Natural gas causes less pollution, is much more cheaper than petroleum and saves travel cost by a good margin. However, it is necessary that ample natural gas resource be present if the shift is under consideration.
Agreed, mydesign. Natural gas pollutes less, whih is a big advantage. The downsides are the initial vehicle cost is a little higher, energy density is lower, and natural gas, for some reason, is not very compatible with the new higher-tech, direct injection systems.
Mydesign, You are correct. Many vehicles could be modified to run on natural gas. I have a friend who has traveled extensively in Asia and found lots of natural gas powered vehicles there. There are also lots in South America. My understanding from him is that they have longer range. I am not sure of how that is compared.
As Chuck said, most of thevehicles we will see are trucks. In Chicago a large concrete company has said that all of its trucks are being replaced with natural gas burning vehciles by 2020 (I think). They have already started to deploy. The company is Ozinga and they have over 500 vehicles.
One of the big impacts of using natural gas in large trucks is that they tend to use a lot more fuel than the average automobile. That should have an outsized impact on oil usage here.
I don't know much about LPG, mydesign, but I'll tell you what I know and maybe our readers can add to it. Natural gas is essentially methane, whereas liquefied petroleum (propane and butane) is a hydrocarbon-based gas. It is used in automobiles, but its energy density is lower than that of gasoline, so its fuel consumption is higher. As for a comparsion of emissions -- I'll leave that to any of our smart readers who want to chime in.
Charles, if am not wrong, these natural gases are one of the purest forms of gasoline in gaseous stage. Then I would like to know what's the difference between the LPG (liqudified petroleum Gas – cooking gas) and natural gases.
Charles, there is no doubt that now days more and more vehicles are equipped with natural gas tanks and fuel injection system due to various reasons. I think the major advantage with natural gas is its less pollution level and cost effectiveness.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
