Elon Musk, the boss of Tesla, said that using hydrogen for cars is not a good idea. He called it "silly". Many experts also think that using hydrogen vehicles will make it harder for the world to reach zero emissions from cars. Instead, they want cars to use batteries that store energy. Elon Musk's company, Tesla, makes only cars with batteries, not hydrogen cars. Read from source...

Elon Musk Slams Use Of Hydrogen For Cars, Terms It 'Silly' As Toyota Gears To Promote Its Fuel Cell Vehicle Mirai At Paris Olympics

1. Inconsistencies: Elon Musk criticized hydrogen fuel cells for cars but admitted it could be viable for rockets. He seems to lack consistency in his views on hydrogen fuel cells.

2. Biases: Tesla, Musk's company, exclusively manufactures electric vehicles, while Toyota has both electric and hydrogen fuel cell vehicles. Musk's criticism seems to have a conflict of interest due to Tesla's position in the market.

3. Irrational arguments: Elon Musk's assertion that hydrogen fuel cells are "silly" for cars doesn't provide any logical reasoning to support his statement.

4. Emotional behavior: Elon Musk's response to the enthusiast who brought up the open letter appeared to be more emotional than rational. He could have provided a more level-headed response.

In conclusion, Elon Musk's criticism of hydrogen fuel cells for cars lacks consistency, may have conflicts of interest, and relies on irrational arguments and emotional responses.

1. Tesla (TSLA) - BUY: Elon Musk's statement against hydrogen as a fuel source for cars supports Tesla's focus on battery electric vehicles. Tesla is well-positioned to benefit from the increasing demand for EVs, driven by the global shift towards sustainability and the phase-out of fossil fuel vehicles.

2. Toyota (TM) - SELL: The article mentions over 100 scientists, academics, and engineers signed an open letter, stating that Toyota's hydrogen vehicles should not be promoted at the Paris Olympics. This signals potential negative sentiment and a slowdown in Toyota's hydrogen vehicle sales, which could impact the company's financial performance.

3. Hydrogen Fuel Cell Industry - AVOID: Elon Musk's recent comments slamming the use of hydrogen as a fuel source for cars, terming it 'silly', reflect the prevailing negative sentiment around hydrogen fuel cell vehicles. Furthermore, Professor David Cebon's statement highlights that hydrogen fuel cell vehicles require three times more electricity than battery electric vehicles for equivalent duty. This indicates higher energy consumption, thereby increasing the need for renewable electricity generating capacity and causing higher well-to-wheel CO2 emissions. These factors, coupled with the prevalent shift towards sustainable energy sources and the phasing out of fossil fuel vehicles, could result in slow growth or stagnation in the hydrogen fuel cell industry.
