"Tesla generates a powerful pulse of electricity, and drains it into the
ground. Because the ground is conductive, it doesn't stop. Rather, it
spreads out like a radio wave, traveling at the speed of light, 186,000 miles
per second."
And all this time I thought only light travelled at the speed of light :/
While I read that article, I was thinking, what if we found a way to 1. direct the current through the earth to a specific location reliably and 2. managed to represent bits accurately within that current? Free international communication, without networks of cables ;P
- kirubakaran 19y agoRadio wave is electromagnetic wave (aka 'light' in a range of frequency). But "speed of light" in non-vacuum is lower. "direct the current through the earth to a specific location reliably" Earth is not homogenous. I wonder if pointing a low frequency laser into the ground will accomplish anything. It most likely will be refracted in an unpredictable inconsistent way.
- Hexstream 19y agoWell, what if we transmit known data in a strong signal from one end to the other and then compare what was received to what was sent... (insert big hand waving) if we replicate those steps x times, we might be able to map the "interference structure" of the Earth and compensate for that somehow... This is admittedly almost impossibly complicated.
- kirubakaran 19y agoSure but the insides of the earth keep changing right...
- Hexstream 19y agoWe could recalculate the "interference infrastructure" every couple seconds... Remember that we don't need 100% accuracy also; TCP/IP layers reliability on top of unreliability.
- DaniFong 19y agoAlso, an electromagnetic wave is not current, the bulk of which actually travels many many orders of magnitude slower.
