Actually, our last major advance was FETs...

(Field Effect Transistors), which are voltage, rather than current driven. The voltage gain is enormous, enabling other components (resistors, coils, capacitors) to made microscopic. If it not for FETs, microcomputers that drive virtually every form of electronics would be impossible.

Whoever told you about RF "cooking you" is absolutely correct. That is the basis for microwave ovens. Navy air search radars typically have a "kill radius" of 1,000 feet. Birds that fly into the beam cook from the inside and fall from the sky. Sometimes,they explode.

While "gravity" is largely a mystery, it is inseparable from electricity and magnetism. That is why "electrogravitics" are taken seriously at noted learning institutions. Here is a list,which I have not completely vetted http://www.stealthskater.com/Documents/ElectroGravitics_01.pdf
