exactly. wind power is intermittent - what's the storage capacity of the batteries? they apparently are expecting nuclear cloud cover and haven't provided solar power. and if a geothermal power plant will be destroyed, who's to say the wind turbine will survive? what's the water supply resource? sewer & waste management? how is the general store stocked w/ consumables (other than food)? if departure turns impossible, the residents best be really creative as to how to support their hobbies and keep their sanity - you can only stock & reread so many books. lotsa questions for the serious purchase contenders. seems to be a truly 'spare change' venture, like a novelty to boast about. and since i don't have the cash, not worth looking for serious answers. love the entertainment factor of the post tho!

and i LOVE the spotted lake post! i was so near but pressed for time, so couldn't even explore the wineries of the region (they weren't open after 9p or at dawn anyhow). but gives me a clue of the bodies of the vino i missed. minerality is acceptable in reds but not my favorite in whites! still, sounds like a good road trip side drive, on par with researching the extremophiles that can survive the yellowstone hot springs!

and maybe i can check for jobs & housing while i'm up there. speshly before the skies turn dark, which it's feeling more likely all the time w/ the new 'leadership' at the helm. being in the hills isn't the absolute safety zone i like to think it is. ;-)


Wind turbines also require maintenance and can be damaged. According to a wind energy trade journal 20% of wind turbines are down for maintenance or repair at any one time.

An Astronomical Flop

In 1985, Bary Bertiger, an engineer with the high-tech giant Motorola, had an intriguing idea: If a company could put enough low-orbit satellites in the air to attain direct access to the entire surface of the Earth, and use that network to support a satellite telephone system, then people could use the satellite phones to make calls to virtually anywhere in the world.

Image

This was very early in the cell phone era (Motorola had released the first one only a year earlier, in 1984), and people were becoming familiar with a problem that still exists today: if you’re too far away from a cell tower network your phone won’t work. With the proper satellite network, Bertiger figured, that problem could be overcome.

Image

Motorola chairman Robert Galvin gave Bertiger’s idea the go-ahead, and work on the project began in 1987. In 1991, it was spun off as its own company, Iridium LLC. Why “Iridium”? The plan was to put 77 satellites into orbit—and the element iridium is number 77 on the periodic table. (The number of satellites was later reduced to 66 for cost-saving reasons, but the name remained.)

Image

It took another six years to develop the technology necessary for the project, but in 1997, Iridium started launching its satellites. A year later, amid much fanfare—and after a $180 million advertising campaign—Iridium LLC started operations. “Iridium,” said the October 1998 cover story of Wired magazine, “may well serve as a first model of the 21st-century corporation.”

But it soon became clear that there were serious flaws in Iridium’s business plan. When Bertiger came up with his idea in 1985, cell phones were as big as bricks, nearly as heavy, and cost about $4,000.

They were owned by very few people, and worked in very few places. By 1998, the technology had progressed enormously. Millions of people owned small, sleek, pocket-sized cell phones served by nationwide cellular networks, and the cost had dropped to about $200.

Image

What was Iridium offering? A heavy, boxy phone that cost about $3,000. Cost to use it: from $3.00 to $8.00 a minute. By comparison, typical cell phone charges were already down to about 10¢ a minute. But probably the worst feature of all: Iridium phones didn’t work inside buildings, under trees, or inside cars without additional and expensive antennas. In order to work, the phones had to have direct line-of-sight access to a satellite. This, of course meant that their use was limited – at best.

Image

How much had Iridium spent in its 13 years of development? More than $6 billion. (Iridium had calculated that they would need a million subscribers just to break even. Impossible? No problem! Company analysts confidently predicted they’d reach that number in two years. The harsh reality: By August 1999—after nine months of operation—Iridium had just 55,000 subscribers. That same month, they defaulted on $1.5 billion in loans and filed for bankruptcy.

Image

The 12 years of development—and the $6 billion - were toast. At the time it was one of the largest bankruptcies in U.S. history, and it remains one of the most expensive technological flops ever. (Iridium’s single largest investor, Motorola, lost about $2.5 billion.)

Image

Aftermath: In 2000, a group of investors bought what remained of Iridium, including all of its 66 satellites—as well as several spares that had been launched—for $35 million.

Image

The company exists today as Iridium Communications, and they have about 600,000 subscribers, many of them in the U.S. military. And while the phones are smaller, lighter, and less expensive (Amazon sells them for about $1,000), they still don’t work inside buildings.

Why Does a Doughnut Have a Hole?

The doughnut didn’t always have a hole! These round, flat, fried cakes were once filled, with soggy centers. At least, that’s the way they were eaten when early Dutch settlers brought them to Colonial America.

Image

Then in 1847, a 15-year-old boy, Hanson Crockett Gregory, was in the kitchen of his Rockport, Maine, home watching his mother make these fried cakes. When he asked her why the centers were so soggy and uncooked that they gave him indigestion, she didn’t have the answer for him.

Image

So Hanson took some of the uncooked cakes and poked out the centers. This time when his mother fried them, they were delicious, for the hole let the dough cook more thoroughly, making the cakes much easier to digest.

Image

Today, doughnut makers put their dough into special machines that leave out the centers. The dough is then cooked in a vat of boiling oil until it is a puffy, crisp doughnut.

Image

And the house in Rockport, Maine, where Hanson Crockett Gregory was born, bears a plaque commemorating the day that a boy invented a hole!

Image

So, get yourself a cup of coffee, a hot chocolate or even a cold glass of milk and … well … enjoy!
