Electric motors have none of the issues you describe, occasionally the carbon brushes fail on older style motors but it's just carbon with a wire attached.

As for batteries, China is mining massive quantities of lithium anyway, may as well put it to good use. But there's also enough lithium cells in discarded electronic products to build battery packs for millions of cars.
And perhaps the Lithium could be recycled to treat all you alarmist mental issues.

It becomes very cheap when you just pay for panel installation and do the rest yourself. Building battery packs costs nothing if you can snatch up battery packs from broken/old laptops, they're usually about 1 in 3 good cells.

(I use them for other stuff, haven't actually gone green on the house yet).

Way cheaper than a lithium battery module from a major manufacturer. Just wire them in parallel to make sections at 3.7v and wire those sections in series to push the voltage to whatever you need.
You're gonna need forklift batteries to really accomplish anything like charging a car or powering your home's AC.

Rick Perry confirmed by Senate as Energy Secretary, 10 Dems confirm...

There's your "resistance", folks..
That's pretty fucking sad all the way around.

It's clear the Democratic Party has completely forgotten whom they're supposed to be representing in their headlong rush to grab the money.

I think the core of the problem is runaway campaign funding- and therefore the solution to all this starts with a constitutional amendment to ban it. ALL OF IT.

I haven't been sold on them and so haven't dug too deeply into practical aspects like "who should/can I buy from". Nobody is profitable yet and reliability isn't established either. From what I've read, the early market is for businesses that buy thousands of units and there is not yet a residential fuel cell equipment supplier. But, here is a link to a list of manufactures of fuel cell tech:

https://en.wikipedia.org/wiki/List_of_fuel_cell_manufacturers

About 10 years ago I was part of a team that investigated fuel cell tech as a potential business opportunity for the company. What I learned at the time was that residential fuel cell power was potentially feasible. To me, the largest problem was the god awfully high temperature that is a requisite for efficient conversion of ethanol or propane into electricity in solid oxide fuel cells. Also materials in some solid oxide cell are exotic and scaling up this tech to any meaningful size will require either finding a new materials set or exploration for more sources of the material. That said, the problems didn't seem to me to require a major invention. The technology is feasible but for some reason we haven't yet seen the same kind of interest shown in electric or hybrid cars or solar.

After 10 years, I'm not surprised -- but disappointed -- that there isn't yet a major market or major distributor for residential fuel cells and I can't say for sure why.

After all this time, I'm still seeing this kind of statement coming from one of the players in the market:

What is the anticipated lifetime of the Redox Cube?
Under most operating scenarios a system such as the Cube should last for 10 years or more. Right now there is insufficient test data to validate this so initial systems will be sold with a warranty to alleviate any lifetime concerns.

My translation of the above: "this product doesn't reliably last 10 years". Their tech isn't ready for the market.
I'm hoping to use natural gas, aka methane, as the feedstock. Isn't the hydrogen reformer the part that has to be hot?

I hear about cellphone towers and giant Google server farms being powered by fuel cells. Maybe it isn't quite ready for prime time yet, but that when it makes sense to get in, at least to me.

Thanks for the link, I'd really like to talk with you further about this.

Global sea level rose about 17 centimeters (6.7 inches) in the last century. The rate in the last decade, however, is nearly double that of the last century.4

All three major global surface temperature reconstructions show that Earth has warmed since 1880.5 Most of the warming occurred in the past 35 years, with 15 of the 16 warmest years on record occurring since 2001. The year 2015 was the first time the global average temperatures were 1 degree Celsius or more above the 1880-1899 average.6 Even though the 2000s witnessed a solar output decline resulting in an unusually deep solar minimum in 2007-2009, surface temperatures continue to increase.7

The oceans have absorbed much of this increased heat, with the top 700 meters (about 2,300 feet) of ocean showing warming of 0.302 degrees Fahrenheit since 1969.


The Greenland and Antarctic ice sheets have decreased in mass. Data from NASA's Gravity Recovery and Climate Experiment show Greenland lost 150 to 250 cubic kilometers (36 to 60 cubic miles) of ice per year between 2002 and 2006, while Antarctica lost about 152 cubic kilometers (36 cubic miles) of ice between 2002 and 2005.

Both the extent and thickness of Arctic sea ice has declined rapidly over the last several decades.9

The number of record high temperature events in the United States has been increasing, while the number of record low temperature events has been decreasing, since 1950. The U.S. has also witnessed increasing numbers of intense rainfall events.

  • Since the beginning of the Industrial Revolution, the acidity of surface ocean waters has increased by about 30 percent.12,13 This increase is the result of humans emitting more carbon dioxide into the atmosphere and hence more being absorbed into the oceans. The amount of carbon dioxide absorbed by the upper layer of the oceans is increasing by about 2 billion tons per year.

And Gallileo was once alone... faaaar less than 3%, when he said the earth was round and revolved around the sun.

Look how that went for him.
False equivalency; no one else was actually doing the science in Galileo's time. Climate change and accelerated global warming are the consensus of THOUSANDS of scientists around the world working in dozens of different fields, all coming to the same inescapable conclusions.

If you'd like to be taken seriously, try something more substantive than Faux Spews taking points; starting with a desired outcome and ignoring all evidence that doesn't fit isn't science; IT'S DOGMA. Try to learn the difference.

