Why not use magma as a potential source of geothermal energy? It is actually able to power up to 30,000 homes. FYI, magma can produce dry steam at 750 degrees Fahrenheit, which can generate up to 25 megawatts of electricity. The usual geothermal well can produce 5 to 8 megawatts of electricity.

Why not create multi-account credit cards? This will eliminate the need to carry a separate card for each account. Such a card will allow a user to select the account to draw from (an active account will be indicated with a small blinking light on the credit card); it will be possible to swipe it just like a regular credit card. The card will also have the built-in battery which is good for 4 years of normal use.

Weed killing will go high-tech and less toxic with smart lasers able to recognize, and destroy, unwanted weeds. The method will use cameras and a computer algorithm to distinguish the weeds from more desirable plants. Once the weeds are recognized the CO2 lasers will deliver a carefully measured beam directly to the weakest point of the weed. The energy levels of the beams will be exact, because a beam that is too weak will actually encourage the weed to grow.
