there are things you can do that can be more effective than an air purifier.
First, ban indoor smoking.”If you’ve got a smoker in your family, you
should not let them smoke in your house because that’s an incredibly large
source of pollution in the home,” . It seems like everywhere I go, people have an air purifier running. No
one wants to breathe dirty air. Just remember a machine alone, won’t clean the

Comment on A Vision for Nuclear That is no Longer Unclear – Fusion by NeilFarbsteinhttp://www.greenoptimistic.com/2014/10/16/vision-nuclear-longer-unclear-fusion/#comment-43071 Fri, 17 Oct 2014 02:57:44 +0000 http://www.greenoptimistic.com/?p=49686#comment-43071 Chemonuclear Fusion is a
type of low energy nuclear fusion that has been shown to produce
energy in two experiments. Aneutronic nuclear fusion can provide
unlimited electric power without polluting the environment with
radioactive waste and greenhouse emissions. Chemonuclear processes in
small dense white dwarf stars accelerate the rate of nuclear fusion
and cause them to explode in spectacular supernova explosions.
The
mission of the Chemonuclear Fusion Project is to raise awareness of
this new and vitally important source of environmentally clean energy
and to promote research and development.
The Chemonuclear
Fusion Project is soliciting volunteers to help our crowdfunding and
educational campaigns. Our crowdfunding webpages will soon be up and
running. We want people to post to discussion groups and help us get
the word out that aneutronic chemonuclear fusion might be the
radiation free way to power the world if we can get the funding to
build and test reactors.
Artists can help us design T-shirts,
mugs, and promotional items to sell and give away to our
contributors. Writers to write promotional materials and post to web
forums are also wanted. Video producers and professional and amateur
scientists who can help the public understand the concepts of
chemonuclear fusion are encouraged to contact us also.

You just need to wash an aluminum pot once to see how much of it gets into the washing water, so you can guess how much of it gets into our food, hence into our bodies. Certainly nothing good can come from ingesting aluminum in such quantities. Besides health, there’s also an environmental aspect: Mining and refining the aluminum ore is a very polluting industry, generating toxic mud, so reducing our consumption of it and making sure even the foil around the chocolate bars gets recycled too is important.

I hate these TV cooking shows that are always cooking or marinating meat covered in foil. Can’t chefs buy stainless steel lids for their oven pans? Disposable aluminum is the ultimate waste of resources, especially since most of that foil never gets recycled.

Comment on Solar Hydrogen Starts to Rock Thanks to Dirt Cheap Stuff by Ari Luishttp://www.greenoptimistic.com/2014/10/12/solar-hydrogen-starts-rock-thanks-dirt-cheap-stuff/#comment-42846 Mon, 13 Oct 2014 23:35:41 +0000 http://www.greenoptimistic.com/?p=49608#comment-42846 Good point. It’s so much easier to put up a charging station than a refueling station. Heck, we could even charge our EV in the garage.

Methinks that this would help the space industry a lot, though, Cape Canaveral being at the Atlantic coast and all. After all, hydrogen is still the fuel of choice there.

Oh!, did I forget to say that fuel cell cars are basically BEVs with complicated and so far expensive, fuel cell generators in place of ICE generators?  One might then classify them as hybrids.  Sorry, I forgot that.

Fuel Cell car may have some advantages over BEVs; but, refueling is not one of them.

Buying a vehicle is a very personal decision, which is why people name their cars and other means of transport (I used to name my old car Alex and I call my current ride, a bike, Willy Felt). Since we already own these vehicles, we do have a right to make the mods that we want to give them a more personal flavor. If the mod we’re looking at involves tinkering with the original hardware like the battery and engine, or even with the software, the car company’s CEO has no right screwing with that!

Comment on Removing 7,000 MW of Coal Plants from the Western Grid is Possible by Ari Luishttp://www.greenoptimistic.com/2014/10/07/removing-7000-mw-coal-plants-western-grid-possible/#comment-42800 Mon, 13 Oct 2014 02:44:08 +0000 http://www.greenoptimistic.com/?p=49536#comment-42800 The slack will be picked up by natural gas? Well, you’re actually on the same page as the study authors. With the amazing developments being made in solar power and energy storage, distributed generation, as opposed to centralized power generation, is becoming a reality. It also helps that the load profile of the California Independent System Operator, one of the bigger electrical systems in the western grid, looks more like a duck with a decreasing base load requirement, reducing the need for base load plants like coal.

