    Energy Ball - Powered by the Wind, Sadly not Chi

    Energy Ball - Powered by the Wind, Sadly not Chi

    I’ve decided to expand the realm of the blog to encompass the second half of the title rather only focusing on LED-specific information. As much as I love LED lights (and could talk about them all day) I feel that broadening your horizons ultimately makes you a better, more well rounded person.

    I found this energy ball (unfortunately not the Kamehameha variety) while trolling through the interwebs, and it’s pretty, and pretty innovative. It’s basically a small wind turbine in a round configuration that provides increased efficiency and quieter operation than conventional windmill-style versions. It can operate in relatively low winds and can provide up to 15% of the energy of a typical Swedish family. For fat American’s I’d say cut that by 1/3rd, so maybe it can power 1/2 a PS3. The added benefit (or detriment depending on how you see it) is that it’s less likely to make spontaneous chicken (or bat) nuggets for you throughout the day.

    A turbine is a turbine is a turbine, you say? Well then I guess you you haven’t seen enough turbines. A large factor for the purchase of any consumer is form (vs. function), so having such a cute-looking windmill ball on the top of your house could make you the envy of your neighbors as well as providing a service to the environment. The other big factor is cost, so if they can make these at a good price point, I’d love to get a couple and put them outside. I would even name each of them after obscure DragonBall attacks.

    The Hoff as You’ve Never Seen….On a Liquid-Cooled LED LCD 1

    David Hasselhoff

    David Hasselhoff

    Hasselhoff at 130 inches. Screen size. Not the other thing. This must be what the epitomy of technological brilliance has brought us for all these years from Edison’s humble beginnings of the filament bulb. What you see here is an image from the world’s first 1080p (the highest consumer resolution out there) LCD projector powered with a liquid-cooled LED light bulb. As you know, LEDs have a lifetime of 50,000 hours, providing you 5.7 years of nonstop viewing.   That’s enough time to watch every episode of every season that the Hoff was in Baywatch back-to-back 315 times (yes I calculated) and still give you over four full days of bathroom and snack breaks.

    The projector spits out 600 lumens at 100,000:1 contrast ratio (meaning the blacks are are black-hole black and the whites are super-marshmallow white, the actual shade of the Hoff’s choppers), and is currently only a prototype being shown at the CEDIA 2008 Convention. Being the fact that it’s LED based also means that the power usage will be well below the 200-500W equivalent bulbs that are used right now, meaning that I could probably leave it on 24/7 for the next five years without killing my electic bill. Also with a lifespan dwarfing conventional bulbs by 10-20x, I would not need to replace the bulb for a while. FYI, projector bulbs normally cost at least a few hundred dollars which definitely makes me use mine sparingly.  No word on pricing, but but I would give my left…arm…for one when it comes out.

    Now THIS is an LED Light Bulb. 3

    A bulb-shaped LED bulb. Intriguing

    A bulb-shaped LED bulb. Intriguing

    Now why didn’t I think of that? Wait, I did. It’s our website logo. All they have to do now is put it into a leaf shape. Luckily this is just a concept because as beautiful as this LED light bulb looks, the light it outputs would only be coming out of the top hemisphere, if even. Normal incandescents can do it, because their element is large and the supports are made of glass. But we can always dream can’t we?

    "Multiple Self-Sustaining" LED Streetlights 3

    Things aren’t always what they seem. But sometimes they are. This Prisma streetlamp not only uses High power LED lights to shower the streets with it’s luminescence, but it’s interactive and pays for itself to boot. It’s supposed to be able to be controlled by a user, say for street fairs, which is pretty nifty, and even has solar panels(but then again what gadget nowadays DOESN’T have it) to help run the motor that turns the head assembly. Kind of defeats the purpose though if the main power for the light is still coming from the grid. The actual self-sustaining part is the fact that the vertical light can be pointed at various signs, banners, effigies of Jesus, or other advertising detritus to add an additional revenue stream to the mix. Not quite the supergreen product, but more like a light sea foam. Sadly (or perhaps happily), this is only a concept product, so you won’t be hacking a Batman symbol on the top dome any time soon.

