Wind Power Revolution

29 05 2009


Ever considered having a wind turbine? What if you were told you could build your own device to harness the wind power which were ten to thirty times more efficient and cheaper than building your own wind turbine?

Well look no further, the next wind power has arrived. And it’s called Windbelt.

Solar Powered Stirling Engine

20 05 2009


Given the rise, in recent years, of liquid fuel prices and concerns such as peak oil and climate change, it is no wonder there has been a tremendous interest on new ways to produce energy. Today we would like to share one that we have found out about: Stirling Engines.

A Stirling engine is a device that converts heat energy into mechanical power by alternately compressing and expanding a fixed quantity of air or other gas (the working fluid) at different temperatures.

Seed Bombing

17 05 2009


After the past article on how a bacteria could help stop desertification, here comes some other news on alternative ways to solve the same problem. This new idea is called Seed Bombing, which involves a bomber aircraft and charges full of the Seed Capsules. Essentially the project involves artificial dispersal of seeds over arid areas where natural vegetation has lapsed due to man-made follies like deforestation leading to desertification. Each capsule contains artificial soil and seeds, and are air-dropped over the selected regions.

Climate Change: Debatable

13 05 2009


After all the media time dedicated to Global Warming and the new proposals to stop such apparent threat, little is often heard about voices that have tried to explain logical inconsistencies inside the IPCC Man-made Global Warming theory. This is why Eco Wanderer wishes to present its readers with the other side of the argument, and ultimately let the readers make their own logical conclusions from analysis of the information.

The article will now present 4 pertinent arguments that point out inconsistencies in the current widely accepted theory that Man is responsible for the increase in the average temperature of the Earth’s near-surface air and oceans since the mid-twentieth century and its projected continuation.

Bacteria can prevent Desertification in the future

9 05 2009


Desertification is now a widely recognized problem that can negatively affect many people’s lives. It’s occurrence not only reduces the amount of farmland available, but also widely affects the biodiversity that existed in that habitat. This is why possible solutions for the problem (besides preventive factors) are of great importance both as a method to prevent any more harm done to natural resources, as to the local people that now has to live in more hard-enduring conditions

This is why the incredible idea of Magnus Larsson, a student from London’s Architectural Association, presents one of the most ingenious and potentially effective ways of dealing with this problem. His solution: a 6,000 km long wall of artificially solidified sandstone spanning the Sahara Desert from east to west, where the combination from the sandstone and the dunes will provide a refugee housing and a block against the desert.

Bioelectricity as the new alternative to Ethanol

8 05 2009

Due to awareness on the scarcity of fossil fuels and increased media coverage regarding global warming, alternatives such as Biofuels have gained an increased attention worldwide. However, researchers writing in the online edition of the May 7 Science magazine have now come to the conclusion that using ethanol to fuel our cars might not be the best idea after all.

Since growing energy crops are likely to compete with food crops for fertile ground, which would lead to the clearance of more forests to increase farmland, the researchers claim to have found a better alternative: convert biomass to electricity rather than ethanol.

Example of a “blogger” plant, where its bioelectrical signals are used to issue posts at a blog in Japan

Ted Talks: How to grow your own fresh air

8 05 2009

Recently on Ted Talks there has come an interesting story told by a man named Kamal Meattle on how we can use natural plants like Areca Palm, Mother in law’s tongue and Money plant to improve the health conditions in an enclosed space.

Apparently all one would need to have would be 4 Areca Palm‘s per person to replace CO2 with Oxygen, 6 to 8 Mother in law’s tongues per person in the bedroom (thus converting carbon dioxide to oxygen during night), and a few Money plants to help remove volatile chemicals from the air, to live in a closed environment and never need any outside air.
