Usually when you argue with liberals, you can start winning right off the bat by denying the premise of their argument. On energy, their premise is that wind power is pure, clean energy, harnessing mother nature with no downside at all. After all it is just a breeze, which we like on hot summer days, and other than lifting loosely glued toupees and bad comb-overs, it is harmless. Right?
Well we don't get wind power from pin-wheels. We get it from thousands of huge, industrial grade wind turbines, which, for the dim bulbs on the left, are machines.
(Excerpt) Read more at patriotroom.com ...
“There are several projects already producing over 100 MW across the globe. “
There is over 5,000MW of installed wind power in Texas, we are #1 in the nation in wind power.
It still begs the question - how much should we subsidize wind? Any ‘good’ thing gets ruined by subsidies.
I dont want to quibble, I was making a point that all real technology can be cast in negative terms, but ...
“PV is SILCON mostly, with Aluminum and Boron dopants- all NON toxic chemicals, along with glass and aluminum”
I am in the semiconductor industry and I can assure you there are multiple toxic chemicals used in manufacture of semiconductors including PVs.
General agreement on what needs to happen ...
(1) DRILL DRILL DRILL our own resources
- AND USE SHALE
(2) BUILD NUKES NOW at least 100 new plants
- MAKE IT 400. STOP NAT GAS FOR POWER.
(3) switch to hythane (hydrogen - natural gas)combustion / electric hybrid vehicles over the next 25 years
- PLUG-IN ELECTRIC HYBRIDS + ALT FUELS = DRAMATIC REDUCTION IN OIL CONSUMPTION
(4) start to convert to liquid H2 for airplanes
- NOT NEEDED IMHO, LIQUID ALT FUELS WORKS
(5) incentivize PV with a SREC program like New Jersey , where you get ca$h for your clean energy, that the utilities must purchase to do business in the state
- WE HAVE BILLIONS IN R&D ALREADY. CONTINUE.
- ADD BACK NUCLEAR POWER R&D IN LEAD_COOLED REACTORS.
(6) put wind in where it makes sense and improve transmission lines to support the sparse areas
- WHERE IT MAKES SENSE = DONT SUBSIDIZE IT
(7) increase energy efficiency and power quality - without FORCING ANYONE TO switch to those stupid CFs
- AGREE
(8) persue ANY other energy technology that makes sense
(9) ELIMINATE EtOH and other STUPID programs
- Ethanol subsidies + ethanol tariffs = bizarroworld
- Eliminate subsidies

hydrogen is very SIMPLE
I can put a BOX in your house and plug it in, plug it into your car, and you can run your car
hydrogen very clearly works
and please name for me the fuel with the HIGHEST ENERGY DENSITY __________________________
name me the fuel that propels the space shuttle________
name for me some other “alternative” or renewable fuel (ie on the scale that we currently use JP4) with enough ENERGY DESNITY (kJ/ kG) to power JET AIRCRAFT
I am awaiting your answers
_____________________
You’ll get my answer, as soon as you tell me where on earth there is any free hydrogen.
WIND POWER will cause massive climate change.
For every windmill there is an energy trade off. Instead of the wind blowing freely and helping to move the clouds and moisture, the wind energy gets intercepted by the blades.
The wind energy is TAKEN from the environment and converted to electricty. This is not right, since energy can neither be created nor destroyed, the wind energy that is now turning turbines is not available to blow freely in the environment.
Taking the wind away by using windmills means there will be less wind downwind from the stations, so if Texas has a lot of windmills making electricity then Louisiana and Missississippi will not be getting as much wind in their environments.
This will lead to more pollution in the down wind areas!
Less wind means fewer clouds and less rain!
We cannot take the wind from some people just to make electricity, it’s going to ruin the climate!
If there are too many windmills then all the wind will be lost because all of the wind will be turning turbines and no more wind will be free to just blow!!
FREE THE WIND Let it blow!

hydrogen can be obtianed from water and electricity in any home
h2 can be produced from natural gas via reformation
nothing is “free” except primary sources of energy
gasoline is certainly not free, is it?
its all as matter of economics
If I can put in box in my house and make my own gas for less than 4$ / MMBTU equiv , then the game is on
If I already have electricity, what am I using the hydrogen to do electrolysis for? Anyway, H2 in H2O is not free hydrogen.
h2 can be produced from natural gas via reformation
That's also not free hydrogen.
nothing is free except primary sources of energy
This statement is nonsense.
