Interesting story about the perpetual motion machine. Reminds me of a discussion Once I had with a friend about putting Piezo electric transducers into the tyres of automobiles to generate "free" energy :). One point to be noted is that for plug-in hybrids, the batteries can be directly charged from a power outlet. So the energy consumed may be cleaner based on the source of electricity. In any case I feel Fuel cell/Fully electric vehicles will overtake HEVs in future.

Unless the energy density problem is solved, no. Hybrid cars fit only certain peoples needs, never mind tastes and I doubt the public wants to ride the volume/cost curve to where they are price competitive with say, a toyota corolla. My dad owns a Prius, I though it had a cool dashboard. However on the highway the wake of a passing tractor trailer truck made the car lurch more than I was used to. He said it was normal, I rolled my eyes.

There's a lot of room for wringing out efficiencies in internal combustion engines and improved transmissions.

I'm one of those guys who drives a suburban assault vehicle. I like it; I hope never, ever to hit one of those teensy weensy toy cars with my FJ Cruiser. It's not my ego that bought the FJ... it was the desire to wrap my family some old-fashioned safety (steel) and some new-fashioned safety (airbags everywhere). Also, I have been long skeptical of the overall economy and "green-ness" of hybrid vehicles, mostly because I'm a battered and cynical old engineer, and I know that not only nothing is free, but almost everything has hidden costs. In hybrid vehicles, the hidden costs, as pointed out, are horsepower (say, to tow a trailer), size (to reduce drag), and cost. Heck, my Corolla gets about 30 mpg on the highway: what would I have to pay for a smaller hybrid? All-electric cars, we note, just move the point of fuel combustion to a centralized source, the power plant, which is a bad thing unless your power plant happens to be fired by uranium. And battery manufacture is reportedly quite dirty. Most of it's in China, though, so that's ok: the US tree-huggers don't see those plants. Out of sight, out of mind. I will continue to burn fuel in my SUV as much as possible, to hasten the day that there's no gasoline available: at that point, all of the wacko (and merely wishful) energy schemes can be put into place, and then, I suppose, a utopia will arise.

All over the world auto enthus are interestingly watching the developments taking place in the Hybrids. i am also one among. It is interesting to note that ICE has a optimum point at whcih this is highly efficient and ICE works around that point in the hybrids and charges the battery. This concept is great. My thinking goes far beyond this. Hybrids uses two level energy convertion gss to electricity and electricity to motion energy. Even though engineers had optimized the system for fuel efficiency and higher power when it comes to maintanance part this is highly expensive, The initial investment also higher and i do not see a big attactive crowd to buy these. In India 2 years before a leading company launched the hybrid and after 6 months time the price was brought down by 33 percent. This is quoted here as a reference for the demand of Hybrids. Later at a point of time when the pollution levels are imposed by the governments to a lowest level hybrids will win the market place

What? There is no free lunch? There is no something for (almost) nothing? The laws of physics can't be bent to our desires and dreams? I am shocked and saddened....

Sure there is. The munchies at a bar, after you pay for your drinks. Wind power, after you invest $750 million into the 20-odd fans. Solar power, at least for your i-Pod. (Well, ok... you can get a lot more power than that... you can power your house if you cover Rhode Island with collectors.) Waste oil fuel. Fuel from food, er, corn. The depressing thought is that the laws of thermodynamics are the best possible case... not something imposed by grumpy engineers or greedy manufacturers so that you can't have your 200 mile per gallon carburetor.

This was really difficult article to read and to me it looked incongruous. In beginning law of conservation is revisited. This may be mystery only when you are in middle school. Also, as for plug-in hybrid the concept is explained very well by media – for average user, battery charged from mains will suffice their daily needs. Only when they exceed the range of battery charged, they need help of fuel. Also for any new technology, there are advantages and some disadvantages. Author misses to compare and contrast them from current and future prospects. I hope they are covered in part II. Please correct me if got it wrong.

Bob, you are my hero. It's people like you who are willing to brave ridicule from tree huggers & the like and make a personal sacrifice by buying up extra gas every time you fill up, removing just a little bit more of the finite fossil fuel supply than others are willing to, causing the price to go up, making green energy that much less uncompetitive. Doing the right thing isn't always easy, but you're sticking to your guns, and that's an inspiration to us all!
