Geothermal Energy

A recent comment got me searching:

Are there no geothermal energy plants that produces electric in Kauai ?

Greetings from Iceland ;)

Velkominn! Eftir því sem ég best veit, nei. (Welcome! As far as I know, no.)

But there’s a map for that:

GeothermalKauai

These maps were produced in 2000 by GeothermEx, a “geothermal exploration, development, and operations” company based in the Bay Area of California. Not much to see there, especially when compared to the active volcano on the Big Island. On the following map, the red areas are “high temperature resource areas,” and the numbers associated with them are the “probability of high temperature” (high enough for geothermal exploitation, I assume).

GeothermalBigIsland

There is a 30 MW geothermal plant in that red area, near the town of Pahoa. It provides 20-25% of the electricity for the Big Island. However, it is not without controversy: as carbon-free as the electricity is, they do have to clear the rain-forest (and the endagered species it supports) wherever they drill, and there have been issues with a hydrogen sulfide gas leak back in the 90’s. Plus they actually drilled a hole down to magma at one point, though there is apparently no danger of it gushing out.

So the hot spot on the crust has moved too far from Kaua’i, about 330 miles (530 km) from the summit of Wai’ale’ale to Kilauea. Kaua’i is an extinct volcano and there is no heat left underneath. What I find interesting in that first map is that they show the estimated location of the caldera and major rift zones on Kaua’i. I’ve never seen such a map, and I’m wondering whether the location of those features is based on previous research or some new interpretation of data.

However, Google found a brochure about geothermal in Hawaii with a map that includes some shading on Kaua’i. Even though it seems to show the location of the geothermal plant on the Big Island, none of the other shaded regions match the scientific maps, so I think this is “only for illustration:”

And here’s a connection between Hawaii and Iceland: the University of Hawaii School of Ocean and Earth Science and Technology had an expedition to the underwater Reykjanes Ridge in the summer of 2007. They have an expedition website with geologic maps of Iceland and lots of photos of their research cruise.

PS: There is geothermal energy tapped here in California, a lot of it: 13,000 GWh or 433,333 times as much as in Hawaii, yet it only supplies 4% of state usage. I’m not sure the numbers are comparable, however, because that includes such things as 160 degree water used for heating a school (still good though).

Eo e Emalani i Alaka’i

I just realized that the Eo e Emalani i Alaka’i festival is this weekend in Koke’e. I don’t usually mention events on this blog (since I don’t write often enough) but this is one of my favorite events on Kaua’i, and I urge anyone who can make it to go see it.

The festival consists of a reenactment of Queen Emalani’s visit to Koke’e in 1871. During that trip, she hired a guide from Waimea and traveled with her retinue up the rim of the Waimea Canyon, through the forest, across the swamp to the Kilohana lookout. When the travelers were tired, they stopped and Emalani’s friends danced hula to entertain her.

For the reenactment, people are chosen to play the royal court, they ride on horses into the big Kanaloahuluhulu meadow in Kokee, and various hula halau (troupes or schools) from throughout the state perform for the Queen and the public.

Rain or shine:

We’ve gone many times, and even our young daughter absolutely loved it. She figured out herself that the lady in the beautiful dress on the horse was a “princess” and that everyone came to her party to dance for her (sounds like the Nutcracker, another favorite). There are some booths with arts and crafts too, and afterwards you can play in the meadown, explore the forest on the nature loop, or visit the little (and free) Koke’e museum.

It all starts at 10am, and the queen makes her entrance at noon. However, do plan to arrive before noon, as parking is limited and you may need to walk from one of the temporary parking lots they set up along the roads nearby. Also bring lawn chairs or blankets, umbrellas in case of rain (also good for shade) and sunscreen in case of sun (you burn faster at 4000′ in the tropics). I also suggest bringing your own food. They have limited food sales there (maybe it’s improved by now), so we usually get bento boxes from Ishihara’s in Waimea to eat on the lawn during the show. The semi-official website is at kokee.org, and the website of one of the hula halau has some great photos.


If you do wander off during the breaks in the program, be sure to come back at the end when the queen rides away as all the dancers come out to wave goodbye. EmalaniFestivalGoodbye
EmalaniFestivalHulaHalau This festival feels very special and very moving to me; it is more than just a reenactment. The Hawaiians had an oral history, so repeating the stories, chants, and hula is how they would to commemorate (which means “remember together”) significant events. So in a sense, this event is actually a continuation of the Hawaiian culture and tradition, not separate from it. It draws you in and makes you part of the continuum.
Incidentally, there is also a guide in the reenactment, and while he doesn’t do much other than escort the queen and handle the horses, this must be one of the few events in the world that celebrates the role of the mountain guide. EmalaniFestivalGuide

I also think it is also a very unique celebration. Where else can you see colorful, authentic, heartfelt hula with a true cultural context in a such a beautiful outdoor setting? Only on Kaua’i.