    Light Bulbs with Fans?! 6

    I bet Thomas Edison never would’ve thought we’d end up making light bulbs with fans inside them when he invented the light bulb 100 years ago. That’s what I’ve been seeing more and more of lately both online and at the Las Vegas Lightfair I attended a couple months back (more on that in a future blog entry). Why? Because it’s a race right now for every manufacturer to make brighter LED light bulbs and grab the largest share of the market possible. So why the fans?

    To understand this a little better, let’s get into a little bit of LED bulb design theory. There’s three main components in an LED bulb:
    1. Chip/Die – This is the LED itself
    2. Heatsink – This is what keeps LED Chip/Die cool
    3. Optics – This is the lens that directs the light out of the bulb – giving you a narrow/wide beam of light

    CREE is the #1 US manufacturer(brightest) for LED dies right now. (See our LED Buying Guide for more information). We can pretty much assume the majority of manufacturers are using the same chip. What about the lens? As important as the lens is, you can only bend the light in so many ways, and the light output increase is only marginal using the same chip.

    So what’s the solution? Pack more LED’s into one place or drive them harder by putting more electricity through them. What happens when you do either of these and what’s the #1 killer of LED’s? Heat.

    So we need a way of keeping them cool. OK let’s just make a bigger heatsink:

    But now the bulb won’t fit in a traditional socket. “Doh”

    OK, what about a fan? “Aha!”. This will let us keep a small form factor, and keep the bulbs the same size.

    Sounds like a great idea at first but aren’t LED’s rated at 50,000 hours? That’s 17 years at 8 hours a day. Ever opened up a computer after 2 years and seen the amount of gunk the fans have picked up? Imagine the amount of gunk that they will pick up after 5 or 10 years? What happens then? Fan stops > LED overheats > LED dies. There goes $50 to $100.

    That’s my thoughts. I just don’t think LED bulbs with fans are the way to go. There’s no way they can possibly last 17 years unless we come up with a self-cleaning fan technology. I DID find a company that came up with a brighter bulb without a fan and am about to get samples of this bulb. Pictures to come…
    Anyone think otherwise? Anyone tried an LED bulb with fans?

    The Definitive Buying Guide for LED Light Bulbs 26

    What I’ve noticed lately is there’s a lack of information that can be found on the web about LEDs. Now there’s a ton of information online about LEDs in general, don’t get me wrong. But when it comes to LED lights specifically and what to look for when wanting to purchase them, the information is very sparse, and if it even IS available, it’s usually in a very technical format where you practically need an engineering degree to decrypt what the figures mean.

    Because of that, we’ve decided to create a guide of our own. It’s a guide that explains :

    • What LEDs are
    • How they work
    • Why they are better than compact fluorescents

    and most importantly,

    • What features you should be looking for when purchasing LED light bulbs

    The Great Wall of China – The LED Version 5

    Those crazy Chinese are at it again with another version of the Great Wall, at least from my perspective. I guess they’re in it to win it when it comes to grand displays to impress the rest of the world. Maybe this time they’re actually getting it right. This version is made up of LED lights and dwarves anything I’ve seen lately. Probably not the biggest I’ve EVER seen, but then again, it also isn’t an installation that uses half a million watts just for the sound system. No, this wall is so “great” because it is billed as a zero-energy fixture.

    The LED wall contains solar panels that harvest the sun’s rays during the day, and uses that energy to display a video light show at night. How completely perfect. It’s like the true circle of life. In theory, you could build one of these in the middle of the desert, away from any and all civilization, and play large-than-life size movies off of it. Take that another step further and I would LOVE to play some old school Street Fighter II on a deserted island. Although GTA IV would definitely keep my attention for a little longer.

    This is a one-off structure, so I don’t think they’re selling to the general public, but if you have to ask how much it would cost, you definitely can’t afford it. The new green buzzword of 2008 is “zero energy“. I’m already an adopter. I’ve had this solar-powered flashlight for years….

