A vigorous debate about alternative energy.
MIT Video has a "soap box" with Professor Donald Sadoway about the sources of alternative energy. The video discusses the majority of the alternatives that are "believed" to be available. And Dr. Sadoway dispatches some rather brutal common sense as to the viability of these alternatives.
The take away for me was the efficiency and ease of use of the internal combustion engine. Alternatives are not that easy, and they are certainly not within the scope of anything that is safe or affordable. Dr. Sadoway notes the following regarding some of the alternatives.
It was 1839 when William Grove invented the Hydrogen fuel cell. Today the costs and possibilities of this promising energy source are further then ever from being realized. I highly recommend watching the video by clicking on the title of this entry. It is a complex and difficult process that is best explained by Dr. Sadoway.
Batteries have experienced significant development over the last two decades. Fueling the laptop and cell phones to their prominence today. To power a vehicle however becomes rather costly. To travel 100 km would cost the consumer approximately $1 million in state of the art lithium ion batteries.
Dr. Sadoway responds to a number of questions from the audience, one being the viability of nano technology capacitors. These seemed promising yet many years away. Brief mention of Emery Lovins use of switchgrass and book "The end of the oil game" are, I can assure you, not cost effective at this point. To burn more energy then you produce seems somewhat counter productive to me. And that is what is required for switchgrass and corn based ethanol's. Just because of the large corn subsidies do these alternatives even get mentioned.
So what is the answer to the use of hydrocarbon based life style? I think there are three very good answers that promise the most value in the short to mid term. They are the increase in horsepower from the average internal combustion engine. To double the horsepower per gallon would reduce the size requirement of the engine and reduce the demand for energy. If each molecule of gas contains E=MC2 of energy, we are a long way from realizing the full value of each drop of gasoline. The second alternative is the Segway, and the third is the funding of this software to enable more innovation in the supply side.
In Formula One, the engines are as powerful as they were in the 1980's when they were propelled with 1.5 liter turbo specifications. Gobbling up gas at a phenomenal rate these engines were in race configuration capable of around 1,000 horse power. Today the use of normally aspirated 2.4 liter engineers generate almost 700 horsepower with spec gasoline and use less then 160 liters per race. This is directly comparable to the 3.5 liter engineers that were generating 500 - 600 horse power with exotic fuels at the end of the turbo era in 1989. In other words we have probably doubled the horsepower per drop of gas in the past 2 decades. How much more can be achieved in this area?
The Segway is faster then most cars in rush hour traffic. I'll leave Dean Kamen to explain the efficiencies of this transportation device that he invented on MIT video here. I think this type of rational thinking needs to be adopted. The prices at the pumps have done nothing to defer the desire for energy. The world is consuming 1.5 million additional barrels per day since this time last year. What price is necessary to stop the increase and reduce the demand? Obviously much higher. If the Segway can get 20 km on $0.50 of electricity, and get you to work faster, there is value in that.
