AC and DC power lines both loose energy to resistance. AC power looses energy in another fashion due to capacitance and inductance called reactive power. By using superconductors (0 ohm resistance) for the power lines, you eliminate all losses for DC, most losses for AC, and introduce new losses for the cooling equipment. Of course, with superconductors the formula isn't as simple as V=IR because then you could get infinite current. (V/0 = I) With superconductors, there is a maximum current density (Amps per m^2 as the area of the cross section of the wire) before the wire starts to produce resistance.

Its claiming a million gallons a day gushing, but at 4 barrels per second, you don't get to a million in one day. You don't even get to the 500k that BP would be so happy about, you get 345.6k/day.

barrels != gallons
1 oil barrel = 42 gallons

so 345.6k barrels/day = 14.5152k gallons/day


This doesn't refute anything else you've stated.

The bill proposes making sure there are an equal number of toilets in Women's restroom as there are toilets + urinals in Men's restroom. They are advocating spending more money and allocating more floorspace for Women's restrooms in comparison to Men's restrooms. They want to favor Women over Men, or they could just get rid of urinals.

FUD, pure FUD. The Athlon FX-57 came out at an initial price of $1031 for distributors. While the intel competitor at the time, Pentium 4 Extreme Edition 3.73 came out at $999. Then the Athlon FX-62 came out at $1031 as well, then a month later the first core 2 duo came out for $999, and AMD hasn't been able to successfully charge a thousand dollars for a desktop processor since. So, saying AMD was never more expensive is flat out wrong.
