the world needs it

the problem is not to build a eletric car, it's the way we get the electricity.... there's 1 billion cars today, and if we had just 100 mi(10%) of eletric cars... there would be not enough energy. i live near a hidroeletric system and my month's bill it's 100 US$... (I don't have even a airconditioner....) such a shame.

@RealSlimEmre -- forgot to mention that "a lot lower" means around 20% more or less --

@mesothorium but I've also got to add that hydrogen can be produced using biomass and it's produced now (in addition to using electricity) using natural gas, but still internal combustion engines are no where near the limit that I just mentioned so it could be a lot lower than that 87%, refer to this site if you like hydrogen so much it'll make you like it even more but I'm still pro electric almc.army.mil/alog/issues/MayJ­un00/MS492.htm

@mesothorium for any heat engine the maximum efficiency is: 1- (Tc/Th) where Tc is the low temperature sink -- room temperature assume it's 27 degrees C which makes it 300 degrees kelvin -- and Th is the high temperature sink -- that is for internal combustion engine the temperature of combustion -- and for hydrogen the highest combustion Temp. is near 2300 degrees kelvin so the efficieny is 1- 300/2300 = 87 % so it's better to use electric (efficiency of more than 90% is not hard)

[mesothorium]

@RealSlimEmre it is indeed produced with the help of elec, as is everything tbh... but if i had a choice between electric cars or hydrogen* it would be hydro without a doubt, that effecienty is even higher compared to elec vs combustion, and is the most abundant element in the universe, thus no shortage , its hard to really make everything not dependant on ele, we have incorporated it in all of our daily life/machines our life actually, still im pro hydro

[RealSlimEmre]

@mesothorium if hydro means hydrogen then I'm sorry to tell you that hydrogen is produced using electricity as well, and nuclear energy is one of the cleanest ways to produce electricity -- if only it wasn't so dangerous in case of an accident -- also it's better to use electric powered vehicles because the overall efficiency of the car along with the power plant that supplies its power is higher than regular internal combustion engines..
