Is This the Car of the Future? Let’s Hope!

I came across an interesting article about the Tesla Roadster, a battery powered sports car that is able to go from 0 to 60 in a little over three seconds.

While hybrid cars are the current rage, they still have one fatal flaw – they still need gasoline. Regardless of the fact that hybrids get outstanding gas mileage, they are in essence just biding time until we find reliable vehicles that run on something other than a fossil fuel.

That’s where cars like the Tesla Roadster come in:

“The Tesla Roadster is powered by 6,831 rechargeable lithium-ion batteries — the same cells that run a laptop computer. Range: 250 miles. Fuel efficiency: 1 to 2 cents per mile. Top speed: more than 130 mph.”

While the 250 mile range isn’t exactly great, when I look at the above quote, it’s hardly the number that stands out. As you are all well aware, I love to save money, and I’ll be the first to admit, I would be one happy dude to have a car that costs $.02 per mile to run.

Let’s say I have a car that gets 30 miles per gallon. Since fuel is roughly $3.00 per gallon, it costs me about $.10 per mile to run my car. If I drive 10,000 miles per year, that’s a cost of $1,000 per year.

Now, lets say I have this Tesla Roadster (click here for pics). That 10,000 miles would only cost me $200. Think of what you could do with an extra $800.

Or, I could just go out and get a car that gets 150 mpg and call it even.

Unfortunately, I have a feeling these car’s aren’t going to be as inexpensive to buy as they are to operate, but that’s a different story for a different day.

    You can put that $800 toward the 1,600 laptop batteries you’ll need to replace after about a year and a half. You should be able to but 8 of them with it.

  2. Not a big fan of lithium batteries?

  3. as i read of the Tesla, it seems that part of the design is to create an environment that lets the lithium ion batteries last longer than they do in laptops, through air conditioning the batteries and coolant. I assume that the design issue would be, from the outset, to create an efficient car, and efficiency is not achieved at the pump. Anonymous above makes a very good point, but I believe that the researchers realize that there is no efficiency saved if making the car’s batteries burns as much energy as running a gas powered automobile. There are some amazing things beginning to emerge in energy efficiency. I anticipate amazing things in the next ten years, as long as the research isn’t killed by interests. The tesla or something like it is probably one of those innovations. I certainly hope it works.

  4. It may be time for battery technology to advance. I’ve noticed with alot of battery powered devices, such as digital cameras and windows mobile devices, it seems that even though we’re able to push the limits of nearly everything on these devices and make them do amazing things.. it seems we’re not giving enough attention to battery technology and that needs to change.