Hydrogen on earth is not free in the sense that it is already bound to other things, most notably oxygen, but also carbon, and metals. If you must reduce the hydrogen from water, in order to oxidize it in a fuel cell, or combustion, there is a net loss of energy. Oxidizing hydrides in metals has enormous energy costs. Oxidizing hydrogen from water and then burning it in the atmosphere or using it in a hydrogen fuel cell has a theoretical net zero energy yield, but of course because of entropy is a net energy loser in practical applications. Oxidizing hydrogen from hydrocarbons has a net positive energy yield.
gasoline is certainly not free, is it?
Good Lord. This statement is ridiculous. Gasoline is a refined product which has a net positive energy yield. Hydrogen has a net negative energy yield when reduced by electrolysis or recombined into H2 from hydrocarbons. It is NOT a source of energy. It can be used to transport energy, but it CANNOT be used to produce it, and as a transport medium, it SUCKS.
Since you've obviously no knowledge of Physics or even rudimentary Chemistry I hate to pick on you, and you've made at least a mild attempt to answer my question, though you appear to be confused on the distinction between chemically bound states of oxidized elements (free states) and economics "having no cost," which is a unicorn; there is no such thing. I'll try to enlighten you as to your earlier questions.
As for your hydrogen house, please don't move in anywhere near me.
Is it up in the hills or mountains? On our ranch, which is mostly mountainous there are places where the wind blows 24/7. My MIL lives up on the slope and the wind blows almost constantly there too while there isn’t a wisp of breeze down in the valley.
“Since you’ve obviously no knowledge of Physics or even rudimentary Chemistry I hate to pick on you”
Oh really, my friend?
Umm
Actually I have advanaced degrees MSME and MS ChE in both Chemical and Mechanical Engineering , with theses based on supercritical flow reactors and catalysis
so let me pick apart your answers and lets see whose right
AGAIN , the key here is finding ALTERNATIVE FUELS
WE CANNOT CONTINUE TO DEPEND ON THE SAUDIS AND CHAVEZ, CAN WE? and OIL will not last forever will it? I think gasoline is great - dont get me wrong - but it is problematic now with demand and supply issues
This is factual
nothing is free except primary sources of energy
you say its nonsense
well youre wrong
primary sources of energy include anything that takes no initial input to derive- this includes solar, wind, Oil, Uranium ,Coal, Natural Gas and many others
gasoline is certainly not free, is it?
Good Lord. This statement is ridiculous.
Oh really? its 4$ PER GALLON RIGHT NOW- that aint free!
and its like 8-10 $ in Europe
forget the kBTU / gal etc, it COSTS MONEY
“It can be used to transport energy, but it CANNOT be used to produce it, and as a transport medium, it SUCKS.”
Oh really ? what do we use to power the space shuttle ? what is the ONLY fuel with enough MJ/ kG to even make it into space ? huh ? HYDROGEN - Liquid
you said : Hydrogen does NOT have the highest energy density of any substance
youre DEAD WRONG , and it shows you are cockier that you should be and acting like the haughty John Kerry
your statement “ In combustion, even compressed or liquefied hydrogen has an energy density far below gasoline” is DEAD WRONG
lets look at the FACTS
FROM http://en.wikipedia.org/wiki/Energy_density
energy density (MJ/ kG)
hydrogen 143
gasoline 46.9
rest of propane, butane JP-4 etc 40-45
so youre WRONG. PERIOD
Hydrogen is by FAR the highest energy density fuel by mass
now by VOLUME, your litany of complaints about hydrogen are closer but you still need a spanking by a REAL CHEM E
Here are your false statements
“Hydrogen is extremely dangerous to store and transport in most forms.”
this is total nonsense- hydrogen is completely nontoxic and dissipates instantly ,and generates only steam
gasoline and JP4 are FAR more dangerous and toxic, not only on their own merits (water pollution and air pollution) but also when there is an accident , they pool and burn for hours , giving off noxious gases - see the recent plane wrecks and the one in Tenerife in 1977
look at the Hindenberg- the typical example posed by those who think H2 is dangerous - most people walked away without a scratch and the flames were over in about 5 minutes
“The material with the highest energy density currently available to our science is uranium. “
gee thats great - lets runs cars and planes on U238 !
