Totoy.....very fundamental question yan. YES, electricity can be sent wireless but at what power is another matter. For example, radio waves is electricity pero in another form, i.e. electromagnetic waves or simply magnetic energy. You look at a transformer. You have the primary winding and the secondary winding, di ba? Sa isang shell lang sila pero you can separate them. itapat mo primary nakawound sa steel core sa primary na may core din. Separate them by say 1mm or even 3mm apart. You will discover that there still a transfer of electricity to the secondary. MALAPIT nga lang at HUMINA ang current transfer pero it qualifies as wireless transfer of electricity, di ba?
Now, other than magnetism as the medium, what else can we use. WELL, WELL....LIGHT! Point your flashlight to an solar cell.....magkaroon ng electricity transfer, di ba? wireless pa!
kaya, bata pa ako, nag dream na ako to put giant mirrors in the sky-artificial moons. Yun sunlight will become available to the dark side of the planet. Solar panels convert light to electricity.
The elusivbe dream really is to harness the sun's energy NOW. When you burn gas, that was the sun's energy millions of years ago, now released back to the atmosphere. If you burn wood of a 20 year old tree, that was the sun's phosynthesis 20 years ago etc....but if you fry an egg over a hot plate, that is the sun's energy NOW!
