The coffeetable doesn't strike me as practical but I could see an insect-eating lamp being useful outside. You'd probably have the same issue as most "bug zappers" do, namely that they kill more beneficial insects than harmful/annoying ones, but perhaps it could be tuned to kill mosquitoes? A mosquito-killer that powered itself (and didn't require propane or CO2 or electricity, as most current ones do) would be pretty cool.
