Shameless Plug for BeUtilityFree

Take the idea of energy sustainability and apply it to what are probably your largest energy uses: your home and car. That’s the approach of BeUtilityFree. Take a look at what we do at www.beutilityfree.com. (I’m the webmaster as well as a renewable energy installer, so I’d love to hear feedback on what you think of the site at brett_s AT BeUtilityFree.com.)

The grand plan is to start out by reducing the amount of energy you use through replacing your current fixtures and appliances with more efficient ones, or designing your new home with efficiency built right in. Then you can buy a much more affordable renewable energy system that will cover your modest needs.

Once you own your means of production, you start getting paid back through avoiding the ever-rising cost of fuel, selling renewable energy credits for your production, taking tax breaks and utility incentives and maybe even selling excess energy.

We sell energy-efficient appliances and lighting and renewable energy systems like solar electric, solar hot water, wind power, hydrogen cogeneration and ethanol stills. We’ll design renewable energy systems, install them or just sell the components to those who have the skills to set them up themselves.

Our special, can’t-find-them-anywhere-else items are Nickel-Iron batteries, the Superior Solar Storage Tank and our 3″ and 4″ column Ethanol Stills.

We are hoping to unveil a few exciting things in the near future. Among them are:

• A turn-key ethanol plant. Just put feedstock, water, enzymes and yeast in one end and watch the fuel pour out the other. We’re currently testing enzymes for cellulosic production so that making ethanol can be as inexpensive and sustainable as possible.
• A Purchase Power Agreement plan that lets anyone get solar energy from their rooftop without any up-front investment. We’d retain ownership of the solar system and sell you the energy at a rate lower than the utility company’s.

If we can get everyone to pump renewable energy into the grid or unplug and make their own energy sustainably, we’ll have taken a huge step toward getting this climate problem licked. And if everyone owns the source of their energy, we can all get out from under the thumb of the utility company and the US Oil War Machine and get back to making a poistive difference in the world.

I just read in the current issue of Discover magazine that there are two new capacitor gadgets out on the market. A bike light and a cordless screw driver. I am REALLY excited about the screwdriver. It’s made by Coleman, and has a recharge time of 90 seconds. Seriously, that is unbelievable. I have spent so much time waiting for hand drill batteries to recharge that it makes me edgy just writing about it. 90 seconds! Instead of a battery this driver has an ultracapacitor inside which, like all capacitors, has the ability to take a charge very quickly. You can learn more about it at flashcelldriver.com

Charges in 90 seconds! That’s right… 90 SECONDS!!!

The bike light is pretty cool too. It has a capacitor in it, and gets its charge from a magnet attached to the wheel of your bike. Every time the magnet goes by it allows the light to generate a little electricity. There are two models, one that flashes, and one that stays on continuously while you ride, and for a short time when you stop. Learn more at reelight.com

I should point out that I have not seen either of these devices in person.  I am relying on Discover magazine and the manufacturer’s websites, but even so, I’m pretty impressed.  Capacitors are still not useful for larger, more power-intensive machines like hybrid cars, but researchers are working on it.

When I buy office products, I always try to buy paper products that have the highest recycled content I can find. Initially, I couldn’t find anything that had recycled paper in it at all, but over the years recycled paper products have become more and more available, and in steadily higher percentages of recycled content. The problem is that they are usually more expensive, and sometimes way more expensive.

On a recent trip to Staples for office paper, not only did I find 100% recycled paper (100%!), but it was actually cheaper than the other stuff. That is so great. I honestly never thought I would see this happen. Sometimes you have to look at the little things in order to see progress, but I would say that this is actually huge.

This is a weird time for tech, and isn’t the tiny stirling engine cute? The article is here.

The problem is it’s not too efficient to split water into the stuff (and oxygen of course). The Department of Energy’s goal for efficiency by 2010 is 10%. Now comes along QuantumSphere Inc. They have figured out a way that with nano-particles (ones they developed) they can increase the surface area of the anodes used in conversion and they’ve got it working at a 85% efficiency. Keep in mind, it’s is working, with a theoretical goal of 96%.

Kevin Maloney, president, chief executive officer and co-founder of QuantumSphere says “Our nanoparticle-coated electrodes make electrolysers efficient enough to provide hydrogen on demand from a tank of distilled water in your car.” …. Oooo, Detroit will love this.

Now is this a pipe dream? No. Things are coming out very soon. They’ve got a battery using these particles that will increase alkaline cells power by 320% (more power in ratio to nasty chemicals) that will ship in the 2nd half of this year!. They have and are doing lots of cool things here, read this article to get the rest of the scoop on things like hyper efficient Metal Hydride batteries.

One last thing to get excited about. Their goal was to make a thimbul full of these nano particles. But they are way ahead of schedule. They now have a plant that can make TONS of the stuff!

Read the fascinating  article here.

The engine will be more efficient as the difference in temperature between the heat source and the heat sink goes up, reaching 60% at about a 600-degree-to-room-temperature differential. Achieving such a temperature is no problem for parabolic mirror solar thermal collectors, which can easily reach 800 degrees.

Johnson is hoping that a variation of his heat engine could generate electricity from the heat of an internal combustion engine or even from human body heat! Sounds like The Matrix could come true!

Nanolsolar Inc. has been talking big lately about making a leap in solar panel technology that will drop the cost to under $1 a watt. The current standard for solar panels has been hovering around $4 a watt (wholesale cost) for a while.

Well, on December 18th Nanosolar announced their first shipment of solar panels that are profitably produced at $.99 a watt. Batch 1 went to a solar electricity utility in Germany and residential panels won’t be available for at least 12 months.

The big jump down in price was due to their new no-silicon method of printing a copper-indium-gallium-diselenide nanoparticle ink onto a metallic film substrate with inkjet technology. And, fortunately for us, this new type of panel will maintain the current 15%-20% standard of efficiency found in crystalline silicon panels!

Because of their ease of production and short-circuiting the current silicon shortage, I think this announcement will herald in the age of a flood of cheap solar power for everyone. And with the advent of new batteries for home energy storage like the nanosilicon wire lithium-ion cell (technical paper for the true geek here) in development now, the power grid may just become one more way to date films and old photos.

DARPA, the US military’s Defense Advanced Research Projects Agency,  sponsored a rally in November of 2007 offering a $2 million prize to the company or individual who could navigate an urban setting the fastest with a driverless vehicle.  There were a lot of SUV’s in the race (you need a lot of room for all the sensors and hardware, apparently) and one monster truck.

The winning vehicle, coming in at a blistering average speed of 14 mph, was outfitted and programmed by a Carnegie Mellon Team.  It took more than a dozen lasers, radars and cameras to make the AI truck capable of following the rules of the road, parallel park and avoid obstacles, and over 500,000 lines of code to process the information.

Unbelievably, the race had only one collision:  a 10 mph bump between two vehicles.  I wonder how that compares to human-driver accident rates?

I know we’re all waiting for the day we can don our jet packs and wingsuits for the morning commute, but this AI car idea is a pretty good concept for diverting our attention until then.
