  1. Look at the massive fresh water aquifers under Libya. Gaddafi wanted to pump this water up, using solar panels and wind turbines, greening the desert. Once the land is darker with greenery the rain will come. Many say this proposed project was a prime reason why he was taken out - he would be powerful.

  2. In a tank of liquid fuel only around 20% is used to propel the vehicle. The rest is wasted. That is not that case with a battery/electric motor setup. Toyota say they will be selling solid state batteries in five years. These have around three times the energy density as current batteries. Righting off electric planes is foolish. An electric hybrid is clearly feasible.

  3. You need to understand the qualities of graphene.

  7. Germany has a hydrogen fuel cell train on fare paying operation. The UK is to trial them soon. The UK is looking to use hydrogen in trains to preclude overhead wiring of track which is expensive to install and maintain. The electrification programme has been put on hold. New trains will be diesel/electric hybrids that can be easily converted to hydrogen fuel cell, using the existing electric traction motors, when needed. Hydrogen makes sense when the electricity to crack the water to obtain the hydrogen is cleanly and freely obtained, like wind, wave, etc.

  8. Dyson turned a vacuum cleaner into a design product. Nothing looked like it, it stood out, a must have product. I had one and they are good.

  9. The Qattara Depression in Egypt is below sea level. It is a vast area with only about 200 people in it. There have been suggestions to dig a canal to the Mediterranean filling it up creating a large lake with seep sea vessel access. Ports could emerge on its banks. They could create the ports before it fills up making construction easier. It will take many years to fill, so a number of canals may need to be dug. This vast water area will change the climate for sure, with most saying it will increase rain, making the deserts greener. The only problem is that it will be salt water. So, others have suggested diverting the Nile into it. Factoid: In WW2 at El Alemein, the British army had the Qatarra Depression on its left flank and the Med on its right. In front of them was the German army. They had to go right through them head on - through half a million mines as well.

  10. The inefficient internal combustion piston engine will save the world? What parallel universe are they in?

  11. I gleened that the reduced water levels are due mainly to evaporation. Well this water that ends up in the air drops somewhere as rain, which is then beneficial. Where does it mainly drop as rain?

  12. A company proposed to convert the natural gas network in the city of Leeds in England. A simple to job to convert natural gas appliances to Hydrogen.

  13. HIgs-speed rail can replace many air flights. Trains tend to go right into city centres, giving faster door to door journey times.

  14. It is said the Liverpool School of Tropical Medicine built the Panama Canal. They linked the mosquito with malaria and other diseases. They also developed the quinine to counter the diseases.
