Ramlal auto electrical shop will void the warranty and servicing of these karts. Manufacturers will not review that kart .
Ramlal just does not have the skill or access to the parts or kits to service the motor train or batteries.

Simple island folk that can't get shitt right will get Sunny and Tiida parts from the Bamboo and ride a Maxi until the parts come in. You'll be just fine.
There will likely be a significant number of BEVs on the road worldwide soon with 50% of all new personal vehicles projected to be electric by 2030 in the UK, Europe, Japan, China, and S. Korea; and about 30% in the USA. Trinidad, Guyana, Haiti and Nigeria probably won't hit those numbers.
You don't want an EV? Don't get one. But the ICE selection of right hand drive vehicles is going to get tighter. Meanwhile, other people will be solar trickle charging their cars to save enough money to buy a new battery or motor - if/when they ever need one.

Donkeys are born every day , they pull some article off the net that gets paid by the manufacturer to promote their karts. These same Donkeys have never worked in the electrical or electronic engineering environment to know any better.
Donkeys live in a theory world without any proven methods. They believe what they read.

The manufacturers can shut down any of the electrical or electronic parts via GPS once tempered with.
Sure bamboo can sell u used kart electrical parts but once the parts are swapped out they need to be configured by the manufacturer to be operable. You just can't swap electrical parts like that.
Even in the cycling industry where they now use power meter pedals , you just can't change the electronic parts from one pedal to another pedal. They are all activated by the manufacturer via GPS and online.

First, the word is "tampered".
You can't "shut down any of the electrical or electronic parts via GPS." GPS is received as a simultaneous set of broacasts. GPS satellites don't receive.
If immobilization is what you're talking about, that is software that relies on a receiver of the immobilization signal.
Car parts that you have today, keyfobs, head units, engine control units, also have requirements for interoperability programming - you just don't have the hardware and the software development kit to burn new instructions to the hardware. When that fails, you swap the control IC. Not much difference between interoperability programming and performance ROM tuning.
So don't tell me about how shitt can't be done. You just have no fukking clue on how to do it.

esla service center frustration:
Tesla does not allow its owners to repair or work on their vehicles. Except for adding washer fluid, you have to take your car into a Tesla Service center for all types of repair or maintenance. The problem arises here.
First, there is a limited number of Service Centers in each state.
Second, you have to make an appointment to fix your vehicle. Sometimes, these appointments could be after months.
Each quarter, Tesla is selling hundreds of thousands of vehicles. But the number of the service center is not increasing rapidly. Most of the owners told us that the quality of the Tesla service centers is deteriorating each day. They don’t respond to email and do not receive phone calls. Even if you make an appointment through the Tesla mobile app, your repair could take weeks. Moreover, if they don’t fix your car on time, there is no way to escalate the situation to higher management.
Frequently you will see on twitter that Tesla owners complaining to Elon Musk about their service experience.
While your Tesla is in the service center, Tesla may or may not give you a loaner vehicle depending on your location. So, at that time, you would be without any car.
Moreover, if you live in a country where there is no service center, what would happen? It’s complicated.
Phantom battery drain:
If you park your Tesla overnight, it will slowly discharge its battery. Tesla owners call it the Phantom battery drain. According to the Tesla owners manual, every Tesla battery discharges at a 1% rate per day. So, if you intend to park your vehicle at an airport, you need to keep this in mind. For example, if you leave your car for 2 months, the battery will discharge 60%.
If your battery discharges to 0%, it could damage onboard electronics. Moreover, the lithium-ion battery recharges the onboard 12V battery. If the 12V battery becomes dead, you won’t be able to unlock your Tesla. In that case, you have to tow your vehicle to the nearest electric charging station.
Less range on highway driving:
On a typical gasoline vehicle, highway driving has better mileage than city driving. For example, in a Toyota Camry, you can go up to 500 miles on the highway on a full tank. However, in the city, you can drive a maximum of 300 miles. On Tesla, the opposite is true. Tesla cars have better city mileage than on the highway. So, on a road trip, your Tesla would not go it’s rated range.
You can’t tow with a Tesla:
Theoretically, you can tow with your Tesla. However, Towing would decimate the range of your vehicle. According to owners — though it depends on how much you are pulling — towing could decrease your Tesla’s range up to 50%. So, a 400 miles Tesla would become 200 miles Tesla. It is frustrating. Because on a long road trip, it means you need to recharge your vehicle too often, increasing your travel time significantly.
Lackluster interior:
Tesla vehicles are expensive. But the interior is not luxurious similar to other cars such as BMW or Mercedes in the same price range. In short, the interior is plain and simple.
Tire wears out fast:
Tesla’s are heavy vehicles. It also has a very high torque compared to a gasoline vehicle. It is why tires in Tesla wear out fast. So, if you own Tesla, you need to change tires more frequently, increasing your ownership cost.
OTA update could bring new bugs:
Previously we said that the OTA update is an excellent feature because Tesla can introduce new features and improve the vehicle even after vehicle delivery. However, according to Tesla owners, sometimes the OTA update introduces new bugs, and Tesla takes a long time to fix these bugs. Moreover, it’s tough for owners to report these bugs.
Cold weather range degradation:
If you live in a colder climate, your Tesla will lose range in cold months.
Not suitable if you live in an apartment:
If you have a house, you can recharge your Tesla at your home. However, if you live in an apartment, it could be challenging for you to recharge your electric car if there is no supercharger or destination charger in your area. Mostly it is problematic for those who live downtown. Moreover, some Tesla owners said their HOA did not agree to put any charger in the community garage.
Battery degradation:
Tesla’s battery degrades over time. Tesla owners said that over a few years, Tesla’s lost almost 10% range. In a colder climate, this degradation could be worse.
Poor build quality:
Tesla is famous for its technology but not for its build quality. Panel gaps, rattles, and paint issues are a common problem. For example, a Tesla owner found a home depot-grade fake wood in their car. Here’s the article – https://www.thedrive.com/tech/36274/tes ... -fake-wood.

