Its a disgrace the way we dont act.
We are slaves to energy.
if everyone would just do something everyday to lower their
personal energy consumption , the resulting decrease in the demand for energy would lower all food and energy prices and remove the need for Bio fuels.
a single step by each person multiplied by all people is what we need.
it will be the people of the world that will decide their fate
not those who decide what types of energy we use.
a car that uses a 90% efficient gas turbine engine
that turns a generator
that charges a battery
that powers a electric motor
could run with a 3.5 H.P. gas turbine engine.
the turbine could stay at a constant speed and charge the battery when you are stopped or at low speeds when you are traveling on the freeway at higher speeds the generator could be clutched off and the cars momentum can be maintained through direct drive using a reduction gear.
it doesnt take much to maintain momentum ever notice how far down your gas pedal is pressed when traveling at 55 mph?
a piston engine is only 10% efficient.
10 H.P X 90% efficent gas turbine = 9 H.P.
90 H.P X 10% efficient piston engine = 9 H.P.
Oh your probably wondering why I first said a 3.5 H.P. gas turbine engine... well gas turbines usualy turn at a very high rpm lets say the turbine turns at 10,800 rpm ( its a slow one )
10,800 rpm ... is way to fast for a electric generator
you would have to use reduction gears to decrease the rpm to a stable generator rpm of around 3600 this means that the 3.5 H.P. gas turbine is delivering apx 3 X the input H.P. which makes the output H.P. apx 10.5 H.P.
a lawn mower engine sized gas turbine can provide plenty of engine to power a good sized gas turbine electric car.
but it will be the people of the world that will demand a change
in energy that will accomplish such as this , not those who make more when you buy more , and not the governments of the world either , it will be the people.
