"the Pong iPhone Case attracts radiation emitted from the iPhone’s antenna"
No it doesn't. It may provide a shielding effect, it may even reshape the RF field around the device, but it doesn't achieve this by 'attracting' radiation.
"... in the vain hope we might get the long-awaited "one to tell your grandkids" meteor shower. "
That was last year for me - the most spectacular shower I've ever seen, easily 2-3 a minute for hours on end. Helps being away from light pollution. The moon won't help this year though.
Let's see now. A pea sized meteorite would be around 6mm in diameter, and assuming it's a typical chondrite, will have a density of around ~3.4g/cm^3. Its mass would be around 0.4 grams.
At 30,000 mph, it would have a kinetic energy of 36kJ. Compare this with the kinetic energy of a round fired from a P90, around 520J.
Just a gash on his hand?!?
I suspect its velocity was somewhat less than quoted.

In Brits build e-car friendly solar parking bay
I can confirm that, numbers as follows:
Petrol contains 34.7 MJ per litre
1kWh = 3.6 MJ (1000J x 3600s)
34.7/3.6 = 9.6kWh per litre
1100/9.6 = 114.5 litres
Unfortunately the unwashed green masses are incapable of doing calculations, so the above is neither here nor there.
