Quotes from Robert Zubrin

Some conservatives say that whether it's popular or unpopular, imposing strict limits on immigration is the right thing to do, and it must be defended.

Before agriculture was invented, land was not a resource. Before oil drilling and nuclear fission were invented, petroleum and uranium were not resources.

Putin is sometimes described as a revanchist, seeking to recreate the Soviet Union. That is a useful shorthand, but it is not really accurate.

The goods of the world market are available for Cuba to purchase, but all the foreign exchange is monopolized by the regime, which uses it for its own power and pleasure.

Carbon is the stuff of life, and it's the stuff of everything used by human society. All of our materials are made of carbon or of substances, such as steel or glass, which are produced through the utilization of carbon.

Trillions of dollars in out-of-control entitlement spending cannot be remedied by cuts in NASA, or even in the entire discretionary budget, defense included. Rather, the financial bleeding needs to be staunched where the hole is and nowhere else.

Federal lawmakers need to change the rules so that vehicles converted to use new fuels can be put on the road; the only restriction should be that they pass the same standard state tests that all other cars do.

Were the United States to pass a law requiring all cars to be methanol-capable flex-fuel vehicles, or simply repeal EPA regulations that prevent such conversions from being carried out privately, our immense natural-gas capacity could make a dramatic entrance into the liquid-fuel market.

I think that when humans get around to exploring and building cities and towns on Mars, it will be viewed as one of the great times of humanity, a time when people set foot on another world and had the freedom to make their own world.

The EPA could act to open the transportation-fuel market to vigorous competition from natural gas as well as coal, biomass, and trash, by legalizing methanol. This would force oil prices down, expand the economy, and create millions of jobs.

The EPA code needs to set forth a clear, regular, and rational system of penalties for violations of its code, with the amount of the penalty set in proportion to the amount of pollutant released by a given defendant, and no penalties imposed in the absence of any pollutant released.

The space program needs a goal, and the goal should be humans to Mars.