The study says that further research needs to be done, and your idea of “small plants and small grids that are independent” is something that should be definitely looked at.

Instead of boxy looking 1 1/2 to 2 inch thick framed Gen 1 solar panels, these new higher performance Gen 2 solar panels are only 1/4 inch thin and are made with a stronger, see through, glass on glass, frameless, construction that allows sunlight to pass through and reflect off the roof’s surface, thus illuminating the backside of the double sided solar cells, producing additional power. 

A mere 10% boost in reflected light can raise this 340 watt solar panel’s output to 374 watts without taking up anymore roof space. New Hyper X 2 solar offers a better PTC to STC ratio “Real World” performance according to the California Energy Commission’s performance rating listings than over 100 of SunPower’s solar panel models. 

And they offer a very high 92.88% PTC to STC performance ratio. Hyper X 2 also offers a heat resistant -0.31%/degree C temperature coefficient for better performance in warm/hot climates. And when it comes to aesthetics, nothing even comes close to Hyper X 2’s glass on glass, see through, frameless construction. 

With N-type mono-crystalline bifacial cells for double sided power production, up to a 21.5% efficiency rating, superior aesthetics, and a price that outcompetes the solar lease and PPA company’s offerings, nothing compares to Hyper X 2.

Yes you can remove 7000 MW from the grid but other coal fired plants will have to pick up the slack. Don’t believe everything you hear. Going to more centralized power generation is a bad idea because your putting all your eggs in one basket so to speak. Better to have small plants and small grids that are independent so they cant all be taken down at once. You can get rid of the coal plants when you have a plant of equal capacity ready to go on line. Otherwise your just cutting a leg off the horse you are expecting to ride. Reality sucks huh?

Comment on Will We Ever Break Free From Fossil Fuels? by LoneWolffehttp://www.greenoptimistic.com/2014/10/07/will-ever-break-free-fossil-fuels/#comment-42647 Wed, 08 Oct 2014 13:52:50 +0000 http://www.greenoptimistic.com/?p=49541#comment-42647 Chimel True, developing countries don’t need to invent anything new. They can at least adopt, but this will cost. Take, Peru and Ecuador, for example. They are both rich in natural resources, including fossil fuels.  What technology do you think they’ll turn to first when it comes time for growth? Will they look outside their borders for renewable energy technology? More likely, they’ll look to whatever fossil fuels are already within their borders, a much cheaper and easier option.
Personally, I would hope that these countries would look at the long-term, rather than the short-term, gains. On the other hand, however, there are more than enough mining companies willing to strip these countries bare of their natural resources, and enough politicians to accept their bribes to overlook the damages. Even if the enlightened ones were in control, opting for a renewable energy plan for the country, two other outcomes would be likely. One, there are still plenty of unenlightened ones to push for extraction and use of fossil fuels (this explains OPEC member states’ push for renewable energy within their borders). Two, the locals would say, “Why are we spending our money on foreign technology instead of just mining what’s right beneath our feet?”

Not really relevant or as important as is being made sound like: Not a single one of these developing countries needs to invent new renewable technologies, they are already all there for the taking, they just need to purchase existing technological hardware and designs, like solar panel, wind turbines, and there’s dozens of countries and companies that would be more than happy to install them for these countries until they have acquired the know-how from their own education programs.

Financing is a more difficult question, but most of these countries are in high insulation areas where the solar ROI would happen in half the time needed for countries like the USA where new solar power plants are already competitive with coal and getting closer to natural gas every day, so you’d think that for these countries at least, solar would make a lot of sense. Also, many of these countries don’t have a costly national grid the scale of the ones maintained by developed countries, so local distributed solar plants could be much cheaper than trying to emulate the Western World centralized grids. Also, many of these countries don’t even have coal or coal mines, or a good road and train grid, so coal is not even an option if you need to import and transport it.

