Microwave home heating Printer Friendly Version
Hot water pumped through radiators is how many houses are heated, right? The water is heated in a boiler using electric or gas burners.... Well how about heating the water using microwave... if it's cheaper to heat a cup of water in a kitchen microwave oven, rather than on a gas or electric stove, then surely it's cheaper to heat the house boiler with a specialy designed microwave thing.
Reward: Fame and fortune.

Cool pillow Printer Friendly Version
I find I sleep much better if I have a pillow that stays cool to the touch even if I have been resting on it awhile. I also hate that pillows become lumpy so quickly. It would be good if someone could make a pillow out of gel or the like that had chemical properties designed to keep heat away from the head and also resisted lumping.
Reward: two free pillows so I could finally sleep

Sound Filters for Open Windows Printer Friendly Version
I want a sound filter for my windows. With all those smart people out there on the internet, it can't be so hard to make one. The sound filter works much like the mosquito nets I already have: It's cheap and you fasten it on the outside of your window. It'll keep out all the street noise, but it will let in the fresh air, which is especially good in summers.
Reward: I want sound filters for ALL my windows.
