Seyoum Goitom

Seyoum GoitomSeyoum Goitom is a 38 year old inventor from Eritrea that has designed and built a number of eco-friendly devices.
He is one of the most experienced and talented mechanics in his home town, in spite of not having attended any kind of technical college. Seyoum taught himself nearly everything he knows about repairing gadgets.

Seyoum got funding from the Dutch embassy in Eritrea for his latest idea: a solar powered cooker.
He is convinced that the cooker will interest enough of his fellow country men, and in the long run, it will help to stop cutting down trees for firewood.
Some 95 percent of Eritrea’s forests have already been lost in the past century because of drought, a growing population and during the war for independence from Ethiopia.
The most significant environmental problems in Eritrea are deforestation, desertification, soil erosion, overgrazing, famine, and damage due to the infrastructure from warfare.
Widespread deforestation, which is one of the the main causes for desertification, is also a major threat to Africa’s most vulnerable communities.

Seyoum Goitom's Solar CookerSeyoum uses an old satellite dish covered in tin-foil that has been converted into a solar cooker.

Solar cookers are devices that heat food using only solar energy.
Since they use no fuel and they cost nothing to run, many humanitarian organizations are promoting their use worldwide to help slow deforestation and desertification caused by the need for firewood used to cook.
Solar cookers can be also used in outdoors cooking, especially in situations where minimal fuel consumption or fire risk are considered highly important.

Most solar cookers work on basic principles: sunlight is converted to heat energy that is retained for cooking.
Sunlight is the "fuel." A solar cooker needs an outdoor spot that is sunny for several hours and protected from strong wind, and where food will be safe.
Obviously, solar cookers don't work at night or on cloudy days.
Solar Cooker
Dark surfaces get very hot in sunlight, whereas light surfaces don't. Food cooks best in dark, shallow, thin metal pots with dark, tight-fitting lids to hold in heat and moisture.

A transparent heat trap around the dark pot lets in sunlight, but keeps in the heat. This is a clear, heat-resistant plastic bag or large inverted glass bowl (in panel cookers) or an insulated box with a glass or plastic window (in box cookers).

Curved concentrator cookers, such as the one shown in the illustration, typically don't require a heat trap .

It pulls together all the bits and pieces (CD player, amp, CDs, extra batteries, cables) for a boundless little portable system. Whatever your on-the-go activities may be (biking, walking, traveling, or enjoying the great outdoors) the AirBag makes listening to tunes amazingly easy.

The AirBag has two main compartments.
The front compartment (the "lid") holds the Total Airhead or Total BitHead amp snug as a bug in neoprene casing. The lid also holds up to 4 spare batteries.
The main ("bottom") compartment holds the CD player with a large strip of Velcroe, and includes 4 sets of adhesive Velcroe loop velcoins to secure the player in place. The bottom compartment also includes an additional pocket with 5 prosleeve CD holders which can hold a total of 10 CDs.

In order to connect your AirHead to your CD player, convenient openings at the base of the lid allow you to run the mini cable into the main compartment.
The AirBag includes a detachable shoulder strap. A Security Strap is also available for the AirHead that hooks to the bottom of the bag to run around your waist. The Security Strap not only keeps the bag from moving around on your waist but also eliminates the risk of theft while you are roaming around those sketchy airports. For all those adrenaline junkies out there who love their extreme activities, Extreme Suspension System secures your AirBag to your chest or back.

The AirBag is 6.25" (17cm) long, 6" (15cm) wide, and 1.25" (3.5cm) high, allowing it to fit pretty much any portable CD player (except for a few older models that weren't so svelt). The front pocket is 6"(15cm) wide and 6"(15cm) long, and stretches to a height of over an inch. The AirBag weighs only 7 ounces when empty, while all loaded up with your CD player, AirHead, batteries, and cables, it weighs about 1.5 lbs.

MP3 Player Comparisons

Confused about what MP3 Player is best for you?
I was too.
Watch this video and become even more confused :)


Paying a visit to cnet.com might help you decide.
"Every month, manufacturers unleash even more MP3 players to an increasingly confused public. Not only do these devices have wildly divergent features, but ongoing format wars mean the MP3 player you choose dictates where you can buy your digital music. These devices are anything but one-size-fits-all."
There you can read a Buyer's Guide for the different types of MP3 players, divided into the following categories:
  • Hard-drive-based
  • Micro hard-drive-based
  • Flash-based
  • MP3 CD
http://reviews.cnet.com

But as Barry Schwartz (Sociology Professor at Swarthmore College and author of "The Paradox of Choice"), explains in the video below, the problem is "how and why the abundance of choice in modern society is actually making us miserable."

Laser Eye Surgery Videos

A number of innovative Laser Eye Surgery procedures are widely available today.
There are three main types of Laser Eye Surgery:

PRK (Photo Refractive Keratectomy) has been the standard eye laser surgery for many years.
It involves the complete removal of the epithelium or the outer layer of cells on the eye, with the use of a "cold" laser light.
PRK is mostly used on patients with low to moderate amounts of Myopia Astigmatism.
Below you can watch a video showing a PRK surgical intervention:


LASEK (Laser Assisted Sub-Epithelial Keratectomy) or EPIFLAP (Laser Assisted Epithelial Keratomileusis) surgery involves the fractional removal of the epithelium to reveal the cornea, which is then firmed or reshaped by a laser. The outer layer of cells is then pushed back, and the eye heals shortly after.
LASEK is used on patients with low to moderate amounts of Myopia or Astigmatism.
Below you can watch a video showing a LASEK surgical intervention:


LASIK (Laser Assisted in Situ Keratomileusis) is the newest and most popular type of eye laser surgery. Initially developed by Spanish ophthalmologist José Barraquer, with this procedure a thin layer of the eye's cornea is sliced off to create a flap. This enables the laser to target the tissue underneath. The flap is simply replaced and grows back naturally. Vision is restored almost immediately.
LASIK is usually used on patients with severe Myopia (nearsightedness): -0.75 diopters to 10.0 diopters.
Below you can watch a video showing a LASIK surgical intervention:
