Japan's Richest Man Outlines Renewable Energy Plan

itwbennett writes "Speaking at the launch of his Japan Renewable Energy Foundation, Masayoshi Son, founder and CEO of Softbank, outlined a plan to rebuild Japan's energy infrastructure. Son said the country could shift to renewable energy sources for 60 percent of its electricity requirements over the next two decades. He called for a 2 trillion yen (US$26 billion) 'super grid' across the country, and underwater off the coast, that would zip electricity around cheaply and efficiently to meet demand."

    Hey, now while I'm no fan of either stimulus plan I object to the "wealth redistribution" class warfare rhetoric. We can't discuss class unless it is to defend the wealthy!

    To be more serious, the wealthy have been waging a PR driven class war against everybody else for decades; both of Obama's plans give in heavily to the ruling class and still had/have a big uphill battle for the tiny portion that is ok. This current one will not pass for multiple reasons; one of the big ones being that tax loopholes the wealthy use to CHEAT are being closed to help fund tax cuts for the rest who've been picking up the bill for the wealthy --- the wealth HAS been redistributed upwards at increasing amounts for decades; their pay goes up while the rest are lucky to keep up with inflation (and most do not; including myself... I've never had a job that kept up with inflation.)

    Tax derivatives less than 1% and you pretty much fix our budget issues. "Business" which does not benefit the real economy should be taxed like the gambling it is. Instead, we continue to let them expand their addiction to our retirement funds and soon our social security funds.

    Rob a bank and its a despicable crime; rob nations and its just a statistic.
    With enough money anybody can buy all the praise they desire.

    AC under seawater is difficult. DC under seawater is simple. Both AC and DC suffer from resistive losses in the cable, but AC also suffers from reactive losses, which are far higher underwater. You can even do earth return, either a monopolar transmission or an uninsulated (and thus cheaper) return wire. And no, it's not dangerous; it's already used in quite a few places.

    What is being proposed here is a nationwide HVDC grid, which is an especially important thing in Japan where they have basically two separate AC grids operating on different frequencies. This prevented the southwest from sharing power with the northeast after the tsunami, causing the northeast (including Tokyo) to suffer rolling blackouts for a long period of time. DC can allow power sharing between the two grids.

    Basically, it's a proposal to allow power generated in any part of the country to be consumed in any other part, with minimal losses. And seeing as the country is the size of California, the weather in one part of the country can be very different than the weather in another part of the country, so it's a boon to not just stability and efficiency, but renewables capacity as well. Peaking plants and energy storage systems anywhere in the country can likewise support the entire nation.

    I certainly hope Japan leads the way on this. Europe has been moving in this direction at a moderate pace, but the US only at a snail's pace. It needs a big push.

    Honestly what is wrong with a little wealth redistribution?
    I realize it is not popular on slashdot, but if that is what our economy needs so be it. When the rich have all the money they don't spend it. If we give that to the poor, they will spend it right away.

    Ever heard of Chernobyl, which nearly made the whole of Europe inhabitable, required 600,000 "liquidators" to be mobilised to build a cover on top of the reactor (most of which died of severe radiation poisoning less than 20 years later),

    I lived in less than 100km to the North from Chernobyl power plant, and my health is better than one of most people posting here.

    The scale of Chernobyl disaster was massively inflated for political reasons, and to promote the policy of replacing nuclear power plants with less efficient coal-burning ones, that you see now in Europe.

    bankrupted the USSR (it cost hundred of billions of modern dollars),

    It didn't, because government was on both sides of all contracts related to the cleanup. It's not US, where contractor companies gorge on money thrown at them by the government every time there is any excuse for doing so.

    and removed 10 million of acres of land from Belarus and Ukraine?

    Swamp land. The power plant was build in the midst of swamps.
