Human Waste-Powered Robots

Unos científicos de la Universidad de Bristol (UK) están trabajando en un robot auto-sustentable llamado “EcoBot III”, una maquinita que come materia orgánica para generar su propia energía, la digiere, y la elimina como lo haría cualquier organismo vivo.

Parece el sistema de fusión perfecto (el mundo está lleno de materia orgánica), y el principio de una nueva generación de maquinas “ecológicas”, capaces de sobrevivir en un ambiente natural y seguramente en el futuro, autómatas (cómo ya las hay).

La idea de este invento no es nada nueva. A mí por ejemplo me recordó al “Mr. Fusion”, de la película Back to the Future, que es un reactorsito portátil -traído del futuro, claro- que provee energía al De’Lorean del Dr. Brown alimentandose sólo con basura orgánica (una cáscara de plátano, un trago de cerveza y no recuerdo qué más).

Ver esta tecnología realizada y funcionando es increíble. Solo hay un pequeño problema: los humanos también somos seres orgánicos, ¿no? Así que estos robots en teoría podrían comernos (y hasta defecarnos) para subsistir. Eso lleva el asunto totalmente a una cuestión moral, y lo encierra en ella. ¿Realmente queremos crear máquinas inteligentes, capaces de comerse todo lo que hay en nuestro entorno, incluídos nosotros?

Espero que Morpheus (el personaje de la película “The matrix”, 1999) no tenga demasiada razón cuando dice:

“Fate, it seems, is not without a sense of irony”

Today’s robots that fly, jump or roll around must refuel or recharge as does any gadget that runs out of energy. Tomorrow’s new generation of self-sustaining robots might keep going nearly forever by grazing on dead insects, rotting plant matter or even human waste.

The vision of robots capable of plugging themselves into the natural world of living organisms has begun taking shape in several labs around the world, and even NASA has shown renewed interest in powering space robots with microbes. But one British lab has already been building on the work of robotics pioneers to create small “EcoBots” that extract energy from microbial fuel cells since 2002.

“Robots that eat biological fuels could find enough fuel almost anywhere,” said John Greenman, a microbiologist at the Bristol Robotics Laboratory, a joint venture between the University of the West of England and the University of Bristol. “There is organic matter anywhere on Earth — leaves and soil in the forest, or even human waste such as urine and feces”…

Gravity Light

Este invento sí parece como traído del futuro: lámparas que generan luz eléctrica a través de la fuerza de gravedad.

Imaginen las posibilidades de aprovechar esta vieja y conocida ley física, que en nuestro planeta sobra (y tan antigua como él mismo), pero convertida en fuente de energía. Quiero ver más de esto…

It’s an innovative way of generating light and low levels of power from gravity. It takes only 3 seconds to lift the weight that powers GravityLight, creating 25 minutes of light on its descent.Benefits Can be used over and over again, anytime No need for sunshine or batteries No running costs Long lasting…

Balls on escalator

Alguien tuvo la genial idea de soltar muchas pelotas en un escalera eléctrica para crear esta suerte de “evento kinético”. Aun no se quien lo hizo ni porqué. Ni si quiera sá si importe saberlo. Pero el efecto logrado es un gran eye candy. Gracias boingboing

It’s almost a perpetual motion machine, and is absolutely a source of infinite amusement! (via JWZ)

Canned Radiation

Este y otros “souvenirs” forman parte de una curiosa colección del centro de investigaciones de energía Oranau, en Tennesse, E.U.

“Canned Radiation” from Three Mile Island produced  by Brenster Enterprises of Etters Pennsylvania.
This was probably the most popular souvenir associated with the accident at Three Mile Island. 

The six suggested uses indicated on the label were:

1. Remove label and tell your enemy its laughing gas.
2. Energy free night light (illuminates in darkness).
3. Mix with cold cream for that radiant beauty.
4. Instant male sterilization (sniff twice daily).
5. Use as a room air freshener.
6. Toothpaste recipe: mix 3 to 1 ratio with baking soda, for ever glowing smile.

Size: 4.5" high, 3" diameter.

Biological light

Plantas genéticamente modificadas para generar su propia luz. Un invento de la compañía estadounidense BioGlow, con la novedad de que con esto, la iluminación en el futuro no se va a obtener comprando focos. Se va a cultivar.

By splicing genes from a bioluminescent bacteria with a common decorative plant calledNicotiana alata, engineers have created the first biological light source for your home. This is the first glimpse of a future world where synthetic biology transforms our lives.

Called the Starlight Avatar, this plant is being touted by company Bioglow, which created it, as the “first” light-producing plant. There are many kinds of algae and animals that glow, but this claim may be technically true. The company is auctioning off the first set of grown plants, and taking pre-orders for ones that they grow later this year.

The plants don’t give off very much light, but they are just the forerunners of other GMO species that could be used to make our living spaces more sustainable and beautiful. I love the idea that future city inhabitants might be farming their lights instead of changing light bulbs…

Artificial trees

The company, Solar Botanic, has created a fully artificial tree capable of generating enough electricity for a house and reduce the home owner’s dependence on the public power grid. The “trees” take advantage of the wind, light and heat they’re exposed to while outside. Solar Botanic’s website refers to these three technologies as piezovoltaic, photovoltaic and thermovoltaic, respectively…

The secret to Solar Botanic’s tree’s are in the leaves. Called Nanoleaves, each one functions as a tiny wind-harvesting/sunlight-gathering/heat-absorbing device. They’re green, which makes them slightly less less efficient at gathering sunlight than conventional solar panels, but they do have a better consumer asthetic.

A description on Solar Botanic’s website says, “The more wind there is, the more Nanoleaves are moved.” And, “The stronger the wind, the higher the ‘flap’ frequency, and therefore the larger the watts generated.” Plus, falling raindrops can also producing electricity by stimulating leaf movement. Though each individual movement, warmth or ray will only generate picowatts of power, hundreds of leaves on a single tree can combine to generate a siginificant wattage.

According to Solar Botanic, a broad leaf artificial tree resembling an oak or a maple could generate 3500kWh and 7000kWh per year, and an evergreen could crank out 2500kWh to 7000kWh per year…

walking power

Otro de esos inventos que pueden darle la vuelta otravez a la cuestión del consumo de energía (como pasó con los paneles solares y los motores eléctricos): ahora salió un dispositivo que aprovecha la energía mecánica de nuestros pies al caminar -que es mucha-, y la convierte en energía eléctrica. Según sus inventores en la Univ. de Wisconsin-Madison, las aplicaciones pueden ser muchas, comenzando por la posibilidad de cargar la pila de los celulares y otros dispositivos similares…

(Discovery News) – Basically, it means you could put a layer in the sole of a shoe – similar to the liquid-filled layers in some higher-end sneakers – and convert the mechanical energy of walking to electricity, and then transmit that to a device such as a phone. It wouldn’t replace batteries, but it would extend their lives by quite a bit. While solar power is an option for some electronics, sometimes there isn’t any sunlight, and the wattage that a small solar panel can generate is ususally enough for something like a calculator, but not a smart phone.

Krupenkin says the amount of energy humans can generate this way is quite large. A sprinter puts out nearly a kilowatt, and even walking along someone could generate about 20 watts – plenty to top up the average cell phone battery. The power could be transmitted wirelessly…
