2 3D printer that consumes supermarket plastic bags E-mail
3 Simple classroom app for smart phones and computers. Teachers are given an application that allows them to quickly access, edit, and scramble the roll of their class. Also allows for automated emails to be sent on command to principals & parents. E-mail
4 Create a night light that senses the other lighting sources in your room. For example when you turn off your bedroom light, it comes on for 60 seconds then dims to off. This gives you time to find your bed! Interior lights in cars can already do this. E-mail
5 New design for a smart phone: transparent body to look interesting, full touch screen, and USB connections to a computer and to a pen drive. E-mail
6 To protect against loss of power to a nuclear power plant, use a water tower. Gravity can force cool water through the reactor until power is restored. E-mail
7 Walkie talkies that have a fully functional navigation system with a screen that shows the position of other walkie talkie users. E-mail
8 Aerogel made of rice husks for insulation and other applications: Green Earth Aerogel. E-mail
9 Unarmed remote control aircraft seem to have unlimited potential. Mounting cameras on wingtips and front and back would enable stereoscopic vision. Depending upon mission, additional sensing capabilities should be added. E-mail
10 Put soluble orange dye in the alcohol hand gel used in hospitals by staff and visitors. Then anyone not using it would be identified. It would wash off easily on leaving hospital. E-mail
11 Tiny CCTV cameras in cockpit of plane connected to a multi-channel digital video recorder. Store the hard drive in the blackbox. If the plane crashes, full audio/video recordings of the crew and instruments, passengers, & out-of-windscreen view. E-mail
12 Heavy buckets of water are very difficult for older people to carry. The manufacturers should add removable wheels so that the buckets can be rolled, then lifted. E-mail
13 Paper used for shopping bags is to be replaced by cotton bags (old fabric rags, etc). E-mail
14 Liquid nitrogen airplane. Instead of kerosene, fill tanks with liquid nitrogen, which vaporizes through nozzles to propel plane. Safer since no fire danger; lighter since no jet engines; no air pollution; no noise pollution. Or use compressed air. E-mail
15 Save life by donating a kidney to a stranger. You may trigger a "domino transplant", in which several donors who were willing to give a kidney to a relative, but were immunologically incompatible, give instead to a stranger. Thus, many lives are saved. E-mail
16 Pet rental: service to rent dogs, cats, and other pets to people for an hour, a day, a week, or longer. This would let people decide whether they like and can handle pet care and would reduce abandonment. E-mail
17 Stores should have a small strip of one-way mirrors around the inside, where an armed guard could hide, even if a robber knew he was there, somewhere. A thief couldn't take hostages since he wouldn't know where the guard was (he might be behind him). E-mail
18 Banks that are "too big to fail" threaten the world economy if they do fail. To prevent banks from getting so big, government should force breakups or block mergers of banks/companies with assets or liabilities > 1 day of world GDP (0.3% of annual GDP). E-mail
19 A spiral slide as a fire escape from tall buildings. It has a cover and may use seats (& seatbelts) on gears (to regulate speed). It goes 10 floors at a time. Access via metal, locked doors, opened only in an emergency. Faster than stairs. E-mail
20 Companies charge huge fees to workers who migrate abroad for long-term contract jobs (as maids, construction workers, etc.). Instead, governments should arrange migration and contracts at low cost to let workers keep more of their meager incomes. E-mail
21 People are setting up a Twitter account to raise $1,000,000 for charity. Can they do it? See or TwittaCause. E-mail
22 If you want to wake up early in the morning, then before going to sleep say 100 times the time when you want to awaken. E-mail
23 A house phone (landline phone) with an mp3 player, ring-tones, and ring-backs. (ringtones, ringbacks, land-line) E-mail
24 Digital vehicle traffic accident recorder: a small, digital camcorder mounted into vehicle front grill would record for 30 seconds, allowing visual recall of collision causes. E-mail
25 Bluetooth spectacles: Often one forgets where one put eyeglasses, thus add bluetooth to eyeglasses so that they could be pinged and made to beep to tell where they are placed. E-mail
26 Lollipop cough drops: to prevent choking on normal cough drops that might be inhaled when sucking in air before a cough, cough drops could be made as lollipops with paper or plastic sticks or rope loops. E-mail