There are no doubt many other variables at play, so I don’t think we can make the  kind of generalized statement as above, the situation needs to be studied and assessed for every single country before the results can give us such a generalized view. For me, the fossil fuel situation resulting from developing countries is not as dire and is more nuanced. Despite the catastrophic situation in China, their carbon emissions per person are still half those of the USA, for instance, and they now have a solar energy plan that’s more ambitious than any other country in the world. They’ll still have pollution from coal power plants to deal with for decades, and these will affect the whole world too, but there’s a strong national will in favor of solar, and in a strange way, the lack of democratic processes similar to the Western World makes it easier for China to implement such a renewable energy plan. And the USA is so behind its times that it probably won’t take long for China to be a world leader not just in solar cell production, but in solar energy production too. Equipping their own country with solar is also an incredibly smart way of dealing with the past overproduction of solar cells. My 2 cents.

Regarding crops watered by the rain, any runoff would still have to be treated for human consumption. On the other hand, some crops, such as the almond crops in California (could be the same for grasses and grains in other places) are watered via irrigation is practiced, and huge quantities of water are diverted.
In that case, the water cost is huge, and downstream ecosystems are seriously unbalanced.

That would equal to a regular danish cow needing 40 000 liters, or 40 tons of water a day, to produce it’s 20 liters of milk. A high-performing dairy-cow drinks about 150 liters a day. 
Of course there is the fodder, and some other elements in the equation, but I find it really hard to believe that this should amount to anywhere near 38 500 liters of water a day, per cow. Actually, I would even find it hard to believe that it should amount to more than 100% of the cows direct need for water. 
How is this calculated?

Comment on How Would You Survive A World Without Fossil Fuels? by LoneWolffehttp://www.greenoptimistic.com/2014/07/31/survive-world-without-fossil-fuels/#comment-42551 Mon, 06 Oct 2014 15:17:58 +0000 http://www.greenoptimistic.com/?p=48723#comment-42551 KingsleeSpurling Conspiracy theories aside, however, fossil fuels are still “the easy way” and “the cheap way,” but I believe that people are slowly coming around to the fact that the long-term costs of continuing fossil fuel use outweighs the short-term savings. (Renewable energy is already cheaper than fossil fuels in some places.)

Comment on How to Build an Electricity-Producing Peltier Gasifier by mangyhyenahttp://www.greenoptimistic.com/2013/02/13/how-to-build-gasifier-peltier/#comment-42465 Sat, 04 Oct 2014 16:43:47 +0000 http://www.greenoptimistic.com/?p=33163#comment-42465 An easier way to protect the Peltier module from excessive heat from the stove is to use a heat exchange liquid as the Peltier’s heat source. Mineral oil should work well in this application. Using a thermometer to monitor the mineral oil’s temperature as it heats up on the stove, remove the pot of mineral once it reaches the Peltier’s maximum working temperature.
Sandwich a Peltier module between 2 metal reservoirs.
Pour cool water in cold-side reservoir, then pour hot mineral oil into hot-side reservoir.
Viola, a well controlled heat source with no risk of damaging the Peltier with excessive heat.
Use stove to heat more mineral oil than the reservoir needs & store excess oil in a thermos. Refill reservoir from thermos as needed for electric generation long after the stove is shut down.
Can use any clean heat source to heat mineral oil for powering Peltier; rocket stove, methane gas burner, concentrated solar, any suitable waste heat…whatever. This truly a multi-fuel method.

So, follow instructions & sandwich the Peltier between 2 radiators or liquid reservoirs.
1. Put cool water in cold-side reservoir.
2. Heat mineral oil up to the Peltier module’s maximum working temperature. (Use a thermometer to monitor the oil’s temperature and remove oil from the burner or rocket stove or solar parabolic dish/trough once desired temperature is reached.)
3. Pour hot mineral oil into the hot-side reservoir.
4. Use or store electric output.
5. Reheat mineral oil as needed. Or, heat more mineral oil than you need to fill the reservoir, store excess mineral oil in a thermos and refill hot-side reservoir from thermos as needed.
Rock on.

