Speaker 1: Welcome to spectrum the science and technology show on k a l x Berkeley, a biweekly 30 [00:00:30] minute program bringing you interviews featuring bay area scientists and technologists as well as a calendar of local events and news.
Speaker 3: Good afternoon. My name is Brad swift and I'm the host of today's show. Our interview is with [inaudible], a fifth year mechanical engineering and Applied Mathematics major at UC Berkeley, who along with Kimberly Lau, launched the human power gym project. After conducting a feasibility study, they are attempting to design and prototype [00:01:00] an elliptical exercise machine for the UC Berkeley recreational sports facility that will generate electricity. Rather than consume it, the generated electricity will be put back into the electrical grid. The project began in the summer of 2009 Maha g talks about her enthusiasm for the project and the challenges to make it a reality. Maha and I are joined by Rick [inaudible] for the interview. This interview is prerecorded and edited. [00:01:30] Maha, could you please explain the project you're working on currently?
Speaker 4: Okay, so I'm working on a project titled The Human Pirate Gym Project. It's part of the Berkeley Energy and Sustainability Laboratory in the mechanical engineering department. And the goal of our project is to harness human power from exercise machines currently in the recreational sports facility or the RSF at UC Berkeley. And we're hoping to retrofit and 28 elliptical machines to harness human power and send it back to the electric grid and also work an energy education [00:02:00] campaign to improve energy literacy among the members of the RSF and people who frequent the facility to give them a better idea of sustainability and energy.
Speaker 3: How did that idea bubble up for you and the group you're working on this with?
Speaker 4: So I'm working on this with a graduate student named Kimberly Lough in the Mechanical Engineering Department under professor at Gugino. We came across it separately. She came across the idea when she's working out in the RSF, seeing all these people burning calories and you know, exercising so much, they must be expending a lot of energy and there must [00:02:30] be a way to harness that. And then I came across the idea because I was reading up about, um, there's a project harnessing children's power to pump water up out of the wells. And in African villages they create like a, a carousel where kids can play on and when they spin around the carousel they're actually pumping water up into a tank. And so I thought, well if kids run around and harness all this energy, why can't we do something like this and the gyms across the u s
Speaker 3: and much power do you
Speaker 5: expect [00:03:00] to be able to generate from all this?
Speaker 4: So unfortunately it's not a lot of power. Um, the RSF uses on the order of 1.5 million kilowatt hours a year and energy consumption and by other things like air conditioning or where's all that go? So actually it's not air conditioning cause we live in a bay area. We don't actually have air conditioning and the RSF cause it stays relatively cool. It's definitely for heating and air circulation and ventilation. And then a good chunk of it goes to lights and actually [00:03:30] powering treadmills, believe it or not. So if we haven't retrofitted 28 elliptical machines, it would harness about 10,000 kilowatt hours a year, which is enough to power a small house but only 1% of what the RSF needs to run its daily use. The treadmill is actually account for about 12% of the energy use at the RSF and not a lot of people know that. So part of our project, we're trying to encourage people to use elliptical machines or other self powered machines that use less power that but give comparable workouts [00:04:00] according to fitness trainers and the hopes that maybe they'll switch over to more ellipticals and the treadmills can be replaced in the RSF cause they actually acquire. I think running on a treadmill for about an hour requires as much energy as doing a load of laundry, washing and drying.
Speaker 5: How did the project come together in terms of getting an off the ground funding, all those things.
Speaker 4: So two years ago I am part of the UC leads program, which is, I forgot what it stands for, but it's some type of scholarship program at Berkeley that encourages summer research. [00:04:30] So I was funded by them to do a summer research project two years ago and I contacted fresher ag Gino with this idea saying, hey, I'm funded, can I work in your lab with Kimberley? She's really awesome. Wants to work in this project. So the UC leads program funded me for that summer and they've also funded me to continue researching in the fall and of that year, fall 2009 so we researched the feasibility of this and tried to come up with some energy estimates on how much energy we could harness, how much that would cost, what sort of things would need to be in place [00:05:00] to continue actually with the retrofits. And we actually published a paper in a conference and a spring of 2010 with the American Society of mechanical engineers. And after that we started applying for funds through the Green Initiative Fund, the Sigmas I m research honors society and the Chancellors Green, the chancellor's Green Fund cacs, I believe it's called the Chancellor's Advisory Committee for sustainability. And so with all those three funding resources, we have about a little over $17,000 [00:05:30] currently to actually go ahead and build these prototypes and get going with the retrofits at the gym.
