Combating Malaria With Solar Energy

On April 25, people across the world took part in a wide range of activities to mark World Malaria Day 2013. In the same day a Dutch's institute, Wageningen University, began a four-year campaign called "Solarmal Project" to install more than 4,000 solar-powered mosquito traps at homes on Rusinga Island in Lake Victoria, Kenya.

Researchers are trying to develop a new toxin-free approach to combating malaria. They hope that this will not only eliminate malaria locally in Africa, but also provide the local population with solar energy. Mosquito traps containing "human odour" are placed to attract mosquitoes away from the houses. Once they have entered the traps, the mosquitoes will die of dehydration. This technology has eliminated the use of insecticides which would lead to a high level of insecticide resistance in the malaria mosquitoes, which makes fighting the disease increasingly difficult and harmful to the environment. The power supply for the fans in the traps is provided by solar panels on the roof, which not only guarantees that the traps will work but also provides the family with sustainable electricity for lighting and mobile phone charging.

Solar panels and mosquito traps will be installed on approximately 50 homes per week and an estimated 4,000 solar panels overall. The impact of the project will be monitored closely as its dual benefits of providing inhabitants with energy and potentially eradicating malaria would be groundbreaking worldwide.

USB Charger Powered By Water

A Swedish company named myFC invented PowerTrekk which uses water as the source of charging. PowerTrekk is a portable fuel cell charger for use when away from the electricity grid. It provides instant power anywhere to electronic equipment such as mobile phones, digital cameras and GPS devices.

PowerTrekk is a 2-in-1 solution that is both a portable battery pack and fuel cell. The portable battery pack can be operated on its own as a ready source of power or storage buffer for the fuel cell. The fuel cell enables instant charging from a deflated battery state without ever needing a wall charge.

How does PowerTrekk work?



1. Remove tray system and insert fuel pack into fuel compartment.

2. Fill-up water compartment (approx. one tablespoon) and close lid.



 
3. Re-attach tray system to your mobile charger.

4. Connect electronic device to the PowerTrekk.



 
5. A mobile charge will start automatically.

6. While in use, PowerTrekk indicates state of operation. Once your mobile charger is in shutdown mode, remove used fuel pack.



The estimated unit cost for PowerTrekk is said to be about US$229, and may see a commercial release date in the third quarter of 2013.

CO2 Levels Reaching 400 PPM For First Time In 3 Million Years

According to measurements from the Mauna Loa Observatory in Hawaii the Earth's atmosphere is right about to reach 400 parts-per-million (ppm) of CO2, a level that was last seen 3 million years ago. From the chart below we can see that the CO2 level is steadily raising since 1958 when the observation began.
According to the author of the source:

"The last time CO2 reached the symbolic milestone of 400 parts per million in the atmosphere - in the Pliocene era - temperatures rose by between 3 and 4 degrees and sea levels were between five and 40 meters higher than today."

Our world is approaching the 450 ppm level soon which is considered to be the point at which the world has a 50% chance of avoiding dangerous climate change. Any higher and the odds of avoiding searing temperature rises of 4 or 5 degrees by the end of the century become prohibitively risky.

Nokia Phones Received Most Customer Satisfaction In USA

According to an online survey of over 142,369 customer reviews published prior to March 30th this year, AT&T customers are extremely satisfied with their Nokia Phones. It showed that AT&T customers using Nokia phones report a customer satisfaction 21% above average across all major carriers and all major brands in USA.

Looking at the chart below Nokia seems to have the highest customer satisfaction amongst 2 out of the 3 mobile providers with HTC just edging them out on T-Mobile.
