One of the problems (I think) associated with liquid and electric vehicles is when comparing energy derived at a given weight,
Lead acid battery___1x Ethanol____________50x E85________________80x Gasoline_____________100x I'm unsure of the source of these figures and question how it was derived but I'd assume it may have converted the energy to Btu/lb or J/kg for comparative purposes only BUT technical studies indicate that ethanol and E85 Internal Combustion Engines can be dedicated to provide equal (or slightly better) fuel economy per given volume (e.g. one litre) as unleaded gasoline. Another comparison would be cost per given unit of energy such as a comparable price for electricity to petrol, for example -- One US gallon of Low-Heating-Value petrol (gasoline) = 115,000 BTUs divide by 3412 BTUs/kW = 33.7 kW times $0.07/kW = $2.359 US dollars for the equivalent residential electrical amount of energy per US gallon of unleaded gasoline. Costs per kW may very. Using the BTU figure from -- Energy Conversion Facts http://bioenergy.ornl.gov/papers/misc/energy_conv.html Energy Conversion Calculator http://www.ex.ac.uk/cimt/dictunit/ccenrgy.htm I imagine comparative factors could be used using (Compressed) Natural Gas, LPG, hydrogen, coal, biofuels, wind, hydroelectric, PV, etc. ` Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Biofuels list archives: http://archive.nnytech.net/ Please do NOT send Unsubscribe messages to the list address.
