Wood gas conversion of pickups

Biofuels Digest brings us the story of Wayne Keith and his wood-syngas conversion for pickups (I get the feeling he uses mostly pickups because you can use the truck bed as you “gas tank.”

I think this option has a lot going for it. The biggest barrier to cellulosic biofuels in my mind is the dispersed nature of the resource… it’s difficult to gather it op in one place to convert it efficiently into fuel. So if the conversion is done in the vehicle, the dispersed nature of (especially rural vehicles) is a much better match for the dispersed nature of the resource.

Gasification is not a good option for urban vehicles (since the resource is relatively scarce there, although much garbage works in these trucks), but it seems an elegant solution for utilizing the large volume of diverse biomass that would never be collected by commercial operations because it is both to dispersed and varied.

Investing in Biomass

I’ve recently said that the best way to invest in both Advanced Biofuels and Cellulosic Ethanol, and Biochar (aka terra preta) is to invest in Biomass. Here is one way to go about it: buying Forestry ETFs or Stocks.

Ethanol, Cellulosic Ethanol, and Advanced Biofuels

Last week, I attended the 2009 Fuel Ethanol Workshop and the Advanced Biofuels Workshop, writing two articles.  The first is a commentary on what the corn ethanol industry needs to do to rehabilitate its image, and the second looks into how the stock investor can benefit from emerging advanced biofuel, cellulosic ethanol, and
algae technologies.

Flying too Close to the PetroSun

Algae is the most promising source to produce oil in the quantities needed to displace any significant amount of petroleum. Can is Petrosun (Pink Sheets: PSUD) the company to fulfill this promise? I doubt it; follow the link to find out why.

Two Renewable Energy Penny Stocks

I asked my readers at Alternative Energy Stocks what companies they wanted to know more about, and the two most requested were a transmission and wind company (CPTC.OB), and a company looking to make oil for biodiesel from algae (PSUD.PK)

The Evidence of my Obsession with EVs

I’ve been obsessing about the best way to replace petroleum for transit fuels. Unlike venture capitalist Vinod Khosla, I think electricity will win the day over biofuels.. the cellulosic material can be put to better use.

This has lead to a series of articles over the last few months, and I thought I’d gather them all in one place, here:

1. Why Automakers may be blindsided by updtart EV makers.

2. How much are people really willing to pay for extra range?

3. How much is range worth, updated with new poll.

4. Why Cellulosic Electricity may Beat Cellulosic Ethanol

Transport Fuels and Solar Technologies: Bird’s Eye View

For my last couple AltEnergyStocks Columns, I’ve been taking a step back and looking at how we can get an understanding of the broad trends of energy technologies. Last week, I added to the Visual comparison of Electricity Generation Technologies I did last spring with a new Visual Comparison of Transport Fuels.

Following up, today I published a look at the varius solar technologies through the lens of their applications.

Before we go back to looking at trees, I hope you enjoy this look at the forest.

(and don’t miss the National Tour of Solar Homes next Saturday)
