As of September 2021, the Tesla Berlin factory is not yet fully operational. Construction of the factory began in 2020, and while some parts of the facility are nearing completion, the factory has not yet started production. Tesla has faced delays in obtaining necessary permits and approvals for the factory, which has pushed back the timeline for when it will be up and running. However, Tesla has stated that it aims to start production at the Berlin factory in late 2021 or early 2022. **

Some gasoline engines, specifically those with a high compression ratio, could continue running without ignition due to auto-ignition. This phenomenon occurs when the air-fuel mixture ignites spontaneously due to the high temperature and pressure inside the combustion chamber. Engines with a high compression ratio, such as those found in performance or racing vehicles, are more likely to experience auto-ignition. However, auto-ignition can also lead to engine knocking and other damaging effects if not properly controlled. **

Yes, Tesla employees do have the opportunity to purchase or lease a Tesla vehicle at a discounted price as part of their employee benefits.

Nikola Tesla was a Serbian-American inventor, electrical engineer, mechanical engineer, and futurist best known for his contributions to the development of the modern alternating current (AC) electrical system. He is also known for his numerous inventions and patents, including the Tesla coil and the induction motor. Tesla's work laid the foundation for many modern technologies, and his ideas and innovations continue to have a profound impact on the world today. **

A Tesla coil is an electrical resonant transformer circuit invented by Nikola Tesla around 1891. It is used to produce high-voltage, low-current, high frequency alternating-current electricity. The primary components of a Tesla coil include a primary coil, a secondary coil, and a capacitor. When the Tesla coil is activated, it generates spectacular electrical discharges in the form of lightning-like bolts and is often used for entertainment or educational purposes. **

The inventor of the Tesla car is Elon Musk, who is the CEO of Tesla, Inc. and has been a driving force behind the development of electric vehicles. Musk has been instrumental in revolutionizing the automotive industry with the production of high-performance electric cars that have gained widespread popularity. His vision for sustainable transportation has led to the success of Tesla as a leading manufacturer of electric vehicles. **

As a company, Tesla can choose to discontinue its operations or products, but it cannot literally say goodbye as it is an inanimate entity. However, Tesla can announce its departure from a certain market, product line, or business strategy. Ultimately, the decision to say goodbye lies with the company's leadership and stakeholders. **
