The use of blood to make concrete
In 1980, Charles Laleman of France received a US patent (No. 4,203,674) for a technique for making concrete by mixing together cement with blood. His patent described a variety of different recipes one could use to create this blood concrete. For instance:
A light colloidal concrete is prepared by using:
a commercially available cement (cement CPA 400), a silico-calcareous sand graded no higher than 0.8 mm (the cement/sand mass ratio being equal to 1), whole blood powder of animal origin, a colloid, and mixing water in variable proportions.
The various constituents are mixed by means of a mixer working between 100 and 600 r.p.m.
The advantage of using blood, Laleman argued, was that the oxygen in it produced a lighter concrete.
Curiously, Laleman acknowledged that the idea of using blood to make concrete wasn't in any way new. He cited a variety of earlier patents, such as US patent 1,020,325 from 1912 which described mixing blood into concrete. And, in fact, the technique of using blood to make concrete was even practiced by the ancient Romans.
What made Laleman's technique unique (and therefore patentable) was apparently that he used it specifically to lighten the concrete, rather than to color it or to make it more porous. That seems like a rather fine distinction to me, but it was enough to earn him a patent.
Laleman's list of earlier patents includes another oddity. He refers to US Patent No. 3,536,507 (from 1970) which describes making concrete by combining cement with "an admixture which is derived from the fermentation liquor resulting from the aerobic fermentation of liquid carbohydrates, e.g., molasses from beet or cane sugar, corn, wheat or wood pulp." That sounds like a fancy way of saying they were mixing cement with beer.

A Queer Ferry
I would call this an aerial tramway for cars. Seems it would have been much easier just to build a bridge!

We can still do this. A nice walk to the Statue of Liberty on Landfill Manhattan.

When Havoc Struck
It's never news or entertainment when something goes right, only when it goes wrong. The 1978 TV series WHEN HAVOC STRUCK knew what people wanted. Glenn Ford must've needed a paycheck.

Giant Grocery Cart
The Shopper Chopper is the world's largest shopping cart and you can hire it for events! Reminds me of the cart races in the movie Jackass!

Home heating with beer cans
Back in the late 1970s, Bill Tolle of Woodlawn, Ohio figured out a way to use empty beer cans to heat his home in the winter. Basically he made a solar heater, with the empty cans trapping the sun's heat. But the beer can angle perked the media's interest.

With the recent migrant tragedies at sea around the globe, we must always recall one of the great refugee success stories: turning an old Detroit truck into an ocean-going vessel.

Recycled Water Shower
Use the same water for weeks?This shower recycles, purifies and then reheats the same water over and over again -- saving water and electricity. Designers claim this shower will use up to 30 times less water and a fraction of the electricity. Since the water is already warm, it needs to be reheated less than cold water. Users would save thousands in energy costs.
Here's the link to the story:

Developers are thinking of expanding this technology to car washes, washing machines, and other water intensive uses. Water parks?
