They do not say, "I want better hot water in the showers.

One seemingly small aspect of the overall relief effort became increasingly important as the delivery of food and water started rolling.

January and February are the dry months in Haiti, yet many of the camps had developed standing water.

So a river is designed to channel the flow of water, and the lightning bolt that comes out of a cloud channels the flow of electricity, and a leaf is designed to channel the flow of nutrients to the tree, sometimes even having to route around an obstacle, but to get that nutrition flowing.

I thought I would start with a very brief history of cities. Settlements typically began with people clustered around a well, and the size of that settlement was roughly the distance you could walk with a pot of water on your head.

You had water, sewer networks that allowed for this kind of unchecked expansion.

Some years ago, I set out to try to understand if there was a possibility to develop biofuels on a scale that would actually compete with fossil fuels but not compete with agriculture for water, fertilizer or land.

The algae that grow are in a container that distributes the heat to the surrounding water, and you can harvest them and make biofuels and cosmetics and fertilizer and animal feed, and of course you'd have to make a large area of this, so you'd have to worry about other stakeholders like fishermen and ships and such things, but hey, we're talking about biofuels, and we know the importance of potentially getting an alternative liquid fuel.

Well, the reason we're doing this offshore is because if you look at our coastal cities, there isn't a choice, because we're going to use waste water, as I suggested, and if you look at where most of the waste water treatment plants are, they're embedded in the cities.

This is the city of San Francisco, which has 900 miles of sewer pipes under the city already, and it releases its waste water offshore.

So different cities around the world treat their waste water differently.

Some cities just release the water.

But in all cases, the water that's released is perfectly adequate for growing microalgae.

We put waste water and some source of CO2 into our floating structure, and the waste water provides nutrients for the algae to grow, and they sequester CO2 that would otherwise go off into the atmosphere as a greenhouse gas.

They of course use solar energy to grow, and the wave energy on the surface provides energy for mixing the algae, and the temperature is controlled by the surrounding water temperature.

The waste water that leaks out is water that already now goes into that coastal environment, and the algae that leak out are biodegradable, and because they're living in waste water, they're fresh water algae, which means they can't live in salt water, so they die.

So we may be able to go beyond that when thinking about this system that I'm showing you, and that is to say we need to think in terms of the water, the fresh water, which is also going to be an issue in the future, and we're working on methods now for recovering the waste water.

We also set up experiments in San Francisco at one of the three waste water treatment plants, again a facility to test ideas.

Now, we grew algae in waste water, and we built tools that allowed us to get into the lives of algae so that we could monitor the way they grow, what makes them happy, how do we make sure that we're going to have a culture that will survive and thrive.

We basically take waste water with algae of our choice in it, and we circulate it through this floating structure, this tubular, flexible plastic structure, and it circulates through this thing, and there's sunlight of course, it's at the surface, and the algae grow on the nutrients.

So the next thing we had to figure out was how we could remove the oxygen, which we did by building this column which circulated some of the water, and put back CO2, which we did by bubbling the system before we recirculated the water.

Well, we found of course that this material became overgrown with algae, and we needed then to develop a cleaning procedure, and we also looked at how seabirds and marine mammals interacted, and in fact you see here a sea otter that found this incredibly interesting, and would periodically work its way across this little floating water bed, and we wanted to hire this guy or train him to be able to clean the surface of these things, but that's for the future.

But we don't have a lot of time, and I'd like to show you the artist's conception of how this system might look if we find ourselves in a protected bay somewhere in the world, and we have in the background in this image, the waste water treatment plant and a source of flue gas for the CO2, but when you do the economics of this system, you find that in fact it will be difficult to make it work.

Unless you look at the system as a way to treat waste water, sequester carbon, and potentially for photovoltaic panels or wave energy or even wind energy, and if you start thinking in terms of integrating all of these different activities, you could also include in such a facility aquaculture.

San Francisco produces 65 million gallons a day of waste water.

If education can be likened to watering a garden, which is a fair metaphor, sadly, much of the water is evaporating before it reaches the flowers, especially for some groups, for example, those with hearing impairment.

But what we have to recognize now is that we are reaching the ecological limits that our planet can bear, and when we chop down forests, as we are every day, to grow more and more food, when we extract water from depleting water reserves, when we emit fossil fuel emissions in the quest to grow more and more food, and then we throw away so much of it, we have to think about what we can start saving.

It's a living organism, cut the slice off, stuck it in a vase of water, it was all right for another two weeks after this.

You can make a biocensor out of yeast to detect pollutants in water.

It essentially raises charitable funds from individuals, foundations and corporations, and then we turn around and we invest equity and loans in both for-profit and nonprofit entities that deliver affordable health, housing, energy, clean water to low income people in South Asia and Africa, so that they can make their own choices.
