Among the mitigation options for climate change are the so-called geoengineering projects, one of which is the placement in space of devices to deflect, block, or diffuse a small amount of the solar radiation hitting the Earth.

This is one of the most straightforward of all the climate control technologies–if Earth is trapping too much heat or the Sun is getting too hot, just block a bit of it. No matter the cause of the increased average temperatures on Earth, this solution will reduce them. Moreover, even if future needs require additional solar radiation to maintain temperatures due to some cooling event, the same shades or reflectors might be quickly redesigned and used for that purpose as well–the beginning of a global climate control system.

In the next century, the progress of humanity will proceed on the basis of how successfully we address the following six needs. They are not the typical needs of world peace, ending world hunger, or stopping environmental destruction that so often are vaguely thrown about in the press these days. Those are but symptoms of the real challenges that we must attack in the next 100 years. While they are related to some of those subjects, in different ways they are directed at more concrete, more measurable factors that will enable or inhibit our achievement of broader goals this century.

One of the real driving forces in any human exploration has been intense need. In the initial human migrations around the globe, people explored out of a need for food, and a need to be safe from other potentially hostile bands–there is safety in distance. During the European colonization period the nations and kingdoms of Europe felt an intense need for hard currency (gold) and other physical wealth (spices, gems, etc.) to support their mercantilist economic systems. In today’s world, many hope for human exploration of space in a noble adventure to make our mark in the galaxy, but what will really pull us off the planet will be our needs.

Recent news has highlighted the opening of the first commercial hydrogen fueling station in California. For people who lease hydrogen fuel cell vehicles (the most common user) or some kind of hydrogen combusion engine, they now have one public place in the state of California where they can refuel their vehicles. A few others already exist in New England and Washington, D.C. Is this the start of a new age in the technology of fuel consumption and the beginning of the end of fossil fuels? And, where does this hydrogen come from anyways? Let’s explore some of those questions in this article. Read the rest of this entry »

Drilling for Oil is not the only Potential Energy Producing Activity Offshore

While “green” or renewable energy technologies are often seen as the rival against traditional fossil fuel technologies in some kind of epic battle, they can actually sometimes enhance and support each other. Recent news from wind power companies suggests that they may be able to move their turbines offshore to deep water out of sight of land and away from wind-blocking obstructions by employing technology developed for deep water oil and gas exploration and production operations.

Recently, this article on CNN.com revisits the idea of collecting solar power in space and beaming it down to Earth. With such a large world demand for energy expected in the next 20 to 50 years, and declining costs for access to space, could this be the time for this science fiction technology to become a reality? As our costs continue to increase, geographically sourced resources are seen as unstable, unpalatable, or insufficient, this idea may finally have come of age. Read the rest of this entry »

With energy costs increasing faster than inflation and much faster than income in the United States, many have a desire to conserve. But, without information, our conservation may be more expensive than it is worth and hardly as effective as it could have been. The kill-a-watt electricity usage monitor provides a useful way to be smart about conservation. Increase the efficiency of your home. Read the rest of this entry »

As landfills which hold municipal solid waste are closed the emissions from decay of the material in the landfill becomes a pollutant. That pollutant can either contribute to smog and the increase in greenhouse gases, or it can be used as an energy source. A free, environmentally friendly fuel, potentially harmful if released, is not being used everywhere? What are we thinking? Read the rest of this entry »

This review refers to version 6.3 of IRCMS by NAVAIR (Naval Air Systems Command).

IRCMS 6.3 provides users with an aid to perform Reliability Centered Maintenance (RCM) analysis. RCM is a process by which the life cycle costs of performing maintenance on a system are compared to the consequences of not performing maintenance as well as other options. This is a free tool, available here. As it is free to download and test this tool, I will not go into every feature available, just what I have noticed as its strengths and weaknesses.

So, how long will it be before our trash is more valuable than existing iron mines?

The municipal waste collection system in the United States is very efficient at removing whatever materials we place in our trash bag. So much so, that we normally find it difficult to imagine the scale of the operation, and especially the scale of the mountain of material that is buried in our landfills each year. I wonder how long it will be before the sources of metals in our landfills is more valuable than our sources of metal ore. Read the rest of this entry »

Excuse me, are you going to use all that Sun in one place?

Given present-day concerns about energy independence, pollution control, and energy price stability, solar energy is often touted as one of the (at least partial) solutions to that problem. Solar energy involves making electricity or other useable energy out of light from the Sun. And while humans have been using solar energy on some level since before history, most applications including solar cells (photovoltaics) and other efficient conversion systems have only been in use since the late 1940s. As of 2005, the total share of domestically produced electricity from solar energy was very small at 0.065%, or a total of about 19 billion kilowatt-hours, but growing rapidly.
