How to solve poor power problem or how to improve my power quality?

December 29th, 2008

For our industry due to shortage of power we have provided generator (now running with generator), machines are operating from the generator power. But we have power quality problem there, we have not installed capacitor bank to improve generator power. Do we have any problem if we add capacitor bank panels to improve generator power. [...]

I used to practice every day, but ever since we had a baby I've been too tired. How can I get more energy?

December 29th, 2008

I've been doing Wing Chun Kung Fu for over a year. My wife and I had our first baby a couple months ago, and ever since then I've been exhausted all the time. Before the baby was born, I was practicing every day for at least 30 minutes. But now I'm just so tired that [...]

How efficiently do plants use solar energy when compared to solar panels?

December 29th, 2008

How does the amount of chemical energy stored in plants compare to the electrical energy stored by solar panel/batteries? Most plants are around 1% efficient at turning sunlight into a useful form of energy it can use. Bamboo is probably somewhat higher. Solar panels are somewhere around 20% efficient now I think. Trees are much [...]

How do companies emit greenhouse gases / how can alternative energy be applied?

December 29th, 2008

I was recently discussing with someone the possibility of the government installing a cap-and-trade system on American companies to reduce greenhouse gas emissions. I said that would be a baby step in the right direction, however I think we need a stricter solution, such as the development and eventually mandated uses of alternative energy (solar [...]

Why is the power to tax a concurrent power?

December 22nd, 2008

Why is the power to tax a concurrent power? Should collecting taxes remain as a concurrent power? Explain. I think it's related to the fact that taxes are collected by the city, the state and federal gov. concurrently (meaning "at the same time"). As long as the government has a local instance and a nation-wide [...]

Has there been any study to determine the energy a bird spends in flying?

December 22nd, 2008

If so, can this energy expenditure be extrapolated to determine the energy required to fly a single human being in a way similar to those of birds? I'm curious to know if the energy required for such an endeavor would be higher than what is currently used by fixed wing planes. The problem is, birds [...]
