There are several teams working on a dense plasma focus design for fusion rather than the large and expensive tokamak or laser designs. What I like about dense plasma focus is if it works, little or no neutrons (bad radiation), the apparatus is the size of a garage, extremely cheap for a power plant. As far as I am aware, these guys are the closest to achieving a fusion power plant with dense plasma focus: http://lawrencevilleplasmaphysics.com/
