New Theories / Re: Do a Finite Amount of Infinitesimals Sum to a Finite Amount?

Infinitesimals are generally defined using limits. The limit of a finite sum of infinitesimals tends to zero which is finite.

If you go through it you will find out. Electric cars at best use 3kw per mile. A similar ice sized car achieve 50mpgWTF does '3 kw per mile' even mean? A kw isn't even anything anyway. And a kW is a unit of POWER. Yeah, you're really showing your lack of knowledge already. It's kWhs per mile that are usually quoted. kWhs are units of energy.
Oh no Forbes says that electricity is generated using fossil fuels, and increasing electrical cars means you need more fossils fuels?So, you think 99.998% wouldn't be enough? Wow sounds very technical and scientific. I'm sure you have an equation to prove it and everything. Wait you do HAVE an equation? (I don't think he's got one.)I see you choose to hurl abuse rather than answering the matter at hand, assuming you are responding to me. I have Forbes magazine, although I am sure you will find they do not know what they talk of.

And it would break even in a few years at the absolute most.answer is Yes.To produce enough solar panels to generate the electricity for the uks current usage would require somewhere in the region of 1 billion tonnes of co2, for all our usage that figure is at 10 billion .

That bothered me for quite a while, but I think there's a snow plow effect. As the event horizon tries to form in the first place any matter inside gets expelled.Quote from: wolfekeeper...the 'Firewall model' of black holes where all the mass of a black hole is concentrated at the event horizonLet's take the scenario where a neutron star draws more and more material from an orbiting star onto its surface - until it collapses into a black hole perhaps 10miles across.
Within that 5 mile radius of the event horizon, there would already have been a considerable amount of matter while it was still a neutron star. So that can't really still be stuck on the event horizon.
If it were possible to observe the formation of the black hole (eg with a neutrino telescope), the core of the neutron star might be creeping inwards, just a micrometer from the event horizon - but the event horizon would be bounding outwards by yards and miles. So that material would no longer be stuck on the event horizon (from the viewpoint of a distant observer).

Which does raise the question: What, exactly, has the "nuclear deterrent" deterred? The Soviet Union was an ally of the western powers until they acquired nuclear weapons, since when there have been wars all over the world, mostly with little point and no desirable outcome.I know what it didn't deter. It didn't deter Russia from invading Ukraine. There was no deterrent, after Ukraine agreed to give up the nuclear weapons they actually had to Russia, shortly after the USSR fell.
Linda asks: Can the spinning of the Earth be used as a source of electricity, similar to the spinning of wind turbines?The spinning of the Earth itself can't be the source of electricity, since the Earth has to conform with conservation of angular momentum. Unless something left the Earth or joined the Earth or another external body changed speed, or the Earth radically changed shape, no closed cycle can result in the Earth simply slowing down and electricity being generated, as it will always have the same angular momentum.
At this point I'm assuming you're just here to troll all of us.Exponential,I'm afraid money rules, if renewable where economically superior we would have converted to them already.It will in a few years, and the progress is exponential.
