    Average SF home is over 2,000 sq. ft. Assume a roof size, conservatively, of 1,000 sq. ft.

    Most new housing in SF is not single family -- when I lived in SF, my share of roof for my 1000 sq ft apartment was around 100 sq feet.

    10 inches of rain on 1,000 sq. ft. is around 6,000 gallons available per household per year.

    Even if I could capture 6000 gallons of water, where would I find a place to store a 10 x 10 x 8 foot container that weighs 24 tons?

    You could provide for 12% of residential water needs just by people not sending their roof water to the sewer system.

    Why shift billions of dollars of costs to consumers to build home water capture and treatment systems when cutting just 3% of agricultural usage would free up the same amount of water? You know what's easier than capturing residential roof runoff? Not planting water-heavy crops in the desert and shipping them overseas.

    Imagine if we reused the water that lands on roadways...172,000 miles of highway, average width of ~10 feet...68 billion gallons of water wasted each year...almost what the entire state uses in a year.

    I don't think you understand just how much water california uses -- residential use along is 6 - 8 million acre feet, 68B gallons is only around 200,000 acre feet. It would cost billions to build 172,000 miles of highway water reclamation and treatment plants.

    There are reasons they get connected. Many times the in-flight entertainment systems need to know things like the position, speed, altitude and heading to perform their assigned tasks. You want the entertainment system to be turned off below 10,000 feet AGL, or if you want the system to supply your customers a graphic that gives the position, speed, heading and accurate ETA then you need to get that information from the flight management system. I can imagine that it might be important to change how the data systems connect to the internet based on where the aircraft is (choosing the cheaper data path when it is in range) or use that data connection to report maintenance information to the airline's mechanics.

    There are plenty of reasons the flight controls might not be totally air gapped from the in-flight entertainment systems.

    RS-232 with the the RX wire clipped on the avionics side would be a good way to pass that information in a one-way direction. Or just use a dedicated GPS receiver for the entertainment system.

    A few GB is *nothing* -- just encrypt it and email it to yourself, set up multiple accounts with different email providers if you don't trust that Google will be around for the long haul.

I keep my data in Amazon Glacier -- for $10/month (it's mostly old family home videos converted to digital along with a lot of TIFF photos). If I needed to recover the data all at once, I could send them a hard drive (plus a fee) and they'd restore to that hard drive and mail it back to me.

    Death Valley is next. I'm pretty sure turtles float.

    I don't think you understand the limits of a siphon -- the maximum rise along a siphon for water is 32 feet (the same limit as the limit for a suction pump, which is why well pumps are at the bottom of the well) -- any higher and the pressure within the liquid drops below its vapor pressure and bubbles form, breaking the siphon. It'd take large pumps and a lot of energy to pump the water over any significant rise - even if you extract some of the energy on the way down, you don't get nearly as much back as you put in.

    Since the Salton sea is below sea level, you could tunnel the water in -- though it would take massive pipes/aqueducts for enough water to flow for significant energy generation.

    So we kick them back out again, and start the cycle again. (Saying goodbye to their spending power and wages we just paid them, since they take it back to India [or wherever])

    Even if the employer files for H1-B revocation, it can take months to process that paperwork, so generally if an H1-B holder loses their job they have a bit of time to search for employment - they'll usually be able to transfer their visa to a new employer if they find a new job within 30 days. My company just hired an H1-B applicant that was in this situation -- his employer shut down suddenly, he was jobless for about 2 weeks before we hired him and filed for the transfer.

    No INS agent is going to bang on your door and take you away the day you lose your job.

    While some H1-B's may scrimp and save up money to send home (or take back home with them at the end of their employment), most H1-B's I know spend most of their money just like everyone else - on housing, food, transportation, entertainment, etc. Likewise, if they are only in the country for a few years, they will have paid social security and medicare taxes that they will not get any benefit from (though they may get relief from some or all of their social security tax obligation if they are from a country with a totalization agreement with the USA -- mostly European and (some) Asian countries, notable exceptions are India and China)
