#WIRELESS

[maklodes]

You bring a mousegirl over to your place, and she’s super self-conscious about the fact that she’s old-fashioned and needs to be plugged directly into a USB port to function and isn’t modern and wireless, and she’s just so happy and relieved when you tell her that you prefer wired mousegirls and are glad that you don’t have to worry about batteries and keeping track of easy-to-lose dongles and pairing them with their associated mice, etc.

(Not that you’re judging wireless mousegirls – they can’t help how Logitech made ‘em – but you do have preferences.)

(Really, maybe the first person would be more appropriate than the second person here.)

“Right,” begins Draco, heart hammering against his ribcage, “well then–” but Potter’s on him, over him, catching Draco by the nape of his neck as the mattress dips, and now there’s no sentence left to finish, nothing left in Draco’s brain at all. Potter’s possessed by some fresh surety, kneeling up over Draco and reeling him in with a tight fist to the back of his t-shirt, the fabric pulling tight across Draco’s neck, holding him in place as their lips finally meet. The kiss is the same: furious, frenzied, the kind of kiss that’s a claim; the kind of kiss that’s proof.

Reviving Tesla’s Dream: The Future of Wireless Power Transmission

“My project was retarded by the laws of nature. The world was not prepared for it. It was too far ahead of time. But the same laws will prevail in the end and make it a triumphal success.” – Nikola Tesla

In the early days of radio technology, there was a crucial decision point that split wireless technology into two distinct paths. One path, pursued by Marconi and others, focused on electromagnetic wave transmission. The other path, championed by Nikola Tesla, aimed to minimize electromagnetic waves and use the Earth itself for energy transmission. While the world predominantly embraced the former, Tesla’s innovative approach was largely forgotten. Let’s explore Tesla’s lost art.

Tesla's wireless power transmission system, often known as his "Magnifying Transmitter," was a pioneering approach to sending electrical energy over long distances. Unlike today’s wireless technologies, which rely on electromagnetic waves, Tesla's design aimed to transmit energy through the earth, which he believed was more efficient.

Tesla showcased his system’s potential during his 1899 experiments in Colorado Springs. He successfully transmitted energy through the ground, illuminating bulbs about a mile away from the transmitter. Tesla saw this as a matter of engineering: just as a machine that can throw a rock 5 feet can be engineered to throw it 1,000 feet, he believed his system could be adjusted to transmit power across any distance on Earth.

Modern wireless technologies, such as radio, Wi-Fi, and cellular networks, use electromagnetic waves that spread outward from a source. These waves lose strength according to the inverse square law, which means signal strength decreases with the square of the distance from the source. This energy loss is a significant limitation for long-distance communication and power transmission.

Tesla’s vision was quite different. He recognized that while electromagnetic waves were effective for communication, they were inefficient for transmitting large amounts of power. As he put it, “I only used low alternations, and I produced 90 percent in current energy and only 10 percent in electromagnetic waves, which are wasted.” Tesla aimed to minimize electromagnetic radiation, which he considered to be energy-draining. Instead, he focused on transmitting energy through the earth, which he believed was more efficient and recoverable.

Tesla's system utilized a large coil known as the "Magnifying Transmitter," which generated a high-voltage, low-frequency current. This design featured significant self-inductance and minimal capacitance, producing a strong resonant effect. By accumulating and directing massive amounts of energy with minimal losses, Tesla aimed for efficient power transmission. As he explained, “I accumulate in that circuit a tremendous energy... I prefer to reduce those waves in quantity and pass a current into the earth, because electromagnetic wave energy is not recoverable while the earth current is entirely recoverable, being the energy stored in an elastic system.”

The scientific principles of Tesla's system include:

1. Resonant Circuits: Tesla's system used resonant circuits, tuning the primary and secondary coils to the same frequency. This resonance allowed for efficient energy transfer between coils, amplifying energy while minimizing losses.

2. Self-Inductance: A key component of Tesla’s system was self-inductance. A large coil with high self-inductance generated a strong magnetic field essential for creating high-voltage, low-frequency current. Self-inductance helped store energy in the coil’s magnetic field, critical for high power levels.

3. Capacitance: Tesla’s design involved large capacitors to store electrical energy. Capacitance was kept small compared to self-inductance to achieve desired resonant effects. The capacitors would discharge rapidly, creating high-voltage pulses for transmission through the earth.

To construct a system similar to Tesla’s, he advised:

1. Low Frequency, High Voltage Design: Build a large Tesla coil to generate high voltages at low frequencies. Ensure the design minimizes electromagnetic radiation and focuses on efficient energy transfer into the ground.

2. Loose Coupling for Resonance: Use loose coupling between the primary and secondary coils to achieve significant resonant rise. The coils should be inductively linked but not too close to avoid direct energy transfer.

3. Earth Connection: Establish a deep, effective ground connection to allow the transmitter to send electrical currents into the earth, utilizing its natural conductive properties.

4. Minimizing Radiation: Design the system to suppress electromagnetic radiation, aiming to retain energy within the circuit and direct it into the ground. Tune the system to maximize energy storage and transfer.

5. Energy Storage and Discharge: Incorporate large capacitors for storing and rapidly discharging energy to create high-voltage, low-frequency oscillations.

Tesla’s system faced significant challenges, including the need for large, expensive equipment. In 1914, he estimated the cost of his "Magnifying Transmitter" at $450,000—around $15 million today. These financial constraints prevented him from fully realizing his dream and unfortunately led to his public image as a mad scientist with unrealistic future visions. However, the potential applications of his system are vast, from global wireless power transmission to reducing infrastructure costs and powering remote areas. With ongoing advancements in technology, Tesla’s vision may be within reach.