For example, if a gallon of diesel in a farm tractor can do the work of 25 men, that means that we can plant more and harvest more. Petroleum-based insecticides and herbicides give us bigger yields. Hence, we can feed more people with a gallon of gas than we can with manual labor.

From Car & Driver Will Hydrogen Be Cheaper Than Gasoline? Who Knows?http://www.caranddriver.com/features/pump-it-up-we-refuel-a-hydrogen-fuel-cell-vehicle-hydrogen-filling-stations-are-still-rare-page-3
The pump we used quoted the price of hydrogen at $5 per kilogram. The actual cost for pump hydrogen in the future is difficult to estimate with any accuracy, though, since the volume and infrastructure aren’t yet mature. Balch cites studies that foresee the price of hydrogen leveling off between $2 and $4 per kilogram, and he points out that a kilogram of H2 typically provides more range than a gallon of gas. Once the price of hydrogen does come down, it should carry a cost per mile that’s similar to or better than that of gasoline. Better yet, once established, the price is not expected to fluctuate with the same volatility as that of gasoline.
So although the process of pumping hydrogen into a fuel-cell vehicle is pretty simple (and getting simpler), the process of pumping hydrogen into our infrastructure could be one of the great challenges of our generation. At least we can look forward to keeping our hands clean.
The ix35 Fuel Cell is equipped with a 100 kW electric motor, allowing it to reach a maximum speed of 160 km/h (99 mph). Two hydrogen storage tanks, with a total capacity of 5.64 kg, enable the vehicle to travel a total of 594 km (369 miles) on a single charge, and it can reliably start in temperatures as low as -20 degrees Celsius.
GOOGLE:  Hyundai ix35 “Tuscon” Fuel Cell Vehicle
5.64 x $5 = $28.20 to travel 369 miles
5.64 x $4 = $22.56 to travel 369 miles

It was also once cheap, which was it’s greatest appeal. That hasn’t been the case for a considerable time, with every indication that with increasing demand & diminishing supply prices will keep rising.
Most motorists aren’t environmentalists but they ARE personal economists. Hydrogen in the UK is supposed to be the cheapest fuel now available, selling at half the cost of diesel. THIS is the “music” that appeals strongly to motorists everywhere. Just ask any cab driver. Drivers aren’t turned on by news of commuter type, battery powered, electric cars, with limited range & speed. Plus the idea of having to wait at home or a recharging outlet for an extended time for their commuter car to recharge isn’t going to cause a sales stampede.
This is where hydrogen fuel cell technology shows its clear superiority. The fuel is cheap. We can never run out of water because after being used in the fuel cell, the hydrogen becomes water as it once was. [ Water broken down by electrolysis to produce this hydrogen fuel is returned to the environment as harmless, non-polluting water once it's completed its use in the fuel cell.]
Secondly, the motorist isn’t being asked to drive a “tinky toy”car in the name of climate change & saving the environment. Good hydrogen cars have equal speed performance to petrol cars currently on the street & a range of almost 400 kilometres before needing refuelling. Refuelling only takes a few minutes, just like petrol driven cars & is just as easy.
This is what attracted me to this technology. The motorist DOESN’T have to compromise in the name of climate change by driving an inferior car. Different technology, no pollution, but same performance & we won’t have to worry about running out of fuel or the harm it’s doing to our environment. As a final example, if you parked a Mercedes Benz B Class F Cell beside a B Class with standard petrol engine, most people would swear they were identical. The only, external difference being, the petrol engine version has an exhaust pipe.

SolarCity’s own blog states they’re hoping to go nationwide offering Tesla battery backup next year. WIth the launch of the gigafactory, ALL of SolarCity’s will come with Tesla battery backup, which is expected by the end of the decade, as I mentioned.

As far as the 24% number, I can’t find my source. I should have had it linked, but somehow it seems to have disappeared. In any case, even your 18.3% efficiency is incorrect, as I found from Silevo’s site, their new technology braking 22.1% “with headroom to reach 24%”: http://silevosolar.com/category/product/triex-technology/efficiency/ damned if i can find where i saw that 24% number more certain, however.

Next time, instead of going the conspiracy theory route, why not ask a question? You’ll live longer.

