Er.... Clinton/Pelosian Economy maybe....
The only thing Bush did wrong is not pursuing/attacking the Clinton banking/lending nightmare with the same gusto he had for the Iraq conflict. The lending nightmare that Barney Frank's said did not exist and the good Senator from Illinois vowed to defend.
For loathing party politics, you spew it well! Obama inherited the nightmare he helped bring to into existence.
We can agree, both parties need to go, this time you guys first. I am not going to help bring another Clinton nightmare back.
Er, you mean force workers into Unions to control them using a open ballot system.
Hmmmm, billions since 1969 vs trillions in his first 100 days.
Defense vs. Wealth redistribution....
Hmmm..... Me thinks people should be skeptical of your type...
Show me.....
I have seen nothing showing positive results, just hopes, dreams, and fiction.
I have yet to see even successful results with lab animals, so....
Just show me....
Sorry for sounding a bit pointed.
It seems like more and more people have an opinion to be voiced without any regard to fact.
This can be maddening at times.
It would not surprise me to see someone in a tin foil hat at a Hamvetion, We/they can be strange folk at times...:-)
That aside here are some useful links, first a RF field safety calculator: http://my.athenet.net/~multiplx/cgi-bin/rfsafety.main.cgi
Here are the Vatican&'s values to be input, 500000 Watts at.153 MHz (Don't forget the leading decimal)
For fun, input local police cars radio information for grins, 100 Watts at 156 MHz (No decimal)
Good reference stuff that can raise eyebrows.
Here is a link to a flash tutorial on skywave propagation: http://www.ae4rv.com/tn/propflash.htm
Solar cycle 24 (The present one) has been amazingly sunspot free, so the Maximum usable frequency has not been so great.
If something does not change soon, we will be seeing Global cooling...no kidding...
Enjoy!
As far as the forum moderation scoring here, it seems very subjective. Absolute dribble has seen high scoring on a regular basis
It is irritating, sorry if I took it out on you.
"It takes a lot of juice to pump a radio signal from Italy to Asia"
Says who? QRP (low power amateur radio) operators would strongly disagree with your statement. Spend some time understanding radio propagation before making statements like this one.
Your post should be mod'ed down to flame bait. Sorry, your post and supporting reference contain no factual information on a ERP (Effective radiated power) health situation.
Actually the score of '5' also shows a lack of knowledge on the part of the forum operator.
Megawatts..... Sesh....
How pious of you. I assume by your tone that you must be in the global warming alarmist camp. The article clearly states that the scientist can only find 40% of the carbon in the atmosphere that they were expecting. Add the lack of sunspots in this cycle and it seems that we are actually headed for a freeze. Are we human beings prepared for that? I genuinely feel that someone is selling global warming like a peddler selling bottled water to me while I hold a water hose in my hand.
Well, I indeed need to re-look at my calculations. But I do not expect the results to slant towards EV's as the first time I performed them, EV's where so bad allot, and I do mena allot, would have had to change.
A diesel is great if you spend a good deal of your time on the highway. Hybrids only make sense with a lot of stop and go driving, such as in a city.
The problem with this scoring mechanism is that the moderators are scoring on perceived Karma... very subjective. Thanks for pointing it out.
Many of your assumptions are just that. The Turbo Diesel Hybrid uses regenerative braking as well.
It matters not if many people perform the same math to achieve a incorrect answer, the answer is still incorrect. I have attacked the personal transportation problem looking for an answer, and the EV just did not measure up.
Problem number one for EV's are the batteries. They are VERY heavy, their energy density is horrible compared to a stored liquid fuel, they are expensive and have very limited life times.
Problem number two for the EV is the generation and distribution of electricity. While I appreciate your table of electricity generated in California, a more relevant table would have included consumption. It is my understanding that California imports most of its electricity. If so this would make the table irrelevant. It is my understanding that nationally, in the United States, 80% of the electricity generated is done so using coal.
I am not married to the internal combustion engine, figuratively speaking. The turbo diesel just happens to be the most efficient method of mobile power generation at this time (well a jet turbine engine is more efficient, but it has issues). Fuel cells look very promising, but have a way to go (the lack of available economical catalysts, etc..).
The advances in aerodynamics, drive train efficiencies, and power conservation in EV's are impressive. If we would apply them to a Turbo Diesel Hybrid, we would have a product ready for the masses that would solve the majority of the problems with personal transportation.
A coal (read carbon) burning plant emits three(3) times the amount of CO2 as a gas one (read hydrocarbons).
At 90% efficiency for the electric motor, you loss 10%. Add another 10% loss in the battery charge/discharge (not bad really). 28% average transmission loss for grid distribution. Wow you have already lost almost 50%, lets hope generation is better.
A typical coal power plant is a little over 40% efficient. But it belches out 3 times the amount of CO2.
