Image Credit: Solar panel, wind turbine & globe via ShutterstockCleanTechnica is the #1 cleantech-focused website in the US and the world according to Compete.com and Quantcast.com.

Our work has been referenced by the New York Times, Washington PostSlateMSNBCThink ProgressReutersScientific American, and plenty of other sites. Some of the cleantech industry’s top CEOs, directors, founders, and board members read us regularly. But plenty of “common citizens” are also addicted to our site.

CleanTechnica strives to be (er… remain) the most indispensable website on the planet for cleantech news and commentary. We have been covering the cleantech industry obsessively since 2008, before it was popular for mainstream media to dedicate blogs or subdomains to the topic, and we are now a well-recognized leader in this field.

Recognition from Around the Interwebs

The following are just some of the indications that we are a top site to follow or reference for cleantech news, facts, or commentary:

But What is Our Focus?

Technology-wise, our focus is solar power, wind power, energy efficiency, and clean transport. However, we also get into many other topics — geothermal, hydropower, nuclear power, climate change, energy storage, and more.

Overall, I think our top goals are to:

  1. inspire people and help them to take cleantech action in their lives;
  2. share correct information on cleantech, including debunking widespread myths and horrible coverage in the mass media.

All in all, we want to be a useful site for the world and want to develop a strong, useful community of world citizens in order to help move humanity forward in a positive direction!

    POWER GENERATION – NEW ERA
    In Hydro Electric Power Generation Projects, we are
    generating Power with the help of accumulated water in Reservoirs at height. We utilize the down flow water Pressure to
    rotate Turbines.
    In this Project, we use people weight coming down
    from height, to rotate Turbines.
    For example,
    a) On Tirumala Hills, there will be 50,000 people at all times for generations together and daily. 1, 00,000 people are coming down and going up Hills for Lord Balaji Darshan. We can use their movement in Power Generation using Roller Coaster Technology.
    Power Generation calculations on Tirumala Hills.
    From SRIVARI METTU to Tirumala Hills the Slant
    Distance (say) 2 K.M. = 2,000 meters.
    Power Generation on Tirumala Hills. Calculations theoretically with formulas.
    From SRIVARI METTU to Tirumala Hills the Slant Distance (say) 2 K.M. =
    2,000 meters.
    Approximately, how much Power Can be generated when 10 Tons Load
    (8 Tons Bus + 2 Tons for 50 Passengers in the Bus) slides down on trolley.
    Tirumala Hills 2,000 meters distance
    Srivari Mettu (steps way)
    A layman’s — ‘Power Generation Calculations’. – 550 M.W.
    As per notes from attachment, (Work & Energy Chapter – PAGE 6) the following is the ‘Power Generation Calculation’.
    Please follow Link:- http://www.onlineconversion.com/energy.htm
    One trip – 10 Tons Load (20 – Passenger filled car weight 2 Tons + 8 Tons Bus weight) generates 278 watt per hour as per enclosed attachments. –
    formula:- (load in kgs x gravity x ½ distance)
    10000 x 10 x 1000 = 10,00,00,000 Joules = 27777.8W
    27,778 Watts per hour
    To transport up & down Hills, Pilgrims –
    1,00,000 per day @ 50 persons in Bus per trip, the RTC will ply down 20,000 trips 20,000 trips per day
    For every Trip load the Power generated will be 28 K W
    For 20,000 trips down 560 m w

    http://www.sciencechannel.com/video-topics/engineering-construction/machines-rollercoaster.htm
    These images are showing Public coming down on Roller Coaster in open cars, whereas, in our Project, we can arrange cars enter in closed Chambers, which roll down. These cars filled with Pilgrims who are chanting ‘Govinda nama sankeerthan’ during journey. In other words, we are providing ‘Garuda Seva’ to Pilgrims by transporting them up & down.
    b) At Chennai Central Railway Station, passengers getting down will move to Park
    Station to reach various parts of City through sub-urban Railway. A very
    little per cent age of Public depend on their own vehicles, 3- wheelers or
    Public Transport.We can shift the people from Chennai Railway Station to Park Station using Roller coaster Technology and also we can generate Power using their weight. We can arrange 20-seater Passenger trolleys in racks readily available on the platform. When Passengers getting down, they will be collected in trolleys and lifted to a height, say 30ft in the Chennai Central Railway Station Building and then Rolled down to Park Station.
    With this Project, Power Can be generated and along with shifting of men / material between Stations.

