Alternate fuel vehicle for The Green Leaf Inn??
I am currently driving a Toyota Highlander, which I love, but it’s a gas hog. It needs to be either converted to alternate fuel or traded in for a more suitable vehicle for some one who owns a net-zero inn. The more I learn about alternate fueled vehicles, the more I understand why hybrid vehicles really are the best eco-aware choice for people right now. The conversion process to electric will be very expensive, if I can even find someone who has converted a Highlander. Ford has a cute little truck called a Transit Connect that can be purchased as an all-electric, but the range – especially while transporting a large payload, is not very good. For example, I could get to Madison from Lake Geneva, but I better be able to recharge somewhere for the trip back – especially if I was hauling stone, or other construction material back for the Inn. Our community is getting there, and we are planning charging stations for all electric vehicles to the Inn, but as a whole, this area isn’t quite there yet.
Now I’m investigating propane power and I will be attending the “Powered by Propane” workshop in Milwaukee this April www.wicleancities.org to learn more about it. When we were in Vegas two years ago for the International Green Building Show, we saw a propane Ford F150. Wow it was exciting – the problem was, I think it was created for the show as a give-away only. The other problem was I didn’t win it. When I ask dealers in our area about this truck, they look at me like I have two heads, so I guess I need to do more research.
So, Propane would be cheaper than gas, pollute less and give the same power as gasolene. But what exactly is it and where does it come from? I went to Wikipedia and found some answers:
Propane is produced as a by-product of two other processes, natural gas processing and petroleum refining. The processing of natural gas involves removal of butane, propane and large amounts of ethane from the raw gas, in order to prevent condensation of these volatiles in natural gas pipelines. Additionally, oil refineries produce some propane as a by-product of cracking petroleum into gasoline or heating oil. OK, so the first source is pretty good. Where do we get this natural gas though? 90% of it comes from production in the United States. Here’s some more facts I learned:
The advantage of propane in cars is its liquid state at a moderate pressure. This allows fast refill times, affordable fuel tank construction, and ranges comparable to (though still less than) gasoline. Meanwhile it is noticeably cleaner (both in handling, and in combustion), results in less engine wear (due to carbon deposits) without diluting engine oil (often extending oil-change intervals), and until recently was a relative bargain in North America. In the United States the propane fueling infrastructure is the most developed of all alternative vehicle fuels. Many converted vehicles have provisions for topping off from “barbecue bottles”. Purpose-built vehicles are often in commercially owned fleets, and have private fueling facilities. Propane is bought and stored in a liquid form (LPG), and thus fuel energy can be stored in a relatively small space.
I will keep researching. My goal is to have an alternative feuled vehicle to show people in time for Ecofair360 2011.]
