Because what GP is proposing is thermodynamically impossible. The second law of thermodynamics states that heat naturally flows from hotter to colder regions. You can't just magically convert a static pool of heat to light and beam it somewhere else with no energy input. It's like suggesting that we generate electricity by rolling stones uphill; it just doesn't make sense.
