Electric car efficiencies

Nor is there any need for warmup time or idling in any well-designed IC-engined car. Yes, people do it, I suppose from a mixture of habit and ignorance, but what do you want to bet that the same people who idle their gassers today would look for ways to warm up & idle their electric cars?

Renewable energy has virtually no pollution, no spills, no explosions, no collapses, no radiation, no excess carbon dioxide, needs no military defense (the USA spends much more than ALL the other countries in the world COMBINED on our military!), and renewable energy is distributed almost everywhere on earth, so no one person, or one country can control it.

Far from being entirely true. Many forms of renewable energy DO pollute, and have spills, collapses, and so on. Military defense would still be needed, first because oil is a very small factor in the current military situation, secondly because some proposals, like the one for providing Europe with electricity from solar generation in the Sahara, would be even more vulnerable to disruption than current oil supply chains.

In addition, virtually ALL of the benefits of pure electric cars also apply to PHEVs, while few of the drawbacks do.

I spilled wind from my sail and lost the race. Good thing the EPA wasn't looking.

As well it should. Shouldn't that energy go to African nations first?

Like manufacturing jobs go to the US?

It's even easier with an electric car, you set the timer to preheat your seat and when you come out to the car your seat and steering wheel are warm, windshield is defrosted and less energy was used then a gasoline cars block heater.

Someone has to pay to put up the PV panels, and it's not like there's going to be any less sun for the African nations.

you should turn yourself in.....

For those of you still think that global warming is about science and not politics here is a little document that was circulating at the climate conference in South Africa a few months ago. This document details what the global warming supporters at the U.N. want to see happen. Pages 13-16 are most enlightening. Among other things this document seeks to:

1. Require a wealth transfer from the West equal to their entire yearly military budget to the U.N. for use in fighting global warming and paying off other nations (note that the code phrase for the West in the document is "Annex I Parties").

2. Requires the complete elimination of all military spending in the West

3. Establishes a Climate Court with jurisdiction only over the West to ensure that the payments continue to flow.

4. Establishes the rights of "Mother Earth"

When you see anything from south africa assume it is a scam, this is no different.

Germany already is getting >20% of their electricity from renewable energy. Germany is about as sunny as the State of Washington. They are planning on getting 50% very soon and 100% by 2050.

Wind scales up. Solar scales down. Wave power is available on many coasts. Tidal power is also very possible especially in bays. Biogas / methane can be made from sewage and farm waste. Small scale hydro can be done in all the existing dams. Geothermal can work in many places, and we can drill to get it, as well. We could have about 10X more power than we need from all these sources.

Dave Cloud's Dolphin goes 200 miles on lead acid batteries. The Illuminati Motor Works 7 goes 210+ miles on a ~33kWh lithium pack. The SIM-LEI goes ~207 miles on a 24.5kWh pack; similar capacity pack to the Leaf. The Tesla S goes up to 300 miles on an 85kWh pack (if I recall correctly), and the DBM Energy Kolibri 99kWh lithium metal battery took a converted Audi A2 375 miles @ 55MPH and had ~18% of the charge left.

Both the early Aptera and the Edison2 VLCe show that <100Wh/mile is possible. The SIM-LEI uses ~134Wh/mile, and the Illuminati 7 is ~160Wh/mile and Dave Cloud's Dolphin is about 164-170Wh/mile.

For comparison, the Nissan Leaf is 340Wh/mile which translates to 99MPGe. The Dolphin and the 7 have the equivalent of 1 gallon of gasoline in their packs.

Now thats a test, a realistic speed and they didn't run the batteries down to nothing.
I hate it when EV makers post 100 and 150 (or some 3 digit number) and you have no idea how they got those numbers.
One can only guess it normally involved speeds around 35mph, flat roads, no stops, no heat or A/C and they ran a brand new battery pack to the point where it would not move the vehicle any more, so on and so forth.
