The energy consumption needs of technology
As late as 1993, high-tech paraphernalia like computers, printers and video games had a negligible effect on power usage. Today, it's estimated to account for more than 13 percent of a typical household energy budget. By 2020, it could be as much as 25 percent

Military sonar technology causes beachings
Submarines have been using low and mid-frequency active sonar technology, a deafening soundwave that is dangerous even 300 miles from it's source. Some mid-frequency sonar systems can put out over 235 decibals, which is about as loud as a rocket launch.
Animals for hundreds of miles literally jump out of the ocean to try to avoid the sound. The damaging effects vary, bet are akin to decompression sickness causing internal bleeding and bursting organs including lungs and eardrums. When beached dolphins are reported this sonar technology is rarely mentioned in the news, although the link has been demonstrated.

LFA is low frequency active sonar
LFA stands for Low Frequency Active sonar, a technology used by submarines to "see." Unfortunately even one hundred miles from the source of a LFA source animals experience the equivalent of decompression sickness, killing every dolphin, porpoise, orca, and whale within 100-300 miles, depending on the decibal. It's no good for humans either.

What are the different types of laptop batteries?
There are currently three types of batteries commonly used to run people's laptops:
1) Nickel Cadmium (Ni-Cd) batteries were the standard technology for years, but are now out of date.
2) Nickel Metal Hydride (Ni-MH) batteries are a cadmium-free replacement for Nickel Cadmium.
3) Lithium Ion (Li-ion) is the battery you want for your laptop and is the current standard for portable power.
