I agree - it won't be electric
The reality is that there are millions of vehicles operating today that use the internal combustion engine. Your average automobile owner looks for a long-term purchase when they buy a vehicle. Most people will not want or be able to afford an electric vehicle in the distant future - 20+ years.
What the automakers can do for all of us to get the current internal combustion engines, gasoline/diesel, to operate on another fuel. I think the best option is developing a system to convert these engines to operate on hydrogen. I do believe a challenge to American engineering and ingenuity will successfully develop a conversion system - water to hydrogen - pressurize the hydrogen gas and use it as the sole fuel or an additive to gas/diesel. I've seen the Youtube videos and I don't believe them. I'll be happy to believe it when I see it - in person. They all say the same thing - we're not in it for the money. Really? Then publish everything. Enough said.
Modern engines can produce huge amounts of voltage and, I believe, could generate the hydrogen gas needed to operate or assist fossil fuels in the operation of the engine. Whether you know it or not, the spark of the spark plug is not 12-volts it is in the thousands of volts due to the collapsing field in the coil during engine operation.
I'll be happy when I can purchase a new Dodge Ram 2500 with a diesel fuel tank on one side and a water tank, for hydrogen conversion, on the other.
America can do this. JFK - the President challenged America to land a man on the moon and successfully return him to earth within 10-years. All we need is leadership on any level - public or private - to do the same thing.
