1. Wireless electricity - Like Bluetooth. You'd be able to connect a wireless electricity transmitter to the plug socket in the wall, and run electric appliances in the vicinity without connecting them to the mains. It is really quite simple, once we have mastered the principle of Spatial Force Transmission, which is:-
2. Spatial Force Transmission - You'd be able to move objects at a distance by applying force elsewhere. It is different from telekinesis in that the absurd concept of "mind power" is not used. You would have to physically push a joystick (while sitting on the sofa), which would in turn transmit the force through the fabric of space-time to close the door of the fridge in the next room. The idea doesn't use the fictional concepts mind-power or cosmic energy, but rather relies on the solid practical foundation of Energy Credit; which... would have to be invented first.
3. Energy credit. In layman's terms- On-demand Force: There would be a universal energy ledger, which you would be able to access through an energy card, which is similar to the present day credit card. If you need more force than you can physically muster, you'd be able to borrow some, which you would then have to repay later. For example, if you needed to uproot a teak tree in a hurry, or kick a penguin into orbit, you'd be able to borrow some extra force from the Energy Syndicate, which you would later have to return to the Syndicate in many small installments by doing say, 1300 push-ups. Or by pedalling the flywheel of a generator for 3 hours. You might have to pay an interest on energy borrowed, i.e. doing more push-ups than the energy-equivalent of which you borrowed. There would be an energy stock market, and you would be able to trade in energy futures and options. People would speculate on volcanoes and Supernova explosions. Obesity and winters would trigger a recession. But then, you can figure out such trivial matters for yourselves.
You would also be able to lend/borrow time this way. If, say, you want to save time on your commute to office, you can borrow time from yourself. Your hour long commute would be over in a second, but to compensate, you would have to sit idle at home for an equivalent amount of time. There would be time-hedge funds and futures markets, where people who anticipate hectic activity would be trading in time-shares with idle people. Market sentiment and hence the price of the shares would be affected by the forces of demand and supply. Idle people would be in much demand, and hence be paid hefty sums of money to sit around doing nothing. Increasing economic activity would mean more work, and hence more demand for idlers and bums. This would go on until the world reaches a state of frantic industrial activity, where production and business undertakings would reach a state of frenzy, and the person who can do the least amount of work would be paid the highest salary. There is nothing in contemporary economic models that prevents elements of unintended consequence to apply to non-stochastic mathematical frameworks. Besides making me and an old comrade of mine the wealthiest people in the world, it would also serve to establish the exact money value of time. Just how much will a busy man pay an idle man for time before he runs out of marginal utility. In this case, that would be the market value of time as determined by the classical economic forces of supply and demand.
5. An interesting application of Force credit would be paid-weight losers. People whose job it would be to work out and lose weight on behalf of obese people who would pay for such weight-loss services. Relevant pricing models would apply. Blah. Go, figure.
6. Invisible trains. Now who wouldn't want those? As a population control solution, it is far more effective than contraceptives. Less clumsy than contraceptives. And going by the general public's awareness of train accidents at unmanned intersections, more discreet too. What's more, for it to be effective on a large scale, it doesn't need expensive and unnecessary media and press publicity. Au contraire, the less publicity it gets, the better it works.
7. Teleportation. But you had already thought of that, hadn't you? If you've never, ever wished to be teleported, I would like to meet you. And get your autograph. Because on a percent basis, you belong to a group more exclusive than the Apostles.
Some of these developments may seem out-of-the-ordinary. Some may even go against the grain of common sense. But if you think about it, the idea of attaching an ox to a peculiar model of furniture went against all common sense in mass-transportation. If you ask me, on a fundamental level, the question of What is more important than the question of How. What is the question we have to ask ourselves. How will inevitably follow. It is a lesser task that can be figured out by technicians and engineers.
And once the How is achieved (of course by lesser tactical minds who merely follow our broadly outlined "what" strategy), the next question for us to ask is "How much for a dozen"?
In my opinion, if you figure out whether to manufacture it in China or Taiwan, the rest neatly falls into place.
I should be made the President of the world.
