In the recent issue of the Economist, there were three significant articles that addressed significant, a really means significant, breakthroughs in three of the biggest polluting causes of Carbon Dioxide production. Worth Readings:
- In New Zealand a discover that a certain type of seaweed if put into the feed of livestock that produce methane gas (cows, sheep, etc…) can reduce their methane production by about 2/3rds. It is actually healthier for the cattle. This problem is one of the leading causes of CO2 gas build-up in our atmosphere and it appears that a new industry is now being built in New Zealand to produce this new seaweed in for feed-stock.
- In Australia, a company has figured out a way to produce concrete without the heavy CO2 product byproduct buildup in the atmosphere (may cause up to 5% of CO2 production world-wide). They have replaced the re-bar with fibers and change the chemistry of the curing process. The result is a better product that is lighter and will last longer with no significant maintenance. They are now tackling a huge bridge with this technology. It can apply to almost all concrete structures and as the advantage of no steel and therefor no rust buildup in bridges and other outside structures
- Ships are now installing bubble produces on the bottom of the ships. The ships ride on a layer of bubbles. This decreases the fuel consumption by reducing friction and has the benefit of reduction of costs for fuel of between 5-10%. Most cruise ships are now going in this direction and many of the commercial ships are moving in this direction as well.
This means that maybe our children and their children will have a better world.
