TED-Ed - How much would it cost to buy the Sun? - Cella Wright
Daedalus, the ancient Greek inventor, is initially driven by grief over his son Icarus's death to consider purchasing the Sun from Helios, the Sun God. Rumors suggest he might want to destroy it or harness its power. However, a divine accountant explains the Sun's critical role in Earth's energy systems, including solar, wind, and hydropower, which collectively contribute trillions to the global economy. The Sun's energy is vital for life on Earth, influencing agriculture and the planet's climate. The accountant highlights the Sun's future potential, noting that with proper investments, solar energy could significantly grow by 2050. Daedalus realizes he cannot afford the Sun and acknowledges its value, leading to a reconciliation with Helios, who is relieved to learn the Sun's end is not near. They part with a renewed understanding and hope.
Key Points:
- Daedalus initially wants to buy the Sun, possibly to avenge his son Icarus.
- The Sun's energy is crucial, powering solar, wind, and hydropower industries worth trillions.
- The Sun is essential for Earth's climate and agriculture, supporting a $5 trillion market.
- Future solar energy investments could yield significant growth, with potential for 8,519 gigawatts by 2050.
- Daedalus learns the Sun's value and importance, leading to a change of heart and reconciliation with Helios.

4. š Valuing Solar Assets
- The global solar market was valued between $100 and $300 billion as of 2023, indicating significant growth potential in renewable energy investments.
- Wind energy, which is a derivative of solar influence, was worth between $85 and $150 billion, highlighting its role in the sustainable energy landscape.
- Hydropower, another solar-influenced energy source, was valued at approximately $230 billion, underscoring its established presence in the energy sector.
- The global agriculture market, heavily reliant on solar energy for crop production, reached around $5 trillion in 2022, illustrating the fundamental economic impact of solar energy.
5. š The Sun's Crucial Role on Earth
- The Sun is one of 100 billion stars in the Milky Way and is medium-sized.
- Earth likely formed from the Sunās leftover materials, providing optimal conditions for liquid water and life evolution.
- The Sun contributes to generating Earthās atmosphere, absorbing about 70% of incoming solar radiation, which traps heat.
- Without the Sun, Earth would be untethered, frozen, and inhospitable.
- The Sun's energy drives weather patterns and ocean currents, crucial for climate regulation.
- Photosynthesis, powered by the Sun, is the foundation of the food chain, supporting all life forms.
6. š® Future Prospects of Solar Energy
- The Sun provides enough energy in one hour to meet humanity's energy needs for an entire year.
- Solar panel technology has significantly advanced since the 1970s, improving in efficiency, affordability, and implementation.
- Potential future advancements include the theoretical Dyson sphere, which could capture vast amounts of solar energy directly from the Sun.
- Current technologies such as perovskite solar cells promise higher efficiency rates and lower production costs compared to traditional silicon-based panels.
- Innovative solutions like floating solar farms are being developed to maximize space and energy generation in areas with limited land.
- Challenges such as energy storage and grid integration remain, but advancements in battery technology and smart grids are paving the way for more effective solutions.
