Dolores Said:

what would be the total amount of energy radiated by the accretion disk during the history of the black hole?

We Answered:

solar mass = 2x10^30 kg

E = mc^2
E = 10% * 3x10^9 stars * 2x10^30kg/star * (3x10^8 m/s)^2
E = 5.4x10^55 J

Luminosity
E/?t = E/10x10^9year *year/365days * day/24hour * hour/3600sec
1.7x10^38 Watts

According to this http://www.daviddarling.info/encyclopedi… , the luminosity of the Milky way is 10^44 dyne/s = 10^49 Watts

Gundam 00 Mobile Suit History Question?

We Answered:

i could be wrong but i think mobile suits have been around for about 150 years or so, since Aeolia founded celestial being over 200 years ago.

mobile suits may have been created after the construction of the orbital elevators.

there was a space expedition to jupiter that was mentioned to have been made around 150 or so years ago, which was suspected to have been the time when celestial being started construction of the solar furnaces.

Solar powered water well for agricultural use?

We Answered:

Here are a couple of sites for you to look at. I would think you would be better off using a lower HP pump (rather than the much more expensive 25+HP pumps) and irrigating from a storage tank rather straight from the well. There a lot of solar powered pumps with 25+HP up to 75 HP but they are expensive.
