After years of false starts,
with the first commercial sales possible within months, a new industry selling motor fuel made from waste is getting a big push in the United States.
Many companies have announced plans to build plants that would take in material like wood chips, garbage or crop waste and turn out motor fuels. For decades scientists have known it was possible to convert waste to fuel. But success is far from assured. Some of the latest announcements come from small companies whose dreams may be bigger than their bank accounts.They are counting on billions in government funds. Big technological problems remain, and even if they can be solved, no one is sure what unintended consequences will emerge or what it will really cost to produce this type of fuel.
Virtually any material containing hydrogen, carbon and oxygen could potentially be turned into motor fuel.That includes plastics, construction debris (废渣), forest and lawn trimming (修剪下来的废料), wood chips, wheat straw and many other types of agricultural waste.The potential fuels include ethanol(乙醇), which can be blended with gasoline, or other liquids that could displace gasoline entirely. Much of the new money flowing into the fields is coming from Silicon Valley, where the venture capitalists who gave the world the Internet revolution see an opportunity to do something similar with the fuel supply. What has been done is small in the scheme of American fuel demand, but it may set the stage for important growth if those first projects prove that the economics can work.
According to the author, even if technological problems are solved, ______.
选项
A、serious consequences will emerge
B、waste can not be turned to fuel
C、success can not be assured
