Fresh Broccoli Pickle

Last week I tried a new pickle recipe adapted from "The Joy of Pickling" by Linda Ziedrich. It's a simple recipe, and after letting it cure for a week we tried it today at lunch. WOW! I meant to only eat one piece, but I had at least 10. If your kid likes pickles but doesn't like broccoli, give this a try. My 3-year old, Lucas, couldn't stop eating them either.

It is really, really, good. And good for you, too!

Here is the recipe:

1.5 pounds of broccoli florets
2 tablespoons chopped garlic (I used garlic scapes, of which I had a surplus)
1 tablespoon freshly grated ginger
1 tablespoon whole mustard seeds
two tablespoons fresh chopped cilantro
1 tablespoon olive oil
2.5 cups apple cider vinegar
2.5 cups water
1 tsp pickling salt

Pack a 2-quart jar with the broccoli and herbs.
Combine the vinegar, water and salt. Stir until the salt dissolves and pour over the broccoli.
Pour the olive oil into the jar.
Cap and refridgerate at least one week before eating.
Will store in the fridge for several weeks.

NASA does it again.


So. Just how smart ARE rocket scientists? Well, in a recent discovery that went unnoticed for 35 years, NASA has admitted that they have LOST the original tapes of the first moon landing. Oh, and, um, in typical American litterbug fashion, they left the camera, which also has data on it, on the moon.


How did they lose the tapes, you ask? Well, you see, they aren't positive, but they think someone probably recorded over them. Back then, NASA policy was to record over old tape reels in order to save money. And apparently someone didn't think that these were important enough to save. Who'd want that lame video? Anyone?


Gosh. Good thing there aren't any skeptics out there who think the moon landing was a hoax. That would really make their day.

How to build a Solar Dehydrator in 30 Minutes

Today I built a simple solar dehydrator in about half an hour, using a few household items. If this works well (and judging by my test run this afternoon it should) I will most likely build a more permanent one next summer made out of plywood, glass and screens.

What I used:

2 cardboard boxes (one large enough to hold drying racks, and one shallow one to collect heat)
Packing Tape
Black Non-Toxic Tempera Paint
Paintbrush
One Large Ziplock Bag, cut open (plexiglass or saran wrap will also work, anything clear to create a greenhouse effect)
A box-cutter
Scissors

First I taped up the large box. Then I cut a large door on one side, and small vent holes at the top opposite the door. Then I cut larger vent holes in the bottom of the box where my "heating box" will be attached.
Next I cut the top off the shallow box, cut off one side at a 45degree angle, and cut small vent holes in the opposite side. These small holes are where air will enter the box, become heated, and rise into the dehydrator box, drying fruits and veggies, and then rise out the top vent holes carrying moisture out with it.

I painted the inside of the heat box with non-toxic water based black paint and then I taped it very securely below the larger box, centered over the vent holes. I used the leftover cardboard from the heat box to make 2 triangular legs and taped them on the opposite side. This is a very stable dehydrator, despite being made out of cardboard!

Finally, I taped clear plastic over the heat box to create true greenhouse environment. Obviously, I would prefer to make this setup out of glass and wood b/c it is A) much more permanent and B) is less likely to off-gas fumes, but I am happy with this temporary setup for now. If it works fantastically well, I will definitely go on to make something more permanent... In the meantime, I am allowing the dehydrator to off gas for a few days before using it to dry food I will eat.

Drying food is great way to save your harvest -- few nutrients are lost, and no canning means they take a lot less space to store. No freezing means they use a lot less energy to conserve. And if you use a Solar Dehydrator instead of an Electric one, you also save a lot of electricity.

I am using drying racks which I have from my electric dehydrator, places on top of a metal baking rack to insure the air flows through up through them. I did not insulate my dehydrator, although many do... I am not sure it is needed in this climate, though I suppose in cooler weather it would be a good idea.

Up to my elbows in berries

OK. So I have made blueberry preserves twice already this season (the last batch used lemongrass and cardamom for spices, mmmm) and today, what did we do? We found another place to pick berries,at $2.00 a pound. Needless to say, we picked a lot! I am a bit preserved out for the week, so we made an upside-down blueberry cobbler (recipe below) and I am drying the rest of the berries in the deydrator. We began building a solar dryer today, but it's not quite ready yet -- maybe by next weekend!
Also among today's harvest was three pints of white mulberries from an old tree near our town green behind the bank. A bit weird to look at, but good in a cobbler (hey, when you're baking, might as well fill the oven, right?) Mulberries are not as sweet as other berries, so generally they need up to twice as much sugar in a recipe.



* UPSIDE-DOWN COBBLER *

2 Cups fruit
1/4 Sugar
6 Tbs Butter, Melted
3/4 Cup Flour
3/4 Cup Milk
2 tsp baking powder
1/2 tsp salt
Preferred Spices (optional)
Oatmeal or Granola (optional)

Preheat Oven to 350*F
Pour butter into 8" pie dish
Mix Flour, Milk, Baking Powder and Salt together, pour batter over butter in pan. Spices, Oatmeal or Granola are all tasty optional additions to the batter.
Mix Fruit and Sugar and pour over batter in pan.
Bake 30-35 minutes.

YUM-EAT!

Incandescent Bulbs Return to the Cutting Edge

This "enlightening" article in the New York Times caught my interest today...

When Congress passed a new energy law two years ago, obituaries were written for the incandescent light bulb. The law set tough efficiency standards, due to take effect in 2012, that no traditional incandescent bulb on the market could meet, and a century-old technology that helped create the modern world seemed to be doomed.

