$1/Gallon "Green Gasoline" In Sight 740
mattnyc99 writes "We've gotten excited here about the startup that claims it can make $1/gallon ethanol out of anything from trash to tires. But we've also seen how cellulosic ethanol is a better option, and how ethanol demand in general is only adding to the worldwide food crisis. So what about $1/gallon gasoline? NSF-funded researchers at UMass Amherst just completed the first direct conversion from cellulose using a new method of hydrocarbon refining, which they claim can be commercialized within 5-10 years and essentially make fuel out of anything that grows. Quoting: 'We already have the infrastructure in place to distribute liquid fuels. We're using them to power transportation vehicles today, and I think that's what we'll be using in 10 years and in 50 years,' Huber says. 'And if you want a sustainable liquid transportation fuel, biomass is the only way to go.'" The process is running at about 50% efficiency now; the $1/gallon figure is based on getting to 100%.

1 US gallon = 3.78541178 litre
Over here in Sweden the taxes put the gasoline price at something like 12.49-12.99/litre in this town right now according to a webpage.
Say 12.70 sek / litre * 3.785 = 48.07 sek.
8.36$ / gallon in the gasoline station.
So yes, people would gladly pay 2$/gallon here. In face people already pay almost 1.5 $ / litre for etanol/E85. (And we do have tax reduction / no taxes(?) on that.)

Also does this $1/gallon figure account for the energy needed to raise/cool this biomass the 1000 degrees per second? Also the cost of getting the biomass? And the cost of collecting (and probably liquifing/straining/etc this biomass. Is this $1/gallon number include current tax rates for transportation maintenance? I have a funny feeling that that might just be the cost to actually execute the refinement assuming everything else was free.

Terra Petra - burying your stable carbon biomass (Score:4, Interesting)
This is being done/worked on. It's called Terra Petra "Black Earth" and is being developed for use in biomass gasification.
Basically you gassify carbonaceous materials such as wood or other biomass. Instead of allows all the biomass to be consumed in the process, you pull a portion of the charcoal out of the gasification stream and then disc it into the earth. Charcoal, being a fairly stable version of high density carbon will remain in this state for a very long time and in a sense becomes fertilizer for the soil (over time). Charcol is a more stable form of carbon than just raw biomass which will otherwise decay into CO2 as it rots
In fact, in the amazon, this has been going on for 1000s of years and is a way to make otherwise not so great tropical soils fertile.
Gasification combined with Terra Petra has the possibility of not only being carbon neutral, but carbon negative. If you gassify existing biomass (in particular the waste wood and garden clipping stream of most municipal wastes) you start out carbon neutral. The carbon in the waste stream is already destined to either be incinerated or 'mulched' which releases the carbon as CO2 either way.
If during the process of gassifying this biomass stream, you extract a portion of the charcoal that is created, you can then sequester it in the soil. Thus becoming carbon negative to the extent you pull from your gassifier. The trade off is that you have less carbon to convert to CO for use as a producer gas.

No. Even assuming that at 50% efficiency they can produce a gallon of fuel for $2 we still need to figure in a profit for the manufacturer, transportation and a profit for the retailer. Now add in taxes at each level, regulations, polution controls, etc. Might squeek in at $4 by the time it hits the pump. Of course in five years there might be a market for a $4/gallon alternative fuel.
If you want to understand the overhead involved look at gas. When oil was selling for $15-25/barrel gas was retailing between $1 and $1.50/gallon. Oil is now selling for >$110/barrel and gas is averaging $3.50/gallon. Kinda gives you an idea how much of the gas you are pumping goes to the terrorists in the middle east and how much is being eaten up in refining, taxes, profit and misc overhead.

also of note is the simple fact that diesel engines are so much more efficient than gasoline engines. For comparable power, a diesel engine will push a small car at least twice as far as a gasoline engine. In trucks the difference is not so pronounced because of their larger aerodynamic drag... Not until you get into heavy hauling situations where you're once again fighting the sheer weight of the vehicle much more than the air resistance. Also, diesels have fewer moving parts and typically will run at least 5-10 times as many miles as gasoline engines in similar applications.

