It claims that it will run pollution-free on open roads free of congestion. And where are we going to get such roads? Perhaps Toyota also needs to invent technology to colonize outer space :) Ashok Sunny wrote: <blockquote cite="mid442E2BC9.7000908@gmail.com" type="cite"> <pre wrap=""><a class="moz-txt-link-abbreviated" href="http://www.mg.co.za/articlePage.aspx?articleid=268160&area=/breaking_news/breaking_news__business/">www.mg.co.za/articlePage.aspx?articleid=268160&area=/breaking_news/breaking_news__business/</a> This above website leads to a post that Toyota is planning for a future car that has a non polluting engine powered by hydrogen, running on open roads free of congestion. Do innovative technologies like this solve the problems caused by cars? and when is the time that the developing countries foster the new technologies? I feel that the innovative technologies are not going to correct the problems caused by the cars. Yes, they might address the problem of the air pollution but how many new non polluting cars are required to replace the old cars? and what will happen to the old cars? will they be tipped or recycled?. Even though a country manages to buy the new fuel efficient cars, the old inefficient cars usually end up in the third world due to financial reasons..still doing their polluting job but at a different place. In my opinion I feel that, the more a city restricts the use of car and more it encourages public transit or mass transit the easier the environmental and social problems can be addressed. Sunny P.S: It can be found on the link that US is advanced than Japan in the field of Fuel Cells but I wonder how many cars are running on fuel cells. If there is a technology that can convert the existing cars to fuel cells or hydrogen powered then it would be a better choice than buying a new car. ================================================================ SUSTRAN-DISCUSS is a forum devoted to discussion of people-centred, equitable and sustainable transport with a focus on developing countries (the 'Global South').
