Venus has water. All we need to do is sequester the CO2 and drop the temp a bit. Somewhere between 440-455 degrees C do it. LOL Mars has lots of CO2, yet it is cold. Scientists say they need to manufacture hydroflourocarbon's from the rocks to terra form Venus.

Rats should avoid bisphenol A. However, it is safe for your grandchildren. Baby bottle chemical levels safe, EU agency says Last Updated: 2008-07-23 14:07:33 -0400 (Reuters Health) MILAN (Reuters) - The amount of the controversial chemical bisphenol A (BPA) found in baby bottles is tiny and cannot harm human health, the European Union's top food safety body said on Wednesday reacting to recent health concerns. Earlier this year, a heated debate over BPA safety sparked in the United States and Canada after various studies involving laboratory rodents suggested that even small levels of BPA - used in products ranging from baby and water bottles to beverage cans - can be harmful. A scientific panel of the European Food Safety Authority (EFSA) has looked into how people metabolise BPA and concluded that tiny amounts of the chemical to which humans are exposed leave body quick enough to cause no harm, EFSA said. "The conclusions of the panel are that after exposure to BPA the human body rapidly metabolises and eliminates the substance. This represents an important metabolic difference compared with rats," EFSA said in a statement. Responding to worries about babies' health, EFSA said newborns were able to metabolise and eliminate BPA at doses below 1 milligram per kilogram of body weight per day - even above the Tolerable Daily Intake (TDI) of 0.05 mg/kg/bw a day. "Exposure of the human foetus to BPA would be negligible because the mother rapidly metabolises and eliminates BPA from her body," said the agency based in Parma in northern Italy. In its previous BPA risk assessment in 2006, EFSA set a TDI of 0.05 mg/kg/bw based on the no-observed-adverse-effect level of 5 mg/kg body weight/day for effects in rats and included an uncertainty factor of 100. "In this latest assessment, the panel concluded that this TDI provides a sufficient margin of safety for the protection of the consumer, including foetuses and newborns," EFSA said. The agency said the significant differences between humans and rodents in the way they metabolise and eliminate BPA "limits the relevance of low-dose effects of BPA reported in some rodent studies used for human risk assessment." EFSA said it would monitor closely scientific findings regarding BPA and any related health effects. reutershealth.com

To colonize Venus, I think the earthlings need to construct a huge-huge solar panel array and place it in orbit around the planet so that it can produce some power, but more importantly shade the planet enough so it quits cooking quite so much. That would make it easier to stabilize the atmosphere. The panel may have to be constructed as a big ring around Venus since it would be difficult to maintain a static position between Venus and the Sun, but maybe the solar energy could be used to power some sort of active arangement to keep the panel in place. We can ask Winston Rumfoord if it will happen. TP