It's very, very simple. Gasoline engines are very inefficient. Non-hybrids average less than 20% tank-to-wheel efficiency. Hybrids, just over. Fuel-burning power plants, 30-50% efficiency.

As for batteries, you're just not up to date with the technology. These aren't lead-acid or nickel-cadmium batteries here. For example, my Aptera is to use lithium phosphate batteries. These last 10-20 years and are almost completely nontoxic. Their raw ingredients are things like iron, phosphoric acid (the same stuff as in soft drinks -- made from fluoroapatite, the same stuff as in well cared-for teeth, plus sulphuric acid, which is an oil industry *byproduct*), graphite, and even sugar (for the carbon binding). These aren't "in a few years" -- they're already here. They're becoming the new standard for cordless power tools, for example.

This depends largely on usage and if you have an "All Electric" or an "Electric Plug-in Hybrid" version of the Aptera. We will share these exact numbers when they become available closer to the start of Aptera production.
So your 10-20 year lifespan of the battery isn't documented on the website anywhere that I can find.
To its credit, Aptera does say its car will cost between $26,900 and $29,900. I wonder how much of that is subsidized, though. And paying $30K for a car that does 0-60 in 10 seconds, carries two passengers, and practically no cargo isn't exactly a screaming bargain. You'd be far better off buying a more conventional gas/electric hybrid like the ones currently available.
I also note on the Aptera site that the car isn't designed for cold climates. Availability is almost non-existent as well. Last, and perhaps most distressing, Aptera offers no warranty on the vehicle. Sure, they're working on something, but as of now you get nothing.

Gasoline has an energy density of ~12,000 Wh/kg In case your math-skills are down, 160/12.000 is pretty much in the 1% ballpark I mentioned.
I was talking about actual existing batteries by the way, not fantasy-ones. There are no cars available powered by fantasy-batteries. When there are, these things may change.
Furthermore, the article compares hypothethical FUTURE battery-cars with poor examples of TODAYS internal-combustion engines. For example, it quotes tank-to-wheel efficiencies at 20%, which is not even state of the art TODAY.
A perfectly normal modern diesel does 30%. More radical designs (still ones on the market TODAY) like hybrid diesels can do 45%. And there is no reason to assume that batteries will shortly more than double in performance whereas internal combustion based vehicles will make no progress whatsoever.
It is even -more- wrong in areas where heating is desireable, like 2/3rds of the year where I drive: Some of the "loss" in tank-wheels efficiency is used in heating the interior of the vehicle, defrosting windows etc.
So, in short, the article claims "equal" performance (86Kwh delivered from 350Kg of machinery), whereas the reality, if you buy best-of-breed from internal-combustion and batteries TODAY is more like, the battery-powered thingie will have 1:6th the range of the IC-one, and it'll spend twice the mass-budget to do that. Which isn't so bad. Where it gets ugly is when you add in that the IC can be completely retanked in a minute, whereas TODAYS electric vehicles need multiple hours to even do a 75% recharge. (the last few percents take even longer)
But yeah. My 2001 (not even current) Toyota does 750km, and refill in a minute. If an electric vehicle could do atleast 160km (100 miles) and recharge similarily quickly, it'd have a chance. If it could do 250km, recharge in a minute, the IC-cars would be dead.
You're right that people should take breaks when driving anyway, but the thing is, with 100 miles range, it means the thing is empty in a -single- hour of driving (okay, make that 1.5 for those of you not in germany), and with gas-stations being spread thin in some areas, there's a small margin. Signs with "last gas-station for 50miles" aren't rare where I live, so it WOULD be very impractical to need to stop at precisely timed intervals, and very often.