The Ministry of Energy and Energy Industries said its awaiting the finalisation of a policy for solar feed-in tariffs which will allow the Trinidad and Tobago Electricity Commission (T&TEC) to pay homeowners for the energy they produce.
Hannibal Anyika, Senior Sustainable Energy Development Analyst at the Energy Ministry’s Renewable Energy Division, said a revised policy document is due to be submitted to Cabinet by the end of this month.
Anyika was speaking on May 3 at a webinar hosted by the Office of Disaster Preparedness and Management on Disaster and Climate Change Risks in Trinidad and Tobago.
Anyika said the setting up of feed-in tariffs will make solar energy systems more affordable for homeowners as well as enable them to be paid for the energy they supply to the grid.
“A major policy we’re currently finalising is the feed-in tariff which would basically address bringing renewables for small and medium-scale installations.”
“At the utility scale, the law doesn’t define the source of energy, however at the small and medium scale T&TEC and the RIC doesn’t envision the homeowner feeding into the grid or selling power to T&TEC….the sale of power is basically controlled by a power purchase agreement.”

Simple island folk that can't get shitt right always reach the wrong fuckking conclusion because they only see shitt that isn't there.
The LCOE of utility scale solar is about one-fourth the LCOE of home generated solar power. Wind power's LCOE is typically cheaper still.

i was right about those, didint see how heating a drum 500ft inthe air to 500deg c would be cost effective.
home solar set ups, dumping on the grid is the way to go for us dumb island folks. cause industrial and comercial places simply dont have the surface area to do it. they would need large solar and wind farms to do that, and thats just not wise on a small dumb island.
the batteries is a problem. the biggest problem. by the time it finish work back the carbon deficit to manufacture, it done gone down in life span.
windmills, our winds too variable, them ting will wring out and mash up before it make back the money
[whine] the windmill designed to be variable and it does withstand high winds inthe nordic countries[/whine]
we will not buy those , we will buy some crap like the wgtl plant that will mash up.
do the solar home systems, and we will jess burn natural gas from 4pm to 8 am,,, save 8hrs of natural gas.
sMASH wrote:do a lil better research, dem ting not as effective as presumed. they not making the kinda output, for the comparable investment cost as pv cells. and the day to day viability of all those mirrors adjusting is leading to too much failures and associated replacement costs.
In new studies led by researchers from the National Renewable Energy Laboratory, the US Department of Energy pursues an energy cost goal of $0.05 per kilowatt-hour.
The Gen3 CSP program targets an energy cost of $0.05/kWh. The DoE has identified opportunities in three material pathways: storing heat in sand-like particles, in liquids like molten salt, and in gases, such as the technology developed by Brayton Energy. The DoE selected particle-based storage as the main method for its funding, but also opened the door for NREL to run a two-year liquid molten salt research program.

Since the Solar Energy Technologies Office (SETO) launched the SunShot Initiative in 2011, solar has made great strides in the United States. In early 2011, solar power comprised less than 0.1% of the U.S. electricity supply with an installed capacity of just 3 gigawatts. As of 2017, solar now supplies more than 1% of U.S. electricity demand with an installed capacity of more than 47 gigawatts.
The solar office has continuously worked toward its goal of enabling solar electricity costs to be competitive with conventionally generated electricity by 2020, without subsidies. During this time, the solar industry has seen tremendous progress in cost reduction. In 2017, the solar industry achieved SunShot’s original 2020 cost target of $0.06 per kilowatt-hour for utility-scale photovoltaic (PV) solar power three years ahead of schedule, dropping from about $0.28 to $0.06 per kilowatt-hour (kWh). Cost targets for residential- and commercial-scale solar have dropped from $0.52 to $0.16 and from $0.40 to $0.11 per kWh respectively.

