How Fort Irwin Just Signed The Largest Solar Farm in Dept of Defense History: 1,000 MW


In a win-wIn move for the US Army and the USA, a mutually beneficial financing arrangement was signed this week between the US Army and a new partnership (”Irwin Energy Security Partners LLC”) comprising Clark Energy Group and multinational solar power giant Acciona. By using Enhanced Use Leasing they can now not only finance the solar project for Fort Irwin, but double the size to 1,000 megawatts.

The solution they came to this week provides a model for how to get around the difficulties encountered by utility scale solar companies in getting past NIMBY opposition and other roadblocks to developing big solar in the desert.

60% of US States Could Supply 100% of Their Own Power From Renewable Energy, New Rules Project Shows

Using just the resources that are currently commercially deployable; 31 of our 51 states, or 60% of US states could get 100% of their electricity from renewable sources in-state, and another 14 percent could generate 75 percent of their electricity in-state, according to a paper published by New Rules Project that focuses on the potential for local production.

In some ways, very local; which actually makes this a conservative estimate. For example:



Solar. The New Rules Project study looked only rooftop solar potential, and not the obviously far larger utility-scale solar potential as the idea was to see what could be done with existing resources only in each state, and not adding transmission lines.

(Strangely; the authors inexplicably omit waste biomass or waste fueled electricity, like from landfill gas, cow power and sewage sludge as sources for producing electricity, that has tremendous potential. There is no peak poop, after all. )

But it still has a wealth of detailed data (2007), well presented in these graphs showing the relative resource for each state for

Bugs Will Fly You to Europe By 2030 Says Boeing












September 2008:
Bugs won't be piloting the plane, obviously, because bugs can't get pilot licenses. I hope I didn't give you that impression. But they will be fueling it. Microbes will be fueling aircraft, says Boeing and algae will be the dominant aircraft fuel by 2023.

Darrin Morgan, who handles Boeing's biofuels strategy says Boeing has now established feasibility, and commercial production will soon begin. Boeing conducted the first commercial aviation non-algae biodiesel test flight in February with Virgin Atlantic and GE Aviation, and they now plan the first algae-based biodiesel flight from Auckland to San Francisco this month.

Before you say that this is just green-washing, let me tell you that Europe won't even let our planes land after 2012 if they can't meet the kind of emissions standards that can be devised by lobbyist-free government, such as they are blessed with in all those other countries.

Oh, wait, I see that that harsh rule has been modified recently, after airline industry howls of protest. Now they must just pay a little more to pollute, but they can at least land. Thank goodness for lobbies. But meeting these low CO2 requirements as hardly hurt Boeing sales, and their fuel efficent Dreamliner has even caused runups in worldwide carbonfiber prices.

New Zealand has set a similar standard to the EU requirement: new regulations increasing biofuel use by 2012. The prime minister there has committed to getting New Zealand 90% renewably powered by 2020 - she has made it to seventy percent so far - and that means planes will have to meet those standards too, when they refuel in those nations. So as you can imagine, the New Zealand startup Aquaflow supplying the bugs fueling Boeing's test flight, announced in March that they are gearing up for major production.

Even tiny Island nations like New Zealand could supply behemoths like Boeing all the algae they need to get us to Europe. That's because, with the exponential doubling growth rate of microbes, algae does not need a lot of space to manufacture enough algae to power our planes.

If we keep siphoning it off, of course. Which, no doubt we will.

Ancient Tiles to Solar Power Your Home

solepowertile1
These gorgeous Solé Power Tiles are designed to capture and convert sunlight into cost-saving electricity without compromising aesthetics. They incorporate UNI-SOLAR thinfilm flexible solar cells shaped into exaggerated traditional clay tile shapes.

The flexible “triple-junction” solar cells absorb a comparatively broader range of the sun’s rays than conventional modules, allowing them to generate electricity for a longer period of time each day. They "wake up earlier and stay up later", than other solar cell devices.

They are actually pretty effective, too:--


The tiles are rated at 1 KW per 200 sq. feet, which is about 1/3 the typical American home's kwh requirement using about a living-room-size space on a roof.

Most houses would have the space to fully power themselves using these solar tiles.

1 KW per 200 sq ft is fairly comparable to Uni Solar's regular thinfilm, which is designed to just peel and stick on flat metal roofing, -- utilizing the benefits of selecting optimal South facing slopes.

But that leads to the question - Does this take into consideration that tile roofs are generally a wildly mismatched assortment of angles on all the gables; every solar estimator's worst nightmare.

These PV tiles will inevitably face both sun friendly and unfriendly directions:

Look at the pictures: what percent of these arrays are actually South facing? The North facing arrays will only generate about 70% -- and the East/West arrays will only supply about 85% of what perfectly aligned Southern exposures can do.solepowertile2
On the other hand, there is a lot to be said for having a uniform color to the entire roof, regardless of how little electricity some of these tiles will generate. And on the typical home there is enough roofspace that they can easily generate the 400 to 800 kwh per month that the average home needs.

