  • From what I remember of college chemistry, Nitrogen (N) is not the same as Nitrate (NO3-).  Is the nitrogen in fertilizer converted automatically to nitrate?

  • H2 powered cars

    "What, I ask, will happen when we all drive H2 powered cars, fueled by solar electrolysis?   What, is the difference at that point between a person living in a 4 bedroom house in the exurbs and a person living in a 14 story studio in the old urb?"

    One difference is: the exurb person will still be sitting in a traffic jam in their H2 powered car, wearing down the asphalt, wearing down their patience, driving up their stress level, costing the economy in innumerable ways.

    But at least he/she can step out of the car while traffic is at a full stop, and collect some pure H20 from the tailpipe to drink and get refreshed.

  • Built-in Child seats

    Volkswagen sells a minivan in Europe that has built-in child seats as an option. Its called Volkswagen Sharan.  A friend of mine owns one and says its great and very convenient to fold away when not needed.  Of course this seat doesn't work for infants, but it seems like it should be possible to figure out a good solution for that too.On Umbra on car seat recycling posted 1 year, 5 months ago 8 Responses

  • Oil fund investing

    Wondering about that oil money? It goes into a state "pension" fund.  I read on "Future in our hands" that 11% of the investments made with that pension fund money goes to coal, oil and gas companies, while only .1% is invested in companies doing renewables.

    Here's the link (sorry its in Norwegian, so I guess its mostly useless except as a reference - you'll see the numbers though!)
