Closet door mirrors for solar heating

Comments:

@danie1murphy It appears that we are being fed red herrings by those who are protecting their energy businesses by being misled to believe that photovoltaics is the only way to go. This is utterly false! Photovoltaics just converts sunlight into electricity at very low efficiency, much sunlight get wasted! Mirrors reflects almost 100% of sunlight and heat to whatever you use it for, heatiing, lighting, cooking, even burning a hole through a steel plate!  I wonder about fiberoptics.

@danie1murphy maybe they are assuming that we dont want solar energy simply because it rises and set everyday. It is not a question of wanting solar energy or not, it is a question of cutting down our dependence on fossil fuel, etc. We need it badly now! Or the rich will be the onlly one still able to afford fossiil fuel at skyrockiting prices..

Not all homes have North sides, no matter what hemisphere we're on. Lots of homes are built side by side or stacked to apartment buildings. Anyhow I do like your idea, it can save people with North walls/windows energy. Or South walls on the southern hemisphere.

@maggzzz10 The energy industry is practicing damage control through peddling those energy trinkets like LEDs, photovoltaics, etc to reduce revenue losses through energy conservation. The real 800 pound gorilla in energy conservation is direct sunlight by reflection to heat indoors that could smash the energy industry into a deep depression.

@maggzzz10 if you have no northern side, you can still use east or west sides anyhow. it all depends on the mountings of the reflectors. It can be done like TV satellites or on top of poles. If you can find a spot to mount at least 4 by 8 foot refector, it is going to be worth the investment. Heat generated by this humble dimension is really huge!! equivalent to your average wall heater. The closer the reflector is to your unit the more powerful it s.

foxtrot I also fantasized about removing my entire roof and replace it with an entire sunroof or greenhouse top as a second floor with normal insulated floor to keep the hot sun out but let the winter sun in all around. This is the ulitmate !
