    No, the *energy* to weight ratio of batteries sucks. The *power* to weight ratio of modern automotive li-ions is incredible. AltairNano's can deliver as much as 4-5kW/kg. If you have something like the LightningCar with a range of 180 miles, and let's assume 200Wh/mi, that's 36kWh, divide by 90Wh/kg, that's 400kg, so about 1.8MW of power = 2,400 horsepower. The batteries aren't the limiting factor; the motor is (and electric motors are pretty light). Even if you assume 100kg, the weight of a typical non-sports-car ICE drivetrain, that's around 600 horsepower. And factor in that ICEs only deliver a fraction of their horsepower at most RPMs/torque requirements, while electric motors are at full power across most of the curve, so you really need to significantly increase those electric numbers.

    Even with their low state of maturity, EVs are already challenging gasoline records. The eight-wheeled Eliica is trying to beat gasoline speed records, while Wrightspeed is convinced that the production version of their 0-60 in 2.5 second X1, known as the SR-71, will be able to beat a Veyron at 0-60.

    As for energy to weight, comparing the raw energy in batteries to the raw energy in gasoline, and yeah, you'll come to the conclusion that they're atrocious. However, there are a few things to note. 1) Gasoline engines only get a small (~20%) fraction of the energy of the fuel out as torque; EVs get ~80-90% of the energy in their batteries out as torque. 2) Gas tanks are light, but internal combustion engines are heavy. Electric motors are light but batteries are heavy. The paradigms are reversed; batteries aren't competing against a gas tank for weight and space, but against the *engine*. Currently, for a vehicle of range comparable to that of your typical gasoline vehicle, yes, batteries lose -- however, not by a margin of nearly 100:1 as it may appear just by comparing energy densities, but only by a margin of about 3:1. And, quite honestly, some next-gen batteries may be able to give a three-fold or greater increase in energy density (silicon nanowires, silicon nanoparticles, tin nanoparticles, etc for the anode, and things like nanoscale-layered or fluorinated metal oxides for the cathode).

    Exactly. You need to have a kilowatt hour or two of reserve charge to "average out" the hills. Optimally, your motor should be sized to haul you up an interstate at 5-6% grade (6% = legal max) at what you consider a reasonable speed, while your engine should be sized to manage a 1-2% grade (you generally won't surpass that as a running average of slopes on an interstate). Smaller mountain roads may be steeper and have higher average grades, but you won't be climbing them at nearly as high of a speed, either.

    Not exactly. Exercise increases the rate of burning calories (that's why people who want to lose weight do it). The human body is inefficient about turning food calories into kinetic energy, and plants are inefficient at turning sunlight into calories (photosynthesis is fairly efficient, but most of the energy doesn't end up stored in a way we can recover through digestion -- usually somewhere between a fraction of one percent and a few percent is). And there's all of the energy involved in growing, harvesting, processing, and transporting that food, which is often greater than the energy contained in the food.

    Lastly, there's a value to time. The person could instead, for example, be building wind turbines or installing solar arrays. The biggest reason why this is a kit car is almost certainly because the maker didn't want to have to work out a cost-effective mass production system, not because it's somehow better for the environment that way.

    Not *having* to meet safety standards != Not meeting safety standards. There are about a dozen advantages to the tadpole trike design -- reduced wind resistance, lighter weight, lower construction cost, lower maintenance, drivetrain simplicity, and so on. Honestly, I'd love it if we:

    A) Ditched our classification system based on the number of wheels
    B) Came up with a set of environmental and safety classifications that vehicles could voluntarily choose to try to qualify for
    C) Required that their environmental and safety classifications be prominently listed on vehicles for sale
    D) Banned vehicles that don't meet given requirements from different kinds of operation -- for example, perhaps to drive on a public road at all, you must meet at least "silver" environmental standards, and to drive on a highway, you must meet at least "bronze" safety standards, while for a child to ride in a vehicle on any public road, it has to have at least a "silver" safety rating. Something to that nature.

    I don't see why those who want to innovate should be penalized for doing so. All that should matter is the net results: how safe it is and how clean it is.