Tesla’s system presents an alternative approach to wireless energy transmission, focusing on efficiency and long-distance power transfer over the broad dispersal of electromagnetic waves. While modern technologies have advanced in different ways, Tesla’s principles—especially his focus on resonant circuits and earth currents—provide valuable insights into alternative methods of energy transmission. Exploring these principles today could lead to innovative applications, such as more efficient long-distance power transmission or new energy transfer methods.

“I'm losing it, Potter. Please stay. Just, five minutes. Two, two minutes—“ “Stop.” Malfoy raised his chin. Pride shone in his pinched face, though his chin wobbled. Ever the little prince on his throne. Harry didn't care. He was numb. In and out. In and out. He unfurled the parchment and ticked the boxes, scribbling something approximating a date and time. In the foyer, he refused to look down the hall at the sound of the fridge door opening. Glasses tinkled as he tied his shoes. The pop of a cork from a bottle had never before sounded lonely, and he was thankful for the gale outside to strip further sounds from reaching him as he shut the door and stepped back out into the storm.

They finish, then, together, and Draco slides off Harry, panting, all the tiredness and sadness coming back in waves; wave after wave after wave. Harry’s kissing his face, his lips, his tears, and they fall asleep like that, half dressed, tangled, dirty, guilty. * * * They don’t talk, but they have sex again in the middle of the night, and one more time in the morning. It’s like a lifelong thirst that will never be satiated. It’s like a crime they must get the most out of, before they receive their sentence.

The Evolution of the Tesla Coil

Nikola Tesla invented the Tesla coil as part of his exploration into lighting, wireless power transmission, and radiofrequency experiments. He developed the coil to produce high-voltage, low current, high-frequency electricity. The Tesla coil consists of primary and secondary coils that are inductively coupled, and the circuit is designed to resonate at a specific frequency. This resonance enhances the efficiency of energy transfer between the coils, enabling the generation of high-voltage, high-frequency alternating current.

His first Tesla coil was a bipolar coil created around 1891, and was demonstrated before scientific institutes from 1891-1893. His patents reveal that they were essentially intended for light production using both high frequency and high voltage at the same time. He also mentions in his patents how he discovered that a single wire could be used to light a light bulb. Generally, light bulbs require two wires to operate – one for the positive (live or hot) and one for the negative (neutral). He also discarded wires completely lighting bulbs wirelessly. Tesla improved upon the bipolar coil over many years using them for gas engine ignition, wireless, ozone production, and to create undamped waves.

In 1893, Tesla developed the bifilar spiral coil, which is a type of coil wound with two parallel wires, known as bifilar winding. The wires are wound side by side in a spiral pattern, maintaining close proximity throughout the coil. It was built in an attempt to avoid the employment of condensers, which are expensive and difficult to maintain. The coils themselves were meant to accomplish the same ultimate object as the condensers.

In 1894, Tesla evolved his coil into a conical coil. A conical coil refers to a coil or winding in the shape of a cone. These coils were sometimes employed in his wireless power transmission experiments and other electrical investigations. The shape of the coil can influence its inductance, capacitance, and resonance properties, impacting its performance in different applications. This coil allowed Tesla to reach tensions of 1 million volts.

In 1897, Tesla developed the flat spiral coil, similar to his bifilar coil. This type of coil forms a flat, spiral pattern. The specific shape and dimensions of the coil can influence its inductance and other electrical properties. The main reason Tesla started using flat spiral coils was because they were relatively safe, since the highest potential terminal is at the center, and also because they better suppressed the sparks, which were essentially losses in the circuit, allowing him to achieve higher voltages:

Another version of his coils was his Helical coil. A helical coil is a coil wound in the shape of a helix or spiral. The helical coil configuration is characterized by the wires being wound around a cylindrical form in a continuous spiral pattern. Tesla utilized helical coils throughout the late 1890s and in his Colorado Springs Experiments. The coils were used in his wireless transmission experiments, and he employed helical resonators to investigate the behavior of electromagnetic waves. The helical shape offers specific electrical properties and can influence the resonance and performance of the coil in certain applications.

Finally, the Tesla coil would eventually evolve into his Magnifying Transmitter. Tesla designed it as part of his wireless power transmission experiments. The magnifying transmitter was intended to efficiently transmit electrical energy over long distances without the need for wires. The system involved a large coil, often called the magnifying transmitter coil, which could produce high-frequency, high-voltage electrical currents. Tesla believed that this technology could revolutionize global communication and provide a means for delivering electrical power wirelessly by using the earth itself as a conductor.

The magnifying transmitter would become his Wardenclyffe Tower. Unfortunately, Tesla ended up lacking the investments and funds to finish his work in its entirety. Some say he failed because his idea didn’t work, but that’s not true at all because his Colorado experiments proved that they did. In his head, the transmission of energy was a matter of engineering. If he had a machine that could send energy 20 miles, then he could build a machine that could send energy a thousand miles. As long as he understands the motive power, he could build a machine that will do all that he requires of it. He simply underestimated the cost of his system. His failures to finish his work would leave him with the public persona as being the mad scientist who had unrealistic ideas for the future.

Ultimately, Tesla would not realize his dream of providing humankind with cheap, unlimited energy in his lifetime; however, his legacy forever lives on through the incredibly impactful experiments, and the evolution of the Tesla Coil.

“Technical invention is akin to architecture and the experts must in time come to the same conclusions I have reached long ago. Sooner or later my power system will have to be adopted in its entirety and so far as I am concerned it is as good as done. If I were ever assailed by doubt of ultimate success I would dismiss it by remembering the words of that great philosopher, Lord Kelvin, who after witnessing some of my experiments said to me with tears in his eyes: ‘I am sure you will do it.’”--Nikola Tesla
