    Economics of Bio Fuel

    YouTube

    Interesting video. Part of it looks at the link between food prices and oil prices, the direct link that exists today, when oil goes up food goes up, was not there before we started using food as fuel.

    Makes sense it is more economic to use food as fuel when oil is expensive.

    Re: Economics of Bio Fuel

    The oil companies are experimenting with algae as fuel.

    What could go wrong?

    If they get something that will not use agricultrual land to make fuel I'm all for it.

    The problem is that the increase in food prices is killing the world's poor in the tens of millions.

    3 Billion people live on less than $2.50 a day. The food price is twice what it would be if we stopped doing this evil.

    It's not just fuel companies. The problem with algae so far is the ability to do it in a manner that could even remotely keep up with demand. We have a local government-funded facility that, among other things, does a fair amount with bio-fuel research. Last time I saw any of them being interviewed, they were saying that algae and switchgrass were the most promising but they still had a very long way to go before they were viable.

    Would they be harvesting it from the ocean?
    The left says the right is full of racists and bigots and have no tolerance. Nobody from the right organizes interference with gay pride parades, or other leftist events. The left however always has a group interfering with events organized by the right. Who are the tolerant ones I ask? Most certainly not the left.

    Algae and switchgrass, are effectively collecting solar energy at very low density, and converting a very small amount of that energy to a recoverable hydrocarbon.
    I think the more direct approach of simply making hydrocarbons from scratch is a more sustainable path.

    Solar and wind energy at high density will create a problem for electrical grids, the current oil refineries have large scale grid connections
    for co generation, so could harvest the massive energy surpluses and store those surpluses as carbon neutral transport fuels.
    Current jets could fly across the ocean without any new CO2 emissions, (the fuel having been made with CO2 harvested from the environment).
    Gasoline cars could fill up with carbon neutral gasoline, and so on.
    As the process gets more efficient, the price where this technology becomes viable get closer.

    Electric cars crash

    Posted on 01 Dec 19 by TONY THOMAS 1 Comment
    Globally, SUVs are swamping car sales and here’s the point: as fast as governments bribe or wrangle people into low-emission electrics, the popular shift to SUVs more than cancels the emissions cuts. In the forced march of folly towards net zero emissions, electrics are as much a lost cause as windmills. Tony Thomas 30 November … Continue reading

    I have a couple of questions for you, Tim... of that $2.50 a day how much of that is actually being spent on food? And do you know how much a serving of corn costs? Or a serving of sugar costs?

    Re: Economics of Bio Fuel

    We use about 1/3 of our corn production for fuel. That means growing high sugar corn, also known as sweet corn. Now pretty much ALL corn grown is high sugar. Why that matters is modern corn has almost NO nutritional value. Traditional corn had good sized protein kernel but high sugar corn has a very small, insignificant protein kernel. Additionally, high sugar corn does not pick up nutrients and minerals from the soil like traditional corn did. And since our soils (world wide) are depleted now that makes the problem even worse. Corn is now an empty calorie. About all it does is promote diabetes.

    BTW; modern bio-engineered crops of all types grow faster and bigger and are more pest resistant, but do not take up nutrients very well. Dumping large amounts of nitrogen on them increases the yield (top growth) even further, but does nothing to improve the depleted soil.

    In many poverty stricken nations (much of Africa and S. America) the land that could be used for domestic consumption crops is being used to grow export crops to pay back loans. In other countries population has exceeded the ability of that nation to feed itself. That is the case in Egypt, for instance. And importing caused huge increases in prices, because transport and processing imported bulk food is expensive. Which led to the "Arab Spring".