Can we get a refund from whoever did this DOE study?
I am interested in in information you might have on this. I have seen the Buss's presently in operation and have three concerns.
Weight (in comparison to batteries)
Gas compression inefficiencies (Heat generation at compression)
Safety. Oil at a couple thousand PSI scares me in a crash situation.
Of course you are citing the new designs and not the normal average plant that exists tody.
Your reference also cites that a coal powered plant emits three(3) times the amount of CO2 that a nice hydrocarbon (natural gas) one does. My premise still stands.
Interesting that I scored a 1 but the ineffective rebuttals are scoring 2. So much for science.
The problem then would become higher operating costs, a total lack of infrastructure (think existing rolling blackouts without adding the new load), and more CO2 emissions (burning coal vs a hydrocarbon).
Thanks for the link. It certainly helps my argument after you un-spin the converstaion and use thier own data. I noticed they convenently left out power transmission losses in the tabled data, though they mention it in previous paragraphs.
Additionally, chemistry still calls for the generation of electricity using carbon only (read coal) to emit more CO2 than using a hydrocarbon, such as gasoline or diesel. It matters not how much you clean the fuel before use.
I will go head to head, EV vs Turbo Diesel Hybrid and win in any category; emissions, efficiency, pollution (Recycling batteries), costs of operation.
I understand the efficiencies with a electric motor can be substantial. But the math does not add up.
A battery will delever up to 90% of the energy put into charging it. A electric motor can be up to 90% effecient as well so we are at 80%. Cool.
Now the grid will loose anywhere from 20% to 50% in distribution. Just for conversation lets call it a 35% average loss. So we are at about 55% energy lost so far.
Now a coal or gas power plant has a 40% maximum efficiency. Since most of the electricity generated in the US is via coal, you just added a double wammy because you are not burning a nice hydrocarbon anymore, you are just burning carbon.
So now that your electric car is a 20% to 25% efficient contributing to CO2 emissions more than a standard hydrocarbon burn, what state is pushing for this technology... California???? The state of rolling black outs?

Hello Moryath,
It sounds like you know what you are doing but here are some idea's on how to resolve your DTV reception issues.
Sounds like you are close in.
Get rid of the antenna preamp. Most have a horrible S/N ratio and just add to the problem with receiver front-end overloading.
Switch to a more onmi directional antenna. This would help with the multi path issue.
Forget the sales hype. DTV is in the same band space as conventional TV. The same antenna's work. The lowest channels frequencies are lower than conventional FM broadcasts. (Ch2-6 55.25-83.25Mhz)
Twin lead has considerably less loss than coax, use it for your down feed, twisting it every so often. Put a balun (4:1 300 to 75ohm) at the bottom.
Wow, I'm a troll. I really do not understand how that happened. I genuinely am hoping that real scientific facts enter into this country where popular trends now lead the day.
It seems obvious to me now that Mr. Chu is going to have his hands full (Now that was a sarcastic troll).
After actually trying to address high energy prices, the only real answers I found turned out to be a hybrid turbo diesel powered vehicle and geothermal heating/cooling. The rest was a bunch of huwe and hopeful thinking.
"but I'm hopeful that a scientist will base policy on evidence"
Me too!
The planet has cooled almost 3 tenths of a degree since Mr. Algore's assertion that the plant is getting hot.
I am all about being a good steward of the planet. I question the logic of allot of the radical answers to almost insignificant issues, all the while making the problem worse.
As an example: Lets switch vehicles from burning "hydro"carbons with a maximum efficiency of 30 to 40 percent to electricity. Electricity, here where we generate most of it with carbons at a max efficiency of 40 percent and can lose almost half of that in transmission. Add another 10 percent loss in battery storage and another 10 percent in conversion back to kinetic energy.
Silly.
How about make the vehicle more efficient... period.
Where is my Turbo Diesel Hybrid!
When mobile phones where first introduced, the Insurance industry noticed that the owners had better than average driving records and adjusted their rate accordingly. This was possibly due to the fact that such mobile service was very expensive at the time.
Natural selection via Capitalism....
Now we are attempting to regulate the service because more inept users have access to the convenience.
I find the trend to regulate the intelligent because of the inept alarming.
Let the pseudo science begin.
Deposed two dictatorships, disarmed one nuclear nation (working on number two), saw Syria out of Lebanon, and joined a nation against a new foreign power.
Yeah..... Horrible...
Should have bombed a aspirin factory, a Yugo plant, and had foreign commanders set it up so that our troops corpse dragged through the streets.
Now that diplomacy!
Meanwhile in the news, officials from both Venezuela and Cuba indicated they are seeking Chinese firewall and human rights technology. Not to be undone, the Obama campaign has offered propaganda technology that calls for change.
