DME is a great fuel for many reasons. There is not enough biomass,of any type however, to fuel a large percentage of the trucks of the world. This was proven when England was burning wood and nearly deforested the whole country so that laws had to be passed to preserve enough wood for shipbuilding. Iceland, also, once had forests and wound up with few trees. Cars and trucks can be built to collect the CO2 that they produce and drop it off at filling stations like so much used oil. These vehicles can be made cheaper than fuel cell vehicles. Electricity from nuclear powerplants can be used to make DME from the CO2. But before that Norwegian gas can be used to make DME and even COAL.

It is now time to start considering what methods we will use to electrify the freeways. First the commuter lanes of California should have conductors put in the pavement. Many politicians are trying to cut CO2 emissions without realizing that the higher costs of energy will kill people who will freeze and starve and won't visit doctors even for curable diseases.

Solar and Wind electricity costs two to ten times more than Coal and Nuclear because of capital costs. There is enough Uranium in the ocean to fuel all of civilization for thousands, if not, thousands of thousands of years. There is enough uranium, sitting in used fuel storage at nuclear power plants, to fuel US power for a hundred years. CANDU reactors could burn some of it tomorrow without any further research or chemical reprocessing. Just form it into the right shape and put it into the reactor. Some of it now could be put right back into the reactor that it was taken from for a few more kilowatt hours.

Did your ancestor worry about you when he ate the last dodo bird or stellar sea cow or passenger pidgeon. Solar energy can be economically used for heating water and even houses, but solar cells are getting most of the attention.

The biomass of the oceans is now being depleted by massive fishing for animal feed while corn is being burnt. I would like to thank all of the people and commpanies that are doing work on energy issues.. ..HG..

It will be iteresting to see how DME shapes up as far as energy conversion efficiencies and the lubricicity/ polymer incompatability as experience is gained in new methods of production.
It may be an answer to the increasing divergence from both the traditional ic engine manufacturing plants and increasingly divergent fuel formats as a host of new fuels try to find a place in the market.
As many proposed (and current fuels are synthesised to some degree and the prospect is for increasing reliance on these techniques to allow a greater quality control in the tighter emission future , D.M.E. needs to be better understood .
