Is GEK A Modern-day Mr. Fusion?

March 4, 2010 by Mike Szczys 42 Comments

[Nanomonkey] spent the weekend building generators that run off of syngas. All Powers Lab produces Gasifier Experimenter Kits to convert raw material to energy. The kits use Gasification to make a “natural gas like” fuel from materials such as wood chips, walnut shells, construction debris or agricultural waste.

So is this the Mr. Fusion that powered the DeLorean? This Honda fitted with a GEK sure makes it look that way. But all joking aside, this looks like a great way to turn waste in heat or electricity. There’s tons of info on the site to dig through. The controllers are open source which would make it easier to interface with the Google PowerMeter when the system is used as a generator.

Google Unveils API To PowerMeter

March 4, 2010 by Mike Szczys 32 Comments

Google’s tentacles continue to wrap around every portion of our lives with the addition of an API for their PowerMeter software. The PowerMeter tool works with smart electricity meters to monitor and display power usage in the home. This will allow manufacturers (and hackers alike) to design new devices with the Google interface in mind.

We’ve got an old-fashioned power meter with a spinning dial and no blinking LED. This means we can’t monitor that blink to add our own PowerMeter interface. But if you do have an easy way to grab data from your meter you can design a home system that takes full advantage of Google’s tools.

Ok, who’s going to be the first to have their Google PowerMeter-compatible hack featured on Hackaday?

Cooling LEDs By Heating The Water Saves On Electricity

February 26, 2010 by Mike Szczys 32 Comments

[Matthias] swapped out his twin-tube florescent aquarium lights for LEDs. By running tank water through the aluminum LED mounts he’s transferring excess heat into the water in the tank, in turn saving some of the electricity that would have been used to heat the tank. Couple this with roughly 35 Watts saved by moving away from fluorescent tubes and he’s got a great energy-saving hack. The LEDs used in the last aquarium light conversion were cooled by heat sinks and fans. We’d love to see this concept incorporated into that design.

Steorn Orbo Motor Replica

February 21, 2010 by Mike Szczys 177 Comments

Reader [Hjhndr] ran across an interesting set of tests and wanted to know if they’re brilliant or just a load of bull. We’re not making the call on that, but the tests on a Steorn Orb motor replica are worth looking at.Keep in mind, people used to think the earth was flat and scientists of the time would have sworn up and down that’s the way things were.

The Steorn Orbo is a motor that generates more power than is put into it. At least according to Steorn Limited that’s what it does. An independent panel of scientists said otherwise a few years back but that didn’t stop the company from showing off the concept a few more times, most recently a showing in Dublin ended this month.

So anyway, [Jean-Louis Naudin] took what he saw from those demonstrations and built a replica. He’s made several papers about the principle as well as his testing available online. There’s a lot of math, a little bit of smoke and mirrors, and several videos. Take a look and let us know what you think in the comments.

Cannihilator Can Crusher

February 18, 2010 by Mike Szczys 49 Comments

This box will crush your cans and deposit them in the bin below. Branded the Cannihilator, [Jeff Walsh] built this with his two sons, [Jake] and [Ryan]. Early hacking eduction is important if they want their future projects to be regular Hackaday features.

The crushing power is provided by a solenoid pneumatic ram. As seen in the video after the break, the can goes in the door on the left, is crushed, then drops through a slot. [Jeff] had fingers and hands in mind when designing this and included a few safety features. The “crush” button is locate on the opposite end from the can slot, there is a kill switch to disable the solenoid, and a keyed switch to shut the whole apparatus down. A Basic Stamp 2 microcontroller handles the electronics with the help of a daughter-board to manage the load switching. This is a nice addition to the creative can crushers out there.

Converting A Miata To All-electric

February 15, 2010 by Mike Szczys 23 Comments

[Henry Herndon] converted a Mazda Miata to an all-electric vehicle. There’s a ton of great information in his archives, as well as a round-up video that we’ve embedded after the break. It’s interesting to see him implement two different types of Nalgene bottles as coolant reservoirs. The polycarbonate on the first shattered on him but the soft plastic replacement seems to have done the trick. The batteries add a lot of weight to the vehicle and he ends up refitting the suspension to compensate. [Henry] registered the vehicle with the state and now has a street legal EV of his own design.

Also worth a look is his post covering the 2009 Wayland Invitational. There as a large collection of electric vehicle conversions at the get together.

Things That Kill You, Hacked For Clean Energy

January 25, 2010 by Mike Szczys 26 Comments

Tobacco and E coli can wreak havoc on your body causing serious damage if not death. Some researchers from the University of California at Berkeley have found a way to take these potentially dangerous organisms and make them do our bidding. By genetically engineering a virus they have shown that the two can be used to grow solar cells. Well, they grow some of the important bits that go into solar cells, reducing the environmental impact of the manufacturing process.

Once a tobacco plant is infected with the altered virus it begins producing artificial chromophores that turn sunlight into electricity. Fully grown plants are ground up, suspending the chromophores in a liquid which is sprayed onto glass panels to create the solar cells. This types of creative solar energy production make us wonder if Thunderdome and the apocalypse are further off than we thought.
