While it's still the summertime and hot showers are probably not at the top of your priority list, it's never too early to start planning for the chilly winter months. We are all for renewable energy sources here at SCI FI Tech, so we thought it would be wise to point you in the direction of this Fireball 2001 solar panel for water heaters. Simply stick it on a south-facing angled roof and watch as your utility bills plummet. Easy enough to be installed by even the most half-assed handymen, the Fireball can be connected to an existing tank or an added 50 gallon water heater. If you care more about the bottom line than saving mother nature, don't worry: not only will this save you money on your utilities, but it also qualifies you for a 30% federal tax credit, so it should pay for itself in no time. Combine this with your Skystream wind power and, if you live in Vermont, your manure energy and you'll have the greenest house in the neighborhood, no matter what the season. The Fireball is available online now for about $2,300.
