Nano-Storage, the Store-Gen Grid and Hurricane Ike

Hurricane Ike has given us a massive object lesson on the importance of implementing the late Rick Smalley’s vision of the Store-Gen Grid (SGG; graphic courtesy Wade Adams at Rice’s Smalley Institute) – a highly distributed network of granular electric production and storage.  One of the elements of the SGG concept is a household storage unit for about 100 kW-hrs of dispatch energy. 

 Smalley's Store-Gen Grid Concept Could Keep The Lights on After a Hurricane

Well, we ain’t there yet.  Of all the standard infrastructure services, only two seem to be reliable in a pinch: cell phones and natural gas.  The electric grid is plainly extremely fragile.  This is a major opportunity for nanotechnology.  With a major power outage in the energy capital of the world, this topic ought to get *lot* more traction, and fast.  So get your thinking caps on.  According to the Houston Chronicle, nearly 3 million people lost power due to the storm.  So I reckon there are about 3 million ready customers for the next big thing in distributed power.  I’m one of them!

 

Now, when considering storage technologies, energy density *really* matters!  Among practical materials, nothing is even comes close to gasoline or diesel fuel.  Just before the storm, my wife was wise enough to ignore my objections and bought a neat little Honda 2kW generator.  I got ten gallons of gas on Friday, and used about five gallons over a 36 hour period.  This was just enough to keep the refrigerator going, charge cell phones, and run a lamp, two fans and a small TV set.  This enabled us to essentially camp-out in our house.  Forget about air conditioning, running the washer/dryer or taking a hot shower (the darned water heater has an electric starter).

 

Here are some representative (volumetric) storage energy densities (from Wikipedia):

 

Technology or Material

Energy Density ( MJ / liter )

Capacitor Ultracapacitor

~ 0.050

Lead acid battery             

~ 0.15

Flywheel

~ 0.50

Lithium ion battery     

~ 1.50

Hydrogen Fuel Cell 

~ 1.62

Li Ion w/ nanowires   

~ 2.60

Ethanol                 

~ 24.0

Gasoline                

~ 34.6

 

Let’s look at the Lead-Acid Battery (LAB) as an example, since it’s still the workhorse for storing electric energy.  My five gallons of gas would equate to 4,383 liters of lead-acid batteries (LABs) (3.8*5*34.6/0.15).  My total investment for generation and storage was $1020 ($1000 generator, $20 gas).  How much does 4.3 cubic meters of LABs cost again? - about $20-$50/liter?  And how much does it weigh?  I can (and did) carry (lug) the generator and the five gallons of gas myself at the same time. 

 

Overall, electrical storage energy density is worse than chemical storage a good factor of ten or more.  An order of magnitude (or two) is nothing to sneeze at!  It is plain that without sufficient oil/gasoline/diesel, we are in a world of hurt for the foreseeable future.

 

Each of the technologies listed above employs, or can be improved with, nanotechnology or nanostructured materials.  Let’s do a little math and get a handle on the nano-scale challenge involved here.  If gasoline has an energy density of, say, 35 MJ/l, it equivalently contains about 3.5 x 10-17 Joules per cubic nanometer.  Modeling this as a parallel plate capacitor in vacuum with a 1 nm gap, you get the target energy density with a voltage difference of about 2.8 Volts.  If you use a decent dielectric like TiO2 (k = 40ε0) instead of vacuum, you only need 0.44 V.  About 1 V/nm is a pretty stiff electric field, but not larger than those considered routine for ultra-thin gates in the semiconductor industry.  This all seems pretty doable; making the nanowire connections to the outside world will be the tricky part; it’s probably a job for carbon nanotubes or maybe graphene.  Rick would have liked that. 

 

I hope somebody out there gets to work on this pronto!  Even at $100 / liter, it would be a useful technology.  When you get the cost down to about $10 / liter, you’ll be a bona fide hero, and a very wealthy one at that.

The Technology Center of West Houston & Katy Dock to Open Doors September 17th


Houston continues to demonstrate its focus on early stage technology startups with the launch of two additional supporting cast members: The Technology Center of West Houston and The Katy Dock.

