"The good news is with fairly simple improvements in packaging and shipping conditions, we could have a significant impact on improving queens and, in turn, improving colony survival," Pettis said.

I wonder what the additional costs would be.

NATURAL & ORGANIC BEEKEEPING METHODS / Re: Foundationless Hive
« Last post by iddee on February 13, 2016, 10:15:34 AM »
It's just my opinion, but when I hear a new beek saying "I want to go foundationless in 8 frame mediums, I hear:


""I want to learn to fly. I want to start as a fighter jet test pilot. Don't bother me with a Piper.""

I suggest learning the basics first, then try the peripherals.

For the guys that make their own hive boxes:

- do you finger/box joint the ends?  If not, has anyone had "separation" issues?  I have a Kreg jig and could use that for added support.
- Any particular wood species?  I know the standard is pine, but just looking for insight here.
- Any advice?
- I can just use runners for handles so I don't have to route out slots.

Thanks for any help/advice!

NATURAL & ORGANIC BEEKEEPING METHODS / Re: Foundationless Hive
« Last post by KPF on February 13, 2016, 09:51:56 AM »
Hello from Ohio, USA!

I am a "one year newbie" so please forgive me if anything I say is off base, crazy, etc....  I'm still learning. 

Having said that I am a newbie, I started last year with two hives (two deeps each) and two packages of bees.  One hive swarmed mid-summer, and limped by the rest of the year.  The other hive seemed pretty good all year.  Being new, I was afraid to open the hives up when it got cold, so I haven't been in the hives in a while.  I talked to a local beekeeper and he said it was okay to open.  As soon as we get a decent day, I'm going in.

With all that, I am pretty sure the swarmed hive is gone, just need to confirm.

I want to keep learning and trying, so I have ordered more packages for this spring.  I also have been reading "The Practical Beekeeper" and want to try Mr. Bush's approach.  I am looking at 10 frame Supers with a top entrance.  I also want to try foundationless frames so as to have natural size comb/bees.  One thing I noticed in my hives was Varroa, want to work on eliminating this occurrence...like everyone else

Going foundationless, is there anything "special" I need to know/do before I install the bees?  I know I need to put strips or some starter to keep the comb aligned in the frame.  Is there anything else, or do I just "dump them in" and let them do their thing?

Thanks for any help!

Eric, I'm the last person in the world to give you advice on this, since I have no experience with foundationless frames, but like you I am a 1-year newbie and I also have 50 Kelley Foundationless Frames in my garage that have yet to be used (though they will be eventually).  I also had two hives, one of which swarmed and peetered out and 1 of which absconded in early winter.  All I can tell you is reports I've heard from other members in my club, and some members find they have one hot mess in their hands when they first try foundationless. Now this may be largely due to beekeeper inexperience, and maybe you have to dive in and experience a few hot messes before you get it right, but if I were you, I'd hedge my bets. Maybe go partly foundationless (ie, put a few foundationless frames in between foundation frames) and maybe see if a local beek with experience in this area can be your mentor. You've already got Michael Bush's book, so that's a great place to start. In my opinion, which I reiterate, is an uninformed opinion of a 1-year beek, is that there is so much to learn about good beekeeping that going foundationless might be something you defer til a little later in your beekeeping career.  Then again, life is for the bold. The worst that can happen is you learn something, and that ain't so bad. Good luck!

Yes, but the first step in solving a problem is determining what the problem is! :wink:

HONEYBEE REMOVAL / Re: Swarm Catching Business Cards

Understood Idee...."beeproofing" beyond a 1 year guarantee of "same hive entrance  location" is the responsibility of the homeowner and the scenario you outlined has already been discussed and planned for ;-)

excellent info if somewhat alarming for those of us in the south ;-P

Thanks Jim, good info.

Purdue University News

WEST LAFAYETTE, Ind. ? Flower pollen could represent a boon for battery makers: Recent research has suggested their potential use as anodes in lithium-ion batteries.

"Our findings have demonstrated that renewable pollens could produce carbon architectures for anode applications in energy storage devices," said Vilas Pol, an associate professor in the School of Chemical Engineering and the School of Materials Engineering at Purdue University.

Batteries have two electrodes, called an anode and a cathode. The anodes in most of today's lithium-ion batteries are made of graphite. Lithium ions are contained in a liquid called an electrolyte, and these ions are stored in the anode during recharging.

The researchers tested bee pollen- and cattail pollen-derived carbons as anodes.

"Both are abundantly available," said Pol, who worked with doctoral student Jialiang Tang. "The bottom line here is we want to learn something from nature that could be useful in creating better batteries with renewable feedstock."

Research findings are detailed in a paper that appeared Friday (Feb. 5) in Nature's Scientific Reports.

Whereas bee pollen is a mixture of different pollen types collected by honey bees, the cattail pollens all have the same shape.

"I started looking into pollens when my mom told me she had developed pollen allergy symptoms about two years ago," Tang said. "I was fascinated by the beauty and diversity of pollen microstructures. But the idea of using them as battery anodes did not really kick in until I started working on battery research and learned more about carbonization of biomass."

The researchers processed the pollen under high temperatures in a chamber containing argon gas using a procedure called pyrolysis, yielding pure carbon in the original shape of the pollen particles. They were further processed, or "activated," by heating at lower temperature ? about 300 degrees Celsius - in the presence of oxygen, forming pores in the carbon structures to increase their energy-storage capacity.

The research showed the pollen anodes could be charged at various rates. While charging for 10 hours resulted in a full charge, charging them for only one hour resulted in more than half of a full charge, Pol said.

"The theoretical capacity of graphite is 372 milliamp hours per gram, and we achieved 200 milliamp hours after one hour of charging," he said.

The researchers tested the carbon at 25 degrees Celsius and 50 degrees Celsius to simulate a range of climates.

"This is because the weather-based degradation of batteries is totally different in New Mexico compared to Indiana," Pol said.

Findings showed the cattail pollens performed better than bee pollen.

The work is ongoing. Whereas the current work studied the pollen in only anodes, future research will include work to study them in a full-cell battery with a commercial cathode.

"We are just introducing the fascinating concept here," Pol said. "Further work is needed to determine how practical it might be."

Electron microscopy studies were performed at the Birck Nanotechnology Center in Purdue's Discovery Park.

The work was supported by Purdue's School of Chemical Engineering. The electron microscopy studies at Birck were funded by a Kirk exploratory research grant and were conducted by doctoral students Arthur D. Dysart and Vinodkumar Etacheri. An XPS measurement was conducted by Dmitry Zemlyanov at Birck. Other support came from the Hoosier Heavy Hybrid Center of Excellence (H3CoE) fellowship, funded by U.S. Department of Energy.
