Study Notes
Elisha Otis and the Safety Elevator
- Elisha Otis, inventor of the safety elevator brake, used a daring demonstration at the 1853 New York World's Fair to showcase his invention.
- He stood on a high-placed elevator, positioned an axman above it, and had the rope cut.
- The elevator fell a short distance, and Otis declared: "All safe, ladies and gentlemen. All safe."
- This stunt highlighted a key message: playing it safe is risky / calculated risks are necessary for progress; avoiding risk is the biggest risk.
- The risk-reward ratio is important for calculated risks.
- Otis's demonstration overcame skepticism about safety.
Impact of the Safety Elevator
- In 1854, Otis installed an elevator in a building on Broadway.
- By 1890, there were ten buildings taller than ten stories.
- By 1900, sixty-five buildings were over twenty stories tall.
- By 1908, 538 skyscrapers existed in NYC.
- Higher floors were desirable due to better views and more prominent revenue, leading to taller buildings.
- This demonstrates that innovation allows for more space-intensive development options and higher-profit opportunities.
Elevators Today
- Modern NYC boasts fifty-eight thousand elevators.
- These elevators support over eleven billion trips per year.
- Globally, the equivalent of the world's population rides Otis Elevator Company products every three days.
- This significant impact highlights the profound influence of Otis's invention on urban development and global transportation.
Further Implications
- Cutting the rope symbolizes taking calculated risks.
- It's necessary for envisioning and pursuing future possibilities and dreams.
- It may involve temporary failures or setbacks.
- Taking risks is crucial to realizing God's plans for personal growth.
