The two authors interviewed here are both worth reading for those who are actually interested in clean energy.

It seems clear that both approaches to solving the dirty fossil fuels problem can be and will be taken.And both approaches ARE being pursued all over the world.

The problems associated with nuclear energy do not disappear with the use of thorium. There are definitely technical challenges to overcome, but these are not brick walls.

It seems kind of silly to me that people will go on and on about how we are going to fry ourselves with CO2 emissions and then complain about the relatively modest risks that nuclear energy entails.

In the meantime, we are still waiting for the peak of oil production.

The potential reduction of current radioactive "waste" products is the most attractive benefit of the thorium cycle. This would be a world changer if it can be made practical.
It also appears to be necessary to bring on additional electric power sources to assist in the transistion away from fossil fuels.
If PV advances at 30 percent gain per year for the next 20 years, it will reach peak power equivalent to current world power production. It's average power output would be about 2/3 of current world electric use. Even with improved efficiency in panels and end use, that will not be enough. Developing countries want electric power and since a large portion of the energy from fossil fuels will be substituted by electricity, other sources will need to be brought on line, at least until solar, wind, and ocean electric power grows fully. Thorium reactors look like a likely candidate for this additional transistion power.

According to the IEA, Renewable energy is the fastest growing power sector and will pass natural gas by 2016.

Renewable energy is growing fast around the world and will edge out natural gas as the second biggest source of electricity, after coal, by 2016, according to a five-year outlook published Wednesday by the International Energy Agency.

Developing countries are building more wind, solar and hydro-electric power plants to meet rising power demand and combat local pollution problems. And the costs of renewables are falling below the cost of traditional power sources such as coal, natural gas and oil in some markets with high-priced power.

Renewable power, including hydropower, is the fastest-growing power generation sector and it is expected to increase by 40 percent in the next five years. By 2018 it will make up a quarter of the world's energy mix. "The rapid growth of renewables continues to beat expectations and is a bright spot in an otherwise bleak assessment of global progress toward a cleaner and more diversified energy mix," the report concludes.

The IEA estimates that worldwide subsides for fossil fuels are six times higher than incentives for renewables.

Thorium is an even more nascent technology than PV is. It cannot replace current power needs within the next 20 years. There still needs to be much groundwork done to get a thorium power industry up and running at the commercial level. Thorium might have many advantages over Uranium, but unfortunately Uranium has first mover advantage and an entire industry built around it already. It is going to take a lot of money and effort for Thorium to even catch up to Uranium, let along replace fossil fuels. Current enthusiasm for Thorium seems tepid. certainly nothing like the Messmer Plan.

The French prime minister, Pierre Messmer, outlined the pro-nuclear case in a speech on national television on March 6, 1974: 'France has not been favored by nature in energy resources. There is almost no petrol on our territory, we have less coal than England and Germany and much less gas than Holland ... our great chance is electrical energy of nuclear origin because we have had good experience with it since the end of World War II ... In this effort that we will make to acquire a certain independence, or at least reduced dependence in energy, we will give priority to electricity and in electricity to nuclear electricity.' The Messmer Plan, as it became known, involved a huge and sudden swing toward nuclear dependence, foreseeing the launch of 13 nuclear power plants, each with a capacity of 1,000MW, within two years.

The Messmer plan succeeded in turning France into a nuclear-powered country. In the six years to 1979, nuclear energy's share of EDF's total output rose from 8 percent to 20 percent. By 1983 it had jumped to 49 percent, and by 1990 nuclear plants were providing 75 percent of EDF's electricity. By contrast, the share produced by stations burning oil or coal fell from 53 percent in 1973 to 24 percent in 1983, and down to just 11 percent in 1990.

Nuclear scientists are being urged by the former UN weapons inspector Hans Blix to develop thorium as a new fuel.

Mr Blix says that the radioactive element may prove much safer in reactors than uranium.

It is also more difficult to use thorium for the production of nuclear weapons.

His comments will add to growing levels of interest in thorium, but critics warn that developing new reactors could waste public funds.

Mr Blix, the former Swedish foreign minister, told BBC News: "I’m a lawyer not a scientist but in my opinion we should be trying our best to develop the use of thorium. I realise there are many obstacles to be overcome but the benefits would be great.

"I am told that thorium will be safer in reactors - and it is almost impossible to make a bomb out of thorium. These are very major factors as the world looks for future energy supplies."

Hans Blix says the world should try its best to develop thorium

His enthusiasm is shared by some in the British nuclear establishment. Scientists at the UK’s National Nuclear Laboratory (NNL) have been encouraged by the government to help research on an Indian thorium-based reactor, and on a test programme in Norway.

China is going for a revolutionary approach, devising a next-generation reactor which its supporters say will enable thorium to be used much more safely than uranium.

When a uranium reactor overheats and the fuel rods can’t contain the chain reaction, as happened at Fukushima, the crisis continues. If something happened to a thorium reactor, technicians could simply switch off the stimulus which comes from uranium or plutonium in a small feeder plant and the thorium reaction would halt itself.

