Billions of Li-ion AA batteries in cars will be a
recycling/disposal nightmare. We need nuclear powered cars and trucks. Global warming is only the tip of the iceberg, the whole solar system is getting hotter. Jupiter has a new Red Spot, Mars ice caps are receding and the Rovers are getting considerably more power than was predicted. Even Pluto is getting hot, up to several degree above absolute zero now. Maybe we now know why the ancient Egyptians worshiped the Sun. "Edward A.

Unless you park it for a few weeks between uses, solar cells don't come close to providing enough power to make it a viable charging option. -- Jim in NC |

You do the math. -- Jim Pennino Remove .spam.sux to reply. |

Or perhaps you charge batteries in the house on good weather days, and then transfer to your car at night? Sunlight (with losses) Solar panel on house (with losses) Battery in house (with losses) Battery in car (with losses) motor. This is pretty green? How many good weather days will it take to drive to work once? Al G |

![]() http://www.pubs.royalsoc.ac.uk/media...pa20071880.pdf suggests the sun has no effect on climate. Or, that we we cannot presently correlate sun and climate. Or there is some interfering data swamping a comparatively small effect. If not the sun, how about our dirt? It lives, excretes, and is deep, to boot. Who understands zero gee fission? we are ice on a fireball. We are the snowball surrounding hell, walking around on a little insulating frozen rock floating on a lake of magma. Cheap renewable power? Geothermal, solar steam, wind, tidal. Real expense? Transmission, overpopulation? Private planes to eliminate highway congestion? The highway, be it asphalt or air, is no more than an extension of the parking lot. Are we gonna have sky garages 20 floors tall and elevator parking for excess idle Mohler sky machinery, or are we gonna take air taxis? How many pedestrians squashed by crashing cabs before we try dirigible busses, or living with parachutes in our office? I see city buildings before commuter conveniences. Land is limited. I see deep wells for Icelandic power, even air conditioning. I see tube trains surrounding volcanic artifacts linking ring of fire hot spots. I count the calories produced by cities in their warm spots with their reflective sky scrapers and steam pipes warmed by moving lightweight reflectors. I see wind power to produce compressed air, liquid nitrogen and ultimately, hydrogen to be burned on site to put power into the grid when needed. Can liquid nitrogen be used to operate a Stirling cycle engine or turbine warmed by ambient air? What is it's energy density next to gasoline or hydrogen? What about it's seasonal efficiency? Our oil problems are really political marketing. Terry K |

This paper refutes the above paper: http://scienceandpublicpolicy.org/im...e_lockwood.pdf And this paper too appears to have some flaws. It ignores the Pan evaporation rate which has shown the amount of energy from the sun reaching the earth's surface has been going down for decades. Also it denies the major effect of CO2 while current scientists have overwhelmingly accepted CO2 as the prime driver. Still in the end the ONLY source for earth's energy we see does come from the sun with the exception of a small amount of leakage from the earth's core. Both papers have some serious conflicts with today's accepted theories. Roger (K8RI) |