SRS Energy will be launching Solé Power Tile at the American Institute of Architects 2009 National Convention and Design Exposition to be held in San Francisco April 30. So next time you have to replace a roof -- you can just install your own personal electric power station up there, disguised as your scrumptious new tile roof.

Cube House Displaces Landscape to Roof

Here's a really interesting idea.
outtrialhouse3
Build a huge white box house, and take the lawn it displaces and just move it up a level.

outtrialhouse2
Literally “carve out” a piece of the grass-covered site that is used by the building footprint, move it up and treat it as the roofing. Then arrange all the usual required functions 0f the house underneath.

outtrialhouse4
What is most extraordinary about this design, though, is that the huge grass roof is only accessible from inside the house, up these internal grass stairs.



outtrialhouse1

The newly-created roof "deck" space has all the advantages of an outer garden while remaining a safe, internal zone "within" the building.

This structure is not as it first appears; an earthsheltered house tucked into a grassy mound, with a grass stairway entrance down into the house.

outtrialhouse5
It is actually a completely freestanding box shape house. Albeit - with a private grass stairway to a grass roof in the middle of the house! Here you can see the underside of the grass stairway coming down from the roof.

This is a completely original design for a house.

Existentially Scary Freeway Home for a Meltdown Economy

Architectural works are often described as "stunning!".

Taking that impact one very giant step further, here is a very surreal work by Ensamble Studio (engineered by Inorganic Matter Company) that is frankly designed to not merely stun — but to actually alarm.

hemeroscopium1 architecture

Almost every angle, material and juxtaposition in this home is designed to make you frighteningly uncomfortable. Unstable. Uneasy. The sense is enhanced by balancing these huge heavy unstable structures.

Yet there is something exhilarating about this feeling of alarm, especially for a swimmer, swimming out into some existential nowhere in this lap pool to eternity:

hemeroscopium2 architecture

The surreal pool extending out into the distant horizon would give you pause. The uneasy feeling would be topped off by this enormous Stone-Henge like lump of unworked concrete on top of the concrete beam that welcomes you as you make your return lap back “home”.

hemeroscopium5 architecture

Perhaps it is an appropriate feeling to engender in those wealthy enough to afford to build what really amounts to a small freeway to live under, as the second gilded age comes crashing down around all of us globally.

This gratuitous chunk of concrete is just waiting to crash down on you as you swim in your lap pool towards eternity…

Perhaps this Spanish architect has tapped into a kind of existential terror of our times - that a freeway overpass is being subconsciously considered as a place to call home.

Even those still rich enough to build that freeway now –are somehow tapping into the ultimate terror, the zeitgeist of these economic times: Homelessness.

Harsh Home to Survive Australian Climate Change

kangaroovalleyhouse1 green
Here’s another house designed to supply all of its own needs in the harsh Australian outback in an uncertain climate future: Kangaroo Valley House.

This home away from home is designed by the prolific Australian architect Alexander Michael to manage and thrive completely on its own.

(Michael is a bit of a survival fetishist: he makes his pied a terre in the city in a reconstituted nuclear missile silo.)

kangaroovalleyhouse2 green
But this is his cheery holiday home for friends in the outback. Completely open to the elements, it is designed to scoop up all the possible air to cool itself. The solar power on the site supplies the basics; there is no air conditioning.

kangaroovalleyhouse3 green
The entire roof acts as a rainwater catchment device, designed to funnel every last drop directly down into the giant cisterns in the back. Not only that, the rainwater-harvester roof is engineered to cool the house below with shade, because it is not attached to the house itself: an airway passes right through between the two roofs.

kangaroovalleyhouse4 green
The top roof also makes possible this heavy slab of concrete with no support at the edge. The concrete slab in front is suspended from the roof. The top roof is supported on posts right in the reflection pool.

kangaroovalleyhouse5 green
Inside, no walls obstruct the airflow. Virtually every wall can open to allow the passage of air. And if that exposes the plumbing? Who cares.

As Michael says: “The thing I love most about design, whether it’s a mechanic’s tool or a multi-story building, is to see how it’s put together and what makes it work. When these features of machinery are denied by covering up, or burying out of sight for no other reason than decorative, then I think is a terrible waste. I guess it’s the same reason I love to stare at the skeletons of great whales, or fish, or humans; it’s all architectural machinery, its function is to support, and it’s beautiful.

kangaroovalleyhouse6 green
In this climate, it is a pleasure to walk outdoors to the sleeping quarters. This simple house supplies its own water, power and air conditioning in a harsh climate. Maybe we can be self sufficient. Our houses can be designed to supply these needs and protect us from climate change. Other Australian architects have gone here before: the house designed to survive wildfire is an example. This is a new development in architecture: design for climate-change survival.