Prof Carlo Rubbia from Cern previously told BBC News: "Thorium will be able to shut itself off without any human intervention... You just switch off the beam.”

"There are also no long-lived waste products... We estimate that after something like 400-500 years all the radioactivity will be dissipated away."

These advantages, if they were realised, would be huge. But thorium still has many technical problems to overcome. What is more, countless billions have been ploughed into uranium-based research and development, and in the words of Mr Blix, uranium has a very deep furrow, backed by vested interests.

My Radical Plan for Small Nuclear Fission Reactors – Taylor Wilson

He is known as The Boy Who Played with Fusion and Forbes questioned Is This the Bill Gates of Energy?

Excited, he described it as a big announcement, although it might be a little bit of a surprise to those who knows his background.

His molten-salt reactor is designed to have specific parameters. It is small enough to be produced in a factory and transported to installation site. When it is fueled and sealed it runs for 30 years without refilling fuel. Its high temperature makes it possible to increase the efficiency to 45-50%.

Earlier we wrote that he has taken the step from fusion to fission. Next, he might reveal the potential of adding some thorium! Indeed, “Inside this reactor is a molten-salt, so anybody who is a fan of thorium will be really excited about this… because these reactors happen to be really good at breeding and burning the Thorium fuel cycle” Taylor explained.

He graduates high school in May and decided he was going to commercialize these technologies he has developed. He has since developed a team with some of the most incredible people he has ever had the chance to work with and he is really prepared to make this a reality.

Oh, and a final point, he aims for the same price as gas or cheaper![/quote]

Is This the Bill Gates of Energy?

Taylor Wilson, an 18-year-old nuclear energy entrepreneur. A Nevada-based scientific prodigy who built a nuclear fusion reactor in his parents’ garage at the age of 14, Wilson held court on the fringes of the conference, confidently dispensing wisdom on everything from nuclear terrorism to the future of the world energy industry. Named the Intel Young Scientist of the Year in 2011 and the recipient of a $100,000 fellowship funded by PayPal co-founder Peter Thiel, he already has a lot to be confident about and sports an extremely-young-man-in-a-hurry manner that reminds some of the early Bill Gates.

A strong proponent of nuclear power, he is unfazed by last year’s meltdown at Fukushima that has proven so costly for the Japanese power industry. He points out that the Fukushima disaster resulted from a particularly unlucky concatenation of circumstances. “The Fukushima reactors were forty years old, and built to an early GE design that was one of the worst outside Russia,” he says. “Even so, these reactors actually withstood one of the biggest earthquakes in history. What caused the disaster was the tsunami which shut down their back-up power system. I am not a fan of old reactors but new ones can be built that have no meltdown risk.”

Wilson is betting that so-called fracking, the supposed wonder technology that is being touted as a  new lease on life for fossil fuels, will have  burnt itself out by the 2030s. Thereafter we are back to square one and that, in Wilson’s terms, means nuclear. He thinks that in the long run – say, after 2050 – new nuclear fusion technologies currently in the early stages of development will transform the world energy industry. In the meantime he is touting a  genre known as small modular fission reactors. So small that they can be built in factories rather than on-site, they will be dispatched by train or even truck to their final destination. Wilson is developing a new version that will not need refueling – an advantage that will help minimize safety risks. They will be installed underground and will run for about 20 years before being shut down and sealed up. He is seeking about $20 million in venture capital to push the idea forward.

In the meantime the possibilities of small modular reactors have not gone unnoticed elsewhere. Among major corporations developing similar concepts are not least Tokyo-based Toshiba (in partnership the Westinghouse nuclear business which it now owns), Babcock & Wilcox, General Electric, and Fluor Corporation’s NuScale subsidiary.

Heck when I was growing my High School library touted that anti-nuclear propaganda book We Almost Lost Detroit as being fair and accurate. For the most part things are not that bad any longer, the internet has made I easy for people to learn stuff the schools never told us in the pre computer era.

Just ask yourself this one question anti nuclear activists, how much worse would global warming be today if the USA had not been getting 20% of its electricity from nuclear fission for the last 30+ years? For almost all of that time col would have been the fuel of choice. Would we have 444 ppm of CO2 today if not for nuclear? Or maybe even higher?

Think about that the next time a global warming advocate gets up in your face about the horror of nuclear power.

Startup company Transatomic Power has a new Thorium reactor design they want to build for real world testing.

Cofounders Leslie Dewan and Mark Massie began dreaming up the idea in 2010, while working on their Ph.D.s in nuclear engineering at MIT. “We realized this is probably the smartest we will ever be in our lives,” Dewan remembers. So the two decided to use their knowledge to design a better reactor, one that deals with what they see as the nuclear industry’s biggest problems: waste and safety.

