Two pages and counting for "bumper-cars" and four and counting for "speed"......?
Not bad for my first two postings eh ?
Anyway....Lets look at some of your latest barbs shall we:
Strewth....where do I start ?
All fossil fuels are made from trees and the clearcutting of trees in modern days exacerbates the problems associated with burning fossil fuels.
When I said "exhausts" I was including the exhaust from our own human factories. We breath in oxygen and breath out CO2 and Nitrogen which the trees and the plants metabolise to keep the cycle going. ( The "balance of nature" ! )
To the one who indicts that I contribute to this unbalance of nature by my consumption of plastics and electronics.....Yes I do - for my sins - but I do not intend to live like a hippy or a hermit just to fulfill my promise to nature. I consume like any other modern human does but I am conscious of the damage that consumption does and I recycle as much of my waste as I possibly can. I do NOT feel guilty as I do whatever is within my power to be as "green" as I can.....
DO YOU ?
"What has this got to do with road-safety" ?
Using a little writers licence I swung the "road-safety" theme around to the safety - or lack of it - when one walks along the road on a morning where the rush-hour traffic is making my life less safe than it should be because of the fumes from all of those fossil-fuel burning vehicles.
That's road-safety too !
"Atmospheric water-vapour"..
While I do NOT contribute to all of the scaremongering about global warming I do listen to as many of the experts as I can in this respect.
As I have already said that most of the surface of the world is covered in water and the skys are full of it and the animals are made from it we should have no reason to fear such an inert substance if it is exhausted in tiny amounts by fuel-cell engines.
Global warming is a very inexact science and like the chaos theory of the weather we are only now just beginning to understand the complexities of the warming and cooling cycles of the earth.
Hydrocarbon exhaust is a different thing ALLTOGETHER !
Hornet....
"Here's a lecture".....Don't be so serious. I was just being humerous ! Try to see more deeply into my writings please.
"Natural warming gasses"....Of course these gasses from volcanoes and methane from cow's backsides and from the natural breakdown of matter MUST be considered, but we cannot worry about these outputs as they ARE natural and as so they contribute to the balance of nature. What we do by our rabid consumption of natural resources is NOT natural as we are very capable of doing stuff that was never intended to be done naturally.
We can also recognise this and do something about it if we really care.
"The laws of thermodynamics"...( what a great word that is "thermodynamics" ! ).
What you are talking about here is really perpetual motion !
I am not suggesting that the breakdown of water into Oxygen and Hydrogen by the electricity generated by the fuel-cell reaction is a perpetual motion flaw. I am only reporting what the carmakers say they can do. YOU find out why they say that as I just believe them. In fact I would be more inclined to accept that a tank of Hydrogen as a fuel would be more efficient in running a fuel-cell engine. ( Taking the oxygen needed from the outside air of course ! ).
Just out of interest....The Arabs with the help of General Motors and BMW are at the moment building plants on the Persian Gulf coast that make cheap Hydrogen by using the sun and photovoltaic cells to do the water split. They will bottle the Hydrogen and Oxygen and flog it along with the sea-salt that comes as a by-product.
Finally....Cats versus lean-burn....
Yep, you are right that even although Cats do work at optimum efficiency, lean-burn engines are in the main better for the environment. No argument here ! ( they are STILL polluters ! ).
Unlike many here I am willing to listen to ANYTHING that will improve the quality of the air that me and my children and my grandchildren breath.
The rest of you fuel-burning petrol-heads can go on and on in your in-bred vroom-vroom existence here and you can plunge your heads into the sand whenever you see something that puzzles you, but remember.....watch out for Greenpeace warriors looking for somewhere to park their bicycles.
