Leijerstam used a modified version of the commercially-available Sprint trike, made by recumbent tricycle manufacturer Inspired Cycle Engineering (ICE). She chose to go with a recumbent trike because it would allow her to maintain stability in the often very-high winds. This allowed her to concentrate simply on moving forward, instead of having to waste time and effort keeping her balance. The strategy paid off, as she not only made it, but also beat two other cyclists who had set out for the Pole on two-wheelers, days before her Dec. 17th start date.

It just kept going and going: Renovations at a Los Angeles restaurant in February uncovered a neon light, hidden inside a wall, that had been was switched on in 1935 and left burning for 77 years.

The walls of the restaurant featured numerous hand-tinted transparencies of mountain and forest landscapes, each of which was backlit by a rectangular neon light. One such light was installed in a window-like nook in a basement restroom, where it softly illuminated a woodland scene.

In 1949, the nook was covered over with plastic and plywood when part of the restroom was partitioned off as a storage area. But for some reason, workmen never got around to disconnecting the electricity. For the next 62 years the illuminated tubing was hidden within the wall. Meieran estimates that the neon tube has racked up more than $17,000 in electrical bills.

A toy company has designed building blocks that make it possible to combine multiple brands, from Legos to Tinkertoys.

A toy company has designed building blocks that make it possible to combine multiple building block brands, from Legos to Tinkertoys.

By downloading free designs and using a 3D printer, you could have your very own pieces to connect ten different brands of building toys to each other and construct even more elaborate contraptions and structures.

As the first commenter on the webpage noted, “This is the next singularity.”

The problems of making both wind and solar power practical sources of electrical power on the grid.

The difficulties making both wind and solar power practical sources of electrical power on the grid.

According to the U.S. Department of Energy, when intermittent sources such as solar or wind reach about 20 percent of a region’s total energy production, balancing supply and demand becomes extremely challenging: rolling blackouts can sometimes become inevitable. The same problem exists elsewhere, notably in Germany, where a vast photovoltaic capacity has sprung up thanks to generous subsidies.

The article proposes several reasonable solutions for storing power for use when there are lulls in wind or sunlight. All, however, appear costly, and all appear to end up making fossil fuels themselves more cost effective. For example,

A pumped-hydro facility consists of two reservoirs with a substantial drop in height between them. When there is excess electricity to go around, electric pumps move water from the lower reservoir into the upper one, thereby storing energy in the form of gravitational potential energy. When wind and solar wane or simply cannot keep up with demand, operators let water flow down and through turbines, generating electricity. In compressed-air facilities, excess electricity pumps air into underground caverns, and it is later released at high pressure to turn turbines.

Pumped hydro has been used for decades to balance the load on large U.S. grids. About 2.5 percent of the electricity used by U.S. consumers has cycled through one of these plants. In Europe the amount is 4 percent and in Japan 10 percent.

Reading this, I immediately asked, why not use this technology now to help reduce the amount of fossil fuels you need to burn? Japan seems to have figured this out. Why not us?
