π‘ Airships have been considered a bad idea due to their flammability and slow speed.
π’ Air transport is expensive but fast, while ship transport is slower but cheaper.
π Trucks are the preferred method of transportation within the US due to their combination of speed and affordability.
π Internationally, air and ocean freight are the main options, but there is a potential demand for a faster and cheaper alternative.
π Airships could offer a middle ground between speed and affordability, potentially becoming a new method of transport.
βοΈ Airships can transport cargo faster and cheaper than freighters and planes, while emitting less emissions.
π The lift of an airship is proportional to the volume of the gas it contains, while drag is proportional to the surface area.
π To make airships efficient, they would need to be built as the largest airships in history.
π A proposal to build a 388 meter long rigid airship for the cargo market.
πΌ A fleet of thousands of airships could dominate the ocean freight container market.
π If successful, this venture could generate $650 billion of revenue per year.
π Airships can provide unique and luxurious travel experiences to remote locations with minimal environmental impact.
π£οΈ Airships require little infrastructure compared to trucks, ships, trains, and planes, making them capable of delivering goods and providing help to remote and disaster-stricken areas.
π Airships can transport large and fragile items, such as wind turbine blades, more efficiently and enable access to inaccessible natural resources.
π A French company is developing a 200-meter long cargo airship to transport logs from remote forests.
π¨ Airships have difficulties with stability and control, especially close to the ground and at low speeds.
ποΈββοΈ The issue of weight imbalance when unloading heavy cargo in airships needs to be addressed for practical use.
π Airships rely on a combination of helium and aerodynamic lift.
βοΈ Hybrid airships work well for light payloads, but not for heavy ones over long distances.
ποΈ Building large airships presents challenges due to the size and required hangers.
π¨ The choice between helium and hydrogen as a lifting gas is debated.
β Certification of new airship designs is a necessary step.
Certificating an airship is a lengthy and expensive process, especially for large rigid airships filled with flammable gas.
The weight needed for structural integrity in large airships creates a size limitation.
Currently, companies are developing and building airships for markets with less competition, but the future potential for airships is uncertain.
