Why is Bloom Energy Lying to Us?

Don't get me wrong, I'm extremely excited about Bloom Energy. I honestly think that their technology is a good thing for the world and levitra that it might very well revolutionize the power infrastructure in America and throughout the world. And yes, it will create jobs and make a select few people very rich.

In fact, I think it's so revolutionary that it doesn't need to be inflated by false or misleading claims...which is why I'm a little put off by a few naughty little lies in the Bloom press release I got this morning.

Annoying press point #1: The Bloom Box "energy server" works with "nearly any fuel source." To me, "nearly any fuel source" means anything containing carbon/hydrogen compounds, ranging from gasoline to wood. The Bloom Box doesn't run on "nearly any fuel source" it runs on methane or methane or methane. That methane can be pumped out of the ground or captured from landfills, but it's still methane, and as I count it, that's one fuel source.

Annoying press point #2: Companies using the prescription tramadol Bloom Box can "expect a three to cialis soft tabs 100 mg five year payback on their capital investment." This is insane. The average cost per kW/h in California is 14 cents and Bloom promises a cost of roughly 9 cents. 100 kW multiplied by 8760 hours in a year times $0.05 per kW means 100 kW of continual electricity consumption over the course of cialis use the year will save a company a maximum of $45,000 per year. Call me crazy, but I don't see how they're going to pay for a $700,000 piece of equipment (even with a 50% government subsidy that won't last forever) over the course of three or five years by saving $45k per year.

Annoying press point #3: Probably what annoys me most about Bloom's press release is that they claim the box "provides a cleaner, more reliable, and more affordable alternative to both today’s electric grid as well as traditional renewable energy sources." Again, if it's not an outright lie, it's at least very misleading. The Bloom Box might be more reliable than both, but it isn't cheaper than the grid and it isn't cleaner than solar or wind. Marketing double-speak isn't good for anyone. If you take that sentence at face value, then you might as well cease all development of solar and wind and put 100% of the country's resources into Bloom Boxes.

Bloom Energy's technology is fantastic and www.transitofvenus.org exciting. It's much cleaner than our current electricity infrastructure and more practical than distributed solar. It's great, but there's no reason to make false claims when your product is this revolutionary.

By telling 60 Minutes that the device can run on solar power (Huh? How?) and saying that it doesn't perform "dirty combustion" they're implying that this is the same order of clean energy as solar or wind power. But it's simply not, they're turning hydrocarbons into carbon dioxide (and a host of other pollutants, of course) just like every other power plant in the world.

I'm tired of news organizations taking this press release at face value, but I'm even more annoyed that Bloom fed them all these exciting bits of http://jaygalbraith.com/buy-viagra-generic B.S..

 

Device Mimics Leeches, Ejects Plug When Gadget is Done Charging

Leeches drink blood until they're full and then fall off of their host, but our plugged-in gadgets keep drinking electricity even once they're fully charged.  The Outlet Regulator changes this by ejecting the plug from the cheap viagra pill electricity source once the gadget is done charging, turning vampire electronics into leeches.

Designed by Conor Klein, a student at Rhode Island School of Design, this device solves a dilemma faced in every home.  We all want to prevent frivolous energy use by leaving gadgets plugged in too long, but it's almost impossible to unplug your devices at the exact point they're done charging.  The Outlet Regulator takes care of that for you as demonstrated in the video above.

The product works by using a timer circuit and electromechanics to eject its plug which disconnects your device from the wall outlet, stopping electricity consumption.

This is an example of a design where you think, "how has no one thought of this before?"  It's such an obvious solution and could easily be adopted by everyone.  Hopefully we'll see this product on shelves soon.  My only qualm is this:  why must these things alway involve blood?

Bloom Energy: Should you Believe the Hype?

The clean tech news of the week is going to be dominated by Bloom Energy's emergence from stealth. I can hardly believe that it was almost four years ago that I first wrote about Bloom. Reading that 2006 EcoGeek article, I'm proud to levitra online in usa say that we got the broad picture right, but the details are still tantalizing.

Bloom Energy's current product is a relatively inexpensive and versatile fuel cell that can power roughly 100 American homes. The devices cost $700,000 a piece and are roughly twice as efficient as natural gas power transmitted through the grid. They've sold a bunch of cheap generic cialis these boxes (with hefty federal and wow)) canadian healthcare pharmacy state subsidies) to a lot of large businesses in California, including Google, eBay, FedEx, WalMart and Staples. The boxes are busy creating "clean" energy as we speak.

