R. James Woolsey, former Director of the CIA,speaks about oil dependancy part 3 of 3

Ethanol will not work you cant produce enough to replace oil, and you are by enlarge fuelling a car on what you would eat. Stupid idea.

The answer is urbanisation, elctric trains, and BICYCLE, hybrids. Eg pedal assist bicycle / light vehicles, NOT CARS.

@KrunchyJD All good ideas. But there will be some motorized vehicles needed too and can't hurt to look at non-petroleum fuels. Of course, we don't want these coming from food sources or using more energy to produce than they save.

[KrunchyJD]

@mrpitv I believe that efficient motorised vehicles are part of the solution, when mixed into a travel efficent designed city. In saying this I am not suggesting we have ambulaces and emergency vehicles being bicycles.

The problem is that cars are extremely inefficient with only about 20% of the energy used bt the car moving the wheels. Combine this with the fact that most cars are extremely heavy, and most of the vehicles energy is used to move he vehicle not its occupant. Sounds stupid.

@KrunchyJD yet without petroleum how will planes fly or ship's ship goods?

[KrunchyJD]

@TeoTanek I understand that, however, we currently waste far too much petroleum, on people who want to drive around in a city in huge cars. The point of what I am saying is being energy efficient, and using less will allow that oil to go further. Cars are one of the least energy efficient mode of transport, so logically should be used a whole lot less. Private car transport is one of the biggest users of oil.

[TeoTanek]

@KrunchyJD Yeah, I was just pointing out that not always fuels will be replaced with lithium batteries. I think the same about ethanol, Brazil and my country Argentina, are something like the 2 and 3-4th world biofuel producers,so I know about this selfish economic approach in which we use our land to produce energy, without taking in account how much that will impact worldwide in food prices, besides nobody takes in account how much oil we use to produce those biofuels.

Why'd you run from the UFO problem Woolsey?

Get threatened?
