Could this solve global warming if we could turn heat energy back into electrical energy, does anybody know how?

Yes, but you can't do it efficiently enough to make it viable for mass marketing.
Technically, there are many ways to do it.
One way is to hook up a Stirling (heat) engine to a generator, and then to an inverter for AC current output.
Another is hooking up a steam engine to a generator, etc..

It's expected that even after all the ice and snow in the entire world has melted because of global warming, and giant insects are terrorizing the civilians, the overall average temperature rise as compared to today's would be miniscule for power generation---between 5 and 10 degrees. If we could actually generate electricity from the "hotter conditions of the future", we could generate it today, we don't have to wait for global warming. The Nobel Prize in Engineering (there is no such thing) goes to the genuis that invents a way to generate megawattages from ambient air temperatures. There are other, and far more effective, means of dealing with excess CO2 production, which is the root cause, not a symptom.

A good thought, but incomplete. Remember, energy cannot be created or destroyed, only changed in form. Converting heat energy into electrical energy still keeps the energy on the planet, where eventually, it will again be heat. The need is to get rid of that excess energy, by only one of two ways known to us: reduce the amount of incoming energy or increase the dissipation of energy already on Earth back into space. Probably any effort we make now would be inadequate either way.
Once a process is set in motion on a global scale, it is nearly impossible to change it. Buy stock in sunblock companies.

Heat > Water > Steam > Turbine Generator

Bud doesn't a lot of energy get lost in the process and how and where do you capture the heat from.

You must first find a heat source that will deliver the quantity needed. Usually, everytime you convert one kind of energy to another, you lose 90% of the energy of the first.

Once you find this source, you must determine what it will cost to acquire/capture (i. e., use) it. It must be cheaper (or have some other better quality) than the source(s) now being used.

Heat energy can change water to steam and the steam then can turn a dynamo which produces the electricity.

One of the ways we currently use thermal energy is geothermal energy. This works by taking water that is heated deep in the earths crust, and using it to turn massive turbines, such as that in a steam locomotive. The turbine generates electricity. This would help prevent global warming by reducing the amount of carbon that is produced by the burning of fossil fuels. (This contributes to greenhouse warming.) However, there is much more to global warming than just greenhouse gases, and even more to just greenhouse gases, than just carbon dioxide.

There are 3 common techniques that voltage must be produced. precipitated, piezzio and chemical. Peizzio is generated with techniques from compressing particular crystals. This causes electrons to interrupt loose and for that reason produce a voltage. you word this a lot in lighters that don't have a flint wheel. For the chemical era, diverse resources are used to create A managed reaction which will generate modern even as in a circuit. imagine batteries. precipitated voltage comes about once you've a magnetic container, a conductor of a few style, and action between both. in case you're taking a magnet and bypass it over slightly of copper cord you'll generate a voltage. power organizations try this with techniques from putting an electro-magnet on an axel and spinning it interior a collection of coils. you could also see this bring about transformers the position the collapsing and increasing magnetic container produced with techniques from AC modern simulates action in the different set staggering coils generating precipitated voltage.

Heat has to be moving so as to turn a turbine which will result in the generation of electric energy.

In the case of global warming, this heat has to be first funnelled through something so as to accelerate it to turn turbines.

We do this all the time-----we burn fuel to produce heat to boil water to produce steam to turn a turbine to power a generator to produce an electric current.
