At a very cursory count we have 30 million vehicles
in the UK, most have roof which gets hot in sunlight.
The Refecto-top will reflect the sunlight back where it
comes from, about 152,000,000 m2, if everyone used
one.

So that's 1.5e8 out of 5e14m2. |

Doesn't sound much, but if you start with Actual Physics and
work out the proportion of solar energy that ought to be
retained by our extra 0.02% of atmospheric CO2, it's not that
far out. |
|
| |
Ah, and there's a billion cars worldwide, so even better. |
|
| |
What proportion of the reflected energy makes it back out of the ecosphere ? |
|
| |
Virtually all of the visible light will. |
|
| |
Yes, but that's only a narrow slice of your primary's emission spectrum. |
|
| |
Cost/benefit; will the energy consumex by manufacturing and installing the reflectors equal or exceed the energy reflected in their service lifetime ? |
|
| |
Who's going to keep them clean and polished ? Wouldn't PV panels be a better investment ? |

We're talking about global warming, [8th]. Practicality or
usefulness is not a prerequisite. |
|

So, my idea to paint myself with white paint
might be so useful after all? Scratch one
patent...wait...I might be able to flog it to the US
navy. |

What sort ? Idiopathic or anthropogenic ? |

|

Ah, right. Alleged anthropogenic ... |
