    Depends on the loads you're supplying. If you have to convert back to AC anyway then it's less efficient because you have losses converted AC to DC at the power station and then again converting from DC to AC at the local network. You also needs larger neutral wires.

    Skin effect is negligible at 50-60Hz.

    With DC you also lose your inertia. If the electricity has no frequency, how do you know whether you're generating enough? With AC, the frequency drops when you're not generating enough and rises when you're generating too much.

    Nope, distribution is AC.

    They're only experimenting with DC because more things are starting to run on DC.

    And what about the low, and medium level waste?

    Socks and gloves. That's why we shouldn't have nuclear power. Great.

    Mid and low level wastes form the bulk of radioactive wastes from a plant and share the same dump as radioactive wastes from other industries like medicine, fossil fuels, fertilizer etc. So the costs are shared between various industries. Even if there's no nuclear plant, we will still need dumping grounds for the same kind of wastes that come from other industries. The disposal of such wastes is normal and causes no harm to either people or the environment as long as the packaging is good.

    The only thing to worry about is spent nuclear fuel, nothing else.

    Yes. Every time you enter an active area you need a new set of socks and gloves (one use plastic/rubber), which need to be discarded afterwards.

    Medicine is necessary. Fossils fuels don't have radioactive waste and neither does fertiliser. Waste from fossil fuels (ash) is used in fertiliser and Portland cement as well as gypsum in plasterboard.

    Then you have the reactor materials, the instrumentation and electrical wiring from active areas, the remote handling devices used in waste processing and facility maintenance. It's a really big expensive mess.

    Pretty much everything except nuclear waste is pretty much disposed off the same way.

    For a population like India's, hospital waste alone will be many dozens of times more than mid and low level nuclear waste.

    Over the past few decades, however, a series of studies has called these stereotypes into question. Among the surprising conclusions: the waste produced by coal plants is actually more radioactive than that generated by their nuclear counterparts. In fact, the fly ash emitted by a power plant—a by-product from burning coal for electricity—carries into the surrounding environment 100 times more radiation than a nuclear power plant producing the same amount of energy.

    We should make a catalog of funny claims by bmd.

    Precipitators collect fly ash in any self-respecting fossil fuel plant and it is used in Portland cement and as an aggregate in fertiliser.

    Not when you start supplying everyone with electricity it won't.

    I've already shown you a case study for a large biomass generator where 206mt grows back for the forests used and only 126mt is harvested for the period of 2016.

    The bottom line is that private companies can generate electricity by non-nuclear means but no private company can generate via nuclear because they can't handle the liability afterwards. It's only viable for a public company where the liabilities can be dumped on the taxpayer.

    Why will we supply nuketricity? I was talking about a global tricity grid with solar plants.

    I've already shown you how people are indeed cutting down massive forest to provide wood for the same facilities.

    What you haven't shown is how many trillions of trees we need to cut to produce energy on an exajoule scale.