A Brief History of Kalalau

A reader recently asked me about the Hawaiians who lived in Kalalau valley before and the “hippies” who live there now:

I know Hawaiians previously lived in the valleys, but after it became illegal, they left. Or did they?

I’m not certain about exact dates, but here is a rough timeline. What’s not exactly clear is when and how it became illegal to live in Kalalau.

Historically, Hawaiians lived in certain valleys that could support them (Kalalau was the biggest, but also Honopu, Nualolo, and maybe a few people in others). They created terraces and grew either taro in irrigated plots or dry-land yams, in addition to fishing. Much of the valleys were deforested, and I’m not quite sure what they did for fuel (I never thought of it before, and I’ve never heard anyone speculate on that). I know they had treacherous trails down from the forest in Kokee, so maybe they carried bundles of wood down.

In any case, archaelogists estimate up to 2000 people could live in Kalalau, which I find plausible. I suppose that was before 1800. After the subsistence agricultural society had been displaced by the commodities and merchandise-based economy brought by the missionaries and whalers, farms were abandoned, especially in the hard-to-reach valleys. I think they must’ve still been inhabited in the late 1800’s, as demonstrated by the famous story of Koolau the leper who hid out in Kalalau with other lepers who didn’t want to be sent away.

By the 1900’s, I think the smaller valleys (Nualolo and Honopu) were abandoned. Kalalau was accessible by trail and had more water, so I think people still lived there. The land was sold to one of the big families on the island (not sure of the details, but it may have been the Robinsons), and it became grazing land for cattle. So there must have been a few people running cattle there, probably living seasonally with a few fruit trees and vegetable garden. Incidentally, they used to drive the cattle in and out on the Kalalau trail, sometimes losing one over the edge–and I’m not sure if they also got the cattle in and out by boat–seems like a lot of trouble to me.

I met a local in Kalalau who claims his Aunty was the last person to live in Kalalau, and I suppose that was in the 30’s or 40’s. Sometime after that, it became a state park, and parts of the Kalalau trail became nature reserves (though hunting is still allowed in many areas, so it’s not just tourists on the trail). In the 50’s and 60’s, an African-American doctor retired/gave up his practice and became known as the hermit of Kalalau, in the pre-hippie era. In the 70’s, the hippies were all over Kauai, especially at Taylor camp at Haena, and I’m sure many of them moved to Kalalau when the camp was shut down.

I’m not quite sure of the circumstances, but I suppose 20-50 people lived in Kalalau quasi-permanently over the 70’s. I don’t know if it was tolerated, ignored, or just plain unknown to the park administrators. Nor do I know if they more or less left by themselves or were forced out. I think by the 90’s, there were less permanent residents, probably 10-20, with various free spirits adopting it as home for months at a time before moving on. When I first went in early 2000’s, I think there were less than 10 real residents, with a few people migrating in and out over the seasons. Some of them live by growing weed for sale, as well as collecting welfare, and carrying supplies into the valley.

Does anyone live along the Na Pali? Aside from the legalities, could they?

I do know that over this decade, the park service has totally cracked down on the residents, evicting nearly all, some by force and commando-style. But I get the impression that a small core remain, both hiding up in the furthest reaches, and also grudgingly allowed by the park rangers. They sort of position themselves as care-takers, not trashing the place and keeping out or reporting the inevitable whackos who show up and try to move in. The local guy I met didn’t live there himself, but use to boat in and out regularly to camp, hang out with the residents, resupply them, and carry out trash. I think he was tolerated as well, up to a point.

There was another local of Hawaiian descent who would live there for weeks at a time and claimed to be a caretaker of the spiritual locations in the valleys (old heiau). The park service cracked down on him pretty hard, because he was openly flaunting the permit system and authority of the parks, even though he was doing no harm.

Because Kalalau was historically an agricultural valley, there was one experiment of allowing a caretaker to go in and replant a taro and vegetable patch, sort of as a token gesture to the Hawaiian community. I saw the patch growing once when I was there, but I never saw the people. I don’t think the park continued the experiment, because I’m fairly sure it does not sanction anyone living there now.

So there you have a short overview. Moving into Kalalau is certainly possible, people do it all the time even today, but it tends to be more limited and mostly under fear of being chased by rangers. The rangers come in by helicopter and chase down any “residents” they can catch, so they’re really cracking down, or at least appearing to do so.

