Flash Laptop from Samsung

{mosimage}Samsung revealed a laptop with a 32 gig flash drive at CeBIT this year. Booting side by side with a traditional laptop with the spinning platters that we've all got, this thing was up and ready almost twice as fast.

Of course, twice as fast also translates to ten times more expensive. If it were in stores now, this drive would set you back about $900, a cost of $30 per gigabyte. Harddisk drives for laptops are currently closer to $2.50 per gig. So, even with the speed, the durability and the efficiency, Samsung has a ways to go before these drives go mass market.

 

Make a Battery a Flashlight

{mosimage}Falling into the category of “duh” inventions is this little device that pops on the top of a nine volt battery. Suddenly, the candle seems so obsolete! OK, this isn't a complicated post, but you gotta love when we're able to make something that is tiny, cheap, useful and efficient (not only in its use of electricity, but also in the use of materials.)

Pak-Lite says you'll get more than 20 hours on per charge on a nine-volt battery. Of course, if you use this thing on a battery that's not rechargeable, it becomes more a wasteful device than a marvelous toy. So, stock up on nine volt rechargeables and visit 9voltlight.com .

 

Dimmable Compact Fluorescents

Your real environmental commitment is tested most when you have to give something up. How many of us don't actually prefer riding our bicycles and eating delicious organic food? Organic, vine-ripened tomatoes. What a sacrifice! {mosimage}

I struggle most with making the very obvious and logically airtight decision to convert my household lighting over to compact fluorescent bulbs. Compared to incandescent bulbs, they use anywhere from 50-80% less electricity and last somewhere around ten times as long. A no-brainer.

But here's the problem: The light they cast is just plain ugly. Standard fluorescent bulbs emit too much yellow and blue, and not enough green and red. This limited spectrum is responsible for the horrible, sickly appearance of food in high school cafeterias, and the purply, poxed look of your face in truck stop bathroom mirrors.

What's more, standard fluorescents can't be dimmed. Who wants to eat nasty-looking food across from a sickly roommate under un-dimmable glaring lights in their own home? By show of hands?

Fortunately, technology advances. You can now purchase, on Amazon.com, dimmable, spiral compact fluorescent bulbs, which are at least somewhat color compensated to reduce the ugliness. We haven't tried them ourselves yet, but this EcoGeek is ordering some right now.

What's the point of eating tasty organic food if you can't enjoy it at just the right lumen level and with accurate color rendition?

Citizen Memory LCD

Take a good look at your computer screen and realize: Nothing is Moving. Yet, it is powered, constantly, as if it were a mobile display. E-Ink, the ecogeek's favorite display, has conquered this by only needing power to change its display while LCD screens have always needed constant power to maintain the display.

 {mosimage} 

No Longer! Citizen has created the Memory LCD , which retains its image even when turned off. Of course, this thing is a long way away from being a computer monitor. A good start though, and a good alternative to the slow refresh rate of E-Ink, if it comes to that (though don't ever expect this to be flexibile like E-Ink.)

If you're wondering, the picture here is a point-of-sale screen, showing that 500 grams of bananas costs 395 yen, and that the banana's come from Ecuador (and also where Ecuador is, just in case the consumer is interested.)

Organic LED Lights

Light bulbs are horribly inefficient at converting energy to light (touch one sometime, if you need a reminder.) They also force us into giving lights a very specific role in our homes. Light either comes from a lamp or a ceiling fixture. I know it doesn't seem all that annoying, since we've never lived any other way, but it's rather unfortunate that, in the day of iPods and 2mm thick flash drives, we still rely largely on bulky bulbs to light our homes.

{mosimage}So a team of scientists just developed a product that may solve these problems: The Organic LED. Two layers of phosphorescent diodes and one layer of fluorescent diodes releases white light much more efficiently than tungsten bulbs. These diode layers are only 10 nanometers thick and, when unpowered, are completely transparent.

We've just opened the door to lights that live inside our windows. Why have light fixtures at all anymore? As light stops coming through the windows (y'know, because of that whole sunset thing) the windows will just start producing their own light. Of course, only in rooms where you're currently spending time. I can't wait.

Of course, I'll have to wait, as Organic LEDs are currently very expensive and have never been mass produced. But it's good to hear that this century-old technology might finally meet its superior.