You should have asked SolarCity, another Elon Musk (Tesla) company: They offer recycled Tesla batteries to SolarCity solar array hosts for free. If it seems logical to you and me, then someone must be doing it already!  ;)

I don’t think Elon Musk has ever said what the name of the factory really is. As far as I know, he’s only said “the” gigafactory. Someone capitalized it and turned it into a name, I think.

The car makers, including Toyota, and The Energy Utilities would do well to maintain a good relationship with Tesla and follow the company’s lead as they solve the problems, implement the technologies and chart a clear path to the cleaner, greener energy environment many so desire.  Remember, Tesla shares their intellectual property openly. with those who act in good faith.

By the way, Tesla’s Giga Factory is not an appropriate name for this new business.  It needs a better name.  How about something like “ContainedEnergy.” etc.

accepted laws of physics, there is no way to extract chemical energy from water
alone. Water itself is highly stable—it was one of the classical elements and contains very strong chemical
bonds. Its enthalpy of formation is negative (-68.3 kcal/mol or -285.8 kJ/mol), meaning that energy is
required to break those stable bonds, to separate water into its elements, and
there are no other compounds of hydrogen and oxygen with more negative
enthalpies of formation, meaning that no energy can be released in this manner
either.Most proposed water-fuelled cars rely on some form of electrolysis to separate water into hydrogen and oxygen and then recombine them to release
energy; however, because the energy required to separate the elements will
always be at least as great as the useful energy released, this cannot be used
to produce net energy.In addition to claims of cars
that run exclusively on water, there have also been claims that burning
hydrogen or oxyhydrogen  in addition to petrol or diesel fuel increases mileage.
Whether such hydrogen on demand systems actually improve emissions or fuel
efficiency is debated.A number of websites exist promoting the use of
oxyhydrogen (which they often refer to as “HHO), selling plans for
do-it-yourself electrolysers or entire kits with the promise of large
improvements in fuel efficiency. According to a spokesman for the American Automobile Association,
“All of these devices look like they could probably work for you, but let
me tell you they don’t.

Why? you ask!……..because their legacy cars are profitable and their only goal, driven by Wall Street, is to make money for their shareholders.

On the other hand, Tesla is potentially the World’s Largest Battery Company, who at this point is developing a BEV market and a grid edge storage market for their future battery business.  They have a different goal.  Musk says he wants to save the human species by cleaning up the Planet.  In the process, I see him building a group of very profitable companies, especially the battery business.  Some say batteries are a multi-trillion dollar business.  

While car companies are sleeping, Elon is reaping!

Investing in the proper technology: good solar panels, charge controllers, a good deep cycle battery pack – makes a big difference in making the whole system work.

How do you adapt to a GLOBAL CLIMATE CRISIS or as the lab coats call it; “a threat to the planet”?
It’s 32 years of nothing beyond “could be” and “95%” certainty from science so what’s to “believe”? You can’t tell kids science “believes” as much as you remaining eager “believers” do.
Is science also only 95% sure the planet isn’t flat when they say they are only 95% sure CO2 “could” cause a global climate crisis?
Try a word search with any IPCC warning from the last 30 years and you will not find any of these words;
“will be a crisis” or “proven” or “eventual” or “inevitable” or “100%” proven. 
But you will find these words of “certainty”;
“could be” and “possibly” and “likely” and their laughable; “95%” certainty that THE END IS NEAR.
Exaggeration of science by “believers” can’t be denied.

While the battery chart you posted (which seems to have come from http://www.solarelectricsupply.com/solar-batteries/deka-solar-batteries) is for a deep-cycle battery, people reading might not realize that your recommendation of 30% is more in line with the discharge amount for a starting battery rather than a deep-cycle battery (which are frequently advertised as being rated for discharge at or near 50%).

Second, since I wrote the review about the ArkPak and have interviewed the folks making it, I can tell you that the charger/reconditioner in the unit is world-class. While a battery’s ability to recover from multiple deep discharges is largely determined by design and quality, a good smart charger makes a huge difference. The ArkPak’s charger has 7 modes, can push out as much as 6amps, and is carefully calibrated to help maximize the life of deep-cycle batteries.

Finally, just as your graph shows, daily discharges of 50% would still result in years of service.
