If you’re in Tokyo tomorrow, make sure to check out Sony’s exhibit at the FC EXPO 2009. The company will display the newest version of its hybrid fuel cell, which contains a Li-on battery and a methanol fuel cell.

GoodCleanTech reports that the Sony Ericsson Greenheart Concept phone was spotted at a Sony event last week in Copenhagen. The phone will be an amalgam of “green” factors, including a bio-plastic shell, HTML-based manuals, a recycled plastic keypad and an energy-efficient charger that uses only 3.5 mW of power during standby.

Their paticipation brings the number of free patents available for use by anyone in the world to 69, more than doubling the original number.

Hosted by the World Business Council for Sustainable Development (WBCSD) the Commons was established in January this year by IBM, Nokia, Pitney Bowes and Sony in response to a growing dilemma among large businesses.

Unfortunately, we don’t have a comprehensive way to deal with E-waste. In fact, when the stations go ‘lights out’ on analog sets next year, there isn’t an e-waste program to handle the discarded TV’s. Currently, only Sony electronics has offered to take back and recycle old Sony sets. If old sets aren’t properly disposed of, we face cadmium, lead, beryllium seeping into the soil and contaminating our water supply.

According to the Take Back My TV campaign this is the largest government mandated obsolescence program in US history. The Sony announced their recycling campaign earlier this year in a release that noted the amount of e-waste is on the rise and the issue is becoming increasingly crucial as the FCC-mandated switch to all digital TV signals in February 2009 nears. The Consumer Electronics Association expects at least 30 million digital televisions to be sold in the U.S. this year alone.

I volunteered this year, on behalf of the O2 NYC, Green Options and my firm J. Ottman Consulting, at the inaugural Greener Gadgets conference on Friday, February 1st. On this raining day in midtown Manhattan I was happy to be inside the McGraw-Hill Conference Center on 49th Street. The conference was presented by research firm Marc Alt & Partners and design blog Inhabitat and brought out quite the group of designers, engineers, students, press and environmentalists. The speakers included the Head of Environment for North America at Nokia, Director of Product Take Back and Recycling at HP, and the Director of Corporate Environment, Safety, and Health at Sony, just to name a few.

I arrived at the conference about 9:30 am and was happy to notice as I walked in the doors, three disposal cans labeled “Waste, Recycling and Compost” and someone monitoring them. After I grabbed a stiff cup of coffee, in a mug as opposed to a paper cup, and checked my coat, I picked up my volunteer badge and headed in to hear the opening keynote speech. This speech, by artist and digital photographer Chris Jordan, was my absolute favorite of the day and I feel served to kick start the conference with the correct perspective of American mass consumption (something we all need in large daily doses).

Sony recently announced their current activity in developing a new bio-battery. The battery generates electricity from carbohydrates (currently sugar) and utilizes enzymes as the catalyst. The sample battery has proven to be able to output 50 mW, or enough to power a portable mp3 player. This is the world’s highest yet for a passive-type bio battery.

According to the Sony Press Release:

Sony developed a system of breaking down sugar to generate electricity that involves efficiently immobilizing enzymes and the mediator (electronic conduction materials) while retaining the activity of the enzymes at the anode. Sony also developed a new cathode structure which efficiently supplies oxygen to the electrode while ensuring that the appropriate water content is maintained. Optimizing the electrolyte for these two technologies has enabled these power output levels to be reached.

The newly developed bio battery incorporates an anode consisting of sugar-digesting enzymes and mediator, and a cathode comprising oxygen-reducing enzymes and mediator, either side of a cellophane separator. The anode extracts electrons and hydrogen ions from the sugar (glucose) through enzymatic oxidation as follows:
Glucose -> Gluconolactone + 2 H+ + 2 e-
The hydrogen ion migrates to the cathode through the separator. Once at the cathode, the hydrogen ions and electrons absorb oxygen from the air to produce water:
(1/2) O2 + 2 H+ + 2 e- -> H2O
Through this process of electrochemical reaction, the electrons pass through the outer circuit to generate electricity.

Since the battery does not require the user to do any mixing or formulating, the process is quite simple and it requires very little of the owner. But, each cm2 can only produce 1.5 mW in the first minute, so the battery has to be quite large. The current dimensions are 39×39x39mm- I don’t know how portable and functional it makes this object, but it is a step in an interesting direction.

The most applicable situation I see for this technology is for remote electrical generation necessities (which puts an interesting spin on neighborly sugar supply). For locations or trips that could not benefit from portable solar panels, sugar is a new alternative. As the design progresses and the technology is tuned, I am sure they will be able to come up with something on a more practical and portable scale.

Again, the question arises about genetically modified sugar due to increased demand of the material. Will we begin manufacturing it in the lab and what will this do to the sugar farmers across the world? These questions are always something to consider with the development of any technology using a finite, consumable resource.

It is although fun to imagine one day giving your cell phone a shot of liquid sugar when it starts beeping with low battery indication… Instead of cords, we will have IVs of liquid sugar lying about our apartment floor with a portal into our computer, our radio, our coffee maker…interesting.
