Powerless Inertia propulsion craft Printer Friendly Version
Nowaday, The US has the most sophisticated spacecraft. But it hasn't ever developed a transport that can use very little energy.
To overcome the grativational force of Earth, people have to apply a lot of thrust to encounter it to go to space.
But why don't we try to change things around? I believe (although seems impossible) there are two methods to propel the rocket without fuel.
First, scientists can find method to stop a tiny area's gravitational force, then we can just a apply a tiny force to push things up since net force is zero.
Second thing is to stop a tiny area on the Earth to stop rotating suddenly. Due to inertia, the rocket in the specific region will start to move with the Earth rotation speed (A HUGE ONE!).
Personally, i feel that the second is pretty cool.
Reward: Let me be the one who ride on this rocket. Invite me to research in these things.

Entrepreneur's Business Park Printer Friendly Version
Every area has talented people. Skills all going to waste. Dying of loneliness. And lack of opportunity. In my experience, the only people who really benefit from the agencies set-up to help entrepreneurs, are the employees who mostly do very little to actually help alleviate their struggles.
So why not introduce a true enterprise zone to help bring enterprising people together. Government funded, industrial type building - you're allowed all kinds of styles in business parks! It could be a sort of theme park for adults, with places to crash out, bars that serve good food/drinks, IT stations, art studio facilities, noticeboards, keep fit equipment including fun stuff like swings, a gym for people to play ball games etc., and most importantly, a large conference suite so that council members or big business can consult the brainy bods!
Surround the place with loads of trees, flowers. Create enough parking (could be underground). Maybe charge members an annual fee, reimburseable if they make a good contribution to help run the place efficiently/cost effectively.
For ambience, try using weatherboarding on the floor - nail down and sand the panels, apply paint/varnish! Cheap, effective, hard-wearing. Don't make ceilings too high or problems keeping place warm. Could show educational films relating to art/craft/design. Hold seminars about whatever people are interested in, e.g. tackling poverty... Could run a store re-using waste paper etc. There's so much potential, the mind boggles!
Reward: Just make it happen! Invite me along to my local think tank. That would more than suffice.

Convertible Knitting Needles Printer Friendly Version
For those of you who don't knit, let me give you a brief description of the problem. Knitting needles are not just the two sticks normally associated with the craft. Knitters also need five double pointed needles, circular needles (two needles connected by a string), and occasionally a pattern calls for a crochet hook, as well. This can get rather annoying, especially if the nearest supply store is 30 miles away.
So, instead of an ever growing pile of knitting needles, how about interchangeable pieces that screw on and off of a set of base sticks? For example, if I want to shorten a set of regular sized needles, I would just unscrew the lower parts of the needles and replace them with a shorter end. Let's say that a pattern calls for a circular needle part way through. No problem! Just screw on the ends connected by a string.
Reward: A set in every size