The Technology Center of West Houston (TCWH), a Katy Area Business Incubator and Accelerator, has created an exciting new opportunity for early-stage technology companies in the Katy/West Houston area. The mission of the TCWH is to enable, launch and accelerate technology companies in Katy/West Houston and thereby create jobs and economic growth.

TCWH matches entrepreneurs and inventors with seasoned business professionals experienced in commercialization in several fields, including engineering, internet technology, hardware and software development, energy, medical related technology. Assistance is offered in strategy development, planning, capital funding, and professional areas. The TCWH is a joint initiative of the Katy Area Economic Development Council, HCC-Katy, Houston Technology Center, Smalley Institute at Rice University, JBMA, Inc., and the IP law firm of Patterson and Sheridan.

Along with the TCWH, West Houston will also be getting its first coworking facility with the Katy Dock. The Katy Dock allows Katy/West Houston area entrepreneurs, inventors, consultants, developers, and designers to work in a creative business atmosphere and successfully grow a company. The new Katy Dock facilities are available through the Katy Commerce Center. Professional advice, business mentoring and other consulting services are available through the onsite TCWH office. Pricing for Katy Dock starts at ‘free’ for once-a-week drop-ins to pricing levels for private desk space and dedicated offices. Warehouse, fulfillment and light manufacturing space is also available onsite, all at a fraction of the cost of traditional office leasing arrangements.

REBarCamp coming to Houston

Real Estate BarCamp Houston, TX

Real Estate BarCamp Houston, TX

If you know me well, you’ll know that I have a passion for collaboration and events like BarCamp. Mike Price of MLBroadcast.com has coordinated Real Estate BarCamp in Houston next month on October 22, 2008.

Taking directly from the site, REBarCamp is:

REBarCamp Houston is a gathering of minds and open format event where real estate and technology professionals can learn and share discoveries and trends happening in the business, and discuss the future of the industry.

BarCamp is open to anyone. And anyone who wants to can attend and host sessions.

I am a huge advocate of these specialized events. That is why I have been working with various groups around town to have a BioCamp and GreenCamp in Houston this year. Do you have an idea for a Barcamp-esqe event? Let me know if I can help.

Ripening Houston

Yesterday, Josh Tabin gathered the Startup Houston contributors to lunch at El Meson; the company and the food were both spicy and excellent (thanks, Josh!). Collectively, and individually, our goal is to help transform Houston into a dynamo of entrepreneurship.

Of course, the main discussion was about start-ups and the environment where they originate and grow – and what we could do to help. As in any conversation about start-ups here, the disappointing fact came up regarding how venture capital is so concentrated on the East and West Coasts (the Bay Area and Boston) and how Houston (and indeed Texas and the other 48 states) is ignorable fly-over country.

I’ve heard comments like that for a long time. And while is certainly true that the preponderance of venture capital and start-ups are both concentrated in those areas, stopping the conversation there, as often happens, isn’t constructive. It makes me think of frustrated bird-watchers looking for some rare scavenger species with a weird diet (e.g. start-ups that can’t live without vitamin VC).

The musing geek part of me is also reminded of Ostwald Ripening (Figure from Wikipedia). This describes process by which a large ensemble of small particles usually ends up as a small collection of large particles. It’s often an important issue in nanotechnology. You can see a very nice simulation of the process here (warning: big animated gif).

Here’s the point: is there some social or business process that makes start-ups diffuse to where the VC’s are? Maybe so – I need to ponder that some more. I’m pretty sure that it accounts for the old adage about the rich getting richer. Perhaps it also explains why there is more money in banks than laying on sidewalks, and why trash ends up in landfills (OK, maybe not on those two).

But back to the lunch discussion - of course, we got past the forlorn birdwatcher stage quickly. We all have particular perspectives about important growth factors.

Here’s mine: I think that start-ups come from combining customers with ideas in the presence of an entrepreneur. Now that can be an explosive mixture – fuel, oxidizer and spark. But I’m talking about real customers – live people you meet face to face that have real problems they’ll pay money to resolve. And real ideas – potential solutions that arise from some well informed knowledge about how things work – and how you might be able to make them work better. Of course, you can have a business idea essentially in a vacuum, but if you’re idea serves some faceless ‘market’, you’d better track down a real customer to vet it. And if you have a general idea for a better widget, you’d better find some technical specialist to validate the approach (or learn enough to do it yourself).

