Summer Streets with New York Botanical Garden

Thursday, August 18th, 2011

Things on the BioBus were simply floral during a NYBG street fair on Saturday, August 13, 2011. The fair was held to celebrate Farmers’ Market Week, and it is safe to say that there was a large variety of produce offered by both NYBG stands and the actual farmers’ market. There, the BioBus’ staff (comprised of Dr. Ben, Nikki, Juliana, & Jordan) bought some beautiful bouquets hosting a variety of flowers…most of which were immediately brutalized by one Juliana (an intern at the BioBus) via scalpel. These lovely dissected samples were not wasted though! No, every and each sliver was carefully placed under the BioBus’s stereo microscopes under high magnification. Many children learned about the reproductive aspects of those flowers: where the specific organs are located and how a flower is pollinated. Some even got a short description of a plant’s vascular tissue, by yours truly. All the while, each person was given a sheet of paper containing visual aids with labeled arrows to aid them in their search for the plant reproductive organs.

“He’s so amazed; he’s trying to look at every part of the flower,” exclaimed an enthused mother, whose son was preoccupied with a bright red specimen.

These sheets even had spaces laid out for everyone, mainly the children, to draw what he had seen! Everything that was viewed, from the original flowers to their magnified samples were messily recorded and pasted onto the bus itself, and there they stayed until the event’s end.

The festival was a great success; as a man on a loud speaker announced, people were caught groaning that they had to leave. That made me snort. It was a long couple of hours that were extremely enjoyable.

BioBus: Why the Green Roof?

Wednesday, July 27th, 2011

Any Joe Schmoe who has visited the BioBus has had ample opportunity to learn about its ecofriendly attributes. However, one that is relentlessly overlooked by visitors is the green garden that resides at the bus’ fore-roof! Sure each person knows it is there, but many just mentally mark it down as an environmental bio-trend before making googly eyes at the fact the engine runs on cooking oil instead of gasoline. However, the BioBus’ green roof is more than just some pro-environmental fashion statement. Like all aspects of the bus, it also has a purpose; it helps filter the air and water, stabilize the BioBus’ temperature, block UV radiation, and prevent damage to that area of the roof.

I know this may shock some; how could something as simple as a rooftop garden do all of that? “Well, that’s simple,” says BioBus intern Jordan, “That isn’t just some garden planted on top of a bus, it’s an entire population of organisms—each living, breathing, and regulating like any other!” Well, Jordan has hit a large point in saying this. Each one of those plants acts as any autotrophic organism (light-absorbing plant) does. When one draws water and air into itself, it filters both through its body, releasing clean air and water vapor. By absorbing the sun’s heat energy, a plant on top of the BioBus evaporates excess water to cool down not only itself, but the BioBus too. Just like your skin, a plant acts as a barrier between UV radiation from sunlight and the people inside the BioBus. The legion of plants on the BioBus’ roof also acts as a barrier from harsh weather conditions and protects the section of roof that the plants cover.

As you see, every part of the BioBus is in place for a reason. No space was wasted in its construction, and even the most unremarkable aspects of it are useful in some way. This time, we discovered the uses of the BioBus’ undermined green roof. Who knows what other mysterious objects with cool uses can be found on the BioBus? Visit soon and find out for yourself!

BioBus—Vegetable Oil Filter

Wednesday, July 6th, 2011

It is true that the BioBus’ current engine runs on ecological fuel—fuel that harmless to the planet. It is also true that the bus can attain that fuel—vegetable oil—for free from any restaurant or fast food place. Don’t forget, though, that any oil that is donated to the BioBus is used, dirty oil! All of that dirty oil can’t get poured into the BioBus’ engine straightaway!

No, that oil contains copious amounts of food gunk, bacteria, water, and glycerin (a thick, colorless, and sweet-tasting liquid found in most beauty products) that would ruin any engine. Before using it, Dr. Ben has to separate the refuse from the vegetable oil.

Luckily, the BioBus owner has thought up an answer to this dilemma: a filter system. Said system, when I tried to research it, was a total mystery to me! In fact, Dr. Ben had to send me a diagram of the BioBus’ engine, only for me to stare at it blankly in confusion. Thusly, I asked Dr. Ben to explain to me just how the four-step filtration system works, and here’s how he put it:
“Step 1: When we suck grease out of any dumpster behind a restaurant, there is a strainer that filters large chunks (over 150 micrometers) of matter from the oil before it ever enters the bus.

Step 2: Between the dirty tank and the clean tank, there is a PRIMARY VEG FILTER that separates matter 30 micrometers or more—a marine-grade fuel filter.

Step 3: Between the clean tank and the valve assembly in the engine, the SECONDARY VEG FILTER separates water from the fuel, as well as anything 10 micrometers or larger—another marine-grade fuel filter

Step 4: There is a 10 micrometer water separating diesel fuel filter that is a normal part of the engine, which both the vegetable oil and the regular diesel fuel passes through—called the SECONDARY DIESEL FILTER.

Filters 1, 2, & 3 are ones that we put in, filter 4 is a regular part of the engine.”

His explanation, which was much easier to understand than the diagram was, gave me the impression that each filter is like different level of filtration. The first level is easiest to get through, because the stuff that gets stuck in it is the largest. Then, as the filters progress, more and more refuse is limited by the smaller filters. The vegetable oil at the end of the last filter is then guaranteed to be perfectly suitable for the engine!

Lasers on the BioBus

Saturday, January 30th, 2010

Just received a grant from the Awesome Foundation to build a laser tweezer on the BioBus so we can poke, prod, and pull cells and other cool stuff. Read more!
