Lebanese start to face unprecedented water problems

Standard

Water shortages due to low precipitation levels and lack of nation-wide water management

Lebanon has long been a country abundant in water and as such most Lebanese have taken water for granted thinking that they will never have a shortage in or problems with it.

It was apparent that this year has had very little rain [1,2]. Indeed the numbers indicate that the precipitation levels have not even reached half the average annual of 900 ml. This, of course, has led to a huge deficiency in water reserves [3,4]. But the main problem does not lie in the low precipitation levels this year rather it lies in the incompetence of the Lebanese authorities “and most Lebanese” to manage and conserve water.

On one hand, the authorities have not been doing their job of investing in the main source of life by managing the water (and sewage as a matter of fact; see below on this) in order to effectively exploit it and not waste it. They have not been working on conserving this abundance in water by preventing leakage, building dams, replenishing underground reservoirs, introducing artificial ponds, or dealing with the r
andom wells being dug and un-licensed water suppliers.

This is demonstrated in what Claude Tabbal, an expert on the water resources in Lebanon, said to Azza el-Masri and Raed Khalil of the Al-Akhbar newspaper [4] on June 26:

”We get 800 cubic meters of water per year, but up to 65 percent of it is lost each year”

Wireless data transmitted through light bulbs [TED]

Standard

Below is a very interesting TED talk by Harald Haas from July 2011 on the use of light (and light detectors) to transmit digital data. I watched this video in August 2011 and just watched it again from my downloaded archive. This is really interesting.

It is worth noting, as Harald mentions, that data is transmitted as electromagnetic waves. And to those who are not aware light is an electromagnetic wave.
