Interesting discussion on the diffusion of solar energy around the world and especially in the US. The main point is: is solar energy a valid energy source, and is just in need to have some economies of scale and learning to kick in? If so, government subsidies may be helpful... but don't they bring the risk of locking us into a wrong technology, or simply the wrong technological generation?

Interesting take the the news that space tourism is about to take off. The author's position is that the real business model by private companies will not (only) be to take wealthy people in orbit. Rather, it will be to take up the routinary and menial task of shuttling men and equipment to and from orbiting space stations in a more efficient way than governmental space agencies, with efficiency coming from competition. This will free up government agencies to pursue projects that are clearly beyond what private firms can do, i.e. going to the moon and Mars.

"Green" energy is a trickly field for innovation. Energy is a pure commodity, and the market will never choose green over carbon-based energy unless it is cheaper. But green technology will not get to that point of maturity unless government introduces subsidies and/or carbon taxes. True, this is a cost for today, but also a potential driver of economic growth for the near future and for even greater benefits further on. The problem - of course - is in balancing benefits and cost.

Photovoltaic panels are apparently following a nice s-curve, with 100% year-on-year growth. But this has happened  mostly because of public  subsidies, which are about to be reduced, also because cash-strapped governments will not be able to bear the burden of generous feed-in tariffs in the future. The impact is likely to be critical for highly-levered operators, who will find it difficult to service their debt, and for PV makers, who are likely to discover that the industry has a serious problem with oversupply. Add the likelihood of some breakthrough innovation leading to a new generation of cheaper and/or more efficient cells, and you see a critical investment case.

Short article commenting on the role of markets in allowing experimentation, chaos and ultimately innovation... sometimes that planning and government intervention cannot properly achieve. Nice reading.

Article on the complemetary role of public and private financing in supporting technology in the early phases of its lifecycle. Financing is a mixed blessing, since it is necessary to make technology viable, but it risks supporting the "wrong" technology or dominant design

German Chancellor Dr. Angela Merkel is trying to mark the future of the electric and hybrid vehicles founding the "National Platform for Electric Mobility" - a new alliance dedicated to promoting sustainable mobility. A clear objective: she wants to take electric mobility out of its niche model status and become the market leader for a new type of sustainable mobility by 2018. This strategy is planned by the German federal government, which would like to to promote electro-mobility and to see about one million electric vehicles on the roads by 2020. It's a clear way to force the German carmakers for reshaping mobility. The market needs innovations that are intelligently coordinated and networked, from the engines themselves to a reliable infrastructure (charging points) and well-trained experts who can deal with highly complex technologies.

Toyota's recent response to claims of unintended acceleration in its vehicles illustrates the potential pitfalls of today's technologically complex automobiles. Software development, however, is still largely stuck in a 1970s pre-kaizen mode, where the human-readable instructions are accessible only to those who write the code. This protects the intellectual property of the software developer, but it also limits the abilities of others in the value chain to "see something, say something, and do something" to correct flaws. The lack of visibility into the software in its cars stands in stark contrast to the openness of its management and manufacturing processes. The software hidden in Toyota's black boxes is the equivalent to having a car with its hood welded shut. Open source represents the most significant change and most disruptive force in software development in 20 years. In the open-source software model, the human-readable source code is distributed along with the computer-readable machine code. Users are encouraged to understand the code, find flaws, suggest fixes, and add functionality. Open source is about leveraging the power of participation to solve complex problems such as manufacturing, health care, and government. It may also be how Toyota can improve its vehicles and ultimately regain consumer trust.
