Super Soaker Inventor Hopes to Double Solar Efficiency

mattnyc99 writes "With top geeks saying photovoltaic cells are still four years away from costing as much as the grid, and the first U.S. thermal power plant just getting into production, there's plenty of solar hype without any practical solution that's efficient enough. Until Lonnie Johnson came along. The man who invented the Super Soaker water gun turns out to be a nuclear engineer who's developed a solid-state heat engine that converts the sun's heat to electricity at 60-percent efficiency—double the rate of the next most successful solar process. And his innovation, called the Johnson Thermoelectric Energy Conversion (JTEC) system, is getting funding from the National Science Foundation, so this is no toy. From the article: 'If it proves feasible, drastically reducing the cost of solar power would only be a start. JTEC could potentially harvest waste heat from internal combustion engines and combustion turbines, perhaps even the human body. And no moving parts means no friction and fewer mechanical failures.'"

    Well, if he's oxidizing his hydrogen, I'd have to say he's all wet.

    The higher the technology, the sharper that two-edged sword.

    Energy efficient photovoltaic cells is fun and all, but clearly he's better qualified to invent nuclear powered Super Soakers.

    And I think I speak for all of the geek fraternity when I say we'd prefer them over some poxy solar panels.

    The upside is that- like the Super Soaker- these panels will be far more efficient than their weedy predecessors.

    The downside is that- like the Super Soaker- they'll only be available in eye-searingly garish combinations of purple, red and fluorescent green and yellow.

      And, also like Super Soakers, this will spend all its time outside in the sun, and the colors will thankfully fade -but only on one side.

    This is probably going to dent my karma, but what the heck:

    JTEC could potentially harvest waste heat from internal combustion engines and combustion turbines, perhaps even the human body. With this we can find all the power we need, the plan is to harvest humans, makes the Matrix look almost almost prophetic :)

    And as for location, there's no place on earth where the rainfall would possibly exceed the needs of a densely packed urban population, without conservation.
