My question exactly. I assume because auto manufacturers are locked into existing manufacturing models, and cannot design up from a clean sheet of paper. A 15-hp diesel generator, plus a massive capacitor, would make a micro electric-drive car faster than a Ferrari. Ultra-light, with 10-hp...

Just speaking as a programmer, when things don't behave as expected, have you tried debugging? Reviewing the values of all variables at each program step? When things are acting strangely, debugging can quickly lead you to the actual problem, it may not be what you think is causing the problem.

I know something that greatly impacts efficiency, is designing the engine to run at a single RPM. The design can be optimized around the speed of the combustion shockwave, which I believe to be around the speed of sound. This is practical for generators, ships, and locomotives using electric...

Thanks Ranger Mike for your detailed explanation based on real-world experience, I learned quite a bit.

What you are talking about is probability. Yes it is possible for 100 coins to flip to all heads, given enough tosses. But generally they will tend toward half heads & half tails, and that's your second law of thermodynamics, that everything tends toward equilibrium. Its the difference between...

CMB is correct in that burning coal reduced solar input by putting reflective coal dust in the atmosphere. But global warming is inevitable as the Earth leaves the last ice age. Geologically speaking, Earth normally doesn't have ice caps except during ice ages, and the global temperature is...

Population isn't a problem. As soon as you talk "population reduction", you run into severe moral & ethical conflicts. As said before, as nations reach 1st world living standards, birth rates fall off to not even replacing population. The answer is christianity-centric societies & government...

Thanks for your time, mfb.

If many quasars are at redshift 10, and another group is at redshift 6, what is the speed of the second group relative to the first? The redshift 10 group can be considered "at rest", so the redshift 6 group is heading in our direction at what rate? For this scenario, let us assume all the...

I was under mistaken impression that majority of quasar light came from accelerated material in magnetic beams, thus i was puzzled by what was powering the magnetic beams.

Thanks Drakkith. On another question I asked, I found out the accretion disks are the major light-emitting component of quasars, so now its fitting together. Thanks for your time.

Thanks again for refining my understanding.

So you say quasar light comes from the accetion disk being consumed? Hm, that news to me. And that explains their great brightness? Wow, that's going to take some digesting...

About metallicity, yes black holes have no hair, meaning we can never determine what constituents went into it. So all metallicity readings are coming from the accretion disk.

Hi Bandersnatch, Great name. Thanks for your answers, and yes I suppose I am talking blazars. I did some reading on related threads below, and found the material jets only move at 1/10 the speed of light, which won't falsify the redshift much. I thought they moved at relativistic speeds, which...
