This SPK-1 is a solar-powered kayak which removes the need for paddling it. That outrigger thing is the actual gizmo which attaches to any medium or large-sized kayak. The panels power the 12V deep cycle marine battery. And away you go.

But wait! Besides costing $1,100, what is the point of getting / having a kayak if you plan to just to sit in it? Get a rowboat! And put solar panels on your house.

This sweet looking contraption allows you to grow your own herbs, small fruits and veggies in your own kitchen! There are a million gadgets like this in every magazine (SkyMall especially), but what makes this particular growing gadget impressive is not only the design, but how environmentally friendly it is. Totally solar powered and totally cool.

There are a lot of solar powered WiFi available, but none as cheap and easy as this. The Meraki outdoor WiFi repeater is designed to work with their $50 indoor repeater that we covered in May, and is able to broadcast a signal “up to 700 feet away,” although half that might be a bit more realistic if you’ve had any experience with wireless routers. The antenna is a flat panel that has a 180 degree spread. The repeater is, of course, designed to withstand the fury of the elements, and comes with a special “outdoor” Ethernet cable. By itself it’s only about $100, but for an unreleased (but supposedly low) price you can add a solar panel and battery pack; there’s some included software designed to manage the repeater’s power so that it’ll have enough reserves to work at night and when it’s cloudy. Part of the attraction of the whole package is also Meraki’s software, which lets you regulate the public aspects of your network, and if you choose, start charging your neighbors when they mooch off your bandwidth. The kit is expected to start shipping later this summer.

This incredible project consists of a 300-story tall tower, surrounded by 624 solar panels, producing enough energy to “power 60,000 homes.” Video after the jump. Here’s how it works:

The solar panels, are a 120m2 mixture of mirrors and photovoltaics, track the sun throughout the year, reflect the energy of the sun to solar receptor at the top of the tower. Water passes through pipes at the top, and is heated enough to turn it into steam by the solar receptor, which in turn passes through a series of turbines to produce electricity.
