Remundo,
Solar CSP faces significant challenges:
- thermal storage for nighttime electricity production: no CSP plant in the world currently produces 24H / 24 in the 100% solar mode. The Spanish power stations PS10, PS20, ANDASOL etc. are hybridized gas.
- significant water consumption (condenser, purge circuit, cleaning mirrors) in areas where water is scarce.
- production varies significantly between winter and summer
etc.

well or drilling
The great advantage is having a briny borehole rich in minerals, and the cost is different; a lot, it only remains to sterilize the water to sow algae!
In any case, discoveries will also go into the diet, we will realize that we can feed ourselves (identical to the first pressures, oils of better quality); We will make a seaweed vinaigrette! In addition to olive oil, rapeseed and sunflower we could have oil Chaéto, Isoc or other.

okay solar photovoltaic gives the highest power by m2, but we must also pay them at high prices
Inversely biomass, especially firewood, gives less energy per m2 but is built alone without paying anything: we cut the wood when we want
the algae give theoretically a little more energy by m2 but it is necessary to pay the basins: it is not an inerressante solution in the general case, but very interesting to exploit a water enriched in co2
alas I do not know enough yet to test ...

Here is an application of microalgae that seems to me quite reasonable;)
At the protein level (protein content, essential amino acids, etc.), Spirulina breaks all records:

For people who suffer from undernutrition or malnutrition, it is an ideal food.

Reasoning from a European consumer point of view:
1 Photovoltaic kWh = $ 40 cents
VE 20 kWh / 100km = $ 8 cents / km
+ $ 3 cents / km (battery)
= $11 cents / km
Thermal car:
- $14 cents per km in Europe with petroleum fuels
(bio-agrocarbs cost even more)
With the microalgal fuel car, it costs $140 cents per km (!)
Conclusion:
Driving in Europe with an electric car with PV electricity is cheaper than driving with a thermal car burning agri-biofuel.
The obstacle lies in the level of investment:
if it were imposed for the motorist who buys a gasoline car to buy at the same time the fuel that he will consume on 10 ans + to pay his share in the infrastructure (offshore platform, tanker, tanker trucks, service stations, etc.) that provided fuel, no one would buy a thermal car. the economic model of the petrol car is viable today because it allows the motorist to buy his fuel little by little, and because he is also allowed to repay (without being really aware of it). elsewhere) the investment of the infrastructure (offshore platform, gas station etc.) little by little. But ultimately, the oil car budget is a sinkhole.
To overcome the obstacles to the development of the electric car powered by green electricity, it is necessary to innovate on the business model, and innovative solutions are now available (state-of-the-art states are currently switching to a truly thunder). The problem is not technical.
