First of all I'm thankful very much to Ilon Musk, as he delivers an example of very extraordinary person which take an extraordinary efforts. I track his videos on youtube and consider them as very inspirable. But also I got some questions which are very unclear to me. One of these questions is about the mission of Tesla Motors.
Ilon Mask often says the worthful thought: if you want to understand something, you have to find the most fundamental truth about the subject.
Let's talk about the most fundamental subject of Tesla Motors: electricity as a power for vehicles.
Once Ilon said, if you are trapped in a stuffy room, then you have to go out of this room as soon as possible. It was said about fossil fuel. Clearly. Nothing to add.
But is the fossil fuel is the only possible kind of fuel available for internal combustion vehicles? Probably not. There is also alcohol fuel, which is renewable. Why not to take an effort to find out more efficient way of producing alcohol fuel? There are gigatons of biomass rotting every year (including leaves, straw, dung, hay). What if all that biomass can be turned into alcohol, and by solar energy? There are another issue about combustion engines - greenhouse gas. But rotting biomass emits greenhouse gas in either way, where or not we transform it into alcohol.
Ilon said that electric power allows to utilize free sun energy. That is true. But what about batteries? Even if we drop battery prices 10 times, they will still to be consumables. They need to be produced, continuously, as long as people will drive electric cars. And they also need to be recycled. So instead of dependency on fossil fuel we gain dependency on batteries. Is it sustainable solution? I don't think so.
There are already built a millions of combustion engines and a lot of factories which can produce a lot more if needed. These engines can be reliable enough if properly served. You can see the videos from repair man who shows old LADA 2106 engine after 300,000 km run. It is weared, but it can be repaired and then it can run another 300,000 km. It costs less than $1000/pcs in new condition. It is already available even for poorest people of the world.
So why not to take an effort to save and prolong the goods that are already made and already available almost for everybody?
I hope Ilon will publicly get comprehensive answer to this question. If he already did, I will be appreciate if you link me his answer.
