From Yahoo News:

RIYADH (Reuters) — Saudi Arabia, the world’s biggest oil exporter and a key U.S. ally, said on Wednesday that the kingdom does not see any obstacle to cooperating with Russia on developing a nuclear energy program.

“There is no obstacle to cooperate with Russia on… nuclear energy,” Foreign Minister Prince Saud al-Faisal told a news conference.

Analysts said the plan by Sunni bastion Saudi Arabia is a warning shot to Shi’ite Iran that it could enter the regional arms race and start developing nuclear capability.

Russian President Vladimir Putin said on Monday during a visit to Saudi Arabia that his country would consider helping the kingdom with a possible atomic energy program.

“On nuclear energy, there was a (Russian) contact with the kingdom and the Gulf Cooperation Council,” he said when asked if Saudi Arabia and Russia had made any agreements.

Saudi Arabia and fellow GCC members Qatar, Bahrain, Oman, Kuwait and the United Arab Emirates, said in December they would study embarking on a joint civil atomic program.

The announcement by the GCC, a loose economic and political alliance, raised concern of a regional arms race with analysts saying the Arab bloc wanted to match Iran’s nuclear program.

The question of whether GCC members can develop civil nuclear power without spinning off a nuclear weapons program is a controversial one. Most analysts see nuclear programs as a threat to world peace, because the temptation of developing weapons is so great. As we saw in the recent deal with North Korea, nuclear programs can be used to bribe other countries for free energy. This may actually increase the incentive to start nuclear programs. Russia blames the United States for kicking off a global arms race, but seems to be participating in that arms race by offering nuclear support to GCC nations. A solution that would make everyone happy would be the development of thorium nuclear reactors, which can produce electricity without making the sort of enriched uranium that can be used in a bomb. Thorium reactors are a 50 year old technology, well within the reach of these countries, given Russian assistance.

The New Scientist discusses a recent study that advocates using of an ion beam generator on the moon to allow the use of far smaller rockets to move from the moon to other locations in space. The ion beam generator would need several hundred megawatts of electrical power from either a large solar cell array or nuclear power.

I have discussed the need on my website to make gigawatts of power on the moon and in orbit in order to begin serious development and colonization efforts.

An alternative to ion beams would be magbeam, a plasma based approach for accelerating spaceships

The beam approaches all require large power sources. The fastest way to achieve this would be to build a lightweight nuclear power source on the earth and launch it into a high orbit (a lagrange point) or the moon.

The power could also be used to power mining and industrial machinery on the moon which has uranium and thorium and the raw materials to make more nuclear reactors. Containment and waste issues on the moon would be less of an issue until colonization happened in a big way. The colonization is better place in rotating structures in orbit, so the moon could be a power and material source for primarily orbital colonization.

Large scale structures for solar power and for space stations could be made with mostly existing or near term technology using magnetically inflated cables Using superconducting wire a lightweight structure could be launched that would unpack from an existing rocket and then expand to be 1 kilometers in diameter or more.

The main points are large scale space architecture is possible in the near term. Large power sources are needed and can be built. We can create viable space habitats with large viable populations properly engineering the technology that we have now. This would be superior to the lunar program that NASA has proposed which lacks the scale necessary to establish viable Lifeboat colonies.
