Whats the cheapest altenative fuel?

Question

Whats the cheapest altenative fuel?

Answer 1

Technically you can get used vegetable oil (for biodiesel) for free, if you find a restaurant that will give it to you.  Generally biodiesel costs on the order of $2.50 per gallon, I believe.

Electricity is generally the cheapest alternative fuel.  An electric car will cost about 2 cents per mile to refuel.  In comparison, a gas car that gets 30 mpg with gas at $3/gallon costs 10 cents per mile to refuel.

Answer 2

Stolen heating oil.

Answer 3

wind

Answer 4

Electric  - a few pence a mile, (also £0 road tax & free parking in some cities) even for high perfoemance cars http://www.teslamotors.com (built by Lotus in Norfolk)

and if you have your own home generator/solar panels then free, and you can sell unused "fuel" back to the grid http://www.acpropulsion.com/technology/v...

Electric is even cheaper for bikes than the food requirements of a cyclists pedalling all the way. http://evuk.co.uk/news/index6.html#Low-c...

(and not documented by "top gear" fossil heads who would rather crash a 250mph jet car than mention the 350-400mph bluebird that is looking for sponsorship http://www.speedace.info/bluebird_electr...

Answer 5

You can run cars on human waist and cow waist , it can also be done via chip fat oil, this was well documented on top gear

Answer 6

the oil in alaska,gulf of mexico and the but load of oil shale in Colorado and rocky mountains

Answer 7

I run my Citroen ZX 1.9D on used vegetable oil which my neighbour, who owns an Indian Restaurant, lets me have for free.  So, technically, free used oil is the cheapest and also has the smallest carbon footprint (as it is made from renewable sources).  In my neighbour's restaurant, they change the oil in the deep fryers each week.  They decant the oil into an old container, which I pick up from the back door.  I let the oil stand for a week, to let the water and heavy particles sink to the bottom, then I carefully filter it through old denim then pour it directly into the tank.  I get about 15 litres of "the good stuff" from every 20 litres of used oil given.  If I need more, I buy rapeseed oil from a supermarket at about 72 - 77p per litre depending upon the cuurent price of oil.  Rapeseed, is the cheapest oil and palm oil is useless because it is solid when the ambient temperature is below about 10 degrees C... but I wouldn't use it on moral grounds anyway.

I believe LPG is actually the cheapest commercially available fuel.

Answer 8

normal vegtable oil from tesco or sunflower oil..

Answer 9

anything stolen i suppose but its not really worth nicking fuel! get a diesel car and tell any local hotels or chipshops that you'll dispose of the oil for free. clean the oil and enjoy cheaper motoring! hope this helps.

Answer 10

This depends on where you live as the fuel has to be close! Solar in the warm parts, geothermal almost anywhere, wind and wave where they work out and nuclear almost anywhere. Ethanol is not very cheep to produce unless you add it to a nuclear power plant or solar power plant. Bio fuels have their own costs-cleanup and still have CO2. Solar air may be the best cheapest fuel-but will take some time to workout the distribution.
