Future Energy Debate Version Of Carnival Of Space #151

Welcome to WeirdSciences and future energy debate version of carnival of space #151. If you have no idea, what a carnival of space is, take a quick guide to it at UniverseToday. As title states this is future energy debate version of carnival of space. So, before starting carnival of space, I would like to introduce future energy debate in few lines. I have reviewed some problems involved with accepting Uranium as a future energy source, which are discussed here. Next Big Future described it as:

1. too much energy to mill lower grades of uranium ore. No net energy for low grades. 100 parts per million.
2. critics point out that uranium is an abundant element; there is plenty of it in the earth’s crust and in seawater. But in both cases the energy needed to extract it would be more than could ever be recovered.
3. there is the argument that we could use uranium more efficiently by developing breeder reactors, which would be 100 times as efficient as today’s thermal reactors. But after 50 years of extremely expensive research, they are still not technically feasible.

Next Big Future presented counter argues:

  • The Rossing mine has a lower Uranium concentration (0.03% vs 0.05% by weight) than Olympic Dam and the discrepancy is even larger in the case of Rossing. Here SLS (Storm Van Leeuwen and Smith) predict Rossing should require 2.6 Giga-Watt-Years of energy for mining and milling. The total consumption of all forms of energy in the country of Namibia is equivalent to 1.5 GigaWatt-Years, much less than the prediction for the mine alone. Furthermore, yearly cost of supplying this energy is over 1 billion dollars, yet the value of the Uranium sold by Rossing was, until recently, less than 100 million dollars per year. Since Rossing reports it’s yearly energy usage to be 0.03 GigaWatt-years, SLS overestimates the energy cost of the Rossing mine by a factor of 80.
  • Japanese plans for Uranium from Seawater would be to place the uranium collection system in the path of ocean currents. Kuroshio current moves 520,000 tons of uranium every year.
  • At a regular meeting of the Atomic Energy Commission (AEC) on June 2, the Japan Atomic Energy Agency (JAEA) and the Central Research Institute of the Electric Power Industry (CRIEPI) reported on technology for collecting uranium from seawater. According to the two organizations, the total amount of uranium contained in seawater – as one of the 77 elements dissolved therein – measures some 4.5 billion tons, about one thousand times more than is known to exist in uranium mines. Even if Japan could collect just 0.2% of the 520,000 tons of uranium transported every year by the Japan (Kuroshio) Current that flows in the Pacific Ocean, it could easily meet its annual need of 8,000 tons.

Your Carnival Of  Space #151 starts from here:

1) The Cold Spot was formed at the last-scattering.

2) The Cold Spot was formed during the photon’s path to us.

3) The Cold Spot is an instrumental artifact.

4) The Cold Spot is a data-reduction artifact.

Full article is here.

This time Carnival Of Space ends up here. Looking Forward to meet you again. I thanks to  Fraser Cain for this week’s carnival of space.  Enjoy FOLKS!!

    Nice article, enjoyed carnival of space 151. I liked Rob’s article fourth spatial dimension. excellent visualization was there. really stunning!

    Hi there, thanks for noting my blog entry, but there’s no link to my blog — just to the starland site and that’s not my blog. My blog is http://www.thespacewriter.com/wp

    thanks much.
