Wood gas vehicles: firewood in the fuel tank

During the Second World War, almost every motorised vehicle in continental Europe was converted to use firewood. Wood gas cars (also known as producer gas cars) are a not-so-elegant but surprisingly efficient and ecological alternative to their petrol (gasoline) cousins, whilst their range is comparable to that of electric cars.

Making society forecast-proof

Because forecasts of abundant fossil fuel supplies far into the future have been embedded in public policy and business planning worldwide, we have made our entire global society dependent on getting these forecasts right. If they turn out to be too optimistic, then we could all be in for serious trouble. Since long-term energy forecasts–and really any long-term forecasts–are difficult if not impossible to get right, perhaps we should consider making society forecast-proof insofar as that is possible.

The Meaning of Copenhagen

It was the pivotal international conference of the new century. Tens of thousands showed up, including heads of state, officials at all levels of government, representatives of environmental organizations, and ordinary citizens from nearly 200 countries. Scientists had warned that, without a strong agreement to reduce carbon emissions, the consequences for civilization and the world’s ecosystems would be cataclysmic.

The problem of induction and the blindness of fools

One does not have to know anything with certainty in order to decide on policy. In fact, policy is always based on incomplete information about the past and guesses about the future. What policymaking requires, especially in critical areas such as future energy supply, is humility and therefore caution.

Peak oil, prices, and supplies – Dec 23

-OPEC leaves oil production unchanged
-EIA Energy Outlook 2010 Reference Case Projects Moderate Growth in US Energy Consumption, Greater Use of Renewables, and Reduced Oil and Natural Gas Imports

Managing the Peak Fossil Fuel Transition: EROI and EIRR

Current renewable energy technologies must be adopted in conjunction with aggressive Smart Growth and Efficiency if we hope to continue our current standard of living and complex society with diminished reliance on fossil fuels. These strategies have the additional advantage that they can work without large technological breakthroughs.

Trolley canal boats

For many centuries, canal boats were propelled by men, horses or mules on the towpath beside the water. Before diesel power took over, engineers developed several interesting methods powered by electricity: trolleyboats, floating funiculars and electric mules. Many of these ecological solutions could be applied today instead of diesel engines.
