The Internal Combustion Engine.
Some facts about the engine we use for most of our transportation :
- efficiency : around 15-25 % in ideal, real world conditions (38% in a frictionless world aka thermodynamics)
This means : you put in 100 dollars worth of energy and get 20 dollars out of it in movement,
so 80 dollars are wasted (heat, polution, friction, noise)
Crazy if you ask me.
- The enviroment : direct impact : toxic fumes, greenhouse gases, (oil) leaks, noise,...
indirect impact : production of fossil fuels has shown to be dangerous for the enviroment (oil spills, reffinery accidents or even day to day operation)
- needs a gearbox to deliver usable power.
- Maintenance : needs a lot, cost of ownership is high
- The good thing : high range, because of the high energy density of fossil fuels
The Tesla Roadster: 100% electric car, 3,9 sec to 100 km/h
390 km radius on a full battery. Not bad !
My favorite car design : The Dodge Charger R/T '69.
A real gas-guzzler. I'm waiting for the electric (con)version ;-)
Some facts about the engine a wise consumer would choose: if he was given the fair choice :
- efficiency : around 80 %, actualy more in most cases.
This means : put in 100 dollars worth of energy and get 80 dollars out of it in
movement, so only 20 dollars are wasted (heat, friction, noise)
Acceptable if you ask me.
- The enviroment : direct impact : you can smoke your tires faster ;-)
indirect impact : production of electricity can be dangerous for the enviroment if we don't use renewable sources (geothermal energy, windmills, solar plants,...)
Worn out batteries do not belong on the garbage belt, they need proper recycling !
- doesn't need a gearbox to deliver usable power, high torque from zero to xxxxxxx rpm.
- Maintenance : practicly none, cost of ownership is low
- The bad thing : lower range, because of less energy density of batteries compared to fossil fuels. But a lot of progress has allready been made !
- Batteries today are more expensive than a fuel tank, but this guy has found a good solution if you ask me : "batteries not included" : Shai Agassi's bold plan for electric cars or take a look at betterplace.com
Now as we should all know the real problem lies in the fact that we are living in a profit driven "society". This eventually means that the producer is forced to choose the technology that makes the most profit and not the one that is the best, the most efficient one.
If you want to know more about this watch : Zeitgeist,
"Think for yourself, don't blindly swallow the information you receive and do not annalyze all information based upon what you (think you) already know."
It is your right to have your opinion as is everyone else, but that doesn't make your opinion the right one nor it makes mine or anyones opinion correct, we can all learn if really we listen to eachother. And last but not least : "The solution that produces the most money/power in the short and/or long-run isn't necessarily the best. In history money was a solution, shortly after it became the one of the main causes of problems in human society."