The Crescent Dunes Solar Energy plant.
The photos of the 10,000 mirrors arrayed around the Crescent Dunes Solar Energy plant are striking and seem to suggest the futuristic concept is on a path to efficient, reliable, and cost-effective renewables.
But, after years of accusations of mismanagement and unreliability in providing power, the plant’s operator, Tonopah Solar Energy, threw in the towel on 30 July and filed for Chapter 11 bankruptcy protection, recording about $430 million in secured debt owed to the US Department of Energy (DOE). It is seeking a settlement under which DOE will recover less than half of the original loan, around $200 million, according to documents filed in US Bankruptcy Court District of Delaware.
Signs of trouble became evident last October when the developer of the project, SolarReserve, filed a lawsuit against the DOE and Tonopah Solar Energy, alleging the DOE interfered with its “right to participate in the management” of Tonopah Solar Energy. Just 2 days later, Nevada Energy, the largest electric utility in the state, provided a notice of termination on its 25-year renewable power-purchase agreement (PPA) with Tonopah, which was originally set to end on 31 December 2040, because of “frequent and prolonged outages.”
What Went Wrong?
In 2008, an affiliate of SolarReserve formed Tonopah Solar Energy LLC to develop, own, and operate the plant. In 2011, the DOE issued a $737-million loan guarantee to help finance the $1-billion 110-MW concentrating solar power plant near Tonopah, Nevada. It was described as the first deployment of solar power tower technology in the US to use molten salt as a primary heat-transfer fluid.

How a Concentrating Solar
Power Plant Works
CSP technology uses heliostat mirrors that reflect solar radiation to heat molten salts passing through a series of tubes installed on a central receiver tower. The molten salt is then transferred to a large insulated tank for storage.
The hot molten salt from the insulated tank is passed through a series of heat exchangers to produce highly pressurized superheated steam. The steam is used to run a conventional turbine to generate electricity.
Surplus thermal energy is stored in the molten salt and can be used to produce additional power for up to 10 hours.
More than 10,000 mirrored heliostats concentrate sunlight on a 640-ft-tall central tower and heat the molten salt inside to more than 1,000°F. The superheated mixture is then used to boil water to generate steam and drive steam generators to produce power. The molten salt storage was touted as allowing the project to generate power at full load on call for up to 10 hours without any sunlight.
SolarReserve said the patented storage system can deliver electricity on demand like a traditional coal or natural-gas power plant but with zero emissions, little water use, and no hazardous waste.
The plant was approved by the Nevada’s Public Utilities Commission in 2010 but did not begin commercial operations until 2015.
Less than a year later, in October 2016, repairs to fix a leak in a molten-salt tank took the plant offline for 8 months. NV Energy, the plant’s only customer, said in a June 2019 report that the frequent, prolonged outages at the plant reduced the expected amount of energy and credits by 50% in 2019 and 25% in 2020 and beyond.
NV Energy said, “Given the size of the project, Nevada Power simply does not have enough credit reserves nor sufficient new renewable capacity in the pipeline to overcome lasting, multiyear credit shortfalls.”
Custom parts and dozens of staff were required for daily operations and to conduct maintenance regularly on the steam generators and heat exchangers. When the plant finally opened in 2015, solar panels had left the CSP technology in the dust in terms of efficiency and cost.
The high tech was obsolete before it was up and running.
Crescent Dunes was selling its power at about $135/MWh, while Techren Solar II in Nevada’s Eldorado Valley priced its power at approximately $30/MWh.
The death knell sounded last summer with a catastrophic failure of the molten-salt storage tanks that caused ground contamination and required the removal of the solar tower. The DOE sent a formal default notice in September, followed by NV Energy’s termination of its PPA.
SolarReserve contended in its lawsuit that the LLC agreement gave it the right to appoint one of the managers of Tonopah. But, according to the lawsuit, the DOE sent a “notice of default” letter only days after SolarReserve had appointed a new manager. The lawsuit said the DOE wanted to appoint two new members to Tonopah’s board of managers, “which gives the appearance of the (Energy Department) in complete control of Tonopah through its handpicked ‘independent’ directors which comprise the entirety of the Tonopah Board of Managers.”
This precluded any representation of SolarReserve on the board, which meant major decisions requiring a unanimous vote such as bankruptcy proceedings stifled input from the developer, the lawsuit alleged.
The blame game has been in full swing with finger-pointing to and from the developer, SolarReserve, general contractor Spanish company ACS Cobra, and owner Tonopah Solar. Cobra is being blamed for the delay in completing the construction of the plant and the allegedly faulty design of the molten-salt tank.
According to the bankruptcy filings, Tonopah is owned by SolarReserve, the startup that developed the plant; Cobra Energy Investments LLC, a division of Spanish infrastructure company ACS; and Banco Santander SA.
Moving to Higher Tech
NV Energy moved on and signed a 22-year PPA with EDF Renewables North America on 29 July. The power will be generated by the 200-MW Chuckwalla Solar+Storage project to be built by EDF. Located on the Moapa Band of Paiute Indians Reservation, 35 miles northeast of Las Vegas, Nevada, the project will include batteries that can store 180 MW of power for 4 hours. The Chuckwalla Solar+Storage project is expected to come on line in late 2023.
“EDF Renewables is pleased to strengthen our relationship with NV Energy, building on our 2019 agreement to develop and build the Arrow Canyon Solar+Storage project,” said Ian Black, vice president of west region development at EDF Renewables North America.
Arrow Canyon is also being built on the reservation. It will be a 200-MW solar project that includes a 75-MW/5-hour battery storage project and is expected to be up and running in December 2022.
“The battery and solar system work together to provide more energy during the summer evening peak hours, when system needs are the greatest,” Ian Black, a vice president at EDF Renewables North America, said in a statement. “NV Energy can utilize the battery at their discretion in all months of the year, allowing mitigation of demand spikes.”

