PV Gap

How many Megawatts of power does the Space Shuttle produce each second during flight?

We Answered:

First you have to get the terminology correct. Power per second is a meaningless concept as power is already energy per second.

What you want is the power it produces, OR the energy per second (same thing).

Total power on takeoff is about 12 GW, or 12000 MW. When the booster rockets burn out, this reduces to 2 GW from the main engines.

These rockets do NOT use liquid oxygen and hydrogen, that was the Saturn V used in Apollo moon shots.


edit, correction, the main engines DO use liquid oxygen and hydrogen, the boosters use a solid fuel

Landscape lighting - hard-wired electrical vs solar-powered?

We Answered:

To answer your question properly, one would need to know why you are wanting landscape lights & the location of those lights.

Most people only want a decorative effect & therefore don't need full-blown hard-wired lights. Good quality solars will be fine for them.