Speaker 4: Can you talk about your, a conference paper anymore. So what does it, what was it about? So our conference paper was published in the American Society of Mechanical Engineers Conference on Energy Sustainability in May of 2010 and it just talked about our feasibility study on the RSF detailing how much power could be harnessed from the RSF, what [00:06:00] percentage of power consumption that accounted for. And it also detailed sort of how long it would take to payback such a system. And it also looked at the light life cycle assessment of the system and life cycle assessment basically means you take into account all the energy required to make the components that you'll be adding to the system and then take a look at how long it would take to payback the co two emissions related to that energy that was put in. So I think we estimated that unfortunately it's relates [00:06:30] to at savings of only a thousand dollars a year in energy consumption because energy is so cheap out here. But if we made CO2 emissions, the metric instead of dollars, the system would pay itself off in like two to three years of CO2 savings. If we assume that the energy generated at the RSF no longer needs to be generated by say PGNE and then taking into account how much CO2 is required for those few components that we have to add to each elliptical. So that was a much less bleak outlook.
Speaker 5: [00:07:00] Did you draw on previous attempts to do the same thing?
Speaker 4: So we redid a lot of research and a couple other gyms across the nation have retrofitted elliptical machines specifically to harness human power. And we talked to them and we talked to, there's a company called rewrap that actually does commercial retrofits and they approached the RSF also saying that they could do the retrofits before I came onto the project and we talked to those jams and I actually had a chance to visit one of them in [inaudible] at Oregon state. And [00:07:30] for some reason they didn't seem to be completely happy with the setup. For one reason or another, they didn't think it was producing as much energy as they thought. And so based on those interviews I had done with gyms across the nation, we decided to try and come up with our own retrofit. Also, cal poly has done a retrofit of their gym facility and are harnessing power from ellipticals in their own method.
Speaker 4: And the gym users there are really, really excited about it and really enjoy it a lot more than people at Oregon State for instance. So that's kind of why we're trying to go [00:08:00] ahead with doing it ourselves. Um, based on interviews and research from other gyms, definitely. And are only the ellipticals being used to generate power. Currently they're the easiest to tap into because they have an onboard generator that will convert your human power movement into resistance, electrical resistance that you feel when you're working out. So it's really easy to tap into them, just remove the resistance mechanism and instead put in something like an inverter to convert the DC power [00:08:30] you're generating to AC power. That can be used and sent back to the grid.
Speaker 5: When the cal poly success, was there any attempt to collaborate with them?
Speaker 4: We did approach them and ask them for collaboration, but I believe they are, have, they have some sort of patents on their devices now and it's very proprietary and so they're not, they're various hesitant to work with us and so if we create our own solution we're hoping to be much more open about it and sort of spread it around to any universities who want to do this on their own. Jim, [00:09:00] because we've had such a hard time contacting other people for help that we want to make sure it's easier for others.
Speaker 6: You are listening to spectrum on the KALX Berkeley, we are talking with Mar Haji, but the human power gym project of which she is a founding member.
Speaker 5: What's been the most challenging aspect [00:09:30] of the project?
Speaker 4: I think definitely recruiting people for the project because we've seen so many people come and go last year in our teams that has been really hard to get anything done. Um, we really need people who are skilled in electronics and mechanical engineering and unfortunately I don't have a very big electronics background myself and since I'm graduating in December, I have a lot of requirements that I need to meet and I can't give my all to the project as I could two years ago. So it's been really hard to find people who are as motivated or as determined about the [00:10:00] project to go ahead and finish it up and follow it through and hand it off and I, so that's been a big, big challenge I think.
Speaker 5: Is that something that you want to do? Do you want to recruit people what he was attempting to do in that vein?
Speaker 4: Yeah, we definitely want to recruit people because it's going to take a lot of work and a lot of minds to prototype one elliptical and then expand it to the entire gym. And like I said, since I'm graduating in December, I definitely want to hand off the project to other people to sort of conduct follow up [00:10:30] research. Like okay, if we put these ellipticals and generate power, do people actually learn from this? Do the energy literacy rates go up, do treadmills get useless. There's a whole host of followup research that could be done and hasn't been done yet and definitely has a potential of being published and presented around the nation I think.
Speaker 5: So are you mostly interested in recruiting other engineers and how would they sign up?
Speaker 4: So I'm interested in [inaudible] definitely recruiting um, upperclassmen engineers but also [00:11:00] people who have experience in signage and education. Cause I know, I don't know how best to reach people or get the knowledge disseminated about all the energy sustainability going on in the RSF. And that would definitely be helpful. And if anyone's interested they can just email RSF energy@gmail.com we'd be happy to have them on board.
