Lightning from Clouds : Answer for our energy needs ?

Aaah the storm ! strike.. thunder..  what was that i missed ?  A tera million volts of electricity just zipped through and I just saw it disappear right in front of my own eyes.. and I didn't see it coming. and another one just a few miles across.. they are just all over.. so much charge, just gone in a moment ? well how much was lost ? a tera million volts or more ? What did we even lose ? what we lost was what we didn't capture.. wel how could I .. It is so immense and momentary and how could I reach to it and where could I store that all ? i just don't know. This is exactly whats going on every scientist's mind when the lightning strikes.. Alas I wished an idea flashed as well to bring this dream to fruition..

All that we need is a reservoir that could store this energy or an energy in converted form. Some of the ideas are to use the energy to create a hydrolysis of water and separate hydrogen and oxygen , store them for use later. Another possibility is to store this energy in large capacitors.
If that cant be done,  use the energy to melt a metal resorvoir with hi specifc latent heat and use the hot molten metal to produce steam; in a way thermal power..

Whatever the solution, the chances of beign able to use the power for a cleaner energy is definitely tue.


Is a Paperless economy really 'Green' ?


With Global warming fears increasing, 'save-the-earth' proponents are rapidly embracing e-mail storage as the 'go-green' option in place of using paper.

I sometimes wonder if this affinity for e-storage really amounts to saving trees and is an environment friendly step. Give it a serious thought and it looks like it is not really true.
Besides the benefit of being able to search for the information we need from these archives of data, they are causing more harm than benefit sitting there in the massive servers of corporates and the free e-mail service providers and your own personal PCs and Macs.

Well lets see how. More than 90% of the data we accumulate and stash away is never used. Think about it. All your e-mails are just lying there from several years. Is there a reason why you should continue to store it when you are sure that you wont need it again ?

Most of the electricity that we use comes from thermal power plants. It requires over a tonne of coal to provide enough electricity for 10 homes a day. Server farms where the data is housed have huge electricity requirements to be able to run the servers adn continue to store the data, run the air conditioners etc. And again these servers are doing nothing much but guarding the trash of e-mails and fies that would never be required by us. Statistics show that to store an MB of data for an year, an lb of coal is required. and all this leads to burning more coal and more greenhouse gases being let into the environment.

As much as we reduce the consumption of paper, one must make an honest effort to clean up all the trash email and just delete them all.

If you truly care for the environment, do it today, do it now.

Clean up those trash emails from your mail box !
