| Fusion, the Other Solar Power | ||
In the sun, nuclear fusion reactions combine hydrogen atoms to form helium and release a tremendous amount of energy. This process intrinsically uses water as fuel, produces a million times as much energy as coal, and has no environmental impact. Various government fusion reactor programs are working on harnessing this power, but at a pace and cost that make commercially useful energy generation unreachable. Recent breakthroughs in a form of pulsed magnetic fusion have opened new doors to useful fusion power. A commercial scale fusion energy device is possible in less than 3 years! |

| Fundamental Scaling: Size=Cost | ||
The main challenge facing current nuclear fusion concepts is the complexity and large physical scale associated with the plasma confinement and heating systems. Essentially, the more massive the system required to confine and heat the fusion plasma, the higher the cost to develop and operate. The high cost of the current fusion research (and ultimately the reactors) is primarily due to the energy density of the fusion physics. The tokamak operates at low density and long timescales necessitating a large volume to provide suitable energy for a reactor. At the other end of the spectrum, a great effort has also been spent in achieving fusion at extreme energy densities. Here, minute fuel pellets are compressed to fusion conditions by a huge array of inefficient, high power lasers. There is a relatively unexplored region in reactor size and plasma energy density that lies between these two extremes that could avoid these difficulties. The Fusion Engine aims to bridge this gap with both magnetic and inertial fusion formation. |
