**Title:** 6 Underutilized/Useless Mega Projects Around the World
**Summary:**
A video presentation highlights six massive projects that have become white elephants due to underutilization or poor planning. The projects include:
1. **Naypyidaw, Myanmar**: A vast, largely empty capital city built in 2005, with a massive underutilized infrastructure.
2. **Brasil Beach Home Resort Pool, Brazil**: A luxurious, often empty pool that locals suggest could be more profitable as a public water park.
3. **Ciudad Real International Airport, Spain**: A large airport that went bankrupt in 2012 due to low air traffic, now mostly abandoned.
4. **Ryugyong Hotel, North Korea**: A 330m hotel project started in 1987, still unfinished after 34 years, serving only as a landmark.
5. **2014 World Cup Stadiums, Brazil**: Several stadiums built for the World Cup, now incurring significant maintenance costs and underutilization.
6. **Burj Khalifa, Dubai**: While the world's tallest building, 20 of its 37 corporate floors are empty due to high rental prices, and it lacks a sewage system, relying on daily waste truck removals.
