I never said it was No, some ****wit from LT on R4 this week was trying to claim it was. There is no methane involved. There are no carbon emissions. Only water. You do not have your facts correct. But the Usernet pedants will still insist water is an 'emission' - thus missing the point entirely But others rightly point out that production of Hydrogen (by BOC for instance) is a very "dirty" process, thus hitting the nail on the head. All LT are doing is moving the problem; they are doing nothing for the environment. Two points: 1. Hydrogen production is not necessarily a 'very "dirty" process'. However, at it worst, it is no worse than the production of diesel or petrol. 2. Once produced, there is no secondary pollution as there would be from internal combustion engines. So, pollution is reduced to one source, instead of thousands, where, potentially, better anti-pollution systems can be used. And London's streets and low-level atmosphere are no longer subjected to harmful emissions. So, by any measure, TfL have reduced harmful emissions. -- Steve -----BEGIN GEEK CODE BLOCK----- Version: 3.1 GCM/B$ d++(-) s+:+ a+ C++ UL++ L+ P+ W++ N+++ K w--- O V PS+++ PE- t+ 5++ X- R* tv+ b+++ DI++ G e h---- r+++ z++++ ------END GEEK CODE BLOCK------ |
