10 Innovations that change your lives
The Hydrogen Economy

Meanwhile, the only byproduct of the combustion of hydrogen is ... more water! However, hydrogen storage remains a thorny issue, due to its low density, and hydrogen may end up being only one of many interlocking components that replace the current oil economy.Therapeutic Cloning

The whole idea behind cloning all along has been to grow replacement organs or tissue in a vat, which the body would see no reason to reject. Cancerous or damaged organs could be replaced by new, disease-free clones of themselves.Moore's Law Upheld

For at least two decades pundits have been pointing out barriers to the law's fulfillment, and the chip industry has been smashing those barriers. Currently they can't agree if the law has a couple of more decades of life left, or 600 years. Either way, in terms of available computing power, it's clear that we ain't seen nothing yet.Desktop 3-D Printing

The next step will be to design your own gadgets, post the designs, and sell them, etc. Toys, kitchenware, and decorative household items should be fair game, at least. Cottage industry, here we come!Location-Based Computing

As well as servers with Internet address, there will be servers with geographic coordinates.
Better, Cheaper Solar Cells

In less than ten years the cost of solar energy could be at parity with the cost of electricity from the grid, and solar cells could be standard features in new residential construction. Your house could power itself about a third of the time. (Science can't do much about night and bad weather.)Mobile Robots

Why drive to the deli to pick up your order when you can just send your car? We may see convoys of robot trucks on the highways. Admittedly, they'll probably have more initial acceptance in warehouses, handling pick-and-pull chores.Pervasive Wireless Internet
Credit: AppleWiMAX, 3G, 4G, etc., all point to a pervasive wireless Internet, where being on-line everywhere, all the time, will be routine. That implies the possibility of full connectivity between any two random devices. Want to check your burglar alarm from your cell phone? It'll be easy. Unjacking to get away and relax, however, may not be so easy.