@morvis Well, would ya look at that; findings from many different scientific disciplines all pointing to the very same conclusion.

Galileo was alone in his work. The only similarity between him and our times is the religious fervor of his opposition in face of the facts.

Yeppers, I live in a place where we have winter, This year in Feb. it was in the 50s, all my life never seen temps above the 30s in feb. even seen grass in my yard. I do not know where people live not to notice the warming.

2nd year in a row Lake Superior hasn't had Ice on it, I mean I've been here on the South shore for over 50 years, and have not seen that happen, the water temps last summer was in the 70s less than a mile off shore, that just has never happened here before, I am used to the water in the 50s not 70s and this year I would imagine the temps are going to be up again. That alone has so much to do with our winters here being abnormally warm.
Sure we still have cold weather, but it's nowhere near what I am used to, We have to worry about pollution, cutting the Clean Water Act from 300 million to 10 million, Could I ask Trump Supporters what more do you have to see before you agree that these policies he is passing with Scott Pruitt. will be devastating on our waters and waterways.

I believe your Greed is clouding the vision and our rights to have Clean Air and Water.
The people that want to do Fracking,(Head or Our EPA now) look at Oklahoma right now, they have more Tremors than California, do you want to drink water out of a machine? I have a artesian well, at my house, I can drink water straight from the ground, and it is awesome. I really would like my children's children able to do that.
But what is in the process of happening at this point doesn't look good for that to happen for my family, and why shouldn't it? We are at a tipping point now, and may be past it. After all what good is it if everyone has a job, when we can't breath the air or drink fresh water.

The core of the problem is the ability of corporations to buy politicians. Outlaw campaign finance in all its forms, on pain of 20 years in Federal prison and we'll see a lot of this shit get reversed in a hurry.

I agree 100% and know you're right, Outlaw it all.
Just can't believe how many don't see that.
I will and am on that bandwagon with you.

Table on second page breaks down the different technologies. The only companies that I've seen hype their products as "residential fuel cells" use SOFC or solid oxide fuel cells. They are the most efficient and can achieve 80% efficiency when coupled as a heat source in addition to electricity. The the cell operates at about 1000 C and the active component is zirconium ceramic doped with yttrium. This has been around for a long time. They are now making them commercially but I've read that they are working with larger customers for now.

Then don't call yourself a Democrat. Caucus with the Republicans if your district wants you to vote Republican. Democrats are supposed to represent Democratic interests. Republicans can push Perry through without a single Democratic vote and yet they still bend and fold like absolute pussies under the pressure. The fact they'd vote for them just to keep their job shows they are absolute pussies without conscience and absent all moral fortitude.

Only a bitch would want to keep somebody like that in office
OK, so that's a dead end for the Democratic Party. Honestly, I thought you maybe could count. But I was wrong. Look at the map of red and blue states. Control of Congress depends on red state democrats holding their seats while others unseat conservatives in purple states. Most of those blue dog democrats are fiscally conservative but moderate or liberal when it comes to social issues. A few are social conservatives. They all oppose the ideology of the radical right. The radical right is fascist,which is neither conservative nor liberal.

When Bernie Sanders submitted a bill to repeal the Citizen's United rulings, every one of those Blue Dog Democrats voted with Sanders. If you were to ask other Democratic congressmen or an Independent like Sanders if they would be better off without conservative democrats, they would say no. As I said, your purity test is a dead end and wouldn't achieve the goals you want.

You are pretty simple when it comes to ideology. It's your way or no way. It's a losing ideology.

I'd rather be alarmist than stupid. Recycling Lithium batteries using today's tech is inefficient and creates yet more waste to dispose of.

We need smart ways to recycle metals found in trace amounts in electronic product waste. Here is an interesting idea:

Fungi recycle rechargeable lithium-ion batteries


The team first dismantles the batteries and pulverizes the cathodes. Then, they expose the remaining pulp to the fungus. “Fungi naturally generate organic acids, and the acids work to leach out the metals,” Cunningham explains. “Through the interaction of the fungus, acid and pulverized cathode, we can extract the valuable cobalt and lithium. We are aiming to recover nearly all of the original material.”

Results so far show that using oxalic acid and citric acid, two of the organic acids generated by the fungi, up to 85 percent of the lithium and up to 48 percent of the cobalt from the cathodes of spent batteries were extracted. Gluconic acid, however, was not effective for extracting either metal.

the democratic party should be the most diverse party but is has made of 30, 40% those who want it more progressive vs 50, 60% of people in the republican party wanting that more conservative. There are democrats probably about 30 % that are old school dems from pre cival rights (some are young) they vote law and order via war on drugs and there are the pro capitalist business democrats who are blue team leaders too. the other 30% or so are swing or moderate or have other issues and agendas that influence the party. the right has progressives that are for school and correct history and human rights only through absolute rule. these are not the leaders of the party but nor are the left wing progressives in command of the left.
using duct tape to hold one's asshole open barely seems consensual to me, even at the most highly paid rate.
what if thats what i'm into it and i'm an adult? there are less glamorous ways to get payed for sex. that bing said [spoiler alert] ever look at womens faces doing porn? thats how you know how moral it is. most are very high as in drugged. there are those that are genuinely having a good time and proud but there are those who are there as a last resort and ones that are crushed and lives are ruined with stds and ptsd.
