The big problem with solar energy is the area needed to harvest significant amounts of power.

Second that.
Fuels all have a nasty side effect, from CO2 emission to possible food shortage.

My Brother in Law is running a Nissan Serena on waste from the local chippy just filtered with a seive. The problem with the waste oil is animal fats that are solid at low temperatures but in the current weather its fine. When his filter gets blocked he boils it in water and the animal fats float to the surface. Not sure if I fancy this in the tranny though and I'm sticking to nice clean new oil.

The big, and I mean BIG difference between the carbon we're spewing into the atmosphere by burning fossil fuels and the carbon we spew into the environment using "alternative" fuels like the algae and bio diesel, is the source of that carbon.
FF carbon has been locked away in the earth's crust for millions of years, and if we want to keep the climate we all know and love, then it's better for all concerned if we leave that previously sequestered carbon just where it is and not introduce it into the ecosystem.
The carbon ( or CO2 ) actually, "generated" by burning alternative fuels is carbon that's recently been in the ecosystem so technically, it doesn't contribute to our current situation re global warming.
What do plants use as a carbon source to create their constituent molecules ?

I'm unsure of what sort of scale we'd have to enter into if we want to make a significant impact on the amount of fossil fuels we use. Might we have to sacrifice the whole Sonora desert to meet out energy needs?

There is a slight possibility that I am not actually right all of the time.

Food prices hit record levels this year. A third of the increase, estimates the International Food Policy Research Institute in Washington, DC, is due to increasing demand in the US for maize to make ethanol for fuel.
The IFPRI says this should stop. There should be a moratorium on using food for fuel, it says, as world food production is already barely enough to feed us all. There are just not enough crops to make our fuel as well.

Currently most research into efficient algal-oil production is being done in the private sector, but if predictions from small scale production experiments bear out then using algae to produce biodiesel, bioethanol and biobutanol may be the only viable method by which to produce enough automotive fuel to displace current world gasoline usage.[17]
Microalgae have much faster growth-rates than terrestrial crops. The oil yield per unit area of algae is estimated to be 5,000 to 20,000 gallons per acre, per year (4.6 to 18.4 l/m2 per year); this is 7 to 30 times greater than the next best crop, Chinese tallow (699 gallons).[18]
The difficulties in efficient biodiesel production from algae lie in finding an algal strain with a high lipid content and fast growth rate that isn't too difficult to harvest, and a cost-effective cultivation system (ie, type of photobioreactor) that is best suited to that strain. Additionally, a cost-effective way to extract the oil must be found.
Open-pond methods have largely been abandoned for the cultivation of algae with high-oil content. Many believe that a major flaw of the Aquatic Species Program was the decision to focus their efforts exclusively on open-ponds. Algae in an open-pond environment are subject to wide swings in temperature and pH, and competition from invasive algae and bacteria. Open systems using a monoculture are also vulnerable to viral infection. The open-pond method makes the entire effort dependent upon the hardiness of the strain chosen, requiring it to be unnecessarily resilient (compared to a closed system) in order to withstand the environmental conditions. For a given amount of photosynthetic energy, an algae strain producing relatively high levels of oil will produce relatively less protein and/or carbohydrate, usually resulting in the species being less hardy, or having a slower growth rate. Algal species with a lower oil content, not having to divert their energies away from growth, have an easier time in the harsher conditions of an open system.
Some open sewage ponds trial production has been done in Marlborough, New Zealand.[19]
A feasibility study using marine microalgae in a photobioreactor is being done by The International Research Consortium on Continental Margins at the International University Bremen.[20]
Research into algae for the mass-production of oil is mainly focused on microalgae; organisms capable of photosynthesis that are less than 2 mm in diameter, including the diatoms and cyanobacteria; as opposed to macroalgae, e.g. seaweed. This preference towards microalgae is due largely to its less complex structure, fast growth rate, and high oil content (for some species). Some commercial interests into large scale algal-cultivation systems are looking to tie in to existing infrastructures, such as coal power plants or sewage treatment facilities. This approach not only provides the raw materials for the system, such as CO2 and nutrients; but it changes those wastes into resources.
The corporations Chevron, Honeywell, and Boeing are starting algae businesses. According to Boeing's technology leader for energy and emissions, Dave Daggett, 'In the past two years, we have changed from algae skeptics to proponents'. [21] The development challenge is to reduce the cost of producing algae oil in commercial volumes, i.e. billions of gallons.
"'In Europe, refiners are producing 1.4 billion gallons a year from rapeseed, soy, and other plants. In all, the world consumed $1.7 billion worth of biodiesel last year. That should grow to $26 billion by 2020, says market researcher Global Insight.'" [21] These figures project an average growth of over 20% per year.

Deserts - as in "non arable land" might play a more significant role in the planets eco system as we currently predict. Yet: deserts are expanding annually and the 'newly acquired land' could be used to generate this kind of fuel without much interference.