Speaker 5: All right. Any of your current efforts documented anywhere of Wiki or mainly list or anything like that?
Speaker 4: So we have a webpage, hpg.berkeley.edu [00:11:30] needs to be updated for the past couple months. But generally a lot of our documents are there and we also have a [inaudible] website for all the members of the project. And that's how we communicate for papers that need to be read or budgets they need to be updated and that kind of thing.
Speaker 5: Do you know if, uh, there are sort of commercial efforts in this too, like commercial? Uh,
Speaker 4: so besides outside, outside universities, I guess so universities are really unique in that their gym [00:12:00] facilities are open for so many hours and frequent, so many users. So unfortunately Jim is like 24 hour fitness even though they're open 24 hours, don't see as much throughput of people or patrons that, um, university of do. So there hasn't been a huge push and they're at that direction. I believe there's a handful of them that use at least the re-roof technology. And there's a couple of gyms that are like, I think there's one gym in Hong Kong that's created some type of something called like a human dynamo where four people will bike on [00:12:30] the sort of combined system and move their hands at the same time and that will generate a whole lot of power for the gym. But aside from that, then not much that I know, it seems like a natural for a gym setting is to make it competitive somehow. I know both Oregon State and University of Oregon did retrofits and they sort of had a competition like who can create the most energy. Um, and we hope when we actually retrofit the gym to involve some sort of LCD panel that reads out which elliptical is [00:13:00] generating the most energy, you know, compare it across the gym and everyone can see, oh no like I gotta be 12 like my friends over there or something. Yeah.
Speaker 4: What's been the most unexpected thing that's happened in the project? So finding an elliptical machine was really hard. We originally thought that it was this elliptical machine floating around and so to haul on the sixth floor that no one really had, no one really knew who it belonged to. So we thought we'd use that for our project. We had [00:13:30] took a while to track down who the professor was who had it laying around and he gladly donated it to our project. And then when we took it apart, we found out that its internal mechanism was completely different than those used at the gym. It was using less electrical resistance like modern, most ellipticals use in was using more mechanical resistance, um, something much more like a recumbent bicycle. So we were like, well if we prototype on this system it's really not going to be compatible with anything in the gym.
Speaker 4: So then we had to contact the gym and try [00:14:00] and track down elliptical that way. And luckily they were after a couple of weeks or months, like everything fell together when we finally got it transported. And transporting those big things is also huge hassle from the RSF all the way down to attra very hall on North side on the social outreach part of it, the behavioral aspect of the project. What's been the challenge there to get that up and running? Um, so we conducted a survey of all the members of [00:14:30] the RSF and I believe something like five or 600 responded, which was great. And they, we post questions such as how much energy do you think x, Y and z machines use? Um, to get an idea of how energy literate people are about the machines at the RSF. And so we have a good base of where we think people could have their education, energy education improved. It's just a matter of figuring out the best way to actually do that. So as a mechanical engineering major, unfortunately I haven't [00:15:00] had to deal very much with energy education or engineering education and we could definitely use people on our project who know perhaps more like the psychology of a situation. Like definitely some sort of analysis on where people move in the RSF and where's the best place to place these things and how can we make them as interactive as possible to increase awareness, stuff like that.
Speaker 2: [inaudible]
Speaker 6: you are listening [00:15:30] to spectrum on k a l x Berkeley. We are talking with Maharaji but the human powered gym project of which he is a founding member.
Speaker 2: [inaudible]
Speaker 5: are there any key things that you're learning in doing this that you might not have learned if you hadn't been involved in this project?
Speaker 4: Definitely like in Berkeley engineering for the first three, three and a half years [00:16:00] of your educational career. It's very theoretical and this project has given me the advantage of doing something on the side that's much more hands on and applications of my learning at Berkeley. So that's been really awesome. And then working with other people on a project and just knowing how to work in a team is not something that people teach you in class either until you get to the higher level project-based classes and engineering. So that's been really great. And uh, working and collaborating with people, not only in the mechanical engineering department but the directors of the RSF to [00:16:30] TGF and other funding agencies and Co working together to get all that going is like intense. I can only imagine what professors have to go through to get grants written and proposals and then get the actually get that money and use it for their projects. That's been kind of like a mini
Speaker 5: many experience with that. How much time do you estimate you spent working on a project?