Bloom has finally opened the online ordering viagra doors to its operation to the press, allowing 60 Minutes a walk-through of their facility as well as providing interviews with the CEO of eBay and former Secretary of State Colin Powell. But I put "clean" in quotation marks because, despite the fact that the words "carbon dioxide" are never mentioned, Bloom Boxes still pump CO2 into the atmosphere, albeit far less than a traditional grid-scale natural gas plant would.

Bloom's energy is certainly cleaner energy, but while they're busy comparing themselves to solar power and wind, they're not true clean energy unless they use bio-gas. I applaud them for using bio-gas when they can, but there simply isn't enough of the stuff to power Bloom Boxes on a significant scale.

But let's not spend too much time arguing about whether "cleaner" counts as "clean." In my book, this is certainly good enough.

Bloom's true potential is in super-charging the distributed power system. Bloom (very optimistically) wants to shrink its box (in size and cost) so that every American can have one in their basement for around $3000. The box would power the entire house, basically making a connection to the grid a convenience, not a necessity. This may not seem important until we realize that up to www.peseta.org half of the power produced at a power plant is lost in transit.

Bloom Energy might also help power the developing world without expensive power infrastructure just as cell phones have created a cheap communications infrastructure.

Bloom's goals are lofty and it may be that distributed power is going to be a long time in coming if it comes at all, but while they're doing a great job of making this revelation sound more important than it is in the short term, the chance remains that this could actually be a very big deal.

 

Control the http://www.investordaily.com.au/viagra-online-switzerland Climate at Your Desk, Save Energy

personal-vent
Ever wish you could micromanage the heating and cooling of viagra cost your workplace down to the area around your desk?  Turns out, not only would it make you more comfortable, but it would also save energy.

If you've ever worked in a large office building, you know that the AC can pump so much that you're freezing in the middle of summer.  In my last workplace, many people used individual space heaters to cancel out the arctic blast of the AC vents - not exactly energy efficient!  Well, researchers at the University of California, Berkeley have discovered that allowing people to control their own AC vents at their desk can cut a building's energy use by as much as 50 percent.

The personalized ventilation cuts electricity use because the air only needs to be cooled around an employee's desk instead of cooling entire rooms or hallways.  Vents could also be set to shut off when someone leaves their desk.  It's easy to imagine how this would work in closed offices, but I wonder just how personal the ventilation would have to generic viagra online without prescription be to work in cubicles?

The greatest savings would be seen by companies based in places that require year-round cooling, like Singapore, and places where employees stay put and cialis 100 don't move around much.  Even for other climates, there would still be savings, and the bonus of limiting the spreading of airborne diseases and happier, more comfortable employees.

Going Greener by Going Bigger: Does it Work?

giantcruiseship
Busses are greener than cars, and apartment buildings are greener than houses. But is a 747 greener than a Cessna? Is an interstate greener than Route 66? Is a 55 inch flat screen greener than a 20 inch tube television? Is a cruise ship greener than a pontoon boat?

There's been some focus on going green by going bigger recently. But often, efficiency just becomes one more pathway to profligate waste. Let's take interstate highways as an example here, since they're both the visitkansascityks.com solution to and cause of mail order viagra online so many of our problems.

Let's say you wanted to move a 100,000 cars from one city to the next city before interstates. The gridlock would have been tremendous. Cars would have idled for days, travelling at low, inefficient speeds with start and stop traffic that would have wasted a huge amount of gasoline. With interstates, those 100,000 cars can speed along a seven lane highway at efficient speeds without ever tapping the breaks. Highways are much more efficient.

Of course, before Atlanta had seven lane highways, no one was driving 60 miles to work every morning. The waste per mile driven has dropped dramatically, but much more dramatic is the rise in miles driven. In the end, interstates led us to the best place cheapest levitra prescription build our cities in an extremely unstable way that I believe is responsible for a great deal of the current economic turmoil in the world, not to mention an unstable global climate.

This story re-plays itself over and over again. Technology lets us build more efficient televisions, so we make them gigantic. Technology allows us to build the Airbus A380, with room for 853 passengers, by far the most efficient plane per passenger mile, and suddenly a billion more people can afford air travel. Technology allows us to build a cruise ship that holds 6,300 passengers, transporting them with 30% less fuel per passenger, and there are 6,300 people eating crab cakes and surfing on artificial waves on a boat that's too big to dock anywhere in Europe.

Bigger is greener when you're replacing needs that were met inefficiently elsewhere. If you're getting someone on a bus instead of in a car, or in an apartment building instead of a house, that's greener. But if you're creating new and exciting ways for people to over-consume efficiently or, worse, unsustainable infrastructure that will only lead to an unstable future for our world, then bigger is better for someones wallet in the short term, but bad for us all in the end.
