Nuclear fusion powers our sun and all the stars in the night sky; if harnessed on earth, it could be the ultimate energy source: safe, clean, and with plentiful fuel.
Large scale reactors continue to run into technical hurdles and delays--and costs continue to increase. Smaller, simply connected systems allow for faster innovation at low cost. Moreover, smaller power plants can be utilized in more places across the globe.
Commercial fusion energy will ultimately provide energy independence, national security, and new jobs in the emerging clean-tech market sector.
