VERIFIABLE STATEMENTS

Logical Positivists held that statements that make no difference to anything have no content. Only verifiable statements are meaningful. The advertising slogan “Put a tiger in your tank” is an effective metaphor, but has no meaning empirically

If it were easy to get CO2 to react with H2 economically -- without putting in more energy than we get out -- then we would have done it by now. That would be a huge step to solving the world’s energy problems. Imagine it: mimic photosynthesis to split water, releasing H2 and O2. That’s been done, and could potentially drive a hydrogen economy. But there are practical draw backs to a hydrogen economy. How much better to react the H2 and CO2 from the air to make natural gas or even synthetic gasoline! Then we can go right on burning gas in our power stations. That would balance CO2 emissions with CO2 capture, halting the rise in atmospheric CO2 levels and relieving our dependence on fossil fuels. Energy security. The returns could hardly be greater, and yet we have still not succeeded in driving this simple reaction economically. . . . Page 114
