Calculated guess: likely time and cost to build the Light of Hope:
The Light of Hope would not simply be a large public artwork. It would be one of the most difficult civic, legal, environmental, engineering, artistic, and political projects ever attempted in the United States. For an ordinary person, the scale would be almost impossible to comprehend: a monument the approximate height and presence of the Statue of Liberty and her base, placed on Alcatraz, clad in billions of memorial tiles, surrounded by approximately 800 animal delegates, and designed to become the brightest symbolic light on the planet for an Extinction Education Foundation.
- An act of Congress would likely be required to allow a nonprofit organization to build monumental statues and permanent educational infrastructure on Alcatraz, a federally protected National Historic Site.
- The National Park Service, historic preservation authorities, environmental agencies, local governments, Indigenous representatives, and the public would all have to be consulted before approval could even be considered.
- Every existing historic building, wall, ruin, pathway, cellhouse feature, lighthouse element, dock, and cultural artifact would have to be preserved, protected, and interpreted rather than erased.
- The new statues, plazas, lights, tile fields, pathways, viewing areas, utilities, and educational features would have to be built around the existing prison structures and placed only in open spaces where preservation rules allowed construction.
- The project would need to prove that a new wonder could rise from the island without turning Alcatraz into an amusement park or disrespecting its painful history as a place of imprisonment, occupation, protest, punishment, and memory.
- The central figure and light system would be comparable in scale to the Statue of Liberty and her pedestal, demanding extraordinary seismic engineering, wind-load analysis, marine foundations, corrosion protection, structural steel, bronze casting, tile attachment, and long-term safety planning.
- The proposed vertical beam would need to be designed as the brightest symbolic light on the planet while still meeting aviation, wildlife, migratory bird, marine life, energy, visibility, and city-light regulations.
- Billions of memorial and fundraising tiles would need to be designed, fabricated, cataloged, transported, installed, repaired, and protected from salt air, fog, earthquakes, vandalism, weather, and time.
- Hundreds of four-times-life-size animal statues would require artists, zoological advisors, cultural advisors, structural engineers, foundries, ceramicists, conservation specialists, crane crews, barges, scaffold cities, and years of precision craftsmanship.
- San Francisco Bay logistics would make everything harder: every worker, tile, steel member, tool, scaffold, statue component, light fixture, safety system, and visitor improvement would have to move by water.
- The project would require billions of dollars in construction work and craftsmanship, creating enormous economic activity for San Francisco through skilled labor, fabrication, ferries, hotels, restaurants, waterfront services, tourism, education, and long-term operations.
- It would also require a permanent maintenance endowment, so the island did not become a decaying spectacle, but remained a living extinction education center, memorial, and global gathering place for generations.
