Renewable Energy At Home

I am curious about the amount of electricity needed to produce/operate a wafer fab. I hear about how much power is used by the computer chips, but have never seen the amount of power needed to make the chips themselves. Well, it depends. Are you talking about the whole process from crystal growth to chip [...]

A simple pendulum has a length of 0.75 m and a bob with a mass of 0.15 kg. The bob is released from an angle of 25 degrees relative to the vertical reference line. a) Show that the vertical height of the bob when it is released is h= L(1-cos25 ) b) What is the [...]

Some places rely on solar and wind energy right? To power their homes and such. How do they use energy in the night or when there is no wind? Do they have something that stores the energy like a big battery or something? I have to “make” a green city and it will use renewable [...]

What's with the right-wing propaganda to paint Obama as subserviant to the Saudis, like Bush was? I don't get it, either. Here are two Presidents: One bows to a Saudi King, and the other practically makes out with the Saudi King. The first President wants to reduce dependence on Saudi oil, the second comes from [...]
