The stunned silence that descended on Washington after the
Financial Times recently reported that China had successfully tested a nuclear-capable
hypersonic glider shows how dangerously inept the US policy establishment has
become at preempting China's technological breakthroughs.
Predictions about China overtaking the United States often
use existing technological processes as their yardstick. Yet, they overlook
another increasingly likely scenario that China has successfully applied
entirely new substance materials to these technologies, bringing unprecedented
breakthroughs in performance.
Beijing is currently experimenting with radically different
substances in three key strategic domains -- nuclear weapons,
semiconductors and energy.
Breakthroughs here will break American dominance and
radically alter the power balance between the two superpowers. The US must both
check its blind spots for more incoming "Sputnik moments” from
China and engage in more disruptive research of its own if it is to stay
ahead.
Somewhere in the Gobi desert, the world's first new
thorium-powered nuclear reactor in over half a century is starting up. The
uranium-233 isotope it aims to produce could take China's rapidly expanding
nuclear arsenal to a whole new level.
China is building on Cold War-era research by the Manhattan
Project team at Oak Ridge National Laboratory in Tennessee in the U.S. Though
the U.S. later abandoned uranium-233 in favor of the naturally occurring
uranium-235, declassified documents from 1966 show researchers at the time
judged uranium-233 to have superior functions to other materials, but only if
kept chemically pure.
Thanks to the co-presence of the element protactinium in the
uranium-233 they generate, thorium reactors were believed to be
"proliferation resistant" for many years. Yet, a variety of
reprocessing methods that separate the protactinium isotopes from the rest of
the nuclear fuel have been developed in recent decades, clearing a pathway for
its use as a high-performance weapons-grade material.
Uranium-233 emits stronger radiation than other isotopes,
producing 15% more neutrons per thermal fission than either uranium-235 or
plutonium-239. It also has a lower critical mass, meaning more weapons can be
made from less material.
This could enable Beijing to not just scale up the number of
weapons in its arsenal but potentially increase each missile's destructive
power, and, having the second-largest reserves of thorium in the
world, the surplus of nuclear energy could drive China's conventional
platforms, including nuclear-powered warships and drones.
Advances in silicon chips will reach their physical limits
by 2025, as dictated by Moore's Law. This seems like a bad thing for China,
which still trails semiconductor leaders Taiwan, South Korea and the US by
two wafer generations.
Yet China is gearing up for what its leaders call the post Moore's
Law-era -- the dawn of carbon-based chips. A recent paper published in the
journal Science by Peking University researchers claimed that they had tested
carbon nanotubes up to three times faster and four times more energy-efficient
than silicon chips. Beijing has allocated a high priority to this field of
research. It is now part of the scientific innovation strategy for China's
fourth five year plan.
Revolutionizing chip material could also bust through
China's biggest bottleneck further downstream – chip making itself. Due to US
export sanctions, China lacks the lithography machines to make
cutting-edge chips. Yet, a state-directed 02 Special Project to develop an
integrated domestic lithography machine supply chain is making progress.
If these machines are designed to manufacture carbon-based
chips, such dual innovations could create the technological foundation for a
whole new foundry ecosystem that would all belong to China. Its chipmakers
could leapfrog incumbents and China would dominate the strategic information
and communications technology hardware of the future.
Though currently the world's biggest energy importer, China
is positioned to become the largest energy exporter if it can pull off its
moonshot project to mine Helium-3 on the moon.
Already, over a dozen Chinese institutes are working to
extract Helium-3 from moon rock samples from last year's Chang'e 5 mission. The
isotope holds more energy than Earth-based minerals with just 40 tons capable
of powering the entire US for a whole year. It is estimated there are at least
a million tons of Helium-3 on the moon.
Though, one US company is planning a mining expedition to
the moon in the early 2030s, China is already streaming ahead with a permanent
mega-base on the moon to be built by around the same time. The US Central
Intelligence Agency space analysts warn that breakthrough dominance in this
powerful and carbon clean resource would make China the 21st century's energy
powerhouse.
If China achieves dominance in any of these three domains, it
will likely displace the US as a global hegemon. There are two key ways the US
can work to prevent this.
Firstly, the US intelligence agencies must better track
China's disruptive research, map out potential pathways for leapfrog
maneuvers and take action to preempt and prevent technological
breakthroughs.
Secondly, the US must take advantage of the lead it
currently has and take on unconventional experiments that are yet another step
beyond what China itself is doing.
Voices on Capitol Hill calling for the US government to
utilize its leftover uranium-233 reserves show that some lawmakers are taking
notice. Yet, it is not nearly enough. Drawing on innovations from yesteryear
may buy Washington some time, but if delayed rear-guard actions are all it can
muster to counter Beijing's multipronged leapfrog, the result of this great
power competition is a foregone conclusion.