ur saving the skies, but poisoning the land. and until u get more wind and solar, its just shifting the combustion from the individual to the corporation.
A coal-fired power plant is between 35% and 42% efficient.
A natural gas power plant is 60% efficient.
The best ICE efficiency is 25%.
Batteries are already being manufactured that improve cost, performance and environmental impact.

The Aqua has an "EV" button. When conditions are right (battery charge and throttle position), it is possible to drive your car in electric vehicle hence "EV" mode for very short distances. At any moments notice, the ICE kicks in to propel the car forward and to recharge the battery.Les Bain wrote:agent007 wrote:In some Hybrids, this is not possible.

As in the case with a large chunk of Hybrids on our roads, this group I'm referring to is the (Prius C, Aqua, Axio Hybrid, Fielder Hybrid, Sienta Hybrid) - that's a couple thousand there already
Those Hybrids have a slightly different version of the popular ottocycle 1NZ-FE found in a bunch of Toyotas, mainly the E12x and E14x Corollas.
The engine code in the Hybrids would be 1NZ-FXE which means it operates under the Atkinson combustion cycle for better fuel efficiency but with lowered output.
If the Hybrid Synergy Drive (HSD) system fails with electric motor or the P510 (eCVT) transmission or the battery pack itself, the ICE alone will not be able to propel the car forward safely and properly as the engine was designed to work in conjunction with the electric motor.
This would be similar to the Prius and Prius Alpha that has an HSD system paired with the 2ZR-FXE which is the Atkinson derivative of the regular 2ZR-FE.
For the Xtrail Hybrid, if the Hybrid system fails, the ICE may not be affected however the vehicle won't go anywhere as was reported in several instances.
It appears when the Hybrid System error comes up, it can shut the vehicle down into a safe mode or simply won't allow you to move the vehicle unless it's towed and code cleared, as in problem fixed.
Open to correction. But as I mentioned, even if the Aqua does start and limps forward, that's exactly what will happen...limp is the word.
The Xtrail on the otherhand does not use an Atkinson cycle engine as Toyota did with theirs. The MR20DD is basically the same unit found in regular Xtrail T32's and the Qashqai J11's with the exception of the electric AC compressor etc.
You sound knowledgeable so you may be able to answer.
Despite being hybrid are any of these systems you mentioned able to go a limited distance on electric power alone, like the McLaren P1? Like say you have to go to the neighborhood parlour and don't want to walk or burn gas?
Absolutely correct bro. The gas consumption will be higher if those owners are running their vehicles without the HSD system. You see, they are pushing an engine that runs on the Atkinson combustion cycle without the help of the electric motor to propel the vehicle. That engine would be straining and that eCVT can be destroyed because it would be running on a higher rev and those eCVTs cannot take heat. It would significantly defeat the core purpose of acquiring an Aqua in the first place.Musical Doc wrote:agent007 wrote:In some Hybrids, this is not possible.

I can't personally dispute your statement on the HSD since it hasn't happened to me as yet, but I'm on the fb Aqua group and there are people on the group whose hybrid battery has failed and they still able to use their car. The only difference is that the gas consumption will be higher since the engine will be running constantly, which kinda defeats the purpose of a hybrid. Also, I've read that there is a way to but your aqua in a "gas only" mode where the EV doesn't kick in. This was something I read on the fb group again