The rate limiting step is thus connecting customers with potential solutions. (I know it’s true for me – every time learn about the key problems in an industry, I come away with a year’s worth of ideas). Note that no money of consequence is needed for this. So far, VC’s are irrelevant. I reckon that a big reason Silicon Valley shines for start-ups is because there are a lot of ideas and a lot of customers in a small area. The staff churn out there (yuck!) probably accelerates the process, too. Note that most of the start-ups there involve electronics or software. In my experience, the initial barriers to entry in those fields are generally low and the costs to make or mock up a demo are pretty low, too.

I think that Houston has plenty of customers, and I know that there are lots of well-informed technologists here. So what’s missing? Two things come to mind – Houston is very spread out compared to Boston and the Bay Area, and our major industries, energy and health care, are capital-intensive monoliths. So the flux of entrepreneurial connections is lower, and the barriers to entering the market are fairly high.

The flux issue can be partially addressed by mixer conferences – like the Rice Alliance, BioHouston, Houston Technology Center and Startup Houston events. These are great; we need to grow them and multiply them. And generate some new meetings that are more technology/industry specific. The cost of seeding an idea is a problem if you’re going into energy or biotech, though. My general suggestion is to bootstrap aggressively by using SBIRs and STTRs and connecting with academic laboratories at Rice and the University of Houston. This approach allows you to get to the demo stage while you keep your day job. I’ll write more about that later.

I’d finally observe the obvious – energy is THE hot topic nowadays, and Houston is the world’s energy capital. So we have a big natural advantage and we really should exploit it. I’d note also, that there is an important new trend towards distributed energy - this means small granules of generation and storage at the point of consumption. Thus, some of the monolithic nature of the energy industry is getting deconstructed. This is a MAJOR opportunity for Houston entrepreneurs.

I hope to have a lot more to write about distributed energy in the near future – if you have stories, applications, events, etc. on this, please let me know.

Is a Ph.D. Required to be a Biotech Entrepreneur?

Graham Randall is a regular contributor to Startup Houston on the topics of biotech, life sciences and entrepreneurship.

Do you need a Ph.D. to be a Biotech Entrepreneur? This seems to be a popular question these days, even though I think the answer is pretty obvious: No.

There are lots of biotech entrepreneurs out there without Ph.Ds. What really matters is what role you want to play in your startup company. If you want to found a company and be its lead scientist, then obviously a Ph.D. will be required. Not just for the credential, but because it’ll take you several years to acquire the knowledge necessary to do the kind of research that yields results with commercial potential.

But if your intent is to be the founder and general manager of a biotech company, then the value of a Ph.D. is diminished.

Why would you need a Ph.D.?

The knowledge you gain from earning a Ph.D. will help you evaluate technologies. Even when you’re evaluating technologies that aren’t directly in your field of expertise, the critical and analytical skills you learn in acquiring a Ph.D. will help you quickly get up to speed and start asking the right questions.

You’ll also learn some leadership skills while doing your Ph.D. You’ll gain experience giving lectures and communicating your ideas. You’ll learn how to think on your feet and handle tough questions. And from these experiences, you’ll gain some confidence.

The Ph.D. is also a credential that will allow you to apply for grants on your own. Even so, if you’re not the inventor of your technology, then your partner, the inventor, will probably have a Ph.D.

Why don’t you need a Ph.D.?

If your goal isn’t to be the Chief Scientist of a biotech company, then the 4-7 years you spend in a lab trying to get a Ph.D. would be better spent working at a biotech company gaining practical business experience. Working in a company will not only teach you a lot of technical business skills like finance and accounting, you’ll also be exposed to a variety of management styles, team work, project management, quality assurance, manufacturing, regulatory approval, and sales and marketing. This is the experience you’re probably not going to get in the lab, but it’s crucial to starting a company.

Conclusion

No, I don’t think a Ph.D. is required. Getting a Ph.D. is a personal decision. If you feel passionately about science, or if you have a strong personal compulsion to “phinish”, then go get your Ph.D. But if you think it’s only a means to an end, I think your time is better spent getting real world experience. Maybe even get an MBA (which will be the subject of a future post).
