Keep in mind that you still need to <i>obey the laws of thermodynamics</i>. Those are rules startups can&#x27;t ever break.<p>The writeup I linked has a good argument against the feasibility of wireless power for a TV:<p>&gt; A typical large, flat-screen TV (eg. [42]) will draw about 60 watts. Since a TV is usually mounted in one place, some of the limitations get easier, but not all - if the TV is two feet (60 cm) from the wall, and the receiver is 40% efficient, that&#x27;s still about 80% losses. To transmit 300 watts at 0.3 W&#x2F;cm^2, one has to have a 1,000 cm^2 transmitter, a bit over a foot on each side (31.6 cm). One could make the transmitter smaller (100 cm^2, or 4 inches&#x2F;10 cm across) by increasing the intensity to 165 dB, a level that causes burns &quot;almost instantly&quot; (from Question #7), but that seems unwise. Since most power outlets are near the floor, and the TV probably isn&#x27;t, one would still have to run a cord to the transmitter. And uBeam takes 240 watts of electricity, about a dozen light bulbs&#x27; worth, and dumps it into the air for no real reason. That&#x27;s not good for the environment. Or the power bill. Or the air conditioning - all that heat makes the room hotter.
