Climate Change, 'Greenhouse' effects, Environment, etc part III

Ridiculous.

Charging and discharging batteries is at best only 70% efficient in both directions.

That's better than the internal combustion engine's theoretical maximum of 50%, and batteries are much, much better in practice than the internal combustion engine's actual efficiency. :^D

Are you proposing to run the world on AA batteries? Or have you forgotten it takes an engine to charge a battery?

FALSE:

There isn't a battery operated car out there that get over 100 miles a charge.

Model S has three battery options.
The largest battery supplies 300 MILES OF RANGE at 55 MPH.

Cost is the only factor.

It takes electricity to charge a battery, not necessarily an engine. Wow.

To be fair most electricity is generated by some kind of fossil fuel engine.

Might I suggest going to your local utility website and trying to find the same information.

Bio waste is "renewable". It is basically sewage or garbage, from renewable sources and carbon neutral.

This is not FOSSIL fuel.

I would presume Unspecified is from out of state sources and they do not have specific numbers on it. So electricity from Oregon/Washington would be primarily hydro/nuclear, and from nevada most likely nuclear/solar/hydro.

But certainly saying it is primarily fossil is FALSE.

You two beating each other up isnt solving anything. How about some ideas instaed of bashing each others belife about global warming.

Do you both think that we need to get off fossil fuels in the long run?

Here are my ideas. Where there is an abundance of water use hydro electric. There is a tide twice a day. start using that tide to generate power, It seems the Thames river would be ideal for that. You have those storm gates, Why not upstream use something similar to use the tide for electricty, Same for any coastal city that has tides.

Where its is windy use wind farms. Where it is sunny solar power generation.

And we need safe cheap nuclear power. What soured the US on nuke power was every stinking plant was its own design plus the fact that every dfay design changes were mandated which pushed back completeion times.

Dont forget that you have the NIMBY types who dont want it where they live.


There are some what I call sci fi solutions. Such as Solar colectors in orbit beaming back power as microwaves, And the big mirror hitting a collector and using it for steam power. And the fusion reactor which I think is a pipe dream.

Feel free to debate these ides on there own merits, Not beacuse you call each other PHUDS

Record high levels of pack ice at the poles this year.

Them Polar Bears wont drown this year

Sorry to burst your bubble, but even the sun is an engine. May not use a 4 stroke piston in cylinder method, but still an engine. And even a turbine to extract power from flowing water or air is an engine. The definition of engine is much broader than the thing in a car.

Hate mail. Flaming.

Is that 40 miles one way or round trip? I ask because I dont think many employers would let you charge your car off of thier dime.

I challenge that assertion.

Voltaic cells... have only just got past the point were they generate more power over their lifetime than it took to produce them...

Brilliant. So garbage which requires the extraction of fossil fuel to make because the fossil fuel (oil) is incorporated into the garbage is a renewable source. Never mind the transportation of this garbage or the energy needed to originally make it, or the transportation of the workers to the plants that make it, we will just call it renewable and the world is fine. Brilliant. I just love the thinking of people who just want to feel good, wave their arms and say "make it so". No wonder people refuse to understand the actual situation we find ourselves in, if the models are correct.

Ridiculous.

If you burn it it is fossil fuel.

Oops. I used the wrong units for the Nissan Leaf's battery. That should be 80kWh, and 85kWh for the longest-lasting battery available in the Tesla Model S, not kW, but you knew that already. ;^)
