About Renewable Energy
Renewable energy is energy that is collected from renewable resources, which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat.

H2Go Power is trying to power drones with a 'happy gas"
to take care of If you are thinking, hydrogen and air, The Image That comes to, for the majority of the airship Hindenburg In Flames .
But in a laboratory deep in The Basement of the Imperial College in London, a young team has built what he believes is The Future of the air.
H2Go is to save on the search for Power, a patent, the explosive gas-safe and convenient.
today is the storage of hydrogen required is ultra-strong and large tanks That can withstand pressures of up to 10,000 pounds-force per square inch (psi). This is hundreds of times greater than what a tyre in a car.
But, while studying for her PhD in Cambridge, and Dr. Enass Abo-Hamed came up with a revolutionary structure, the storage of hydrogen as a stable, solid and without compression.
"the pressure is similar to what you would Get In a coffee machine," she says.
The University coupled with materials scientists, Luke Sperrin, to find to try, the commercial applications for innovations and H2Go Power was born.
Test flightDr. Sperrin is now chief technology officer. He and Dr. Abo-creating Hamed, which is a partnership with the Canadian hydrogen fuel cell manufacturer Ballard a year ago, a drone, the reactor for safe storage of hydrogen for the flight.
Finally, after months of collaboration by phone and email, Mr Sperrin and chief product developer Peter Italiano flew to Boston for a groundbreaking test flight.
"of course you need really good weather for flying a drone," smiles Mr Sperrin.
"And it poured with rain for The First few days. We were not even sure if we will even be able to go forward.
"So, if it flew, it was a huge Relief . "
hydrogen-powered drone developed, the Power of Ballard and H2Go, How it works.The aluminum reactor weighs less than a bag of sugar.
The small cylinder has a complicated network of 3D-printed aluminum tubes in the interior.
The hydrogen remains stable in these structures, the "coolant" is pumped through the pipes, it warms and release of hydrogen gas is pumped to the drone, the fuel cell
hydrogen (H2), a side of the fuel cell is freed from the catalyst, the electrons, creating Electricity .
oxygen (O) is then pumped into The Other side of the fuel cell and combines with The Left , positively charged hydrogen atoms (H+).
The only final waste product is water vapor (H2O).
Never-ending supplyUntil recently, a major barrier to affordable hydrogen technologies, as well as the costs for the production of hydrogen gas.
the cleavage of water molecules in hydrogen a lot of energy That came from fossil energy sources consumed.
But the widespread availability of renewable energies and improvements in the electrolysis - chemical process for the separation of elements of power is brought about the financial and environmental cost of the production of hydrogen for fuel.
at the moment, most countries have strict safety rules about flying drones over heavily populated areas.
collision or technical errors may lead you to drop a drone out of the sky.
Lithium-ion (Li) batteries are highly flammable, so That a crash can cause an explosion.
But, Dr. Abo-Hamed points out, even if your drone fell from the sky, the hydrogen remains stable in its solid form in the interior of the reactor.
Dr. Enass Abo-Hamed got the idea for the hydrogen reactor, while working on her doctoral thesis on Super-fuel"hydrogen is a gas," says Dr. Abo-Hamed. "Move it wants to. "
This is what makes it so explosive. But, it also delivers more bang for your buck.
hydrogen is substances That produces Three Times as much energy per kilogram compared to fossil fuels - how 39. 0 kilowatt-hours per kilogram, compared with about 13 kWh per kg for kerosene or petrol, or simply 0. 2 kWh for conventional lithium-ion batteries.
this means That a hydrogen-powered drone can carry to fly further than a battery-powered drones, and potentially heavy loads.
Dr. Abo-Hamed is excited about the possibilities for your Innovation .
"So, if drones could stay longer, in the sky, in the medicine can afford," she says. "Or a scan in a disaster area and send The Information back.
"My dream, is not it hum, actually, only.
"Maybe in the next twenty or thirty years ago, we were de-carbonise air travel in the location, this is something really important for our climate. "
