Is Earth a closed system? How does one add/remove excess thermal energy?
With our current reliance on fossile fuels and other forms of stored energy (coal, chemical) we are releasing excess waste heat (among other things) into the atmosphere. Looking for alternative ‘green’ energy sources is a great ideal, but my feel this could further impact the environment.
Assuming for argument that we can build a large mirror array in space and send captured solar energy safely to earth. That amounts to a new input of energy into our (closed?) system. How will we deal with the excess heat generated as a by product of doing work with that energy? Is there a way for us to efficiently radiate that heat into space?
ha ha i thought about that, ‘why not build giant solar panels in space to block off the sun, since our polar ice cap just isn’t cutting it anymore’. we dont have the technology simply put.
theres probably a huge matter of safety in transfering the energy if it was possible.
we need to focus getting heat from the sun away from our planet as it is. worrying about substituting energy wont help us at this point.

The Solar Fraud: Why Solar Energy Won’t Run the World, Second Edition $23.95 Solar energy has its uses many of them but running the world isnt one of them. Solar energy has always and will always provide some fraction of the worlds energy budget. The question is how much? By and large, that fraction has been on a steady decline not just for decades, but for centuries. The Solar Fraud presents the physics behind the hype, explaining why the problem is not technolo… |