    BENAGALURU RAIL & ROAD PATH WAY PROJECT
    _______________________________________________________________________________
    In the 24 hours of the day there may be 50 to 60 trains are ‘coming in’ and ‘going out’ of Benagaluru Railway Station. With every train bringing in 1000 passengers
    each, the number of passengers it is handling (1000 * 50) 50,000 people. And out of them (say) 5% will ‘go out / coming in’ in their own Vehicles, another 10% use Autos, the remaining passengers will come to Kempa Gowda Bus Station to go to their destinations through Buses.
    Can we provide them easiest way to reach the Bus Station?
    Project Name: – BENAGALURU RAIL & ROAD PATH WAY PROJECT.
    ————————————————————————————————————————————-
    People cross the Railway Platforms through “Foot Over Bridge”. The Foot over Bridge height say 30 ft height. If we use a Lift for another 30 ft height, totaling the height is 60 ft height. From that height at the Centre of the Railway Platforms to Bus station we provide, a Path Way. It is just like a RAMP. People come down easily to Bus Station without any hurdles, like crossing Platforms, parking area, subway, steps, etc.
    We can provide trolleys with 20 passengers (2 Tons weight approximately) each which can slide easily to the distance and save the time & energy of the Passengers.
    Advantages in this Project:-
    (1) There is no Private Property in between these two points – Rly Stn & Bus Stn.
    (2) The height of the Foot Over Bridge at Railway Station and the Ground Level at Bus Station may be more than 60 ft
    (3) In addition movement of men / material, there will be scope of Power Generation – By sliding the 2 Tons Load Trolleys on the Rails on RAMP along with Pathway.

    A layman’s — ‘Power Generation Calculations’. – .5 M.W.
    As per notes from attachment, (Work & Energy Chapter – PAGE 6) the following is the ‘Power Generation Calculation’.
    Please follow Link:-
    http://www.onlineconversion.com/energy.htm
    ———————————————————————–
    These calculations I made for Benagaluru Path Way Project.
    2Tons Load (20 – Passenger filled car) generates 278 watt per hour as per enclosed attachments. 2000 x 10 x 50 = 10,00,000 Joules = 278W
    When train arrives into Railway Station, let us say, 1000 Passengers reach, get down and use the Transport will be 800 nos. 800 Passengers will be transferred in 40 Loads (800/20 = 40).Loads
    For every ‘four’ loads the Power generated will be more than 1 Kilo Watt
    (4*278 = 1,112). 1 K W
    With the Passengers in one train (40 Loads) we can generate 10 Kilo Watt Power per hour. 10 KW
    With the Passengers from 50 trains per day, we can generate 50*10 = 500 (.5 MW) Power. 500 KW =.5 MW
    Concept & Design – Patent Application No.4110/CHE/2014, dt.22-08-2014
    How much Power required to lift 2 tons Load to 30ft height”
    “2000x10x9 ”
    2000 x 10 x 9 = 1, 80,000 Joules
    Hence, Power requirement to lift 2 Tons Load (20-Passenger trolley) to a
    height of 30 ft is: – 50 watt per hour as per following conversion link:

    You guys rock!!!!!!!

  • Mikeymike801302

    I am about to come into a clear title for about 80 acres of flat Florida farmland from my grandmother’s estate. I want to take all 80 acres and develop a solar and wind farm. I could pay for the up-front costs with a loan against the equity in the property, then sell the energy wholesale to Florida Power and Light. Whom would I contact first because FPL are incompetent.

  • binaya

    Hi, I want some information about solar powered lamp post suppliers in India. Can you give me the website and contact information please.

    • Bob_Wallace

      I doubt anyone here has that sort of information. I’d suggest you spend some time Googling to see who makes a quality product and then contact them to see if they have a distributor in India or if they ship.

      Here’s a company that turned up with a quick search for “solar powered street lamps”. http://www.solarstreetlightsusa.com/

      I know nothing about them but I’d put them on your list and look for other companies. Then do your due diligence by checking quality and reputation.
      CalTrans – the California State highway department uses solar lighting at some more remote sites. You might contact them and see if they have any recommendations.

      Also, this could be a great industry for India. This is not a product that would take a lot of engineering.

    I don’t know how I found CleanTechnica or how it found me, but I liked it from the first. I almost dropped it in the interests of getting less email, however, since it seemed to come almost every day.

    But I kept reading it. Now I wish it came every hour.

    Not really!!!! But thanks for being there and doing such a great job.in all respects:content, scope, concision, humor. Thanks!

    • http://cleantechnica.com/ Zachary Shahan

      Thanks a lot! :D

      Believe it or not, would love to cover about twice as many stories every day than we do. But it seems to be against the interest of our readers, and most certainly is against the interest of our writers (their pay would drop), so we don’t. :D
