As for Australia and Brazil, it's unavoidable; they have to rely on each other for raw materials.
Manufacturing shortages can be addressed through industrial upgrading, but raw material shortages can only be resolved through interstellar colonization.
After taking over Singapore, Zheng Li established an aviation company in addition to the energy group and artificial intelligence enterprise.
This aviation company specializes in various types of aerospace fuels.
From a fuel perspective, or from an energy perspective, hydrogen energy has always been one of the mainstream directions chosen by Blue Star.
Although only Japan has consistently invested in hydrogen energy.
Other countries are pursuing a two-pronged approach, primarily investing in lithium batteries, but also not abandoning investment in hydrogen fuel cell technology.
Neon is going down a single path to the bitter end, investing a lot of resources in hydrogen fuel cells.
Hydrogen fuel cells, as aerospace energy source, offer higher energy density, lighter weight, greater range, and faster turnaround time.
This undoubtedly sounds like a very promising technological path.
But why has this remained a technology roadmap for corporate R&D instead of being implemented?
Many startups claim they will build aircraft powered by pure hydrogen fuel cells.
Startups like Zeroavia, which plans to build 10 to 20 passenger planes powered by hydrogen fuel cells by 2024, have also received a donation of five million dollars.
In fact, by 2024, there was still no sign of it.
Airbus has even claimed that it will develop the world's first zero-emission commercial aircraft by 2035 using hydrogen fuel cell technology.
By 2039, it was still just a plan; not only had it not been implemented, but no laboratory products had even been seen.
The biggest drawback of hydrogen fuel cells is the risk, as there has always been a lack of effective means of large-scale hydrogen storage.
The biggest advantage of hydrogen is that it can be obtained from the lunar polar regions and delivered to Leo cheaply.
If the lunar water were to enter Leo via an atmospheric braking system from a transfer orbit, 25-30% of the water extracted from the moon could be delivered to Leo for use as propellant.
By pairing this with a ferry that has a reuse life of only 100 times, a propellant price of less than $50/kg can be achieved, which is much cheaper than sending it up from the surface, thus greatly reducing the cost of deep space logistics.
The first product from Singapore's newly established Space Group is a comprehensive solution for hydrogen fuel cells.
This solution and product have already been sold to both NASA and SA.
Meanwhile, the second product is a super fuel with outstanding combustion efficiency and energy efficiency ratio.
As for the second product, NASA and SA are currently working intensively to modify their space engines.
