Being able to charge electronic devices anywhere is a modern-day problem. That said, “Made in China”
external charging devices can solve this problem to some extent. However, these devices are often poor
quality and can be a fire hazard. To address this issue, the author suggests using an electromagnetic (EM)
spread spectrum, which is highly related to harvesting electrical energy from clean, renewable energy
sources, and then transmitted to charge all types of electrical devices. By applying this author’s proposed
probability-random variables assignment — each type of EM wave is associated with a special channel
with a centralized management information system (MIS) controlled in the background. Such design
can avoid EM-wave interference and encourage a delicate (or special) channel for energy transmitting.
Hence, it can solve electrical devices charging problem or one may get the device charged anywhere
and anytime. Furthermore, with a professional electronic circuit design, together with meta-materials
coated on the surface of a set antenna block, 90–100% of harvested renewable-clean energy might be
transmitted. There is an alternative way of charging by using inductive coils; however, there are some
defects in such case. Further advance is the introduction of EM wormhole which can shield human
beings from the influence of magnetic flux outside the tunnel during charging.
