Problem: Given the question: Extract the answer to the question from the following context. Question: What is unique about the solar balloon that assists the sunlight to heat up the air inside? Context: A solar balloon is a black balloon that is filled with ordinary air. As sunlight shines on the balloon, the air inside is heated and expands causing an upward buoyancy force, much like an artificially heated hot air balloon. Some solar balloons are large enough for human flight, but usage is generally limited to the toy market as the surface-area to payload-weight ratio is relatively high.

The former California governor would face a constitutional hurdle; Article II, Section I, Clause V nominally prevents individuals who are not natural-born citizens of the United States from assuming the office. He has reportedly been lobbying legislators about a possible constitutional change, or filing a legal challenge to the provision. Columbia University law professor Michael Dorf observed that Schwarzenegger's possible lawsuit could ultimately win him the right to run for the office, noting, "The law is very clear, but it's not 100 percent clear that the courts would enforce that law rather than leave it to the political process."