A recent comment also asked about the famous library of Kalalau:

I was wondering…I have heard there is a “library” in the valley….a bunch of paperbacks under a tarp….Does it exist and if so… how do you find it. I love to spend time reading…finding a great spot, soak up the beauty and share it with a book but they are HEAVY and if there are books to borrow I would love to do so. What can you tell me?

I believe it was the hermit of Kalalau mentioned above who started the library in the cave he lived in, which I gather was the first sea cave. I imagine that the various people living in the valley after him either kept his books or started new collections. When the rangers raided the valley these past years, I heard they dismantled whole encampments, and that probably included some books. But I don’t know if there was still a big library or whether it survived.

When I was there last year and talked with some of the residents, it sounded like there were still books around, but whether that was the main library or just little collections, I could not tell. What I do know is that it’s not a public library with borrowing privileges. You would need to meet and befriend one of the locals before you would have a chance at receiving any book they might have. And I doubt you would get to see or browse the “library” itself, if it still exists; I think they are much more particular about their hiding places now. However, once you break the ice with them, they tend to be very generous, so who knows what you will find.

Generous or not, it would still be a nice gesture if you brought a book with you and offered it to someone there. Paperbacks aren’t that heavy and are usually small enough to pack on the trail. That might be the best way to open the doors to the library. (Then again, if everyone who reads this and takes a book in, the residents are going to start wondering what the big deal is.)

No Joy From Felicia

What is it with the hurricanes starting with F lately? Two years ago, it was Flossie, and right now Felicia is bearing down on Hawai’i.

More seriously, this is the first time since I have lived on (and off) Kaua’i that I’ve seen Kaua’i in the predicted path:

First the good news: Kaua’i is on the edge of the predicted path, which I interpret to mean less of a chance of being hit. However, storm direction is perhaps the hardest to predict. More encouraging, and hopefully more accurate, the hurricane is predicted to weaken into a tropical depression, with winds under 40 mph (60 km/h), as shown on the graphic above.

The bad news: my family is travelling to Kaua’i without me next week. It looks like they’ll arrive before the storm, and I won’t join them until after it passes. So it looks like they’ll have to put up with lots of rain and avoid camping.

I guess the silver lining is that we’ll be on the island to clean up around our house that we have rented out. The last big storm blew some shingles off, so I might have to go up on the roof to glue them back down.

Update: you can follow Felicia’s progress at the NOAA/NWS Central Pacific Hurricane Center.


Update for posterity: after targetting Oahu, then Maui, and causing much news reporting, Felicia finally weakened before passing through and making lots of rain but no significant wind on Kaua’i. Here’s the last forecast from the Pacific Hurricane Center, on Tuesday, August 11. They stopped tracking the storm at this point. NOAARemnantFelicia

The Other LIH

Having a home on Kaua’i but living in California, I’m in the strange position of almost being forced to vacation there. No, I’m not complaining. But it is enlightening to see the island through the eyes of a visitor again, refreshing even. And that includes going through the whole process, and expense, of booking a trip to from San Francisco to Lihue. In searching all the different travel websites, I ran across an interesting tidbit.

When searching for flights, I usually memorize the airport codes of where I want to go, so SFO to LIH. One of the travel websites I use is kayak.com, and it gives me the choice of going to Lihue or Lihir Island, Papua New Guinea (LNV).

While I admire the global awareness of the algorithm, it seems pointless to offer a location that 99.9999% of the travelers don’t want, and for which they can’t sell me a ticket anyways—SFO to LNV returns no results in the end. But being curious about other islands, I had to see where this was:

GoogleMapsLihirIsland
Source: maps.google.com

And Wikipedia shines through again, with some good information about the place, as well as the local culture. The indigenous name of the island is Niolam, it’s also volcanic in origin, about half the size of Kaua’i, and half as high. Interestingly, it is home to “one of the last remaining cargo cults on earth,” and even if you think you know what a cargo cult is, I encourage you to read that link about them because it gives you one of those rare insights into the human mind.

Lihir Island also produces geothermal energy, so it’s volcano is still active unlike Kaua’i. Also unlike Kaua’i, it has one of the world’s richest gold mines, which I find odd for a volcanic island (but I’m no geologist). More interestingly, the Wikipedia article asserts that all the land still belongs to matriarchal clans. I hope that means they don’t have the development issues and real-estate speculation that we do on Kaua’i.

Even though this was a bit of a chance encouter, the islands seem more similar than not, and maybe could learn something from each other. Kaua’i certainly could strive for more renewable energy, and I’m sure there are a lot of Hawaiian activists who wish the land was still in the hands of Hawaiian families.
