It sounds cool to do all these space missions and build giant solar arrays to beam power to Earth, but I think it's more practical and cheaper just to throw some solar panels on rooftops and windmills by houses and across the midwest.

Home based power is reliable and available now, with no transmission losses. With the right loans, marketing, and government investment, people could just swap their electric bill for the loan on their personal power plant and voila, clean power to the people at virtually no cost. It would also create jobs as solar and wind plants spring up to fill the demand.

Stop building dirty coal and oil plants and start investing in solar and wind.

well if they had some space age, heat resistant pipes to shove down there into the magma, then run some liquid through the pipes to transmit the heat to a steamer, we'd have delicious vegetables in no time. i mean geothermal power. large scale geothermal.

it'd be pricey to make the first one, but it could be a big player in renewable energy. and unlike solar panels and wind mills which are like socialized energy because everyone controls the production, this could be a major central project for a greedy corporation.

then before you know it they drill to deep and there's a balrog running the streets.

Similarly, Logo can be a great way to educate programming skills, as well as artistic and problem solving skills. Logo can make spirograph-type art, and puzzles such as mazes can be navigated. I'm not sure if Logo has been developed as far as having AI, but it seems possible.

Logo may be more appropriate for younger audiences. Something with a similar artistic/programming approach for teens would be interesting. Maybe sodaplay or processing, although these maybe a bit too difficult.
