Of course we can replace fossil fuels but only if we rid ourselves of mythology such as pretending the high cost intermittent renewables - solar and wind - can do it all.
The cheapest and most powerful energy source on earth is Mother Earth herself, far more powerful that all others combined, but the poor lady gets no respect. Ignorance of that simple fact of life could be the death of us all. Knowledge could set us free.
Waste heat engines have been around for a very long time and come in a variety of modes.
Though most are cylindrical today, the earliest ones were piston driven.
No law of thermodynamics is violated.
"With the Captors of sun and wind, and their applications ( CSW A ), everybody can achieve 100% renewable energy and energetic independence"
Sorry, Marian. Comparing the lightweight, sometime energy to baseload renewables is like comparing butterflies to an oak tree.
An architect boasted about using solar for his home, which was also his workplace. He used the solar to power his light tables used in his work.
I asked him if he dressed in very warm clothes and blankets and used a seeing-eye dog for getting around at night.
He took it in good humor.
In reality solar and wind power is very expensive while geothermal power is the cheapest on earth. Waste biomass cleans up things - for those worried about the environment.
>“I don’t know why we have not utilized geothermal energy much more, for example, in Japan,” the minister said.<
That's strange. I know why the safe nuclear power was little developed in Japan while the dangerous nuclear power was being developed with gusto. But how would Japanese, of all people, know about the destructive potential of manmade nuclear power ? :-)
You see, utilizing the extremely hot geothermal brines for power instead of letting them cool off a bit for the Japanese baths in the northern islands could remove the spirits from the waters much like Hawaiians fought the use of geothermal power for fear of offending Pele, the Goddess of Power.
Japan completes ferociously with China to sell equipment for geothermal power plants just as Canada is a hefty incubator of geothermal power startups but has not one geothermal power plant of its own.
Oscar Levant defined marriage as the triumph of habit over hate. Habit, superstition and monopoly are hard to overcome. Hate is another subject.
"For example, the country is well placed for the use of solar energy. Azerbaijan located in the hot climate conditions and has from 250 to 280 sunny days per year with a very high level of lightning,"
Even with all that sun - and wind - there will be nights when the sun don't shine and times the wind don't blow and what will Azerbaijanis do without a bolt box where lightning bolts can be stored?
The universal appeal of intermittent energy is the foolish path that will not lead to freedom from fossil fuels.
Baseload renewables like geothermal, biomass and even the troublesome hydropower are the way to salvation.
"Azarbayjan has many potentials and surely is moving in the right direction."
I have no quarrel at all with using intermittent energy in splendid niches and for supplementary power when needed and available.
But to focus on sometime power instead of baseload renewables assures the continuation of fossil fuel addiction and continuation of destruction of the planet.
In this life, one must make choices. Money, more than energy, has limitations.
How's come countries like Tanzania can afford the cheapest and most potent power on earth - Mother Earth herself - and the U.S. has to diddle with unreliable, expensive feebles like solar?
"[The Chinese] told the inventor they didnt care about patents"
Geez, Jim, that is scary. Sounds like American companies. See Google vs. Vringo for an example in the headlines.
Who says biofuels must be liquids or gases?
Ever hear of dust burners?
One private company is attempting to commercialize "dust" [uniform microsized particles] "as natural gas."
Certainly liquid fuels have an advantage, especially with drop-in fuels, in requiring little or no modification of current engines.
Dust particularly has a problem with density while newer briquettes can be quite dense.
Fascinating work here that could lead to a clear winner but there is a too narrow focus IMHO.
"Germany has explored ways to address energy issues at the very root of the matter, ie demand"
Good Lord, you mean to say Germans are actually addressing needs rather than mythological equivalence of baseload and intermittent renewable energy sources?
Whatever is this world coming to?
Equitable pricing is difficult enough but elementary in comparison to dealing with the politics of concentrating on the worst of the renewables - the unreliable wind and solar.
Geothermal, the most reliable, most potent and cheapest of all energy sources isn't mentioned but Germany has pioneered in the field.
One could begin to get the idea German engineers really are as good as rumors say they are. :-)
"we tend to create a negative value system about fossil fuel without fully assessing its merits"
How many have recognized that extermination of human life will almost surely hasten the evolution of an intelligent species? Is there any higher cause than self-sacrifice of one's entire species for the benefit of Mother Earth and the universe?
Possible a collision with one of those large rocks or dirty snowballs will do us in first but I would be more inclined to bet on global warming like most scientists.
Thank you for the perspective.