“Because hydrogen is an oxidizer, it destroys metals with which it interacts, “
This is called embrittlement- it is an issue but not a major problem - you far overstate it
the BOTTOM LINE is that I can produce hydrogen in my house and run my car on it for about 5$ / gal equivalent - with no pollution or gasoline
I can mix in to ANY fuel stream and improve the burn
I can mix H2 with CH4 (nat gas) at ANY stoichiometric ratio
T Boone is right - we DO need to use nat gas for cars and then begin producing H2 with off peak nuclear energy and supplement - its called HYTHANE
you can live in the past with you misconceptions and half truths, but even John McCain gets it and is talking about it
hydrogen can run cars, planes , the space shuttle and pretty much anything else - and can be made from water
that is the facts , please feel free to refute
Your reply continues to confuse "economic cost" with "already oxidized." Until you get your head around the difference, my PhD in physics trumps your alleged "masters degrees" in engineering.
No source of energy is free in any economic sense; primary or otherwise, but that isn't the point. All of the practically available hydrogen on earth is already oxidized. Therefore, it is not a source of energy in the same sense that hydrocarbon fuels are.
Get it?
Oh really ? what do we use to power the space shuttle ? what is the ONLY fuel with enough MJ/ kG to even make it into space ? huh ? HYDROGEN - Liquid
Had you read my post, instead of responding to nothingness, you would have seen my criticism of liquid and compressed hydrogen. The liquid hydrogen used in the space shuttle takes orders of magnitude more energy to produce than it provides.
FROM http://en.wikipedia.org/wiki/Energy_density
No one with an advanced degree in anything uses or quotes Wikipedia. But at any rate, energy density by mass is a ridiculous measure used by no one in any terrestrial application.
gee thats great - lets runs cars and planes on U238 !
It would be nice if we could, but anyone with an "advanced degree" would know that U238 is a nearly stable isotope with a half-life roughly 1/3 the age of the universe. It's U235 that is consumed in reactors. Duh.
the BOTTOM LINE is that I can produce hydrogen in my house and run my car on it for about 5$ / gal equivalent - with no pollution or gasoline
The BOTTOM LINE is that you don't have any "advanced degrees" and don't have the slightest clue as to what you're talking about. You can "produce hydrogen" in your home only because somebody else is already burning oil, coal or natural gas at a power plant somewhere else, and creating pollution and burning molecules with a net positive energy yield there. Your hydrogen isn't doing anything but consuming energy in your home.
Your statements betray a pathetic misunderstanding of basic science: You're saying, "What's the problem? I can just plug in a wire and generate all the electricity I need to in my own home." Sure. Good luck getting that one past your high school science teacher.
Learn a little science, and don't bother to post to me again until you do. I'm not having an argument with a twelve year-old with a chemistry set who refuses to learn anything, and I'm certainly not having a discussion with an "engineer" who thinks Wikipedia is anything but crap. All the H2 on earth is already oxidized. It's not a source of energy. Period.
once again, you can try and insult me and change the subject but it doesnt change the fact that Hydrogen WILL be the main fuel used for transport in the near future
of course it must be created and is a carrier - not a primary source of energy.
so is EtOH- the current boondoggle idiot idea from congress, which is not only tripling food prices, but also takes much more energy to produce that it consumes
here is another incorrect quote by you “The liquid hydrogen used in the space shuttle takes orders of magnitude more energy to produce than it provides.”
this is NONSENSE
It takes about 30% of the energy to liquefy hydrogen- and electrolyzers are about 70-75% efficient
and you have no comeback to my point about stoichiometric mixing of Ch4 and H2 - because you are too stuck in your little box to listen
HERE IS THE POINT : WE NEED ALTERNATIVE FUELS
FUELS THAT ARE BOTH PRIMARY AND SECONDARY
ETOH SUCKS AND SO DOES BIODIESEL
the ONLY ONE THAT WILL WORK LONG TERM IS H2
you will be long dead when the pioneers of today, includng myself, revolutionize the energy industry.
have fun trying to pooh pooh progress from your little box, and ignoring arguments and changing the subject to suit your little box, like a liberal
and have fun paying $10 a gallon for gas soon, as the democraps keep preventing us from drilling as well
