Money Mess - Background Information
The payoff for delinquent mortgages in the US is between $60 and $100 trillion. Pay this off and a lot of the crisis goes away.
One big problem is that the derivatives total up to about $80 trillion. The US GNP is about $14 trillion. A lot of those bad loans are wrapped up in that $80 trillion derivative packages.
The reason we got into this mess is that back in the late 70s, the federal government initiated the Community Reinvestment Act (check it out on Wikipedia) which penalized lending banks for not giving loans to low income borrowers. Many of the mortgages applications were filled out with false information (i.e., income, job status, etc.) The mortgage people made the commissions and then sold the mortgages which got repackaged and sold as securities. A lot of those securities are owned by investors (and banks) in other countries (i.e., China)
This was all legal and stupid. What a mess. Giving out money for votes. Our Congress is the main culprit. The voters need to make some adjustments.
Just my two cents worth.

Tennessee Shines
This was show #2. This is a live radio broadcast on the last Wednesday night of each month. It is videotaped in HD for a later broadcast on WBIR-TV. I also attended the initial performance last month.
I recommend that you check it out. You can listen via the internet.

49 Oil Platforms Destroyed by Ike
This country needs a significant source of alternative fuels now. If nothing else, it gives a diversification of fuel sources, not to mention jobs and the ability to keep our money at home.
More drilling may help in the short term, but it only buys us time to develop electric vehicle technology and an efficient alternative fuel infrastructure.

Feds Bail Out AIG For Only $85 Billion
I guess this is what happens when corporations purchase a sufficient number of Congressional seats in the Legislative Branch of our government.
My prediction is that as the economy continues to implode, this methodology will continue until the distinction of the federal government and private corporations becomes seamless.
Our freedoms are in grave danger.

Hydrogen Fuel Boost In Gasoline Burning Vehicles
Dear Cecil:
An auto mechanic friend claims to have a gizmo that makes his vehicles run at least partially on water. He swears it's true and has about five test vehicles running with this thing now. It will work best on vehicles with carburetors — fuel-injected vehicles need tweaking of the computer chips. He's got one on an old VW Bug and says he gets about 80 MPG — he's trying to win a prize for getting over 100 MPG. He installed one in a large diesel truck that originally got about 8 MPG; it supposedly now gets 20 to 22 MPG with lots more power. My friend says the gizmo uses electricity from the alternator to split water molecules into something called "Brown's gas" that gets input into the intake manifold. Is this true or another myth?
— Walt Bruun, Glen Ellyn, Illinois
Cecil replies:
I'll tell you one scientific reaction involving Brown's gas you can take to the bank: it makes my blood boil. The device you're talking about places the emphasis on hydrogen, thus piggybacking on the "hydrogen economy" meme President Bush brought to public attention in his 2003 State of the Union address. Newspapers and magazines subsequently devoted acres of unskeptical column space to on-board hydrogen-generation and -injection technology. In 2005, for example, Wired wrote that big-rig truckers were getting major improvements in fuel economy and power from hydrogen electrolysis systems.
Here's what happens. The gizmo is hooked up to a standard internal combustion engine. Like your pal says, it draws power from the car's electrical system to split water into a mixture of hydrogen and oxygen — so-called Brown's gas — which gets fed into the engine and burned along with the usual gasoline/air mix. Alleged result: big gas savings!
But how? On the most basic level, the technology makes no sense. Let's walk through the process:
1. Your car engine burns gasoline or diesel fuel to power the wheels and your alternator (among other things) at about 20 to 25 percent efficiency.
2. Your alternator generates electricity at about 60 percent efficiency.
3. You take said electricity and use it to turn water into hydrogen and oxygen at about 70 percent efficiency, tops.
4. Then you burn the hydrogen and oxygen, or just the hydrogen, in your engine at about 98 percent efficiency.
In short, you're converting fuel A, gasoline, into fuel B, hydrogen, which then helps power the car. Net efficiency of this complicated process: 10 percent. Efficiency of an ordinary car engine (see step 1 above): 20 to 25 percent. Conclusion: Hydrogen gizmos are a fool's bargain.
Advocates claim using hydrogen as a fuel increases combustion efficiency. Problem is, in modern engines combustion efficiency is already close to the max — 95 to 98 percent under optimal conditions in a gasoline engine, 98 percent or better in a diesel engine. Understand, this refers strictly to how thoroughly the fuel burns in the cylinders. Overall engine efficiency is, as seen, much lower, due to heat loss through the engine block and out the tailpipe. Switching fuels won't change that.
So why do hydrogen injector users report improvements? The same reasons people often swear by iffy technology — lack of appropriate comparisons, sloppy record keeping, wishful thinking, a sample size of one. The fact that fuel economy is partly a function of driving habits no doubt also plays a role. If you simply pay more attention to your speed when driving, you can often increase mileage even without a miracle device.
To be sure, a little water can improve internal combustion engine performance under some circumstances. Water injection helped WWII aircraft engines put out more power by reducing knock. BMW has been trying to increase fuel economy and power by using exhaust heat to power what's in effect a small steam engine attached to an internal combustion engine. A Honda hybrid uses a similar concept to turn a generator to recharge the battery packs while cruising. Although some bugs remain to be worked out, a six-stroke engine using water injection for power and cooling shows promise. Bear in mind, though, that water isn't being used as a fuel in any of these cases. If you really want to improve your fuel efficiency, check your tire pressure. Sexy? No. But it does have the advantage that it works.

Staying Alive - The Status of Nuclear and Radiochemistry
If we don't lead the world in this technology, we darn sure better be leading in area of alternative energy development or we will go down as footnote in world history. Not much can be done in this world without a sustainable source of energy.