The design they came up with is a variant on the molten salt reactors first demonstrated in the 1950s. This type of reactor uses fuel dissolved in a liquid salt at a temperature of around 650 °C instead of the solid fuel rods found in today’s conventional reactors. Improving on the 1950s design, Dewan and Massie’s reactor could run on spent nuclear fuel, thus reducing the industry’s nuclear waste problem. What’s more, Dewan says, their reactor would be “walk-away safe,” a key selling point in a post-Fukushima world. “If you don’t have electric power, or if you don’t have any operators on site, the reactor will just coast to a stop, and the salt will freeze solid in the course of a few hours,” she says.

Chinese going for broke on thorium nuclear power, and good luck to them

The nuclear race is on. China is upping the ante dramatically on thorium nuclear energy. Scientists in Shanghai have been told to accelerate plans (sorry for the pun) to build the first fully-functioning thorium reactor within ten years, instead of 25 years as originally planned.
“This is definitely a race. China faces fierce competition from overseas and to get there first will not be an easy task”,” says Professor Li Zhong, a leader of the programme. He said researchers are working under “warlike” pressure to deliver.
Good for them. They may do the world a big favour. They may even help to close the era of fossil fuel hegemony, and with it close the rentier petro-gas regimes that have such trouble adapting to rational modern behaviour. The West risks being left behind, still relying on the old uranium reactor technology that was originally designed for US submarines in the 1950s.
The excellent South China Morning Post trumpeted the story this morning on the front page of its website.
As readers know, I have long been a fan of thorium (so is my DT economics colleague Szu Chan). It promises to be safer, cleaner, and ultimately cheaper than uranium. It is much harder to use in nuclear weapons, and therefore limits the proliferation risk.
There are ample supplies of the radioactive mineral. It is scattered across Britain. The Americans have buried tonnes of it, a hazardous by-product of rare earth metal mining.

China getting serious about thorium is the possible game changer.
Fast moving,focused, stable, one voice,government with long term agendas and heaps of cash and economies of scale, give it a massive advantage over western democracies.
You just look at their fast rail business it went from nothing to the biggest in a decade.
Thorium could do the same and drive the trains and factories.
Im sure thats the thinking. (along with wind and solar expansions)
Whether the motivation is altruistic measure to improve the lives of its citizens or to maintain stability for the ruling elite,doesnt really matter the end game is the same.

In an effort to reduce the number of coal-fired plants, the Chinese government has brought forward by 15 years the deadline to develop a nuclear power plant using the radioactive element thorium instead of uranium.

A team of researchers in Shanghai has now been told it has 10 instead of 25 years to develop the world's first such plant.

"In the past, the government was interested in nuclear power because of the energy shortage. Now, they are more interested because of smog," Professor Li Zhong, a scientist working on the project, told the Hong Kong-based South China Morning Post.

An advanced research centre was set up in January by the Chinese Academy of Sciences with the aim of developing an industrial reactor using thorium molten salt technology, the newspaper reported. ... og-thorium

A very good, but very long article on Thorium fueled reactors, much more at link below the quote.

Humanity may face an energy crisis as the world's population rapidly grows.

Nuclear power plants can generate bountiful, carbon-free electricity, but their solid fuel is problematic, and aging reactors are being shut down.
A Cold War-era liquid-fueled reactor design could transform thorium — a radioactive waste from mining — into a practically limitless energy source.
US engineers proved such a system works during the 1960s. However, the military canceled the project and it was nearly forgotten.

Companies and governments are now trying to revive and evolve the design, but development costs, engineering challenges, and nuclear-weapons concerns all pose hurdles.

The lifeblood of modern civilization is affordable, free-flowing energy.

It gives us the power to heat our homes. Grow and refrigerate food. Purify water. Manufacture products. Perform organ transplants. Drive a car. Go to work. Or procrastinate from work by reading a story about the future of energy.

Today's cheap, bountiful supplies make it hard to see humanity's looming energy crisis, but it's possibly coming within our lifetimes. Our numbers will grow from 7.36 billion people today to 9 billion in 2040, an increase of 22%. Rapidly developing nations, however, will supercharge global energy consumption at more than twice that rate. ... ftr-2017-2

The First Thorium Salt Reactors in Over 40 Years Were Just Switched on in Europe

It's still early days, but the use to thorium as an alternative to uranium could provide a cleaner, safer fuel source that would be harder to weaponise. With nuclear energy a booming industry in countries such as China and fear of nuclear threats on the rise, returning to this controversial topic could be well worthwhile.

Netherlands-based nuclear power provider, NRG, are taking a gamble. They're conducting experiments that could see a shift from uranium-based nuclear power to thorium.

In the historical battle between using uranium or thorium as a nuclear fuel, uranium provided both sides of the Cold War with a potential source of weapons-grade plutonium.

But the world is changing, and with global warming, anxiety over nuclear accidents, and the promise of more countries going nuclear, thorium is back on the table as a viable energy resource.

"This is a technology with much perspective for large scale energy production. We want to have a head-start once the technology will break through," says NRG researcher Sander de Groot.

Thorium is an element high up on the periodic table. Similar to uranium, its various isotopes are unstable, meaning the atoms decay by spitting out alpha particles – helium atoms without the electrons.
