This "small technology" Jiang Cheng was preparing to study was not simple at all.

This is because the technology, called "wireless power transmission," is very important for humanity.

Wireless power transmission allows electricity to be transmitted from a power generation device to a receiving device without using wires.

In simpler terms, it means transmitting power without wires, completely eliminating the constraints of cables.

If wireless power transmission is truly realized, it would not only have significant industrial applications but also great potential in the consumer field.

Just the fact that all household appliances could be used without wires would make this technology spread among the public.

Imagine your computer not needing a wire and you can just turn it on where it sits; how convenient would that be?

When this technology is widespread in all household appliances, there would be no such thing as wires in the home.

Simply install a power transmission device at home, and you can use all your household appliances.

In the future, you won't need a single wire at home and the whole environment would be much tidier.

Perhaps with devices that were initially fixed, the advantages of this technology might not be obvious.

But if this technology is applied to mobile devices, its advantages will immediately become apparent.

Originally, mobile devices that are always usable have to be frequently charged due to power issues.

If you want to use mobile devices while charging, you have to be tethered to a charging cable.

During charging, mobile devices can't really be moved, which is a big problem.

When mobile devices are equipped with wireless transmission devices, they can be charged and moved around at the same time.

In the future, people will no longer worry about power issues, and convenience will be improved considerably.

The cellphone is the best example; when a cellphone is charging, if you want to use it, you must drag around a long charging cable, greatly limiting your range of movement.

Even if you want to take the phone to the bathroom, you have to pause charging.

This is not convenient at all and makes usage uncomfortable.

If cellphones have wireless charging, this problem will no longer exist.

Even when charging, you can carry your phone around without worrying about charging issues.

If Jiang Cheng really develops this technology, he could certainly make a fortune from it.

All the appliance manufacturers would approach Jiang Cheng to purchase the licensing rights for this technology.

At that time, Jiang Cheng could simply sit at home and continuously earn money from this technology.

However, these applications in the consumer field are not the main focus for Jiang Cheng in developing this technology.

Jiang Cheng values its application in the aerospace sector the most, as wiring on Mars is quite troublesome.

In the upcoming construction of cities on Mars, many devices will need power supply.

If all these devices rely on cables for power, laying the connection becomes a big issue.

Setting up a power line on Mars is much more difficult than on Earth, with many more considerations.

With wireless power transmission technology, these wiring issues would disappear.

Once wireless power transmission technology is developed, Jiang Cheng won't have to worry about power supply issues for those devices on Mars.

Jiang Cheng just needs to install a receiving device on all equipment and place a large power transmission device at the base to solve all power issues.

It's precisely because of this practical problem that Jiang Cheng plans to develop this technology during his spare time.

As for making money from this technology later, that's merely an incidental benefit.

In fact, wireless power transmission has long been proposed, but it just hasn't been realized yet.

As early as 1889, the concept of wireless power transmission was proposed.

So, this technology is a topic from over a century ago and is nothing new.

However, this technology, proposed over a hundred years ago, remains unsolved.

Wireless power transmission was proposed by the legendary engineer, Nikola Tesla.

Back in 18XX, he proposed the idea of wireless power transmission and conducted experiments, but the experiments ultimately failed.

Rumors suggest Tesla solved the issue of wireless power transmission, but external pressure led him to abandon the plan.

Others say Tesla left behind blueprints for wireless transmission, but they were completely destroyed.

There are too many legends about Tesla, leaving Jin unsure of the truth.

The black technologies proposed by Tesla are numerous, with rumors that many of them surpass their era and even frightened countries.

So, many of Tesla's research results were destroyed, including this wireless power transmission technology.

But Jiang Cheng doesn't concern himself with whether Tesla actually developed this technology at the time.

After all, even if he truly did develop it, it wasn't passed down, and humanity hasn't solved the problem yet.

For Jiang Cheng, this is a brand new technology and a new challenge.

"Lucy, help me find all the papers on wireless power transmission so I can see previous research results," Jiang Cheng said to Lucy standing in the laboratory.

Before researching wireless power transmission himself, Jiang Cheng followed his routine of reviewing prior research data.

He intended to learn from these failures to prepare for his own success.

After reviewing all previous research data, Jiang Cheng understood why those attempts failed.

The biggest challenge of wireless power transmission is the tremendous loss during power transmission.

In fact, the wireless power technology researched by others isn't unusable.

However, the technology wastes too much energy during power transmission.

Many have developed wireless power technology that wastes at least half of the electrical energy before it can be received.

Wireless transmission technology that wastes so much electricity simply can't be put to use, which is why previous research has failed.

The most challenging part of wireless power technology is how to reduce consumption.

If one wants to convert electrical energy into waves and then transmit it, loss is unavoidable.

Whether it's electromagnetic waves or longitudinal waves, propagation through the air naturally causes attenuation.

After the power transmission device sends energy and incurs losses in the air, the received energy naturally suffers a significant loss.

Moreover, electromagnetic wave propagation disperses, meaning an additional portion of energy is lost.

After such consumption, the energy loss in wireless power transmission becomes substantial.
