March 8, 2014 - This is a great time to be an astronomer. It appears we are discovering exoplanets by the boat load and we are finding out that solar systems, some like ours, and some bizarrely different, seem to be the rule and not the exception.
March 8, 2014 - For several years I worked with an Australian company developing a new skimmer technology for remediating oil spills. That got me very interested in this subject area. So I keep my eyes open for new technological innovations that can address what remains an industry-wide problem for fossil fuel and transportation providers.
March 6, 2014 - I am finally back from Florida and once again sifting through the content my web crawlers and affiliations with social networks that provide me with the fodder I turn into 21st Century Tech blog.
Seth MacFarlane, the multitasking comedian and creator of Family Guy, and other raunchy fare, happens also to be the driving force behind the new version of Carl Sagan's classic science show COSMOS, which will appear Sunday on Fox and simultaneously on other networks, hosted by Neil deGrasse Tyson. I know a number of the writers and producers who have striven to create something stunning, vivid and updated for the 21st Century.
I care about the environment just as greens are supposed to, but I see dogmatic, poorly thought through green policies as a big part of the problem facing the environment. With the greens as its friends, the Earth needs no enemies. Today, I read that solar companies are leaving Spain, where it is usually sunny, to come to the UK, where it usually isn’t, because our previous and existing governments were very keen to demonstrate their green credentials by subsidising solar power. This is obviously counter-productive, as are many other policies thought up by the green community.
My friend Jon Foley, whom I have a great deal of respect for, has a piece up arguing that GMOs have failed to improve global food security because they fall into a trap of reductionist thinking.
With due respect to Jon, I see this a different way.
February 25, 2014 - We know today that CO2 is reaching the threshold of 400 parts per million in our atmosphere. We are told that this component of greenhouse gas emissions (GHGs) is the main measure fcr determining human influenced climate change. There are, however, other potent GHGs. One is methane (CH4) and like CO2 it also is studied.
February 24, 2014 - The answer is poo. But before I explain further let's look at what bioreactors are all about. For example, you are a bioreactor. You convert food and oxygen and other inputs into energy and you eliminate what you don't burn. All life on the planet is governed this way - intake, convert to energy, eliminate. And what gets eliminated still contains lots of energy potential.
Very briefly, increasing population and wealth will generate higher resource need until the resources needed per person starts to fall at a higher rate, and it will. That almost certainly means a few decades of increasing demand for many resources, with a few exceptions where substitution will impact at a higher rate. Eventually, demand will peak and fall for most resources. Meanwhile, the mining industry can prosper.