Speaker 4: Well, I've been working on it since summer of 2009 and I work anywhere [00:17:00] from five to 10 hours a week on it. I think pretty consistently with the exception of last summer and this summer because I've been away doing other internships and research projects. But every time I come back to Berkeley it's like, all right, got to get on. I gotta get going again.
Speaker 5: And have your summer internships where you haven't been working on the Human Powergen bin and sort of related fields?
Speaker 4: Yeah. Last summer I got the chance to go to Oregon State University and do, uh, an inner and study on the interaction [00:17:30] between wave energy devices in the environment, studying what types of organisms might colonize the environment. Cause I hadn't really, really been looked at. And then this summer I got the chance to go to MIT and study, um, fluid dynamics in the ocean engineering lab there. So starting to get a feel for the field and both on the west and the east coast and getting ideas of what professors doing what. So that's been really great. Yeah.
Speaker 5: So for this project, you're probably not going to get completed by the time you graduate and if you're able to hand it off, [00:18:00] would you be involved in trying to get additional funding to make that transition happen?
Speaker 4: I think at the moment we haven't used much of our funding because we've had a lot of setbacks and getting ellipticals and getting team members. So depending on the stance of the project in December, we would definitely, depending on if we've used a lot of our funds for prototyping or we're still waiting to get people on board to start prototyping, that would probably influence whether or not we apply for more funding. But I mean [00:18:30] more money's always great cause right now the funding we have budgeted, we'll only retrofit 14 of the 28 ellipticals. So if we are to consider doing all 28 we definitely need to look for more funding. I'm just sort of hesitant to do it right now because we don't actually have anything prototyped at the moment and no real product to show before we apply for more funding.
Speaker 5: What is it that you like about engineering? What drew you to engineering?
Speaker 4: So actually one thought I wanted to be a film major for a really long time [00:19:00] and then I went to a summer program just for like fun. I was like, okay, I'll get out of the house for a month, uh, in mechanical engineering. And they had us like take apart part printer, take apart a blender and like build these little like out of the box robots. You're just like screw a few things in the other and put a battery. And I think just the whole idea of like building things and taking things apart sort of amazed me. And I was always like really good at puzzles and math and so it was like, oh this is like way more fun than making movies. [00:19:30] So that's sort of what drawn me to it.
Speaker 5: Has Your work on this project given you a better sense of how what you want to do going forward?
Speaker 4: Yeah, definitely. It has encouraged me to look more into alternative forms of energy. That's definitely what I want to do in the future. Unfortunately, it's made me disheartened about human power cause going into the project I thought, Oh yeah, we can just retrofit all the ellipticals and then power the entire gym. We use so much power on a daily basis that that's not [00:20:00] feasible so definitely opens your eyes onto how much power we consume every day and I think this project has been a great stepping stone into the world of alternative energy and I hope to study something like ocean energy and ocean energy extraction for graduate studies in school.
Speaker 5: Thanks very much Maha for coming on the show and sharing your experience with us.
Speaker 4: No problem. This was awesome. Thanks

Speaker 3: Now three news stories that caught our attention. Genetically engineered canola growing outside of established cultivation [00:25:30] regions across North Dakota. A study published by the online journal plus one reports the genetically engineered canola endowed with herbicide resistance have been found growing outside of established cultivation regions along road sides across North Dakota. These escaped plants were found statewide and account for 45% of the total roadside plants sampled. Furthermore, populations were found to persist [00:26:00] from year to year and reached thousands of individuals. The authors found that the escaped plants could hybridize with each other to create novel combinations of transgenic traits, and the authors argue that their result more than 10 years after the initial release of genetically engineered canola raises questions of whether adequate oversight and monitoring protocols are in place in the u s to track the environmental impact of biotech products. Berkeley's [00:26:30] own cell Perlmutter is sharing the Nobel Prize in physics with Adam G. Reese of the John Hopkins University and Brian Schmidt of Australian national universities, Mt. Strom Lowe and siding spring observatories pro mudder led the Supernova
Speaker 7: cosmology project that in 1998 became one of the two scientific efforts that are credited with discovering the accelerating expansion of the universe and Schmidt led the competing supernova search team. Pearl mudder is UC Berkeley's 22nd Nobel Medal [00:27:00] winner and the ninth winner of the Physics Prize. The discovery of the accelerating expansion has formed theories of the distant future of an ever expanding universe and has alleged the speculation of dark energy that theoretically makes up almost three quarters of the matter and energy of the universe, but it has proven elusive to observe. Perlmutter has recently been working with NASA and the u s department of Energy to build and launch the first space-based observatory designed specifically to understand the nature of dark energy.
