  1. Re:Price won't come down on Tesla's Household Battery: Costs, Prices, and Tradeoffs · · Score: 1

    So their is enough lithium in the world for everything without going to the ocean and we don't need to mine the ocean. Good to know.

  2. Re:and... on Tesla To Announce Battery-Based Energy Storage For Homes · · Score: 1

    Deny it all you want, but Lithium ion based batteries are reaching the limits of their energy density.

    And energy density is not relevant for grid purposes. Even using 0.9 MJ/L you can still store 150Kwh in 600L

    Space junk: 10g
    ISS: 450,000 kg

    Also to deorbit the space junk you would have to boost the ISS which they do anyway.

    Because the Pacific garbage path and zero G do not share any characteristics that would allow you to share tech between them.

    Pumped storage is the majority form of storage.

    It actually depends on the situation. Reduce emissions by a ton and it does not matter where it is. US or India.

    Setup solar in India and quality of life improves a lot while not having to burn more coal to power it.

    Hot water heat pump is a very good auxiliary load.

  9. Re:regulation? on 3D Printed Guns Might Lead To Law Changes In Australia · · Score: 1

    The amendment says well-regulated. The argument is over what well-regulated means. If you allow anyone to get a gun that is circumventing the amendment as well.

    Only decent large scale storage is pump-storage hydro, or solar thermal with heat storage.

    The official election season does. You still get ads before then but not a lot. (And mostly they are the government saying this new policy of ours is a good idea)

  19. Re:Mandatory doesn't sound all bad to me on Obama: Maybe It's Time For Mandatory Voting In US · · Score: 1

    79 seat swing total in the last two state elections is a big change (total is 89)

    18/76 non major two parties in the senate.

    Without mandatory voting only those who have been convinced to vote will vote - which also generally means the major parties who have the money will be the ones they vote for.

    All 5 of the major datasets (RSS, UAH, HadCRUT4, GISS, NCDC) show no warming for between 14 and almost 18 years. In that time CO2 has risen 8-10%.

    You mean temperatures have not risen since the super el-nino that put a lot of heat from the ocean into the atmosphere?

    What happens if you look at 10 or 20 years?

    By the way lost in the politics of CO2 is the fact that at 150 PPM all plant life above the oceans dies. Followed very shortly after by all the animals.

    So people are wanting to get back down to 280 and somehow this would mean going down to 150?
