Questions & Answers

Q: How does resonant energy transfer technology work?

Resonant energy transfer technology utilizes two coils of wire, which when brought close to each other and resonating at the same high frequency, can transfer power magnetically and wirelessly.

Q: Is wireless power transfer safe?

Yes, wireless power transfer is safe. It utilizes a magnetic field, similar to the Earth's magnetic field, and stays within the source and the device. The technology only transfers energy to devices that work at the exact frequency, which is rare in nature. Additionally, there are regulations and guidelines in place to ensure safety.

Q: What are the potential applications of wireless power transfer?

Wireless power transfer has various applications, including mobile electronics, home electronics, industrial uses, electric vehicles, implanted medical devices, credit cards, and robot vacuum cleaners.

Q: Can wireless power transfer be used for larger devices like televisions?

Yes, wireless power transfer can be scaled up to power larger devices like televisions. A commercially available color television set was successfully powered wirelessly during a demonstration of the technology.

Q: How small can wireless power transfer be made?

Wireless power transfer can be made small enough to power small devices like cell phones. A demonstration showed a Google G1 phone and an iPhone being charged wirelessly using coiled electronics integrated into the devices.

Q: How could wireless power transfer benefit consumers?

Wireless power transfer eliminates the need for cords and plugs, making it convenient for charging devices. It can be integrated into various surfaces like floors, ceilings, and desks, enabling seamless and effortless charging.

Q: What are the environmental impacts of wireless power transfer?

Wireless power transfer can reduce the excessive production and waste of disposable batteries. By eliminating the need for wires, it also reduces the reliance on infrastructure and the environmental footprint associated with power transmission.

Summary & Key Takeaways

• Early visionary, Nikola Tesla, experimented with wireless power transfer using the Tesla coil, but his ideas were never fully realized.

• The love for electricity has led to trillions of dollars invested in infrastructure for wired power transmission and the excessive production of disposable batteries.

• A breakthrough in wireless power transfer was made by MIT scientists who developed resonant energy transfer technology, enabling efficient and safe charging of devices over short distances.