    An Energy-Efficient Streetlight for the New Age 0

    Back when I was a young’un and lived in the ‘burbs, there were times when I would be walking down the street or riding my bike alone at night. Sometimes as I was passing under one of those yellow-orange sodium streetlamps, they would, without any type of warning, suddenly turn off. Now having a wild imagination, I came up with two possible hypotheses for this occurrence. The first was that I was gifted with some magical power, or subconscious sixth sense, that interacts with the electrical field generated by the light, causing it to turn off. The other explanation was that a ghost or apparition was turning it off, as though sending me a sign that something bad (ala death and/or dismemberment) was going to happen. Generally, the latter idea would take hold and I would sprint the rest of the way back home.

    With these new lights, I may not have to worry about that ever again. Not only is it solar powered and using LED lights, it also works on a motion sensor. This makes a lot of sense in theory, since there’s no point in lighting up a path where there is no one walking down. My favorite feature is how it sits at 30% brightness, until something walks by and trips the motion sensor. So if all the technology can converge the right way for this to eventually become a reality, we’re looking at these lights being “off the grid”! Preposterous! Imagine all the strange places you could just put these things. In a dark corner of an empty park. On the top of a cliff. In the middle of the desert. As a prank on top of a dome!

    The design is very “trendy” which is always a benefit, but I’m wondering if this is still more of a proof-of-concept, than something that can be usefully implemented. From what I see, the LEDs being used are still the standard sized small LED’s that are used for keychain flashlights. Even used in an array, there isn’t enough power output to make the light as usable as it needs to be. The Eternaleds bulbs use more powerful LED circuits with energy output two orders of magnitude greater than the smaller bulbs. I worry that lights such as these will give LEDs the continuing reputation that they are not bright enough of not ready for consumer use. On the other hand, if the larger power LEDs are being used, then it’s also pulling more wattage, so there needs to be a brightness vs. power balance here.

    Still, it’s great to see things like these even publicized (even if it’s very obvious it’s still in concept stage), and I feel like this is the first step towards the golden chalice of usable energy-efficient lighting fixtures. Right now though, more realistic goals need to be made for LED application, or the technology needed to fulfill those promises need to be put in the hands of responsible designers and architects.

    Green Drinks NYC a.k.a. A Reason to Drink on a Tuesday 1

    I attended a Green Drinks Mixer last night (get it? Mixer? Drinks?….it was funnier in my head) and overall, had a pretty good time. Spoke with and educated a few people about LED lights, made some interesting contacts, and heard some good ideas about what’s going on in the green industry.

    I first heard about Green Drinks about two months ago, as I was participating in my favorite pastime of surfing the internet (of which I think I’m 84% of the way through it). I stumbled upon the site as I was looking for like-minded individuals in the New York area that shared a passion for the environment, and at the same time were progressive enough to know about new technologies and advocate them. On top of that, it would be a great place to network, and an AMAZING excuse to have a drink or two so early in the week. Not that you ever need an excuse to drink, mind you, but it does justify it to people better when you have a legitimate reason and that you’re not just a lush.

    So I’m running late and trekking over there through the biggest snowfall (which turned later into more of an ice-fall) in NY so far this year and get to the location that I had put in my PDA a month ago. There’s a narrow doorway with the correct address above it, but there is no one around, nor do I hear any people talking around the area. I’m thinking to myself “Is this one of those ‘uber-exclusive’ clubs that meet in non-descript locations that I keep hearing about? Well, that’s trendy.” I walk back and forth to confirm that the address is indeed correct. Two people come out of the locked door and I ask them “Is this where the Green Drinks meeting is?” She replies “Ummm….no. This is a residential building.” I’m flummoxed as I try to determine my next course of action. Luckily, I had the number of the location so I give them a call. They say that a lot of people had been coming by with the same problem, and the correct address is about one klick northeast of here, just off Houston St.

    So half-a-mile later, I get to the correct place at the Boucarou Lounge (which I realized I had been to before for a birthday party a year ago), and walk into a throng of people (easily over 200), packed like sardines, all chatting away and seemingly having a good time. I pay my $10 cover/donation, write my name on a name tag, stick it over my heart and mosey over to the bar for my first drink. I make light conversation with whoever is around me, delicately balancing the topics of interest between city life, eco-awareness, and steering clear away from anything related to politics or religion. There’s no better way to ruin the mood than to butt heads with someone about who they should vote for (That’s a tip for you though, if you ever want to “ruin the mood”, although “I think my friend is looking for me” works too.) I met a few individuals of mention – a Go Green Expo business manager (think I’ll have to pass on the booth until next year, but I’ll definitely be there as a consumer), a soon-to-be restauranteur looking to build his first green restaurant, and a guy from treehugger.com. You know, Treehugger…they’re like the Gizmodo of Green! I think working there, and being at a green event, makes him the automatic pseudo-celebrity of the night. It’s like going to a National Lunchmeat Convention and having your name be Oscar or Meyer.

