Take each paragraph and jot down the most important point(s) in it. For example: An air-powered car? It may be available sooner than you think at a price tag that will hardly be a budget buster. The vehicle may not run like a speed racer on back road highways, but developer Zero Pollution Motors is betting consumers will be willing to fork over $20,000 for a vehicle that can motor around all day on nothing but air and a splash of salad oil, alcohol or possibly a pint of gasoline. becomes: Zero Pollution Motors is developing an air-powered car that will cost $20,000 and run all day on nothing but air and a bit of salad oil, alcohol or a pint of gasoline. Do the same for each paragraph. Now you'll have a condensed version and, more importantly, it will be in your own words. Then shorten ever more, if possible.<br><b>References : </b><br>writer Best way to do this assignment is to break it down into bite-size pieces.

Tons of research has also been done on converting wave energy from the oceans into energy. And research has even been done into flying kite-like systems up into the jet stream to collect wind energy. The coolest that I've seen is research that is being conducted to create tornadoes and use the wind energy from the tornado to create power.<br><b>References : </b><br> Yes, there has been research that has been done into taking satellites and using the solar energy they gather and converting it into microwave energy that can be beamed down to earth.

It costs something like well over $10,000 to get a kg of material into orbit. A quick look here: http://www.energyenv.co.uk/SolarModulesMain.asp 27kg for a 240W panel costing £900. It would cost something like £180,000 to get it into orbit right now. So you've increased its output by a lot, maybe a factor of 10 compared with being on Earth. But you've increased its cost by a factor of 200 or so. And on top of that you have other material - like a way to beam down the power, a frame etc. Eventually, with cheaper launching tech and much thinner panels, solar power stations in space might be a good idea!<br><b>References : </b><br> The technology IS available, it’s just expensive.

It may be not far off however as some of Tesla's theories may be made to work in the future. Even a huge high powered magnifier of sun light may be used to focus in on a steam generator to make steam to power the generator.<br><b>References : </b><br>Reading Your question is a good one but at the present time the technology is not available.
