history. Although the powder-gas-plasma systems and pure plasma systems may seem more promising, if CF can be proven with a system such as these, I wonder if would be worth the effort to attempt replicating them. Of course it would take up money, time, labor, and other resources that in my opinion could be devoted to building a pure plasma based system like Rossi's Quark.
The first thought that comes to mind is that these look like far higher powered versions of JohnyFive's experiments. Do any of you have any comments?