    The most interesting people I met was a couple that had just bought a place in Harlem that they were renovating and making a green-certified 3 family condo. It was interesting to hear about all the criteria needed to have the building green-certified. Apparently, there’s 60 different criteria, ranging from disposal of building materials, to renewable bamboo floors, to window type, to lighting, that determine if you can get the green stamp of approval. All very interesting stuff. I read a little bit about that in the research that I had done, but it is pretty overwhelming the amount of information you need to know about it. He asked me about LEDs with the preconception that they’re not very bright (I dispel that myth on a daily basis) and was interested in seeing if they could be used for his house or a future project. They are looking for prospective buyers at the moment, so if you want a newly renovated green place in the city (which will no doubt save you a ton in energy costs), I can forward you their contact info. The other interesting thing about them is that they brought their daughter to the event as well (green family), and between the three of them – an architect, an author/photographer, and a graphic designer – they could start their own eco-design firm.

    These are the things that I learned :

    1. Wear a hat – If it’s snowing outside, and you’re going to be walking for an extended period, invest in some warm headgear lest you arrive at your destination with an ice helmet where your hair used to be.
    2. The Green Drinks NYC chapter is the largest Green Drinks chapter in the U.S. Also, someone told me that the Xmas party had about 500 people. Yikes.
    3. People are varied – there’s a lot of people, both interesting, and not so much that you will meet at a networking event. Filter out the wheat from the chaff.
    4. Networking is fun – especially meeting people for new ideas and activities
    5. Networking is hard – I thought i would talk to the whole room, or at least 50 people. I talked to probably about 10-12, and had a proper conversation with about 1/2 of them. There’s always next month.

    Overall, I had an enjoyable time, traded someone an LED flashlight for a bag of granola, and met some interesting people. It was definitely not what I expected, but I think I will attend again next month.

    Green Drinks is international, so I definitely recommend attending one in your area.

    Jeff’s Interview Tonight @ Green Health Live 1

    Tonight at 6PM PST, Jeff is doing an interview with Mark Ryan at Green Health Live. The URL you can see him at, AND participate with questions to ask him are :

    LIVE STREAM:
    http://www.thestream.tv/series.php?s=11
    WEBSITE:

    http://www.greenhealthlive.tv/

    Green Health Live is an online talk show (which is part of a larger video and entertainment site) that does weekly segments on how to live greener and educate people on green issues that they may not be aware of. I watched a few episodes (The Fish and Recycling episodes are good) and I like the style that they use, it’s not preachy or boring (as content like that *could* be in another person’s hands) and actually makes it fun to learn about how to do your part for the environment. It caters towards the general public which is really nice, especially if you don’t know a lot of the acronyms or technologies that are just thrown around nowadays. Personally, in this age of fast-food entertainment, if you lose my attention or go over my head for even a second, my hand is already on the back button to see the newest Youtube viral video.

    Of the episodes that I saw, Mark kept it interesting with his funny quips and comments, and co-host Carrie is a good bastion of knowledge on the medical aspect of each show. I think just the fact that he sports a faux-hawk while talking and interviewing guests is entertainment enough, but then again, I just have a natural predilection towards mohawks. Jeff will talking a little bit about the industry/business, but the focus of the interview will be on more informational topics such as

    • What LED stands for and how it works
    • Comparing and contrasting with conventional incandscent bulbs and fluorescent lights
    • Environmental impact and health implications of each
    • Cost and savings of LED technology
    • Interesting stories and thoughts

    It should be interesting to see how well Jeff does, and if anything, this will be a great resource for people that want to find out about or want a general introduction about LED lights. I’ll be posting the video up after it’s finished tonight. Stay tuned! Or better yet, watch the show and submit a question!
