Answer to Question 1
We would start by building arrays of solar-trough or photovoltaic generating facilities in the deserts of the southwestern United States, where land is cheap and sunlight plentiful. The electrical power produced by these methods would then be used to produce hydrogen gas by electrolysis. The most efficient way to move the hydrogen is through underground pipelines; hundreds of miles of such pipelines already exist where hydrogen is transported for use in chemical industries.
An alternative to burning hydrogen in conventional internal combustion engines uses hydrogen in fuel cells to produce electricity and power the vehicle with an electric motor. Fuel cells are devices in which hydrogen or some other fuel is chemically recombined with oxygen in a manner that produces an electrical potential rather than initiating burning.
Answer to Question 2
Stakeholders are people who have an interest in or may be impacted by a given approach to environmental management, including government decision makers. Both individuals who have a stake or interest in an environmental decision and those who will be impacted by the decision must be involved in making decisions about ecosystem management because both parties will be affected, either economically, physically, or both.