However, it's hardly the only such vehicle that's coming out in the next couple years; there are dozens. If, for some reason, Aptera weren't to work out, I'd probably go with a Mitsubishi i-MiEV.

    What insight. Why didn't I realize that? Palin is more qualified than Obama! Let's just run down the timeline here:

    When Obama was graduating from Columbia University (Ivy League) with a degree in Political Science with a focus in International Relations, Palin was graduating high school and competing in beauty contests.
    When Obama was President of Harvard Law Review, then organizing Chicago's largest voter drive in history and teaching Constitutional Law, Palin was switching between six low-key colleges before finally getting a degree in journalism (polisci minor)
    When Obama was in the state senate drafting over 800 bills (so many that he created a backlog; there's still some working their way through today), Palin was being elected of a tiny town of 5,000 (at the time) with 53 employees that she didn't even control (a city administrator did that) with just over 600 votes. Pushed for policies that drove the town into $22 million dollars of debt -- and that *with* the massive sales tax increase (spending increased ~34% during her tenure) and over $20 million in federal earmarks. $1.5 million of the debt due to bungling an attempt at eminent domain to build a sports complex.
    Obama was elected to the senate from one of the US's largest states with 3.5 million votes, where he has served for twice as long as Palin has been governor (elected with 114,000 votes, to run a state with about as many people as Fort Worth, Texas). Obama served on 13 committees, including the prestigious Foreign Relations Committee, and has met world leaders in dozens of countries across Africa, Europe, and the Middle East. Palin got her first passport in 2007, and her campaign claims the following foreign policy experience: Canada, Kuwait, Germany, Ireland, and Russia. Canada because she's crossed the border before. Kuwait because she flew there to visit the Alaska National Guard (never left the base). Germany because she stopped at a base there on the way back (never left the base). Ireland because her plane stopped there to refuel (never left the airport). Russia because "Alaska is close to Russia".
    Hmm... since Obama's senate term (involving sponsoring over 500 bills and drafting over 100, including the most sweeping piece of ethics reform since Watergate) is twice as long, that's probably not a fair comparison. I guess we should merely compare his *presidential campaign*, which is about as long as her governorship. 1.5 million donors versus ~680,000 taxpayers. ~80,000 campaign volunteers versus ~50,000 state employees.

    You're right -- Palin is clearly more experienced!

    The thing is that before we paid much attention to this stuff, there was ONE real model that predicted a global temperature increase: global warming. It was not ignored before because "the man" was trying to hide science, it was ignored because there was NO effort to show an actual cause and effect relationship.

    Spoken like a person who's never read a paper on the subject. The study of climate change is part models and part real-world data gathering and testing. Even among models alone, there are *many different* models, most on particular aspects of climate forcing and impacts, not the more famous global models. There is not one "model". And it wasn't ignored, by any standard; it's been an active ongoing research topic in the scientific community for decades. Peer review is the judge, not public opinion.

    This becomes embarressing when things like the carbon retention of the Sahara are studied, as we discussed weaks ago, and suddenly billions of tons of carbon disappear from the air in our models, but the temperature hasn't changed at all.

    Waht arr yoo talkng abowt?

    The reason this worries me is that, while fighting pollution and emissions is never a bad thing, we could very well be ignoring the elephant in the room, simply because the global warming discussion has become so political, (and that's the activists faults, not the scientists). What if, although our carbon certainly doesn't help, most of this is due to cyclical sun output?

    No. Read section 2.7, which summarizes pretty much every peer-reviewed paper published on the subject. Not even close. I mean, seriously -- did it never occur to you that maybe, just maybe, we have observatories and satellites studying in detail essentially every thing the sun does, in addition to all kinds of long-term proxy data?

    Ice ages happen regularly, on the order of tens of thousands to hundreds of thousands of years, along the lines of Milankovitch cycles. The Isthmus of Panama formed once, three million years ago.

But just the minimum amount of power that you need for a reasonable car is way, way too expensive with fuel cells. If your goal was to make a vehicle that can drive from Scotland to Vladivastok on a single tank, then yes, hydrogen would be a better choice. But for real-world driving demands, it's not even a close comparison, financially. Or safety-wise. Or efficiency-wise. Or operations-cost-wise. And so on.
