Re: pic: MARS 1523: Our New Tesla
Yay, a debate!
Oh, wait the topic is on the feasibility of marketing and mass producing an electric car... Well, I'm not a statistician, so I really shouldn't speak about the statistics of the issue. I'm not a marketing guy, so I can't speak to the issue of selling them. I'm not a civil engineer, so I can't speak to the grid requirements. However, I am a car enthusiast, and I can speak to the fact that driving a Tesla was one of the most incredible experiences I've had, and puts any doubt out of my mind that electric isn't good enough for America. |

Re: pic: MARS 1523: Our New Tesla
Every alternative energy drivetrain has roadblocks. True.
Why not focus on developing better engines of your favorite variety (diesel or gas)? Because at some point, it becomes economically non-viable to do so. If it was economically viable to engineer an engine to have 60 MPG right now, you can bet that somebody would have done so! But at the present time, it's not economically viable. Give it a couple of years or so. Why are people working on EV technology? Because it may not be economically viable right now, but it's getting very close. As soon as it is, you can bet that the companies that currently have the technology to make EVs will be making money hand over fist, as they'll either have the market-ready stuff, or they'll be making a lot in patent royalties from other companies that are building EVs using their technology. And, what they're working on can improve the hybrids. The obstacles to an EV are simple: Range (how far you can drive without charging), Price (those batteries are expensive), Charge time, Performance, Size/weight. All of those are improving. |

Re: pic: MARS 1523: Our New Tesla
I find it slightly funny this topic shifted to a discussion on electric vs gas cars.
Neat picture. Would've been nice to get a shot of the motor (guess I can't call it a "engine"), but I would've been to excited to worry about pictures. Very cool. -Tanner |

Um climate change will never end! It is defined by changes in weather patterns.

Energy can be neither created nor destroyed, it can only change form. And every time it changes form, nature takes a tax in the form of heat. 1) Hydrogen is the smallest atom, building a "cage" to effectively contain it is nigh impossible. It is also one of the most corrosive elements. 2) What process are you going to use to get your hydrogen gas? What would be its efficiency? In this process, there will be more pollutants than just "water". In films, we often see car crashes that result in spectacular "explosions". That, like sound and fire in the vacuum of space, is a cinematic conceit. But if we had hydrogen fueled vehicles, it would become a reality. And then some. The internal combustion engine has achieved an impressive state of the art efficiency and will be hard pressed to go beyond 50 mpg unless we can find a way to enclose all roadways in vacuum tubes. (exhausting the heat energy then becomes an issue )Hybrids are effective at converting kinetic energy to electrical and back again with a small tax in heat to provide the same efficiency in the stop and go drive in a city per the highway. However, the environmental cost of the batteries is no small consideration. The previous post regarding pumped and centrifugal storage for peak vs. non-peak supply provides a good idea. Volvo is working on a hybrid that stores braking energy in a small centrifugal storage unit. It is mechanical, lightweight, and has little of the environmental drawbacks of battery storage. http://www.matthewsvolvosite.com/vol...e-braking.html There is also work being done with Ultra Capacitors that store the electrical energy physically vs. chemically. This is also better than batteries in that they are lighter. However, bridge the gap and you could be killed. Emergency workers have been trained on using the "Jaws of Life" to free accident victims in hybrids. Cutting the cables on a hybrid vehicle with their higher voltage systems is an issue. http://gas2.org/2009/01/25/dont-get-electricuted/ So, to forestall the inevitable DT's of our addiction to fossil fuels. Nuclear plant baseloading, Wind and solar supplements spread around the grid in our homes and communities. Geothermal heat pumps where practical and solar street lights. Of course, none of this will matter after 12/21/12 , but just in case, we can prep. |

Re: pic: MARS 1523: Our New Tesla
My envy is so incredible right now. I could just imagine a Tesla for my team in hunter green and black, and with accents of gold and white.