Planet-Cooling Technology at Your Fingertips

inletoutlet

Here's a charmingly altruistic idea for those of us who would love to help to green the grid to cool the planet but just can't afford to invest in a full roof of solar panels just to lavish lots of climate-friendly electrons on others.

The Inlet-Outlet plug.

Lets say you have a little roll-up solar panel or solar-topped table or solar backpack charger that you regularly abandon at home while you are out at work during the sunny hours of the day.

It could be making useful electricity for someone else, right?

Just plug it in to this inlet/outlet socket and let it send its sun-harvested electrons out into the grid for others to use, while you are out of the house. (You'll have to have this plug near the window, of course). And harvest your sunshine for the common good.

Perhaps your utility could be persuaded to credit you for the electrons you send out, and it could reduce the amounts you owe. If not, perhaps congress could help persuade it. You'd have to ask congress.

And maybe over the years you would wind up gradually acquiring enough of the little portable solar chargers to get to the point where you actually make quite a dent in your electric bill that way, by sending in these free electrons to counter the ones that you'll use when you come home at night, yet you would never have had to come up with the financing for an entire roof- full of solar panels.

A really great idea. Kudos to Carla Diana and Jeff Hoefs of Smart Design for this decidedly Greener Gadget.

TH!NK EV Saved! Made in America 2010?


In December, amidst much gleeful hand-wringing schadenfreude, the imminent demise of all the alternative car companies and electric vehicle start-ups was all over the intertubes, as our second Gilded Age crashed this fall into "the worst depression since the Great Depression".

Headlines full of screeches like "Oh no! Tesla sedan delayed five minutes! Now surely they will go out of business!" "Another EV startup bites dust!" were all over the gleeful media.

Among these alarmist statements was a much touted story about the near-death of TH!NK, the Norwegian EV maker, which had been scheduled for U.S. delivery in 2009.

Never mind that TH!NK had placed a $70 million dollar battery order with Enerdel a few months previously. Now, all was lost. No $25,000 freeway speed EV for America.

Well, think again, pundits.



After the virtual collapse of the company last month, the U.S.A. (where the original TH!NK was murdered by U.S. lawyers fighting CARB zero emissions rules in the 90's) could be just where the TH!NK gets resuscitated this year. How ironic.

Autobloggreen reports

"After its virtual collapse last month, there are now renewed signs of life at Norwegian EV maker Th!nk. Ener1 Group Inc. is one of the investors in Th!nk and it's Enerdel division had been set to supply Th!nk with lithium ion battery packs for its City car, as well as future products.

According to Ener1 CEO Charles Gassenheimer, the company is looking at significantly upping its ownership stake in Th!nk. Half of the $5.7 million cash infusion that Th!nk received in December came from Ener1 and "Th!nk may need up to $40 million to get production going. Gassenheimer believes the company could easily sell 10,000 of the City cars annually in the U.S.

In conjunction with the [advanced vehicle technologies] DOE loans that EnerDel has applied for to fund increased battery production capacity, Gassenheimer is now looking at setting up Th!nk City production in the U.S. as early as 2010."

You may recall that in December these same advanced vehicle DOE loans were almost diverted to bailout old technology gas-guzzlers to the fury of new technology startups like Tesla , the XPCar and other electric car makers.

Fortunately that advanced tech funding ($25 billion) was saved. And Enerdel has applied for half a billion of that. So now it can be used as it was intended; to advance new low CO2 transport that can drive us into the post oil age.

Prius Powers Home in Ice Storm

Ice Storm Victim Improvises Prius-to-Home Energy Generator

A Massachusetts man - faced with no power in the recent ice storm, powered up the family Prius to create electricity: The hybrid car made enough electricity to run the essentials; the fridge, the lights, the TV, the wood-stove fan. During the power outage, it supplied 17 Kilowatt hours of energy to his home for three days.

How did he do it?



The Harvard Press described how the hybrid’s battery ran the house essentials for electrical engineer John Sweeney and family. He dug up an inverter which made 120v AC from 12v DC current and he wired it into the hybrid electric Prius, creating V2G technology on the fly.

V2G; vehicle to grid technology - is what will make it possible to reduce the amount of new power that we would otherwise need to add to the grid, because electric cars can act as rolling storage batteries to supply emergency extra electric power.

As such, V2G is of great interest to utlities and state governors seeking to reduce expenses and NIMBY issues associated with building more power stations. Vehicle to Grid technology reduces the need to build more power stations, by evening out grid loads; by swapping power back and forth as needed between electric vehicles and the grid.

But we don't call it V2G when it's your electric Prius powering your home, of course; the correct technical acronym is P2H; Prius2Home.

Last year the NYT reported on a similar case of another disaster victim powering his home in the same way; but this one employed his P2H power during a hurricane.