27 Help people who live in trash dumps by employing them to run recycling machines. (Garbage, junk, recycle, poverty, scavengers) E-mail
28 Vending machine manufacturers should program their vending machine dispensers to rotate past 360 degrees, like 380 degrees, then go back 20 degrees to a neutral position so that your chips or candy will fall down every time. E-mail
29 A car company could partly fund development of a non-fossil fuel car, the world's first that would be mass produced, by collecting $2000 deposits from 500,000 people, who'd suggest features of the car. It would cut greenhouse gas pollution. (Wikicar) E-mail
30 To help poor people who can't afford the high price of staple foods, we can reduce food prices by cutting demand for food. Let's all eat less rice and other grains and especially less meat, which requires much grain to produce. E-mail
31 Pet water fountain for dogs & cats. It would look like a human fountain, but it would have a paw lever. The animal would put his or her paw on the lever, and the fountain will give water. E-mail
32 Meter to monitor power usage (watts/amps) per outlet. Variation to be uses at circuit (fuse) panel to trace hi-use circuits. Could be simple analog or digital/programmable to compute cost of use. Could be separate attachment or built into outlet/breaker. E-mail
33 To increase lending, better guarantees are needed. Personal guarantees can be dictated as videoclips, perhaps notarised. Personal guarantees address the problem of no title books. In traditional societies, guarantors' assets are well known. E-mail
34 Escape from building fires. Once people are trapped in storied-building fires, a self-contained rope platform can help people evacuate from upper windows quickly. E-mail
35 Mobile phones should have an internal electricity generator/accumulator just like the "kinetic" wrist watches. E-mail
36 A Controlled And Effective Education System For A Country: The future of a country depends on the abilities of the young generation. It is the responsibility of the country to identify and enhance skills of each person to gain optimum output from them. E-mail

39 Use a new word to describe the role of a spouse or boyfriend/girlfriend: FROLO, or FRiend, ROommate, and LOver. E-mail
40 Auto rotation of photos. Photos taken in vertical position are actually stored horizontally. To view on computer you need to rotate them. Cameras can use mechanism like spirit level to record camera position and rotate photo accordingly. E-mail
41 Fast food chains should include one helping of vegetables in all their burger and other menus, for example, disguised as finely chopped vegetables added to the burger or more salad into the burger beyond the lettuce leaf! Roopa Karkhanis E-mail
42 People who are determined to kill themselves should do so in a way that their organs can be donated and save the lives of others. (suicide)

44 The parent-child divide can only be bridged if parents show they care for their children, keep open the channels of communication with them, and provide them with a companionship close enough to counter the unhealthy peer pressure often acting on them. E-mail
45 With >6 billion people on earth now, and ~30 billion in human history, don't you think we could find 50 or 60 of the brightest to figure out a way to eliminate the need for wars altogether? Maybe a permanent UN council? E-mail
46 A successful and happy marriage needs to be built on a foundation of COMMITMENT, CARING, COMMUNICATION and COMPANIONSHIP. Then add a superstructure of LOVE and LAUGHTER. And keep in mind, your happy marriage is a legacy of happiness for your children too! E-mail
47 When a 17 year old child gets a driving license, allow him to only operate cars fitted with GPS monitors to record where they are going, and how fast they are going. Monitor is merely a cell phone equipped with GPS system. Perhaps $250 for 6 months. E-mail
48 Poor people are always engaged in, mostly, physical activity and do not get good and adequate food. We can have community kitchens, run by rich people/organisations, so that poor are free from the worry of food. There is enough charity available. E-mail
49 Heavily populated nations such as India face water on roads, canal jams, and mosquitoes. A solution is to construct drainage canals in a V shape so that the canals will not store mud and thus water. There would be free flow in canals and fewer mosquitoes. E-mail
50 Instead of fuel wasting thick-walled pressure cookers with lids needing to be locked on, we can use much thinner-walled cookers with variable weight pressure-liftable lids, to save fuel and preclude excessive pressure build-up and vessel bursts. E-mail
