I have a pipe going down into the ground xkm in that pipe there are turbines that can be adjusted to resist the flow of water down the pipe, this resistance heats the water, by the time the water gets to to bottom of the pipe it is boiling, it returns to the surface as steam along another insulated pipe. how far does the water have to fall before it produces enough energy to boil itself?

My cat killed a black snake, approximately 9 inches long, with a large pale stripe behind its head, faint whitish markings that look like inverted "V"s, and a grayish underbelly that appears to resemble the limited collection of pictures of Philippine snakes. That or a tree snake. Really would like direction to a better catalog of snakes here in the PI.

Will man build Lunar Colonies or Lagrange Colonies first?

I feel that a lunar mining establishment is require first for raw materials, including water. We would also need to establish long range mining ships to go to the inner astroid belt to find astroids and tow them back to earth area for us to use to mine metals from. In this way we could, build the monolith stations at Lagrane points. In this manner we could have a viable space colony.

Do you still think that God is wrong about homosexuality??

I found this article after reading it then tell me. 65% engaged in heterosexual ?? that is incredible!!
Do you still think that God is wrong???

According to the tally of 40 foster-parents, 12 foster mothers sexually abused their charges, nine of whom molested foster-daughters, and 28 foster-fathers sexually abused their charges. The data showed that 18 percent of foster-fathers sexually abused foster-sons. Overall, 65 percent of foster-parent perpetrators engaged in heterosexuality and 35 percent in homosexuality with their charges.

Family Research Institute pointed out that homosexuals comprise between 2 to 4 percent of adults, as studies reported, "thus the figures above indicate a disproportionate amount of homosexual molestation."
The study is based on data provided by the Illinois Dept. of Children & Family Services and the Minnesota Dept. of Human Services.
