This is essentially correct:
        If they take away net metering they should give wholesale peak prices. This can be more than $10 per KWh.http://eex.gov.au/energy-management/energy-procurement/energy-pricing/the-wholesale-price-of-energy/

If they don't give this wholesale price to homeowners, then the dropping price of PV will mean that large companies will set up large installations, selling into the wholesale spot market at peak prices. Same effect: drop in profits for electricity generators, and an increase in the price of stanby power at night or on cloudy days.

Two words:
1) somatic mutations: http://www.nature.com/scitable/topicpage/somatic-mosaicism-and-chromosomal-disorders-867

2) mosiacs: http://www.forteantimes.com/strangedays/science/2368/chimeras_and_mosaics.html

Mutations happen all through the life of an organism. If that mutation happens in a germ cell (sperm or egg) the mutation is passed down to every cell in the next generation. However, if the mutation occurs in a somatic cell (non-germ cell), then when this cell divides (during growth) all the resulting cells carry the mutation.

There are wireless proximity alarms (designed for keychains or children) that work with your smart fone, setting off an alarm on your phone when the distance goes beyond about 10 meters:

Also look for Loc8tor plus: the range is supposed to be 100 meters.

They are already working on creating Pleistocene park using animals similar to the extinct mega-fauna herbivores.
(http://www.stanfordalumni.org/news/magazine/2008/sepoct/features/siberia.html)

The idea is that mammoths damaged the lichen and mosses of the tundra, thus allowing grass to grow, drying out the soil, preventing the permafrost from forming,

The permafrost locks up nutrients for the plants and animals and forms a high albedo surface that doesn't warm up quickly in springtime.
(http://www.abc.net.au/rn/scienceshow/stories/2011/3101365.htm#transcript)

The scape marks on the bottom of the mammoth tusks indicates that they probably scraped the snow off the grass in winter, allowing other smaller herbivores to find food and survive winter.

The change from tundra to grassland has the potential to have huge climatic effects
  and help prevent a huge release of methane (a much worse greenhouse gas than CO2).

Recreating the Pleistocene grasslands is not a silly, flippant or ill-considered idea
