100mpg Hummer H3 by a Provo Utah Company

Thursday, April 23rd, 2009

Raser Technologies, based in Provo, UT,  is a company I’ve been keeping my eye on for a couple years. They caught my attention because they have been working on some uber-cool technologies that have huge potential. They have held my attention because they are so close to where I grew up. A couple of my family members even bought a few shares of Rasor stock (RZ).

Until last week the company was not very well known. That all changed this week when they debuted a 100mpg Hummer H3. It is a 700 volt electric vehicle with a 4 cylinder gasoline engine that acts as a “range extender.” The gas engine has no mechanical connection to the wheels. All it does is turn a generator that charges the batteries, powers the electric motor, or even provides power for off-vehicle electric devices (should be nice for construction workers).

Check it out:

I love cutting edge technology. Stuff like this is paving the way for a whole new generation of automobiles. I do however, have to throw in a warning. Don’t expect to be able to afford one of these, at least not for a few years. This Hummer has 3 large (and expensive) lithium ion battery packs. Even if the Raser components (motor, generator, and controller) can be cost effective when mass produced, the batteries are not—at least not yet. Mobile devices (mostly cell phones) have pushed battery technology to a point never before seen, but it still has further to go. I wonder how far away we are from having vehicles like this in our driveways. 3 years? Maybe 5? Maybe more? I’m excited to see.

Michelin Reinvented the Wheel

Thursday, February 5th, 2009

Imagine a car where the motor, transmission, drivelines exhaust, suspension, and brakes are all inside the wheels. Okay, that’s impossible. But what if there were no need for a transmission, drivelines, and exhaust? Could you put the motor and the suspension inside the wheel? Michelin did:

The entire unit bolts to the car and needs nothing but a brake line and electric connector to enable all its components.

This invention has HUGE potential! It could be used on EVs, Hydrogen Fuel Cell vehicles, or even hybrids (at least a Chevy Volt type hybrid). It could be used in two or four-wheel-drive, and front or rear-wheel-drive configurations. Car designs could change drastically because the usual space set aside for drive train components could be used for other things.

Here is one prototype application (notice how the computer controlled suspension allows it to lean into turns):

The first production car to use the technology will be the 2010 Heuliez WILL.

I wonder if changing a tire will still be simple. If not, I suppose there is always AAA to do it for you. :)

High End Luxury Small and Green Cars

Tuesday, October 14th, 2008

There is a gaping hole in the automotive industry’s lineup of cars. I first noticed it when movie stars started driving the first generation Prius and Insight. The ultra-rich settled for cheap, poor driving cars to show their commitment to green.

Meanwhile, there seems to be a mind-set in the automotive industry that small, green cars have to be cheap. I’ve been wondering for a long time why Lexus, Acura, Infinity, Cadillac, Lincoln, and the others don’t have small, high-mpg vehicles loaded with expensive, organic/recycled materials.

It looks like ToMoCo might be the first mover. Lexus will have its own version of the next generation Prius. I expect it to be extremely successful and profitable. The others will follow suit.

Gas Prices, Cars, Trucks, and Hybrids

Wednesday, April 16th, 2008

I just finished my term project for my environmental economics class. I started out looking for a relationship between recent gas prices and hybrid sales. What I found was interesting. Check out the graphs below (click on them for a clearer picture).

Nominal Gas Prices (1990-2007)

You see that gas prices have a lot of seasonal fluctuation. I was only interested in the overall trend, so I applied what we call a “weighted moving average smoother” to the data–basically it just takes out the “noise” and leaves the overall trend (I used this smoother on all the graphs below). Here is what is looks Like:

Smooth Nominal Gas Prices (1990-2007)

Because nominal prices tell us nothing about the real cost of gas (doesn’t account for the changing value of the dollar or the level of wealth we enjoy), I also collected GDP data:

Nominal GDP (1990-2007)

Using nominal gas price and GDP data, I created a relative gas price (gas price/GDP). It is interpreted as the cost of gas relative to our level of wealth:

Relative Gas Prices (1990-2007)

Notice the relative cost of gas was falling all through the 1990s and for the most part increasing throughout the current decade. Now look at the ratio between car and truck sales in the U.S. during the same time period:

Ratio: Car to Truck sales in the U.S. (1990-2007)

In 1990 there were about two cars sold for every truck. That ratio continuously fell until it finally bottomed out in late 2004 when there were more trucks being sold than cars (relative gas prices had already been increasing for 2-5 years).

Now look at the number of hybrids sold as a percentage of total vehicle sales:

Hybrid sales as a percentage of total U.S. automotive sales

Notice that hybrids took a sharp turn around the same time the car-truck trend switched directions.

My data does not allow me to control for consumer tastes and preferences or countless other factors that contribute to these trends. That aside, it appears that consumers react to shifts in relative gas price trends with about a 2-5 year lag (at least in terms of the type of vehicles we purchase).

In hind sight, I wish I had collected data for a larger time period. It would be helpful to see other shifts in relative gas prices (think 1970’s gas crisis). Did consumers react similarly? Was the lag in their reaction similar?

I collected GDP and U.S. automotive sales data from the Bureau of Economic Analysis. Gas price data came from the Energy Information Administration. And hybrid sales data came from Green Car Congress.
