Genetically-Engineered Organism Secretes Diesel

It sounds like science fiction but according to an article by Jay Lindsay of the Associated Press, A Massachusetts company has a patent on a genetically modified organism that secretes diesel fuel from water, sun and CO2 inputs. Here’s an excerpt:

Joule claims, for instance, that its cyanobacterium can produce 15,000 gallons of diesel fuel per acre annually, over four times more than the most efficient algal process for making fuel. And they say they can do it at $30 a barrel.

Normally I am opposed to genetically modified plants but this would appear to be a contained situation. Would it be a good thing for the planet if we had unlimited diesel fuel? I would guess that the CO2 would be net neutral whatever escapes the exhaust pipe would have had to have gone into the fuel initially – right?

I’m curious what other people think about this.

Skid Row Community Garden Gets SIPs

Novice gardeners + hot rooftop accessible only by many flights of stairs = perfect opportunity to use self irrigating pots.

Two master gardeners, Anne Hars and Maggie Lobl asked me to show them how to put together some SIPs (read more about what a SIP is here) for the Los Angeles Community Action Network, which works with homeless and low-income residents on skid row.  Hars, Lobl, myself and a bunch of folks from LACAN put together a few SIPs and planted vegetables on the LACAN rooftop. The plants are thriving in a space where previous attempts at container gardening met with mixed success.

Gardening, like all the ways we humans interact with our surroundings is all about context. If you’ve got soil, as I’m lucky to have, work with that first. But if you have only a sunny rooftop or balcony and/or limited gardening experience SIPs are a great tool. They almost guarantee success, which is encouraging for people who have never gardened before.

Pot o’ Goodness: Low, Low-Tech Water Conservation

Mrs. Homegrown here:

Continuing on the greywater theme, on big cooking days, when I’m doing a lot of boiling, steaming, soaking and rinsing, I collect all that used water in a big pot and take it out to the garden to water the plants. It’s full of nutrients, and won’t cause any blackwater* problems as long as you:

  • Use it immediately. It will turn foul if left to sit too long.
  • Pour it straight into the soil–don’t splash it all over edible leaves. Remember, soil purifies water.
  • Don’t use water full of food chunks or grease, as this will attract vermin and cause smells.

I know it’s only a little bit water that I’m saving by doing this, but to me it’s a symbolic act, almost a prayer. And heck, it hasn’t rained here since March, so every bit counts. Also, the plants really like the super-water. I think of it as a smoothie for them.

Another option is to re-use cooking waters as stock. This is something I don’t know much about. Sometimes I’ll take some nice bright green water leftover from steaming or blanching greens and use that to start a vegetable stock. But I’ve heard of people using pasta water as the base of soups. Have any of you tried that, or other techniques along those lines? Do tell.

And let us know if you have any quirky ways of saving water.

*What’s blackwater? It’s water which is dirtier than greywater, and therefore not usually recycled. Typically this is water coming from the toilet and the kitchen sink. Food particles from the sink turn septic quickly, and grease and heavy soap are not good for soil. However, our greywater guru, Art Ludwig, does say that kitchen sink water is nutrient rich, and suggests workarounds that allow sink water re-use, like grease traps or plumbing the sink so only the rinse water goes to the garden.

Greywater Fed Tomato Plant Takes Over The World

Homegrown Neighbor Here:

So a few months ago Mr. Homegrown helped me install a simple ‘laundry to landscape’ greywater system. Most of the plants that get watered by the system didn’t get much water before and were just barely surviving. There are several fruit trees, a rhubarb plant and an assortment of perennial herbs lining a narrow strip of land along the side of the house. Now, the plants getting fed by the greywater are going bonkers.

Last week the area became impassable it was so overgrown. The path along the side of the house had disappeared. I have the laundry water going to the sewer half the time because I don’t want to overwater. That and my roommate bought some non-greywater friendly soap. So I really only run one or two loads of laundry a week into the yard. But that has been more than enough.

Yesterday I hacked my way through the overgrowth and tried to train the rampant cherry tomato plant. The tomatoes are delicious. I eat them constantly when I’m in the yard and pawn them off on friends and family whenever I can. Still, there are tomatoes in areas that I can no longer get too. The tomato plant has killed my apple tree I think. I can’t see the apple tree under it anymore. The tomato plant is about eight feet tall and equally wide. It is reaching for the roof, using the poor buried apple tree as its support. I tried to photograph the madness, but it just looks like an indeterminable tangle and doesn’t really show what is going on.

But now I have reclaimed a path along the side of the house. If just an occasional load of laundry can provide such a boost to this little patch of land, I wonder what all of the other water used in the house could do. I would have to get rid of all of the low-water and native plantings and go tropical! It just goes to show how much water we use in our homes every day and don’t really think about where it goes. Eventually I would love for all of the water from our showers and sinks to go to the yard as well, but for now, the washing machine is creating a little tropical oasis and that’s plenty.

Scarlet Runner Bean Stew

Homegrown Neighbor here:

Apparently a block away, Mrs. Homegrown has also been having bean cravings. Maybe there is something in the air. Maybe its just that beans are hearty, filling, inexpensive and all around awesome. I happened to get my hands on a bag of dried scarlet runner beans from Rancho Gordo specialty beans.

Scarlet runners are a favorite garden bean as they are great climbers and produce beautiful red flowers. If you want to grow a bean teepee or need to cover a chain link fence, they would be a good plant choice. In fact, my neighbors, Mr. and Mrs. Homegrown, grow them every summer.
 
I’ve never had scarlet runners as a dried bean before. But having lived in co-ops in Berkeley for many years, I am pretty experienced at cooking dried beans, other legumes and whole grains.
When it comes to dried beans I almost always do the overnight soak method. To soak beans overnight, simply place your beans in a large pot. Rinse them and pick out any stones or broken beans. Fill the pot up 3/4 of the way with water and let soak overnight or for at least five hours. After their soak you may need to add more water. The beans can soak up a lot. Then cook on medium to high heat for about an hour. Test a bean. How done you want your beans is rather subjective. If you want to use them in a salad, you may want them a little more firm. But if you want to make refried beans, they need to be extra soft. Just taste and see what you think. I like my beans nice and soft but not falling apart.
So to cook the scarlet runner beans I placed them in the 3 quart enameled pot that goes with my solar cooker, filled it the rest of the way with water and let the beans soak overnight. The next day I admired the fat, swollen beans. I threw in a few bay leaves and put the pot in the solar cooker around 9 a.m.. I arrived home around 4 p.m. and my beans were done.

They are big and meaty, but still rather bland. I’m going to eat them for dinner tonight and this is what I’m going to do to flavor them: I’ll keep the pot liquor (the water the beans cooked in). In a separate skillet I’ll heat some oil and saute onions, garlic, maybe a few pieces of celery then add some mushrooms. I really recommend cooking the onions and mushrooms in butter for extra flavor. But since I’m making tonight’s dish vegan, I’m going to cook them in coconut oil. Then I’ll add the cooked onions and mushrooms to the beans on low heat. Then add 1 -2 teaspoons of ground cumin and a dash of cayenne.Yum.