But as it turns out, the obituaries were premature.

Researchers across the country have been racing to breathe new life into Thomas Edison's light bulb, a pursuit that accelerated with the new legislation. Amid that footrace, one company is already marketing limited quantities of incandescent bulbs that meet the 2012 standard, and researchers are promising a wave of innovative products in the next few years.

Indeed, the incandescent bulb is turning into a case study of the way government mandates can spur innovation.

"There's a massive misperception that incandescents are going away quickly," said Chris Calwell, a researcher with Ecos Consulting who studies the bulb market. "There have been more incandescent innovations in the last three years than in the last two decades."

The first bulbs to emerge from this push, Philips Lighting's Halogena Energy Savers, are expensive compared with older incandescents. They sell for $5 apiece and more, compared with as little as 25 cents for standard bulbs.

But they are also 30 percent more efficient than older bulbs. Philips says that a 70-watt Halogena Energy Saver gives off the same amount of light as a traditional 100-watt bulb and lasts about three times as long, eventually paying for itself.

The line, for now sold exclusively at Home Depot and on Amazon.com, is not as efficient as compact fluorescent light bulbs, which can use 75 percent less energy than old-style bulbs. But the Energy Saver line is finding favor with consumers who dislike the light from fluorescent bulbs or are bothered by such factors as their slow start-up time and mercury content.

"We're experiencing double-digit growth and we're continuing to expand our assortment," said Jorge Fernandez, the executive who decides what bulbs to stock at Home Depot. "Most of the people that buy that bulb have either bought a C.F.L. and didn't like it, or have identified an area that C.F.L.'s don't work in."

For lighting researchers involved in trying to save the incandescent bulb, the goal is to come up with one that matches the energy savings of fluorescent bulbs while keeping the qualities that many consumers seem to like in incandescents, like the color of the light and the ease of using them with dimmers.

"Due to the 2007 federal energy bill that phases out inefficient incandescent light bulbs beginning in 2012, we are finally seeing a race" to develop more efficient ones, said Noah Horowitz, senior scientist with the Natural Resources Defense Council.

Some of the leading work is under way at a company called Deposition Sciences here in Santa Rosa. Its technology is a key component of the new Philips bulb line.

Normally, only a small portion of the energy used by an incandescent bulb is converted into light, while the rest is emitted as heat. Deposition Sciences applies special reflective coatings to gas-filled capsules that surround the bulb's filament. The coatings act as a sort of heat mirror that bounces heat back to the filament, where it is transformed to light.

While the first commercial product achieves only a 30 percent efficiency gain, the company says it has achieved 50 percent in the laboratory. No lighting manufacturer has agreed yet to bring the latest technology to market, but Deposition Sciences hopes to persuade one.

"We built a better mouse trap," said Bob Gray, coating program manager at Deposition Sciences. "Now, we're trying to get people to beat a path to our door."

With the new efficiency standards, experts predict more companies will develop specialized reflective coatings for incandescents. The big three lighting companies - General Electric, Osram Sylvania and Philips - are all working on the technology, as is Auer Lighting of Germany and Toshiba of Japan.

And a wave of innovation appears to be coming. David Cunningham, an inventor in Los Angeles with a track record of putting lighting innovations on the market, has used more than $5 million of his own money to develop a reflective coating and fixture design that he believes could make incandescents 100 percent more efficient.

"There's enormous interest," Mr. Cunningham said. "All the major lighting companies want an exclusive as soon as we demonstrate feasibility."

Both Mr. Cunningham and Deposition Sciences have been looking into the work of Chunlei Guo, an associate professor of optics at Rochester University, who announced in May that he had used lasers to pit the surface of a tungsten filament. "Our measurements show that the treated filament becomes twice as bright with the same power consumption," Mr. Guo said.

And a physics professor at Rensselaer Polytechnic Institute, Shawn-Yu Lin, is also seeing improved incandescent performance by using a high-tech, iridium-coated filament that recycles wasted heat. "The technology can get up to six to seven times more efficient," Mr. Lin said.

Despite a decade of campaigns by the government and utilities to persuade people to switch to energy-saving compact fluorescents, incandescent bulbs still occupy an estimated 90 percent of household sockets in the United States. Aside from the aesthetic and practical objections to fluorescents, old-style incandescents have the advantage of being remarkably cheap.

But the cheapest such bulbs are likely to disappear from store shelves between 2012 and 2014, driven off the market by the government's new standard. Compact fluorescents, which can cost as little as $1 apiece, may become the bargain option, with consumers having to spend two or three times as much to get the latest energy-efficient incandescents.

A third technology, bulbs using light-emitting diodes, promises remarkable gains in efficiency but is still expensive. Prices can exceed $100 for a single LED bulb, and results from a government testing program indicate such bulbs still have performance problems.

That suggests that LEDs - though widely used in specialized applications like electronic products and, increasingly, street lights - may not displace incumbent technologies in the home any time soon.

Given how costly the new bulbs are, big lighting companies are moving gradually. Osram will introduce a new line of incandescents in September that are 25 percent more efficient. The bulbs will feature a redesigned capsule with higher-quality gas inside and will sell for a starting price of about $3. That is less than the Philips product already on the market, but they will have shorter life spans. G.E. also plans to introduce a line of household incandescents that will comply with the new standards.

Mr. Calwell predicts "a lot more flavors" of incandescent bulbs coming out in the future. "It's hard to be an industry leader in the crowded C.F.L field," he said. "But a company could truly differentiate itself with a better incandescent."
