Fusion produces no greenhouse gases, and, unlike nuclear fission, it does not produce long-lived radioactive waste.
FORBES: A Challenge to America: Develop Fusion Power Within a Decade
Perhaps it's true that Einstein was referring to nuclear fission compounding at a rapid rate--e.g.
Nuclear fission in the context of the span of history is, like the ancient discovery of fire, game-changing.
FORBES: Post Fukushima-- burn more coal and oil, and hire more engineers not regulators
There are some characteristics of a nuclear fission reactor that will be common to every nuclear fission reactor.

Xenon-133 is a radioactive noble gas produced during nuclear fission that poses no concern at the detected level.
Nuclear fission, generally fuelled by uranium or plutonium, heats up water which evaporates.
The document called for increased in areas such as solar power, biofuels, nuclear fission and carbon capture and storage (CCS).
Think of nuclear fission: it generates useful energy but if it runs out of control you get a cataclysmic explosion.
ECONOMIST: Why Germany seems not to want a quick fix for the euro crisis
Nuclear fission avoids using large quantities of fossil fuel for energy but is very contentious because it produces radioactive waste.
BBC: Impact of global warming may be severe and wide-ranging
The Earth is warmed naturally by its own nuclear fission reactors within and also by the sun, that big nuclear fusion reactor.
Its breakthroughs ran the gamut from helicopters to computing to nuclear fission.
FORBES: Globalism and Technology: A Hidden Misconception That Dooms the U.S. Economy
Rather than create electricity by heating water and turning a turbine, Wilson's new reactor would use nuclear fission to produce energy from molten salt.
Today, most alternative energy technologies that are discussed--wind, solar, tides, waves, clean coal, nuclear fission and, perhaps one day, fusion--are useful only for making electricity.
Since China and India will be industrialising heavily this century, there is no other option but to consider nuclear fission power plants for electricity generation.
Reactors that exploit nuclear fission (in which energy is generated by splitting uranium atoms) have produced thousands of tonnes of spent fuel and other radioactive by-products.
Thermoelectric coupling uses heat from the decay of a radioactive fuel (as opposed to the full-scale nuclear fission which powers a reactor on Earth) as its energy source.
ECONOMIST: A more efficient way to make electricity in spacecraft
Given its inherent risks, nuclear power has always been an exercise of mind over matter, in which human intellect seeks to harness the power of nuclear fission of radioactive materials.
The energy release from nuclear fission is roughly a million times greater per unit weight than fossil fuels, which is why nuclear fission is such a compelling long term energy source.
FORBES: Explainer: What Caused The Incident At Fukushima-Daiichi
Our government, the catalyst for innovations from nuclear fission and space exploration to the Internet, faces tough strategic choices if we are to maintain our position as the world's innovation hub.
The third selling point: Hydrogen could, in principle, deliver energy independence to every nation because it can be derived using any number of sources-including oil, natural gas, nuclear fission, coal, hydroelectric power and wind.
The device's primary source of neutron radiation was the radioactive element californium, but the stream of neutrons produced by the californium was multiplied by passing it through a lattice of highly enriched uranium U-235, whose nuclear fission released additional neutrons.
The Daily Yomiuri continued to follow the government's moves to investigate the accident with a story about how Japan's Science and Technology Agency plans to exactly re-create the nuclear fission chain reactions that occurred at the plant--presumably under safer conditions.
CNN: ASIANOW - Asiaweek | Daily Briefing: New Stability in India?
The growing mountain of nuclear waste from fission reactors, however, has recently rekindled interest in the scheme.
However, while mining helium-3 from the moon will be one challenge, extracting energy from it is another, as it relies on nuclear fusion, rather than fission used in today's nuclear reactors.
The good news is that the big names in nuclear energy -- like Areva, Hitachi, General Electric and Toshiba -- have recently been joined by a bevy of high-tech start-ups seeking to develop advanced nuclear-reactor designs for both fission and fusion energy production.
This is why the idea of nuclear fusion is cool as opposed to fission, if this is possible.
There are various advantages cited for this type of reactor, including the claim that it can be stopped easily if things get out of hand, and that it produces less long-lived nuclear waste than the uranium-fuelled fission reactors that are currently in common use.
About 2 billion years ago, uranium rocks at a site in Oklo, Gabon, experienced such compression that they underwent fission reactions much like those that occur in nuclear reactors.
