Interesting ideas? I don't know, at least before age 8. I know that because at that age I was drawing designs for flying machines based on something I heard about a supposed link between electric charge and gravity... in other words, either pseudoscience or taken out of context (high-energy physics, maybe?). I realized this when I built an apparatus to test it: a crude Van de Graff generator on a scale. I ran it for a while but despite building up a small charge (it ran on a 9V battery), the weight remained unchanged. I was disappointed. Over time, my ideas have become more practical. Still, I occasionally have urges to create a bipedal robot or a better coffee machine :)
