If you want your hiking boots not to become wet, saturate them thoroughly. Here is one recipe of impregnation: * 40 weight parts of cod-liver oil; * 10 weight parts of wax; * 3 weight parts of turpentine. Warm up this mixture and add 20 weight parts of glycerine. Apply the impregnation on dry, clean boots. Then allow the boots to dry in the open air (best in the sun) and apply the impregnation for the second time. WARNING: Never smear your...

Why not develop the idea of bouncing information off the ceilings in data centers to increase transmission speed by up to 30 percent. The method will allow the wireless beams to have direct communication between antennas while reducing the chances of interference. The process will involve attaching flat metal plates to the ceiling to reflect the data, while an absorber material on the rack will prevent the signal from bouncing back up.

I travel a lot on business and for pleasure. One of the most popular items I bring home from a vacation is a bottle of alcohol. Unfortunately, getting the bottles home without damage can be very tricky, especially when others are handling your luggage along the way. The protective case for alcohol is a real rescue. It is made of padded, leak-proof nylon to help shield the bottle from the abuse that the bags will take along your voyage. It also has a see-through window on the front...

Travelling with a wheelchair can be difficult. The idea is to develop a foldable wheelchair wheel. Folding the wheel will reduce the amount of storage space required from 0.7 cubic feet to 0.4 cubic feet, allowing the wheels to be stored in overhead bins, car trunks and under airplane seats. The wheel will fit any standard wheelchair and will support up to 300 pounds, and the fail-safe mechanism will prevent the wheels from folding accidentally.

The world's smallest 3D printing pen will let users draw complex designs in mid-air. Designed to be comfortable to hold and easy to use, the pen will be powered by a USB port and take only a moment to heat up. The plastic filament used to create the 3D object will be inserted into the pen's upper end, where it will move through a special mechanism to reach the hot-end nozzle. The nozzle will both melt the filament and cool it down, allowing the user to draw complicated, 3D...

The Seatower turbine platform could help encourage offshore wind farming by providing a cheaper and easier to install alternative. While offshore wind farms have many benefits, their platforms are expensive to install and require huge, specialized equipment for set-up. The Seatower foundations, in contrast, can be mass-produced on land and easily transported. They are hollow, and so will float easily--allowing them to be towed to their installation site with a reasonably small...
